Talk:3085: About 20 Pounds

172.70.230.63:

Wow - first here! I can't help thinking 'about 20 pounds' could be exactly 10 kg! 0r even one Newton?! [[User:RIIW - Ponder it|RIIW - Ponder it]] ([[User talk:RIIW - Ponder it|talk]]) 05:50, 6 May 2025 (UTC)
:"One Newton" and "10 kg" are totally different things. "10 kg" would cause 1 Newton of gravitational force if you were in a world with about 1% of Earth's gravity, though. --[[Special:Contributions/172.69.109.86|172.69.109.86]] 09:53, 6 May 2025 (UTC)
::Oops! In my rush I should have checked and put 100 Newtons. I was relying on 10kg being about 22 pounds, or rather the other way around, and then a particle having mass not weight and Science using Metric units. Apologies.

::(Moved your reply up a bit. You seemed to respond to "20 pounds are...", below, ''and'' split their timestamp signature from their message. And forgot to sign properly, at first, so I got edit-conflicted ''twice'' whilst trying to post myself and correct your initial error. Please take a bit more care, everybody.

:20 pounds are approximately 9.072 kg, so not exactly 10 kg (in fact, it rounds to 9). [[Special:Contributions/172.70.134.55|172.70.134.55]] 10:02, 6 May 2025 (UTC)
::That's the wrong way to think about it. "Exactly 10kg" is "exactly 22.0462lbs", but that (to the nearest single significant figure) is legitimately "about 20lbs". See any given step in [[2585: Rounding]], especially where that 'disagrees greatly' with an adjacent step.
::As with any Oracle (that's worth its omphalos), it may be giving an ''entirely true'' answer which nevertheless is deliberately phrased as ambiguous and misinterpretable, the possible supernatural complement to the 'exact words' genie contract. As with the [[2741: Wish Interpretation]] genie, the Oracle ''may'' slip into less "unhelpfully helpful" mode immediately after, though for different reasons. However, "burritos are ''pretty'' good" also suggests that there's some other thing that is ''more'' good, so — again — it's giving a sufficient response to what they (now) should do, but not a perfect one.
::As I write, the explanation (probably needs a general rewrite) doesn't mention anything about the burritos except as title text, or I would have ensured the famed exact-words/vague-detail was noted in that bit.

:Nobody said anything about "exactly 20 pounds". 20 pounds is about 10 KG and about 100 Newtons when considered as a force rather than a mass. The comic says "about 20 pounds". [[Special:Contributions/172.70.230.63|172.70.230.63]] 22:36, 6 May 2025 (UTC)
Though I don't think it at all merits being described as a reference, I am minded of the {{w|The Usenet Oracle}} (at least when I knew of it). Though, if it ''was'' to be a deleliberate shout-out, I'd expect a few more actual in-jokes. [[Special:Contributions/172.70.86.130|172.70.86.130]] 06:10, 6 May 2025 (UTC)

I bet Randall is in some kind of force-interaction-related, What-if-induced rabbit hole right now (or has been at the time of writing). Wondering what the next comic will be about. [[Special:Contributions/172.71.144.175|172.71.144.175]] 08:39, 6 May 2025 (UTC)

"Nature of ... 20 pounds" is a reference to the koan "A monk asked Tozan, 'What is the nature of Buddha?' He replied, 'Three pounds of flax.'" Someone can add this to the explanation. [[Special:Contributions/172.70.111.115|172.70.111.115]] 08:57, 6 May 2025 (UTC)
:There is a similar story in the Principia Discordia. When asked what is the meaning behind POEE, a Discordian cabal, Malaclypse the younger answered "five tons of flax." [[User:FlavianusEP|FlavianusEP]] ([[User talk:FlavianusEP|talk]]) 16:30, 6 May 2025 (UTC)

"something that doesn't interact with electromagnetism cannot be 'seen', as photons will pass through it completely unaffected": is this supposed to be true ? I thought photons interacted with gravity, and even the phrase before states that gravity is believed to affect everything. [[Special:Contributions/172.68.151.93|172.68.151.93]] 09:17, 6 May 2025 (UTC)
: Indeed, photons do interact with gravity. What I had in mind when writing that were ''direct'' interactions -- of course everything interacts with everything else via a second-order interaction, <X> -> gravity -> <X> for any particle/field <X>. I can clarify that if nobody gets to it before I get around to it. [[User:Linkhyrule5|Linkhyrule5]] ([[User talk:Linkhyrule5|talk]]) 21:45, 6 May 2025 (UTC)
:We can ''infer'' Dark Matter (and, for that... *ahem* ...matter, also Dark Energy) from what the photons in the universe are telling us that does not look anything like what 'light(-interacting) matter' ''should'' be doing. As with some searches for black holes (most particularly, when the theory is that the unseen mass of the universe is a lot of small black holes drifting in the void, not acreting enough to create secondary visible effects), whether or not light is being gravitationally lensed by things (that we cannot directly see) is part of the way that we're narrowing down what-and-where DM is.
:And, I think, currently it seems to be considered that it's residing in a webwork of DM tendrils, at extragalactic (indeed, cosmological) scales, such that where the tendril cross is where they draw 'normal' matter together enough to be any given galaxy. But that's in an "explains all(/many) known facts" way, and might yet be incorrect. e.g. if there's side-dimensions (equally undetectable, at least visually) that change the inverse-square dropoff of gravity at large enough scales to govern galactic rotation rates by just enough to fit observations, or we have some other misunderstanding/scientific blind spot that further study may correct.
:Or, in short, think Brownian Motion. We can't see a handful of air molecules (not by normal, even microscope-enhanced, human vision), they might as well be invisible. But, by what we see of more visible particles, suggests that they exist as something. Conversly, the æther, a proposed medium for light, was thought to exist in a similar all-pervasive manner (insofar as trivial human experience, though less physically 'interactive' than wind), but deeper checks (as to whether its effects on light were as they should have been) dismissed it as a possible concept.
:Depending upon interpretation of the comic (I originally read it as "all dark-matter particles are ~20lbs in mass WIMPs/nano-MACHOs/whatever", but it seems that others take it as "''all of'' dark-matter particles is a single ~20lbs mass particle"; and that's make the oracle-invokers' attitudes more logical, if not the universe), there actually being Dark Matter, but it being just 20lbs of 'something' ''somewhere'' in the whole universe, makes it a needle in a galactic-supercluster-sized haystack.
:Detecting ''that'' would be difficult in the extreme. Even if it's somehow within a few hundred metres of the experimenters. There are ways to {{w|Cavendish experiment|observe the movements of small masses at small distances}}, but when you don't even have a clue ''if'' it exists (or is moving/has moved, and how), it's fairly hopeless. Gravitational lensing of light would be impractical at such distances/masses. LIGO may be very clever, insofar as merging high-mass objects at long distances, but not really for this. Event Horizon Telescope's ability to see a black hole('s accretion disk) via Very Long Baseline Interferometry is also totally useless here.
:I think I'd ''also'' settle for the burritos, given that certainty that I wasn't going to find what I'm looking for via any obvious route. (Assuming I couldn't ask the Oracle to ''show me'' the Dark Matter, rather than just answer questions about it. And noting that, if not for the indicated progression of the conversation, I might have assumed the oracular voice were really from the pentagram (more usual for demonology, not oracularities!) and that the dark blob ''was'' the 20lbs of Dark Matter. Which, of course, it ''does not deny'', so maybe my headcan[n]on ''is'' that the summoned Oracle ''is'' the DM, being deliberately evasive, and successfully so. That would satisfy it being both that which Ponytail seeks, ''and'' the entity of which Ponytail summons in order to seek it! Cueball, however, is currently just seeking food, which (one assumes) the DM-slash-Oracle is not.) [[Special:Contributions/172.68.229.25|172.68.229.25]] 12:48, 6 May 2025 (UTC)

My physics skills are rusty but 20 pounds is much more than the Planck mass. Doesn't this imply that Randall's dark matter particles would be black holes? [[Special:Contributions/172.68.243.107|172.68.243.107]] 10:05, 6 May 2025 (UTC)
:Yes, you are right that 9 kg is about 417,000,000 times more than the Planck mass (21.76 μg), but no, that doesn't imply that 9 kg dark matter particles would be black holes, for that particle can be larger than 417,000,000 Planck lengths (1 Planck length is c. 1.616255×10–35 m, so above 7 rm, this particle would not collapse into a black hole). [[Special:Contributions/172.68.245.81|172.68.245.81]] 10:23, 6 May 2025 (UTC)
Since it's Star Wars day and the 20 lbs. reference would be causing a massively large amount of mass, would it be safe to say that they "sense a great disturbance in the force?"
[[Special:Contributions/67.84.20.42|67.84.20.42]] 10:20, 6 May 2025 (UTC)

Back in 2005, when the kg was an actual object's mass, there was an article about what a five pound (~2.268 kg) electron is, but it was deleted, for it is a "trivial result of special relativity". [[Special:Contributions/172.68.245.81|172.68.245.81]] 10:23, 6 May 2025 (UTC)

Since pounds are a measure of weight, and weight is a measure of the gravitational attraction between an object and its "planet", what is the reference planet that is being used to define the weight of the Dark Matter particle?
 Should we assume that Earth's surface is being used as the reference, even though we have no measurements that suggest DM particles are around us, and no reason to assume that the particles would even notice that Earth has a "surface"?
 If Randall wanted to use mass, then he should have used the imperial unit of slug, but I suppose saying that a DM particle is 0.62162 slugs might not give the readers quite the same impression as using 20 pounds. [[User:Galeindfal|Galeindfal]] ([[User talk:Galeindfal|talk]]) 13:38, 6 May 2025 (UTC)
:I might be missing some humour here, but the pound is actually a measure of mass, just like the gram, so it doesn't vary from a planet to another. You might have fallen prey to the second paragraph of the {{w|pound-force|wikipedia article about the pound-force}}, which states: 'Pound-force should not be confused with pound-mass (lb), often simply called "pound"' [[Special:Contributions/172.71.127.160|172.71.127.160]] 14:35, 6 May 2025 (UTC)

:I don't see anything like the pentagram with candles at its web site. The comic seems more like they're summoning a daemon. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 14:10, 6 May 2025 (UTC)

Any idea where Randall came up with "20 pounds"? Why not 19 or 21 (blackjack!)? Why not use Newtons (too figgy?)? Only thing I can think of is that, in America at least, many people think they are "about 20 pounds overweight." I think that's too much of a stretch (pants???) to be the answer here. [[Special:Contributions/172.68.27.170|172.68.27.170]] 14:07, 6 May 2025 (UTC)
:I think it's just humorous, adding to the imprecision / casualness of "about 20". Imperial measurements feel "less scientific" than metric. [[Special:Contributions/162.158.146.124|162.158.146.124]] 16:26, 6 May 2025 (UTC)
:The amount of people confusing mass and weight/force in this thread is pretty disappointing for an xkcd forum. You can't convert pounds into Newtons. [[Special:Contributions/162.158.172.143|162.158.172.143]] 16:38, 6 May 2025 (UTC)
:The poster meant Kilograms rather than Newtons I assume. Under the assumption that the oracle is satire for large language models and AI chats, the "20 pounds" shows the kind of tone and data the AI has been tuned to provide. It's a way they behave when outside the core domain they are well-trained for, producing a certain brand of mistakes, awkwardnesses, and uncanny valleys, that may be quite humorous when first encountered. [[Special:Contributions/172.70.111.77|172.70.111.77]] 22:33, 6 May 2025 (UTC)
I don't think it's accurate to say (as the explanation does right now) that 20 lbs is too little to detect through gravitational interaction. Throwing some numbers together: a 20lbs-sphere of Osmium, the heaviest stable element, is about 4.5cm in radius. If a 20lbs point mass flies by just above the surface of that sphere, it would generate a gravitational force of about 2.5 micronewtons (hooray for Gauss's theorem). That's the weight of a few grains of salt - small, but definitely detectable. If they're all really really fast, or there's always lots of them around at any given time or something, that might wash out any measurements (someone more knowledgeable about dark matter can probably comment what the expected velocity and flux density of 20lbs-dark-matter-particles would be where we are). But in principle, rather measurable! [[Special:Contributions/162.158.172.142|162.158.172.142]] 17:00, 6 May 2025 (UTC)

"A particle that interacts with nothing except gravity, could only be detected by a gravitational telescope." -- Detected by a whatnow? Is that a thing which exists? Google had nothing for "gravitational telescope" when I searched for it.
Additionally, are there any theoretical physicists out there who can weigh in on how plausible the "20 pound particle that doesn't interact with anything else" theory is? [[User:MeZimm|MeZimm]] ([[User talk:MeZimm|talk]]) 19:33, 6 May 2025 (UTC)
:Well, we haven't seen any such thing. But... that is of course the point. So, by logical extension, it ''must'' be true! :o [[Special:Contributions/172.70.58.130|172.70.58.130]] 21:05, 6 May 2025 (UTC)

There’s a few places online that I’ve seen people ''frustrated'' about dark matter because it’s been so hard to detect, even hoping that it turns out to be experimental error or otherwise not real (for example, [http://www.collectspace.com/ubb/Forum3/HTML/005665.html this collectSPACE thread]) just because it has been so “annoying” to readers of science news to not have a solution for so long. I think this comic could be kind of a joke along those lines (“what if it turns out dark matter ''doesn’t'' matter at all and we’ve been wasting our time?”) but played out in a ridiculous way because dismissing any scientific research, however frustrating, as “a waste of time” would be very un-XKCD.

2641: Mouse Turbines

2022-07-04T22:30:47Z

172.70.230.63:

{{comic
| number = 2641
| date = July 4, 2022
| title = Mouse Turbines
| image = mouse_turbines.png
| titletext = It's sad seeing those videos of turbine blade being torn apart in high winds, but it's the only way they can disperse their seeds.
}}

==Explanation==
{{incomplete|Created by a RENEWABLE ENERGY RODENT - Elaborate on the title text. Do NOT delete this tag too soon.}}

[[Beret Guy]] and [[Megan]] are walking in summer, where Beret Guy expresses his appreciation for typical features of a summer day. He also mentions "wind turbines" put up by field mice, which Megan initially assumes to be referring to dandelions (similar to the wordplay that Beret Guy utilized in [[1322: Winter]]). However, Beret Guy turns out to be speaking literally, as he picks up what is in fact a tiny {{w|wind turbine}} and blows into it. This causes the blades of the turbine to spin very rapidly, generating a lot of power for the structure it is connected to, thus causing a field mouse to cheer in excitement.

The title text claims wind turbines reproduce by dispersing their blades, in the manner of dandelions {{w|seed dispersal}}. Beret Guy might now be mistaking dandelions for additional wind turbines, though he seemed to know there was a difference, and the idea of turbine seeds conflicts with his prior assertion that the wind turbines were built by field mice.

Sadly, the efficiency of wind turbines is proportional to their size,[https://www.energy.gov/eere/articles/wind-turbines-bigger-better] a limitation not shared by other forms of renewable energy such as {{w|solar panel}}s and {{w|pico hydro}}. According to [https://www.omnicalculator.com/ecology/wind-turbine this calculator], a 10 centimeter radius wind turbine powered by a 5.7 meter/second breath[https://www.sciencedirect.com/science/article/pii/S2215098616300830] would produce one watt at just 26% efficiency.

Further frustrating mice use of wind power, {{w|Wind gradient|windspeed increases logarithmically with height}} above ground. Windspeed is reported as its value 10 meters above ground, where it is 1.5 times faster than at ground level.[https://www.nooutage.com/wind.htm] In the U.S., where Randall lives, average year-round windspeed is about 15 km/h,[https://sciencing.com/average-daily-wind-speed-24011.html] or about 2.8 m/s at ground level, yielding only 0.1 watt for such turbines. However, a typical mouse weighs 25 grams,[https://web.jhu.edu/animalcare/procedures/mouse.html] compared to about 81 kilograms for humans in the U.S.,[https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3408371/] so presumably mice electricity needs would be about 0.03% of people. The average U.S. residential customer uses about 1,242 watts of electricity,[https://www.electricchoice.com/blog/electricity-on-average-do-homes/] 0.03% of which is 0.37 watts. Therefore, three such turbines could be able to serve about four fifths of one mouse's needs, not counting their {{w|home energy storage}} battery efficiency overhead.

2639: Periodic Table Changes

2022-07-01T02:40:32Z

172.70.230.63: /* Explanation */

{{comic
| number = 2639
| date = June 29, 2022
| title = Periodic Table Changes
| image = periodic_table_changes.png
| titletext = It's nice how the end of the periodic table is flush with the edge these days, so I think we should agree no one should find any new elements after #118 unless they discover a whole row at once.
}}

==Explanation==
{{incomplete|Created by a SPITE ELEMENT - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

The {{w|periodic table}} is a table used to arrange {{w|chemical elements}} according to their chemical and physical properties. This comic proposes "changes" to the periodic table that would be more pleasant aesthetically or make the periodic table look more regular. Some of these are (somewhat) practical changes to element abbreviations that could improve clarity in English, though changing documents to use different abbreviations would probably be more trouble than it's worth. However, other changes move elements around without taking into account that elements would stop being arranged by their properties. The periodic table would stop being useful after such changes unless said changes were meant to physically change the material properties of the elements, which would be impossible{{citation needed}}, although the comic plans to solve the problem with "free training" to their atomic behavior. The attitude is similar to impossible economic plans attempted with unpleasant results, possibly a current event.

Other modifications make up new elements or remove existing ones from the table, which would not be a reasonable decision given that the periodic table is supposed to include all existing elements, whether they make the table neater or they don't.

;Move helium over here. It fits nicely!
Helium is moved from the upper right corner to the second column next to hydrogen. However, the reason it is placed at the far-right Group 18 and not Group 2 is because it is a {{w|noble gas}}, rather than a reactive {{w|alkaline earth metal}}. You could say helium is in group 2 because it has two electrons in its outer shell, but normal periodic tables place it in group 18, the noble gases, with which it has far more in common. Hydrogen has similar problems being in group 1, as it's a non-metal and the elements below it are metals which don't have much in common with it chemically. There are periodic tables that show hydrogen floating above the periodic table for that reason.

Group 18 was not known at the time of the original table, which used I-VII (1-7) for the otherwise full-height columns, which turns out to reflect the number of free ('valence') electrons in their outer 'orbit', in one useful understanding of the atomic model. When added, the new final column was called either VIII (having a full outer shell) or Group 0 (having none free) and placed to the right of VII. It was thought that these Noble gases were thought to be unable to react with other elements, but xenon compounds were discovered in 1962, and many others have been discovered since then, that are formed by a process not as trivial as being spare-valences of one element 'keying' into valence-gaps of another.

From the fourth row downwards the inserted block of Transition Metals represent a larger electron shell with more positions for free electrons and those elements to the right would have more electrons than those above them, by this measure, but their physical properties are still best dictated and aligned by the complement to the valence (i.e. the gap-size). The current numbering system shows the outer-shell electrons accurately in the rows where the ten new columns are, but the upper rows of columns 13-18 have ten more (or sixteen more, for Helium) than is the case. Similarly, once lanthanides and actinides are considered, the group number and outer-shell count becomes disconnected again in the opposite way. But it still seems useful enough to currently label in this manner under current {{w|IUPAC}} guidance.

;Elements in this corner are cool. Add more!
TBD (to be determined). Elements in that corner, such as carbon, oxygen, phosphorous, and nitrogen, participate in covalent bonding and are the primary elements involved in biochemical reactions, which may be why they are considered cooler than other elements.

;Sp (Spite element)
Wedged between fluorine and neon. This is a reference to spite houses, houses jammed into a narrow space to block other construction, or spite fences, which are fences built to annoy neighbors.

;Merge these boring metals with titanium to make *tixanium*
Tixanium (Tx) replaces five metals, including titanium (Ti). This may be a reference to the term "UX" (user experience) being used instead of "UI" (user interface) as more of an umbrella term.

While titanium certainly has an impressive name, and is used in the aerospace industry and other high-performance applications, the others are hardly boring; manganese, for example, was part of the cover story for the top-secret {{w|Project Azorian}}.

;Update Latin/Neo-Latin symbols to match names. This isn't ancient Rome.
* Sodium: Na (Natrium) => So
* Potassium: K (Kalium) => Pm
* Iron: Fe (Ferrum) => I
* Silver: Ag (Argentum) => Sv
* Gold: Au (Aurum) => Gd
* Tin: Sn (Stannum) => Tn
* Lead: Pb (Plumbum) => Ld
Since I is already used for Iodine, it gets a new abbreviation Io, and Gadolinium is re-abbreviated to Gm to free up Gd.

Note that most of these changes will actually make the table less readable if one considers languages other than English. For example, in european languages, 'I' for iron will work for Irish and Dutch, while 'Fe' currently matches in French, Italian, Portuguese, and most of the languages in Spain.

This group of changes doesn't include antimony (Sb -- stibium), but that’s because it gets replaced by “carbon III” (see below).

;Replace the blander post-transition metals with new kinds of carbon
* Indium (In) -> C II.
* Antimony (Sb) -> C III.
* Tellurium (Te) -> C IV.
* Thallium (Tl) -> C V.
* Bismuth (Bi) -> C VI.

Carbon can make four covalent bonds, which means it can form a huge range of chemicals, above all ones vital to life. The post-transition metals don't have this level of interest. If there were more chemicals like carbon, it could allow more exciting chemistry and perhaps new kinds of life.

;That W annoys me
* Tungsten: W (Wolfram) -> Tg.

Another element whose symbol doesn't match its English name. "Wolfram" is the name for tungsten in some languages and is derived from the mineral wolframite, which comes from the name "wolf rahm" in German (wolf soot).

Oddly, despite changing Latin and German abbreviations to English, Randall does not change the symbol for mercury (Hg from the Greek "hydrargyrum").

;3.4% of all elements are named after Ytterby, Sweden (pop. 3,000). Let's keep Yttrium, but rename the other 3 after bigger cities (Tokyium, Delhium, and Jakartium?) to be more fair.
Four elements -- yttrium (Y), ytterbium (Yb), terbium (Tb) and erbium (Er) -- are named after {{w|Ytterby}}, a Swedish village where they were discovered. Scandium (Sc), thulium (Tm), holmium (Ho) and gadolinium (Gd) were isolated from minerals found in the same quarry. Randall suggests naming 3 of them after some other major world cities, despite those cities having no connection to those elements.
* Terbium (Tb) -> Tokyium (Ty) - Tokyo
* Erbium (Er) -> Delhium (Dh) - Delhi
* Ytterbium (Yb) -> Jakartium (Jk) - Jakarta
Randal may be using using 2010 census data (2946); Ytterby mine is located on the island of Resarö, found under 0187TB103 in table [https://www.scb.se/en/finding-statistics/statistics-by-subject-area/environment/land-use/localities-and-urban-areas/pong/tables-and-graphs/localities-2020-population-land-area-population-density-per-locality/ MI0810], population 3212 (2020 census).

Interestingly, [https://en.wikipedia.org/wiki/Isaac_Asimov Isaac Asimov] made essentially the same remark in his science essay ''The Multiplying Elements'', saying that it was a waste of element names that could have been used to honor great contributors to chemistry. One obvious candidate would be [https://en.wikipedia.org/wiki/Henry_Moseley Henry Moseley] (mentioned in another of Asimov's essays, ''The Nobel Prize That Wasn't'') who used early X-ray spectroscopy to resolve the confusion over rare earth elements, finally put the Periodic Table on a firm ground and conceived the idea of "Atomic Number".

;Inserting the lanthanides and actinides properly makes the table too wide. Triage is needed. Each element will be offered free training to help adjust to its new column.
Though the lanthanides and actinides typically are placed underneath the bottom of the table, they actually belong in the 6th and 7th rows of the table between the 2nd and 3rd columns, as they are numbered elements 57-70 and 89-102. This section of the table is typically excised to give the overall shape more appealing dimensions; including this section in the main table [https://sciencenotes.org/wp-content/uploads/2017/01/PeriodicTableExtended.png extends the length dramatically]. This proves rather unwieldy especially when referencing the table for the lower-numbered elements, which are generally more common, and/or elements far to the sides of the table, which are often more influential in chemical reactions. Randall recommends that a subset of these elements be placed in a new row at the bottom of the table (making them elements 93-110) and they will receive "training" to adjust to their new columns.

The title text suggests discovering elements only in entire rows at once. Elements with more protons than 118 could be discovered in future by collisions in particle accelerators, but aren't likely to be discovered in an entire row at a time.

Changing the periodic table was also the topic of [[2214: Chemistry Nobel]], and the red-ink style of "aesthetic" revision over a complex and established diagram is highly reminiscent of [[1902: State Borders]].

:Changes I would make to the periodic table
:[A modified periodic table is shown, with changes in red.]

:[Helium is moved from the upper right corner to the second column next to hydrogen.]
:Move helium over here. It fits nicely!
:[Two elements labeled TBD are added to the left of boron and aluminium.]
:Elements in this corner are cool. Add more!
:[A narrow triangular shape is wedged between fluorine and neon.]
:Sp (Spite element)
:[Tx replaces five elements: scandium, titanium, vanadium, chromium and manganese.]
:Merge these boring metals with titanium to make *tixanium*
:[The symbols of sodium, potassium, iron, silver, gold, tin and lead are changed to use letters from their English names.]
:Update Latin/Neo-Latin symbols to match names. This isn't ancient Rome.
:[The symbols of indium, antimony, tellurium, thallium and bismuth are changed to symbols containing the letter C followed by Roman numerals II to VI, respectively.]
:Replace the blander post-transition metals with new kinds of carbon
:[The symbol of tungsten is changed from W to Tg.]
:That W annoys me
:[Neodymium is highlighted.]
:Neodymium can stay—magnets are cool
:[A subset of lanthanides and actinides are to be placed under the bottom of the main table into a single row.]
:Move
:Inserting the lanthanides and actinides properly makes the table too wide. Triage is needed. Each element will be offered free training to help adjust to its new column.
:[The symbols of terbium, erbium and ytterbium are changed to Ty, Dh and Jk, respectively.]
:3.4% of all elements are named after Ytterby, Sweden (pop. 3,000). Let's keep yttrium, but rename the other 3 after bigger cities (tokyium, delhium, and jakartium?) to be more fair.

Talk:1761: Blame

2022-06-29T17:00:01Z

172.70.230.63: removed the word "quite"

This comic is one of Randal's best EVER! It is a scathing and biting commentary on the current angst of a huge swath of liberal and progressive snowflakes.

The first panel sets the stage with a subtle but jarring inversion of the normal human response "bad thing happened >>> I feel sad" to the much more autocentric "I feel sad >>> bad things are happening" Worth a derisive snort in its own right, we can accept this little lapse since we are deluged with so many examples of such self interest from every direction today. Ignoring the little deviation ( never something one should do with xkcd) we accept the lead-in panel as simply saying "bad things are happening"

The second panel is a riff on the "something bad happened therefore someone is to blame" meme of modern Western society - examples such as blame the coffee supplier if one scalds oneself spilling hot coffee, blame the company that grinds up and sells powdered rock for any perceived negative effects of assiduously dusting said powdered rock over ever body orifice and breathing it for thirty years. This is a masterful set up! We now know where the joke is going! Cueball is going to come up with an absurd and funny scapegoat for the bad things happening in panel one! We are ready for the punchline....

But the punchline is not that at all! It is exquisite! The blame is on Cueball's Facebook friends! We hang in the moment of disbelief where our world view must be reset! Then it hits! We realize the the blame is not for "bad things happening" at all - we have been set up, had! The blame is for Cue ball's "Feeling sad"! It is not for all the harm, blood, guts, and gore that are really happening in the world but for the fact that something - his Facebook friends specifically, have caused him to think about these bad things, penetrating his safe bubble and making him sad.

That the "bad things" are more than likely simply the shocked and hurt feelings of Cueball's friends as a result of the recent 2016 election only heightens the joke. No real human suffering is usually openly discussed in the shallows of Facebook. We realize this and the satire is complete.

The mouse over text emphasizes the break from real issues to the relatively shallow feelings (being "scared") and even more shallow and petty response (yelling at them). [[Special:Contributions/108.162.242.118|108.162.242.118]] 19:42, 20 November 2016 (UTC)

You seem to lack the skill of introspection. It's not the "inversion of normal response" (bad things are happening because I feel sad), it's an observation that I feel sad and the investigation into why that is. [I feel sad. (Why is that?) Bad things are happening. (Why are they?) They must be someone's fault. But whose?] The punchline is that Cueball's conclusion that his Facebook friends are to blame indicates the state of intense frenzy on the site. [[Special:Contributions/172.68.46.18|172.68.46.18]] 18:43, 10 December 2016 (UTC)

It seems like he's talking about all of the bad things that have happened in 2016 so far making fun of Facebook posts that blame everyone for the things that are happening

: In particular the recent election[[Special:Contributions/108.162.215.224|108.162.215.224]] 08:16, 18 November 2016 (UTC)
Is this a reference to the "echo chamber" issue raised in recent US election? I.e. blaming my friends on facebook for only sharing stories that reinforce my biases and thus my failure to be fully informed about why people who disagree with me do disagree and only blaming them for being dumb isn't a failing on *my* part, but on my friends' parts for only sharing echo-chamber-y material. [[Special:Contributions/108.162.237.87|108.162.237.87]] 10:03, 18 November 2016 (UTC)

I definitely think it's worth mentioning that this comic is, while written to be timeless, clearly a reaction to the election. (Randall has endorsed both Obama in 2008 and Clinton this year, and judging by #500, cares more than a little, so it's hard to conceive that this *wouldn't* be about the election.)

There are two types of Facebook activity that may be the target of this satire: 1) engaging in angry arguments with Facebook friends with *differing* political opinions, and 2) making numerous angry posts and comments against the other side, despite the fact that they’ll mainly be seen by *like-minded* people in your social media echo chamber. I expect that this comic is aimed at both: 1) the futility of internet arguments has been a topic before, while 2) the title text specifying “scared friends” clearly indicates like-minded people.

: Just added the "friends who disagree" to it.
By focusing on blame he has cleverly shifted thinking to Q:"are your friends on Facebook to blame?" A:"probably not as they are almost all likely to have similar views to you" Q:"So why vent anger on Facebook to people who aren't to blame and you don't want to change?" A:"errrrrr...." {{unsigned ip|141.101.98.224}}

Couldn't it just be that it is usual for politicians to blame "the others" (countries, etc) to justify that things are not all good in the country, and then, proceed to threaten to do bad things (go to war, revoke treaties, etc) to appease the "country's inner sadness" (and, through this, get votes) ? [[Special:Contributions/173.245.48.61|173.245.48.61]] 14:53, 18 November 2016 (UTC)

My inclination was to take this as satirizing the number of people who have taken to Facebook to rant about an event that was clearly not the fault of one's immediate circle. However one feels about the election it's clear that spewing venom at anyone who happens to be in your Facebook list is unproductive at best and certainly isn't addressing any appreciable portion of the cause of these events. It seemed to be supported by taking the hover text as a continuation of the problem, suggesting that Cueball has devolved to seeking catharsis.

:Agreed, I took this comic to be a satirical attack on people who post all caps angry messages on Facebook. EX: "I can't believe all you people did this!" , when 90% of their friends probably agree with them (See "Echo Chambers" comments)- it's almost certainly in context of the election, as "Scared Friends" represents a great many Clinton voters very well right now. The clear interpretation to me is that people posting these angry Facebook rants are not going through normal, well-thought out processes.[[Special:Contributions/108.162.219.111|108.162.219.111]] 23:11, 18 November 2016 (UTC)

This explanation currently claims venting can reduce stress. I have heard that venting actually makes you angrier. (First Google hit appears to be a scientific paper: https://www.mtholyoke.edu/courses/jbickfor/bushman2002.pdf ).

The reference to yelling is obviously sarcasm. Nobody would really suggest the absurd idea that Randall really thinks yelling at friends is acceptable, so really what is being highlighted is that yelling at friends is NOT a good idea. The explanation text should not suggest that the idea is anything other than absurd. --[[User:Rotan|Rotan]] ([[User talk:Rotan|talk]]) 00:15, 19 November 2016 (UTC)

This could be a critique of the specific social media. The true meaning being expressed by what is not included: "My Friends on Facebook" as compared with all the other areas in which one would have friends, e.g. "My Friends at the Coffee Shop" or "My Friends at Work". It could also be intended for the reader to infer through abductive reasoning that the algorithms (user interface) of which facebook is composed may promote this type of behavior. {{unsigned ip|108.162.246.32}}[[Special:Contributions/108.162.246.32|108.162.246.32]] 02:14, 21 November 2016 (UTC)

Why Facebook: http://arstechnica.com/staff/2016/11/its-time-to-get-rid-of-the-facebook-news-feed-because-its-not-news/ --[[User:JakubNarebski|JakubNarebski]] ([[User talk:JakubNarebski|talk]]) 12:35, 19 November 2016 (UTC)

I think Randall is trying to address all the Clinton supporters who said to their longtime social media friends, "If you voted for Trump, you're a sexist, racist piece of ****, and you should get out of my life forever," and other similar things, because there were a LOT of those people on social media, despite every liberal icon from Michael Moore to Bill Maher telling people to protest and to fight much harder than usual, but also respect the political process (IE, don't riot if there's no last minute electoral college switch). When Obama was in the White House, the the far-right Republicans did awful things governed by fear. Now with Trump, I hope the far-left Democrats don't do anything crazy ALSO governed by fear, because that will just lead to more white people becoming Republicans because they felt unwelcome by the Democrats. Just my opinion. [[Special:Contributions/108.162.210.252|108.162.210.252]] 19:27, 19 November 2016 (UTC)

It occurs to me that the joke is simply about relative perception. Before facebook the media was the primary source for most people to make political decisions. I have heard it repeated by the media that Trump "used" social media to influence voters. Ergo, similar to that of the gun argument "if guns did not exist, there would be less violent crime" I feel that Randall is making a simile by saying "if facebook did not exist, Trump would not have been elected" and, by extension, we would not know as much about the magnitude of bad happenings in the world. Therefore, the first contact cause of Randall's sadness both before and after the election is Facebook. However, there's a reason he chose to blame facebook users and not just facebook. If facebook users were more like him and generally promoted positive aspects of the world (or at least be more balanced), he theorises that everyone (including Randall) would be more likely to be upbeat and positive. This, of course presumes a number of things, the simplest of which is that the world would be better if things went the way Cueball wanted them to. [[Special:Contributions/162.158.178.104|162.158.178.104]]

So uhm, did whoever wrote the above explanation not understand the concept of sarcasm? Because this comic comes off as 100% sarcastic to me, and yet it's taking it very seriously. [[Special:Contributions/172.68.78.127|172.68.78.127]] 09:51, 20 November 2016 (UTC)

It's simple what it means, I'm not sure why people aren't getting it. Randall is trying to bring balance as currently everyone is lashing out against their own friends on facebook as a result of the anger of Hillary losing. He's being sarcastic to highlight the absurdity of the thought process that people blame their friends for the "bad things happening". I was quite peeved that he got political, but this comic undid a lot of my peevedness. I'm not sure who wrote the page here, but they clearly have no clue what this comic is about? --[[User:Drkaii|Drkaii]] ([[User talk:Drkaii|talk]]) 00:08, 29 November 2016 (UTC)

It is a bit odd that everyone thinks Randall went political and this is all about the election. I wonder how many more panels will be interpreted in this light before the wounds heal and people get back to work making their life and country work. {{unsigned ip|108.162.241.106}}

Explain XKCD's talk pages are an art form all their own. Whether Randall is commenting on the election in the comic or not (he probably is), this talk page managed to exactly recreate, like a time capsule, the frenzied insanity of the post-2016 election internet, on which the comic itself is (probably) commenting. The talk page on the comic with the actual endorsement is plenty dramatic, but this one is all the DNA of that week's petty insanity preserved in amber while discussing a comic discussing that week's petty insanity.

562: Parking

2022-06-29T13:28:18Z

172.70.230.63: /* cheerful people are not afraid. Them being afraid of black hat does not make sense here */

{{comic
| number = 562
| date = March 30, 2009
| title = Parking
| image = parking.png
| titletext = Police reported three dozen cheerful bystanders, yet no one claims to have seen who did it.
}}

==Explanation==
There are few things so annoying as finding, when a parking lot is full, that someone has parked so carelessly as to take up two spaces. Even worse, it may have been intentional; they decided to exchange the risk of someone accidentally scratching their car for the risk of someone doing it on purpose, see [[1030: Keyed]]. However, there are also non-violent ways to tackle the problem; [http://www.threadless.com/product/187/I_Park_Like_an_Idiot politely leave a note], or (if possible) just move their car (whether to its proper alignment or to an impound lot).

Of course, [[Black Hat]] takes the less-traveled path, apparently involving a {{w|cutting torch}} and what looks to be a {{w|circular saw}}. The offending portion of the parked car is sliced off (entirely without surgical precision) and neatly slotted into the remainder of the space. It is now legally parked, but will never become a functional car again. But at least Black Hat finally has space for his own car!

This comic may be the one referenced in [[496: Secretary: Part 3]], where it is shown that Black Hat '...completely disassembled a car' because 'It was parked across two spaces! It was only fair', or this is the second time that a car has been in the way of him parking, so he has taken matters into his own hands.

The title text indicates that a large crowd watched Black Hat at work but refused to identify him, presumably because they feel that the car owner got what he deserved.

==Transcript==
:[Black Hat is in a car driving around a parking lot.]

:[Black Hat's car pulls up next to a red car, that's parked over a line at an angle that block two spaces.]

:[Black Hat gets out of his car.]
:''SLAM''

:[Black Hat is now holding a blow torch and a rotary saw, He's also wearing goggles and fuel tanks on his back. The blow torch is lit.]
:''Fwoosh''

:[The badly parked car has been cut in half along a diagonal, and the half of the car that was in the second slot has been moved into the same slot as the rest of the car. Black Hat's car occupies the newly freed space.]

==Trivia==
Black Hat, in the fourth panel, is also seen in the "Your Ad Here" screen.

The title text refers to the recursive time period on Sep 12. If you don't stop when you reach N=0 bottles, the repetition never ends, so that time interval beecomes infinite.

The difference is that the Beer song has a natural stopping point at 0, while ''The Song That Never Ends'' is completely repetitive.

Talk:2634: Red Line Through HTTPS

2022-06-21T02:10:58Z

172.70.230.63:

HTTPS was standardized in 2000 or so, so 2015 is quite a stretch for a site to not use it because the site was last updated before HTTPS was widely available.
With pretty much any browser now, a red line through HTTPS means that the site _is using HTTPS_, but it is _not trusted by the browser_ (due to e.g. the certificate being self-signed or expired).
[[User:Darrylnoakes|Darrylnoakes]] ([[User talk:Darrylnoakes|talk]]) 04:28, 18 June 2022 (UTC)

:I think the intended joke is that the site's certificate expired in 2015, instead of the site is not using HTTPS. [[Special:Contributions/108.162.221.101|108.162.221.101]] 06:29, 18 June 2022 (UTC)

:2015 is when the first Let's Encrypt certs were issued, and 2016 is when LE became generally available to the public and thus when free SSL/TLS became very very easy for just about anyone setting up a web server, hence the comic citing 2015. However even with a valid cert you might have a number of issues, like [https://www.mixedcontentexamples.com/ mixed content]. At least in Firefox, an expired cert gives a big warning screen that gives you an option to add a security exception; I don't care enough to install Chrom{e,ium} to test its UI. [[Special:Contributions/172.69.69.250|172.69.69.250]] 08:30, 18 June 2022 (UTC)

::Chrome has this warning screen including an option to bypass the warning as well. I believe all browsers do. I think the only exception to this is when a site has strict transport security enabled. [[User:Jespertheend|Jespertheend]] ([[User talk:Jespertheend|talk]]) 10:49, 18 June 2022 (UTC)

:::Until about 2015 no-one complained if you didn't offer HTTPS as long as you didn't request anyone's credit card number or offered .exe files: An internet site offers nothing but inherently untrustable text. It might contain ads that can execute any piece of javascript. It even could contain flash - so why pay a substantial amount of money to make the transport of that data more secure? Nowadays most web browsers tell on you if you don't secure connections and allowing the telco to see what data you download from where is felt as a privacy intrusion. On the other side not every hoster offers https for multiple domains...--[[User:Gunterkoenigsmann|Gunterkoenigsmann]] ([[User talk:Gunterkoenigsmann|talk]]) 15:03, 19 June 2022 (UTC)
: 2015 is around when global information security and true news radically reduced. [[Special:Contributions/172.70.230.63|172.70.230.63]] 02:10, 21 June 2022 (UTC)

Not sure it's true that if there is a problem with HTTPS like an expired cert that the connection is made with HTTP instead. [[Special:Contributions/172.69.79.201|172.69.79.201]] 10:11, 18 June 2022 (UTC)

:It's not, it still uses the https connection. It only indicates that the connection might not be secure anymore and anyone could be listening in at that point. [[User:Jespertheend|Jespertheend]] ([[User talk:Jespertheend|talk]]) 10:49, 18 June 2022 (UTC)

I actually am bemused by this. Not sure if I only visit the wrong (or right?) websites with the wrong (or right?) browsers, but I don't recall ever notably having seen struck-red links. (Perhaps I have, and assumed it was a site informing me that they were dead links, not now followable?) I ''do'' occasionally follow a normal-looking link (maybe locally CSSed in a over-riding manner of format?) and I get the browser load up a whole-screen "Problem with certificate (Are you sure? Jump through hoops for me to progress.)" which I may then take under considered advisement but mostly has me checking I'm not being spoofed as to the destination or something. Is this where the red strikethrough appears for others?
 I also have at least one site that is steadfastly still HTTP-only, and neither I nor my various browsers have any problem with it as I know what I'm doing, whilst the browsers just go there without particular complaint or anything more than usual addressbar clues... I might have "added to exception from warning" once or twice in the distant past, but not in every case. So I'm learning something here, but I don't know what. Sounds like something Edge would do, but I don't use Edge... I'm generally on Chrome, Firefox and a handful of 'lesser' flavours, all definitely updated. [[Special:Contributions/172.70.90.173|172.70.90.173]] 11:21, 18 June 2022 (UTC)

:You can find some examples of the red line on https://badssl.com/, but pretty much in all cases you get a full page warning first that something is amiss. You can also try out the http connection at http://http.badssl.com/, http connections are a bit more complicated. Some browsers don't show a warning at all, while others only show a gray 'insecure' label in front of the url. And as can be seen here [https://blog.chromium.org/2017/04/next-steps-toward-more-connection.html], the plan is to eventually show similar warnings for HTTP sites as what is currently shown for HTTPS sites with a failed certificate. [[User:Jespertheend|Jespertheend]] ([[User talk:Jespertheend|talk]]) 11:32, 18 June 2022 (UTC)
::Ugh, I'd hate that. I have a little webpage of my own, and I'm not in a position to be able to go https, :( That "badssl" site has several example issues, which ones go red/strikethrough? I want to confirm no browser I have does that. [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 04:56, 19 June 2022 (UTC)

:I was about to remark the same thing, :) NEVER seen a strikethrough. I'm rather assuming it's something Chrome does, because I about exclusively use Firefox, and Chrome likes to be weird and non-standard (main reason I generally don't use it), and too many people act like there's no other browser than Chrome. Likewise, most I get is "Security Risk!", then find out it's a Bad Certificate, then it turns out it expired and they just haven't updated it yet. Stop being so dramatic, LOL! [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 04:28, 19 June 2022 (UTC)
::I'm a Chrome user (part of the time, being the "handful of lesser flavours" contributor, above, but using it this very second) and I don't see it. But then I turned off its look-ahead (downloading of pages it thinks I'll go to next) because I'd rather it not, and as some sort of pre-emptiveness seems necessary to know a link ''should'' be red-struckthrough, I probably (hopefully?) neutered that stupid potential exploit too... So don't take my experience as gospel. (But still sounds like an Edge thing, to me, the way that's the new IE in the current browser ecosystem.) [[Special:Contributions/172.70.162.5|172.70.162.5]] 11:32, 19 June 2022 (UTC)
:::It's not links (to other pages) that get the strikethrough. It's the protocol/scheme name in the current page's address bar. See, for example, the picture in https://superuser.com/a/369839/93954. This is far less intrusive than any of the warning pages you've mentioned seeing; maybe you just haven't noticed when it does that? For a current live example, in Edge, I'm seeing the (not red) strikethrough e. g. on https://self-signed.badssl.com/ both on the warning page and after clicking through it to accept the bad certificate. And as it happens, I could swear that just within the last few days I've been on a mixed-content website that displayed the strikethrough, but I'm not certain what website it was and I can't reproduce this now, so I'm probably misremembering. [[User:Chortos-2|Chortos-2]] ([[User talk:Chortos-2|talk]]) 23:44, 20 June 2022 (UTC)

I've made a rather large change to the page to better explain the meaning of a red line through https. I removed any mentioning of using the HTTP protocol as that is incorrect. If a browser uses the HTTP protocol it is shown in the url using 'http://'. Since the comic was talking about a red line through 'https' I'm assuming the usage of the HTTP protocol is unrelated here.
Though it's possible I removed some more information from the page that might still be desired. Such as the mentioning of AI-generated spam sites and man in the middle attacks. These seemed redundant to me for explaining the joke.
I also put some more emphasis on the red line usually meaning that something bad is going on. Browser venders put a lot of effort in security, and having everyone think that a red line is not that big of a problem is the last thing they'd want. [[User:Jespertheend|Jespertheend]] ([[User talk:Jespertheend|talk]]) 11:23, 18 June 2022 (UTC)

While it's true that some browser security warnings are false alarms, I think that paragraph is missing the point of the comic. Cueball is assuming that any site that's been around for years must be operated well. But often the maintainers of the site get complacent and don't update to newer standards. And even if the real site is legit, the security warning can mean that traffic has been intercepted, so you're not actually going to the real site. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 13:40, 18 June 2022 (UTC)
: Also, someone who hasn't taken the trouble to keep their security certificates up to date is probably more likely to have neglected their server security generally, so it's more likely that someone could have hacked them and be serving you up all kinds of crap. [[Special:Contributions/172.70.85.177|172.70.85.177]] 08:22, 20 June 2022 (UTC)

I presumed this was about using outdated protocols like TLS 1.0 or weak ciphers. [[Special:Contributions/172.70.110.121|172.70.110.121]] 00:28, 19 June 2022 (UTC)

You'd almost think Randall didn't live in the Boston metropolitan area. I was disappointed. [[User:JohnHawkinson|JohnHawkinson]] ([[User talk:JohnHawkinson|talk]]) 04:30, 19 June 2022 (UTC)

Okay, at least two of us don't see this behaviour, so this is NOT as universal as Randall seems to think, could somebody figure out why and put it in the explanation? (I reject the possibility that we just haven't visited the right (wrong) sites. I, for one, go to WAY too many sites, LOL!). My leading theory is that instead of being universal, this behaviour is actually unique to Chrome (as I don't use it much and can easily have never visited an insecure website on it), since I use Firefox primarily, and many people seem to forget that there are other browsers than Chrome, and Google goes out of it's way to be as weird as possible, including being fancy for the sake of fancy (like the colour-coding and strikethrough). [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 04:49, 19 June 2022 (UTC)

Where is Cueball saying that websites with a red line through HTTPS are more secure than modern websites? In the comic he merely says that the red line means that the website is legit, he doesn't make any comparison at all. [[User:Kzkzb|Kzkzb]] ([[User talk:Kzkzb|talk]]) 22:12, 19 June 2022 (UTC)

I think the current explanation is missing a key aspect of the humor. The fact is, it takes minutes to add HTTPS to your site for free (see e.g., https://www.freecodecamp.org/news/free-https-c051ca570324/). A phisher could set up a site with https and have it trick you into giving up your info for a while before being caught and brought down. I think the outdated-ness of the red line through the https indicates that the site has been around for a long time, and therefore is less likely to be a scam. I'll add something small to this effect, but let me know if you disagree, I'm not 100% sure about this. [[User:Jrfarah|Jrfarah]] ([[User talk:Jrfarah|talk]]) 23:04, 19 June 2022 (UTC)

:While you can set up HTTPS certificate for free in minutes, you need to have control over the domain to be able to. This is key aspect in the security - only I can control my domain, therefore if you see green HTTPS on my website, you can be sure it is a genuine one, whereas if you see anything else, it might not be [[Special:Contributions/89.177.163.36|89.177.163.36]] 16:43, 20 June 2022 (UTC)
::Aside from the issue of a previously controlled+certificated domain being hijacked... As far as I'm concerned a <code>style="text-color: green"</code> sort of thing would suffice to produce the exact same effect.
::Nobody has yet satisfactorily explained ''which'' browsers do this, and under ''which'' circumstances... No Chrome doesn't do this. (Not my Chrome, anyway, but maybe I'm just using the wrong one?)
::But, for when it ''does'' happen, does it not override inline/CSS styles, in which case the link 'warning' is entirely disguisable by the link-author. Even in the most incapable and hobbled version of newb-servicing CMS, and definitely with direct markup-editing capability.
::Or they do, in which case (not that I have much sympathy for the absolutist type) I hear the wailings of a thousand web-designers, unable to control every last visual element to their utter and complete desire because the browser spoils their desired pallette, even if they overlook the mythical strikethrough rendering.
::(The amateur web designer I knew who set up a pixel-perfect site by making the page he desired an ''image'' with ''image-mapped'' hotspot-links on the blue-underlined fully rasterised words... It sounds like he would have neutered the HTTPS warning. But in the most annoying and frustrating way.)
:: I assume it's a common sight for Randall, to have inspired him so (and write about it as if we should similarly have a good idea about it). For me, though, I assumed it was a broken-link thing, i.e. a non-available web resource, but then of course a page/site that is entirely offline cannot be so easily hacked. But I take it on trust that the current explanation (as far as it goes) is the real one. [[Special:Contributions/172.70.91.58|172.70.91.58]] 22:37, 20 June 2022 (UTC)
::: No, this isn't rendered on the page. Go to https://badssl.com/ yourself and you'll see you can't use CSS to change how the https is rendered red with strikethrough in the address bar. But I see Chrome use the red strikethrough display while Firefox doesn't, instead showing "Not Secure" next to the security icon.

Removed unnecessary line. The NSA is mentioned absolutely nowhere in the comic, nor any other intelligence agency, and it comes off as nothing more than an unnecessary conspiracy theory.

What if Randall decides to delve into the mysteries of the unlocked padlock? WE NEED A CONTINGENCY PLAN! [[Special:Contributions/172.68.133.65|172.68.133.65]] 01:27, 21 June 2022 (UTC)

}}

==Explanation==
{{incomplete|Created by A HUMAN! (AGAIN) - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
This comic is a joke about {{w|Helpline|helplines}}, and how people sometimes call helplines for non-significant reason.

The comic starts with someone having called the "Astronomer hotline", hence the title. Judging by the way the helpline employee, [[Cueball]], starts the call, by asking for a description of the weird lights, it is implied that this is the main/only purpose of the helpline.

The caller is in panic, and don't know how to describe the light. But Cueball is used to this and asks the caller to stay calm. And then goes through his check list, asking them if it is day time. Because then he would assume they have just noticed the Sun. This could be seemed very condescending, but it is like when the employee at a tech support hot-line asks if the computer is turned on, or if the caller tried to restart the computer, see [[806: Tech Support]].

The caller is not affronted, but tells that the Sun set, and when Cueball asks if they are stars, and thus stationary, the caller says they are zipping around in the bushes.

At this point Cueball realizes that the the caller just have seen {{w|Fireflies}}. He describes them for the caller as lightning bugs, tree blinkers or ground stars, and tell the caller he is fine, so the caller is now relived.

However, Cueball must admit that astronomers do not know much about fireflies, since they are too fast for the astronomers' telescopes (in general, astronomers don't study terrestrial phenomena {{citation needed}}). And he thus transfers the caller to the "Weird Bug Hotline."

Before the call ends, at Cueball's end, he hears the first question from the new hotline: Is it currently biting you.
Again going directly to the most important part, is there any immediate danger...

Some people (Often {{w|Unidentified flying object|UFO}} enthusiasts) tend to get a little over-excited about calling every light in the sky they don't expect a UFO. This comic takes this to the extreme, where someone calls a helpline because they saw fireflies, and thought they were UFOs. While UFOs are not mentioned by name, they are heavily implied.

The title text is a reference to bugs that have several years between emerging from their larva state. Most famously are the {{w|Periodical cicadas}}, 13- and 17-year cicadas, that only emerge every 13 or 17 years depending on species. The 17 years in the title text, thus refers to the 17-year cicadas. Every 17 years the bug hotline hires a bunch of temporary staff. Either because there will be more callers due to the unexpected new bug, no one has seen for 17 years, (or it could be because they just like to emulate nature and thus do this every 17 years). However, not all broods emerge in the same year. Extra staff is likely only hired for the emergence of the largest brood, Brood X, which last occurred in 2021.

The joke in the title text is that the employment statistics for the weird hotline have to correct for this fact.

172.70.230.63: /* Mierda */

Hi Davidy22,

Just a quick thanks for helping roll back so much of the vandalism. Per your recent log comment, yes, there has been a recent spate of vandalism; before yesterday, it was the odd spammer that I've had to remove. But with the advent of ''Click and Drag'', there's also been an insurgence of ip-based vandalism. I'm hoping this is just a spike owing to the popularity of the comic, but I'm with you; if it doesn't die down, something more drastic is going to have to be done.

But again, thanks for helping...

But now I've read up on {{w|Wikipedia:New_admin_school/Blocking|Wikipedia's block policy}} and from now on I'll be posting {{tl|uw-blockindef}} (which I've bungled fantastically right now, but shortly should be working) which should allow the rare legitimate user (with bad taste in usernames) to reclaim their good account, but allow us to block bad people.

::::As a general rule I loathe my shift key, using more keys to achieve the same goal is wasted time, and I could be called ruthless about wasted time. Saving a single keypress seems petty.

That's my long winded explanation for why I like using {{tl|userbox}} instead of {{tl|UserBox}}.

::::Also, I like the wikipedia userboxen, it's more flexible. And that allows anyone who comes over from Wikipedia to know how to work userboxen here too. That's my case for it.

:::::In CS, I learned that descriptive variable names and easy to recognize naming conventions can save heaps of debugging time.

[[User:Davidy22|Davidy22]][[User talk:Davidy22|<tt>[talk]</tt>]] 07:58, 4 December 2012 (UTC)

:::::: I was asked to comment. Here are my thoughts:
::::::* Regarding CamelCase, it is indeed a neat convention but we don't use it elsewhere on the wiki. In fact, MediaWiki itself, in its early versions, used to rely on CamelCase for linking, but moved to the free-form, space enabled link syntax, which is better in many cases. Not everything converts nicely into CamelCase. So while I appreciate the argument to use CamelCase as the template name, I think the regular case version fits the wiki better. Besides, redirects are cheap and work well, so if the CamelCase title redirects to the lowercase one, whoever wants to use the CamelCase version can still do so seamlessly. Not an issue, therefore.
::::::* I agree with Davidy22 on the parameter names. In fact, the code of the template can be arranged in a more readable form (using whitespace and indentation) so not only its uses can be deciphered, but the template itself too. Renaming parameters is a simple matter, especially for templates with not many uses as these are, which means there isn't a lot of replacements to perform.
:::::: In summary, I think the two templates should definitely be merged and the best features of each kept in the final version: the title being [[Template:userbox]] (with redirects from [[Template:UserBox]] and [[Template:Userbox]]), and the parameters using intuitive names as {{tl|UserBox}}.

== About your new admin powers ==

Actually just the rollback hammer. I've learned this after being burned a few times.

Rollback will actually not revert just the one edit you are looking at, but will go back until it hits a revision that wasn't done by that user, so its useful for pure spam accounts, but if you're just undoing a single edit, you may still want to use the undo tool.

Also, once or twice I actually had it revert all the way back to the last patrolled edit, which meant it actually got rid of the edits of a few anonymous editors too.

Just a caution that with great power comes great responsibility.

== Removed Level 2 headings from Discussion page ==

Hi, I noticed you removed the level 2 headings in the discussion of comic 1188. I'm guessing it's the application of some formatting rule established on this wiki, so I'm curious where I can find a list of these standards that I should adhere to, so I don't make such a mistake again in the future.

:It's not really a formatting convention, more of a workaround to technical limitations of the wiki. The way discussion pages are embedded into comic pages, headings in talk pages cause breakages when tables of contents are spawned.

Perhaps reducing them to ; headings is a better alternative that still marks a new topic.

I created an explanation for 1228 (Prometheus). What I wrote didn't appear for a few minutes and then when I tried to check why, I found you'd deleted a page, but the text I wrote then appeared where I was expecting it. Your comment on the deletion referred to "a thing on the front page" I should have read. I looked for this "thing", but I've still no idea what I did wrong, or what happened with all the page creation / deletion jiggery pokery. I created the explanation after clicking a box which told me to do so if I wanted to provide / improve the explanation. I apologise for my mistake, but perhaps it would be better not to put boxes on the main page which invite edits if those edits end up in the wrong place?

:I manually create the comic page and set it to show up on the front page usually within an hour of every new xkcd comic. The explanation pages for every comic follow a naming convention, with the comic number followed by the comic name. We also make a few redirects for the wiki to use to make the back/forwards buttons work. In addition to that, every explanation page has a template; note how every other page on this site has a particular look to it. The page that you created didn't follow any of that, so I deleted it and copy/pasted it to the correct location.

Now I realise that the "please edit" box should have shown up in the editor, perhaps alarm bells should have wrung.

There are a couple of xkcd comics that link to an extra image on the site when they are clicked. On this wiki, most of the time, the explanations just contain a direct link to this image. However, sometimes, users upload the secondary images and link to those. This is rather inefficient, especially since some images are too large to be displayed directly after they are clicked on the wiki. So, I was wondering if you could delete the few secondary images from the wiki. They are: [[:File:lakes and oceans large.png]], [[:File:na make it better.png]], [[:File:subways large.png]], and [[:File:lojban translated.png]].

In addition, I suggest that some [[Special:UnusedFiles|unused files]] also be nuked. [[:File:combination vision test fullcolor.jpg]] was superseded by [[:File:combination vision test fullcolor.png]]. [[:File:22 pieces.png]] was uploaded by a user who apparently just wanted to show off his Tetris skills.

== 1269: Privacy Opinions‎ ==

This edit war is useless. The add is just '''TL;DR'''. And I'm sure even you did not read it all. Please keep explains as short as possible, otherwise people don't read. For understanding my post read this (read it all, there is a final statement at the bottom):
According to the title, the comic is about “opinions on internet privacy” in general. Six positions are offered as options. Four of the positions are tagged negatively by the author by their subtitles alone: the Crypto Nut, the Conspiracist, the Nihilist, and the Exhibitionist, all of which have negative valences in contemporary English. That the viewer is encouraged to identify negatively with these four positions is further encouraged by the content of the panels, as those characters are depicted either as having such boring lives that they have no need for privacy (the Crypto Nut, the Nihilist), or as being crazy (the Conspiracist, the Exhibitionist).
A fifth position, the Philosopher, is tagged somewhat ambivalently by the author: Megan is depicted as boring her interlocutor, yet in the title text, the author admits that he is usually the Philosopher. Also, “Philosopher” in vernacular English is neutrally valenced, potentially having the ability to expound either wisdom (sophia) or sophistry. It is also a synonym for Sage, the sixth position. As the author condones his own movement from Philosopher to Sage, he thus indicates that the Philosopher is to be viewed negatively, even if it is a tempting position to hold.
The title of the sixth position, the “Sage”, is positively valenced in contemporary English, and the author in the title text states that once he obtains a “burrito” – i.e., a “real” thing, he switches from the Philosopher to the Sage. The internal evidence presented thus far therefore is entirely consistent; the author encourages the reader to identify with the Sage.
By presenting five negatively tagged positions followed by a positively tagged sixth and final one, the author follows a rhetorical commonplace of listing and refuting a number of positions one by one, concluding with the favored and best one, which is not refuted and should be accepted both on its own merits and by virtue of being the last one standing. The comic therefore implies that no other (significant) positions exist.
Having completed the rhetorical analysis of the comic, we are now in a position to understand the meaning of “Internet Privacy”.
Panels #3 and 5 directly reference the American NSA. Panel #5’s “exhibitionist” also references Google, but the characters in the panel appear to be NSA agents (one wears an official cap and they are viewing the exhibitionist on an official, government-looking monitor). Likewise, the focus of the “Nihilist” is that the joke is on the people who gather the data, rather than those who are subsequently able to make use of it (such as Facebook’s users rather than "Facebook" itself; i.e., Facebook's employees and, by extension, its advertisers). The content of the actual data is only mentioned in panels #2, 4, and 5, and in each panel, it is suggested that it is meaningless or trivial. The Sage underscores the notion that any data known about him does not bother him, and therefore must be meaningless or trivial. The reader is thus encouraged to believe that it does not actually matter whether others discover personal data abou t him/her.
The comic is therefore what social theorists call *reductive*, because it reduces the range of possibilities of “Opinions on Internet Privacy” to an artificially and simplistically narrow subset; in this case, individuals concerned with government or corporate agencies using data that they have gathered on individuals, and the futility of worrying about such things. The comic does not admit the possibility of other “opinions on internet privacy” – namely, that individuals might have legitimate concerns with governmental or corporate uses of their data, let alone other individuals’ access to data that is assembled and distributed by corporations such as Facebook. The comic likewise does not consider the possibility of individuals having more interesting lives than the characters depicted, and therefore very real concerns about their privacy due to the activities that they engage in that are potentially more career limiting (should they be discovered) than obsessing about cryptography or eating a burrito.
The comic is “functionally” reductive, as opposed to “intentionally” reductive, because the reduction is the function or effect of the comic for readers who read it straightforwardly (such as the poster who claimed it was “about” Edward Snowden), whether or not the author intended this reduction to occur. There is not enough internal evidence in the literary text (i.e., the comic) to maintain that the author intentionally excluded other viable opinions on internet privacy; it could be that they are just not on his radar. For example, we do not have enough information in the comic to claim that the author is against civil rights; it could be simply that he doesn’t often think about them. Likewise, it would exceed the evidence of the comic to claim that the author believes that schoolteachers who use the internet to facilitate legal but frowned-upon sexual behaviors should lose their jobs if they are found out due to internet privacy breaches; it could be that the author simply hasn’t bothered to worry about these matters if they don’t affect him personally. This adjudication – whether the comic is “intentionally” reductive or not – may only be made on the basis of external evidence; that is, data known about the author from sources beyond this comic.
Use of such external evidence – historical, personal, psychological information about an author – is valid in determining the meaning of an author’s text, and is increasingly viable due to the accessibility of information about an individual on the internet today.
Additional observations about the comic follow.

Then clicking the picture brings me to this link: [[explain_xkcd:Advertise_Here]]. But, I still do not see any advertisement here at all, only this "wonderful project world", what's wrong?

I would like to pay here for a link to Randall's store (he doesn't know), but it has to be an internal picture to an external link. A user action is required, ask Randall about this security. External clicks do count, embedded content to external sites is a real insecure solution. Many modern browsers will not allow this. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 21:51, 1 October 2013 (UTC)
:The image does belong to us, it's just served by project wonderful when no advertisers are currently bidding on us. The word "advertise" used in the link title is in the verb form, not the noun; that page describes how to advertise on our site. That page contains our advertising guidelines and a few links to our project wonderful bidding page. There, you can create an account and bid on any of the four regions we have on offer. Our minimum rate is USD$3.8 per day, and they let you link any image to any site. If you still can't advertise with us, post imgur links to screenshots to show me what you're doing.
:Have you not said in the past that you are an employed software developer? Instead of advertising a site wholly unaffiliated to you, why not ask your boss to try his hand at advertising on explain xkcd? It's cheaper than most advertising outlets, and we have a large and valuable audience for your average technology company. Your company can probably easily muster the ~$15 per day needed to advertise in all our available regions, and the process takes about as long as creating an account on any other site on the internet.

Have you thought about trying [[mw:Extension:Comments|Extension:Comments]]? It was recently updated (July 2013) and looks like it would make commenting the explanations much more user-friendly. Could you make a little experiment to see if it works well? Say, install it so we can test and see if it works well?

== New comics BOT ==

I think that BOT is doing the job right now. Maybe there is a possibility to install it on this server, not much but some PERL modules are required, it should work on any OS. Nevertheless since I could see the updates in general did happen at 04:00 UTC I will implement a new script starting at 04:00 UTC, polling again after that again. But since I don't want to poll xkcd too much that poll would stop after fifteen minutes. Then there will be just a five minute schedule, until a new comic is found.

BTW: <nowiki>$text .= "{{comicsrow|$comic_num|$date|$comic_name|$picture_name}}\n"; </nowiki> means I will always add the optional parameter for the picture. Not all picture did work properly in the past, so I decided to include this parameter to get a working picture link on the main page. Any suggestions are welcome. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 21:50, 26 November 2013 (UTC)
:I have an idea for that, but I have a metric buttload of things that I need to do by the end of this week. I've seen comics come out several hours late so I think polling for four hours would still be apt, and I'm sure Randall's server could handle us polling him a little faster. Having a explanation page up at the same time as a new comic is really huge. I believe I have a solution for the comicsrow problem, but I also don't know Perl. I could probably figure it out in a weekend though. '''[[User:Davidy22|{{Color|#707|David}}y²²]]'''[[User talk:Davidy22|<tt>[talk]</tt>]] 01:19, 27 November 2013 (UTC)

== BOT uploads at the comic list ==

Hi,
I can remove that "Picture.png" add, but I think it's more safe to use this optional parameter. Sometimes upper case and lower case did cause some problems. I'm trying to prevent this by providing the image link my BOT did upload here.

On January 1 my BOT did fail because the picture was not accepted at this Wiki, and my BOT stops on every unexpected error. The BOT doesn't understand Randall and so, when the BOT is running on problems it simply does nothing.

I've had serious problems to connect this site since a few deys, I don't understand why, but my BOT is doing it's job as planed.

Looking forward to some translations...

== Template:comic ==

Isn't this just a revert and a freeze to a former revert done by me? Others did play then again on the main page appearance, but changes at this should be only possible for people not experimenting. The entire main page has to be protected. That page isn't a playground.

And on that admin discussions on me: My most posts are related to language, layout, and something — and I still don't like all those esoteric explains on ASSes, PENISpumps, ... But an admin has to work mostly on different issues.

Randall does primarily focus on "romance, sarcasm, math, and language.". Randall does more, so the SEX category is here, but I think we have to focus on the "primarily focus" at the headlines on explain pages first.

My advice here: Do NOT try to enhance well working templates, other statements are much more important.

== "Feeling old" category ==

Hello, Davidy22. I noticed that you deleted the "Feeling old" category I made a while ago due to being "tenuous, not significant enough." In the interest of becoming a better contributor to the wiki, could you explain further on significance for a new category?

I realize that there are various qualifications that a category has to fulfill, lest it only add clutter to the wiki. A category ought to be simple, memorable, and concise. It should refer to something within or about the strip, be deliberate, and be objective. And, ideally, it should apply to a fair number of strips. I figured that the four strips that included the motif of "character/Randall reflects on how distant the seemingly-recent past is" all used it significantly, as a central theme or as a punchline. I personally feel that Randall hasn't exhausted his use of this motif, and therefore it warrants its own category for future comics, saving time in future explanations and aiding readers of past explanations.

(My one personal issue with it is that the phrase "feeling old" does not feel concise or specific enough, but I couldn't think of a single word or a better two-word phrase to describe it.) -- [[Special:Contributions/108.162.216.21|108.162.216.21]] 18:18, 12 August 2014 (UTC)

:I hope you (Or Davidy22) don't mind me starting off this conversation. Categories are not meant to be used as a tag cloud. Categories are a concrete thing in the comic such as [[:Category:Comics with color]], [[:Category:Red Spiders]]. They are not motifs or feelings about the comic. We don't have categories for happy comics and sad comics, and I can't think of a persuasive enough argument to allow them. Until there's a significant number of comics with "I feel old" or "I'm getting old" or "#FeelingOld" (eww) in the text, I'd hold off on trying to push this one through. [[User:Lcarsos|lcarsos]]_a ([[User talk:Lcarsos|talk]]) 05:55, 13 August 2014 (UTC)
::Part of the deletion ''was'' because it only had four comics under it.

::: Okay, so ''feeling'' old is a bad category name. Categories that sound subjective in general are bad. Perhaps "Aging" could work? And also, courtesy of two particular xkcd blogs, I know of at least 10 comics that would belong to it: [[218]], [[354]], [[447]], [[493]], [[647]], [[891]], [[973]], [[1093]], [[1393]], and the recently posted [[1408]]. - [[Special:Contributions/108.162.216.21|108.162.216.21]] 03:38, 16 August 2014 (UTC)

== Dont change other peoples comments ==

When the user clicks "add a topic" in the comments block a new section is added. When a user does this you modify it to a heading style you prefer. This is against every design principal I know of. You have 3 legitimate choices: remove the button, style the header so it pleases you more, or let it be. Since this is a standard part of the wiki and updading versions would likely undo your changes, I would sugest that you simply learn to live with it, as it is not objectivly ugly.
When I find myself in times of trouble
Mother Mary comes to me
Speaking words of wisdom, let it be
And in my hour of darkness
She is standing right in front of me

:It's not actually done because the header is ugly, it's done because of an error case that occurs when the discussion page is transcluded onto the main explanation page, that came up a while back. It would probably be better to remove that button instead of having to manually change every discussion page header, and I'll get to that when I have the time. Also, note how I only modify headers in explanation talk pages, where the error can occur; headers in user talk pages and the community portal are unchanged. Also, updating between mediawiki versions does not change the contents of (most) pages, so it wouldn't actually undo what I'm doing.

::::With respect, referring to 'Only having voted for a chimpanzee twice' is (to me at least) an obvious racial slur aimed at Obama.

:::::Chimp in the general lexicon is used to describe someone mentally challenged, not black. I must say it's quite hard to discern exactly who or what he's talking about because it feels like he's just making comments for the sake of making lots of comments. His statement about texas being granted statehood probably doesn't support the idea that he's talking about Obama, since they're not very supportive of him to begin with. Texas to my knowledge has been a republican state, so unless he really doesn't know what he's talking about, I'd say it's more likely that he's talking about one or more of the recent Republican presidents.

::Format indeed... also I understand what you mean about self explanatory - I'd say at least 85% of each entry is quite plain, simple, and straightforward. Most of the humor of the feature is not traditional "ah-ha!" humor (that comes from revelation of a twist on assumptions, or which might benefit from explanation). Every once in a while, though, that remaining 15% (often from the images, but sometimes from a {{w|factlet}} or two) contains a few nuggets of knowledge that make me yearn for discussion or comment, and occasionally clarification to one degree or another. In addition to possible issues of cherry-picking what's explained, and questions on how to format it, there's the question of the variability in release date of the comics (used to be every Tuesday, then Thursday and, if I'm not mistaken, the last two(?) have been on Friday, with a few weeks missed (sometimes with and sometimes without notice or explanation) - so how to catalog that?

== Template:i ==

I created that template for a reason. Unicode doesn't work right in many circumstances, especially on phones. Now people without Unicode support will see incorrect equations. Plus typing in a Unicode character is not easy, and not having an easy way to do it will guarantee it won't be used. That's why character templates exist on other wikis.

I copied the way of making the imaginary constant from Wikipedia. That's how the math template works. The Unicode version doesn't even look like an i in many fonts--the dot is missing. It looks like a weird squiggle that people won't recognize.

I really wish you would have done like other wikis and had a discussion (and let me know) before just deleting something. I'm lucky I happened to leave the tab open and happened to see it was deleted.

== Strong Language ==

Hey - I find it interesting that someone chose to create the category about "strong language" or something that you chose to delete because it had one comic. There are countless examples of "strong language", pretty much irrespective of what you consider to be "strong" (just search for one of the various "strong" words) but it's fascinating noone has felt strongly enough about it to make a category until 2015 -- [[User:Brettpeirce|Brettpeirce]] ([[User talk:Brettpeirce|talk]]) 15:04, 26 January 2015 (UTC)
:It's also that "Strong language" is a really subjective category name that doesn't hold the same boundary for everyone, and is gonna be tough to populate to a degree that satisfies everyone. Although the person who made the category still frequents the wiki, so maybe he's capable of maintaining it.

My BOT still got the old comic while other people did upload the new one in a corrupt way. So let's define some rules for my BOT to be slightly more violent. For now I'm only checking if also the comic-name redirect exists. But I think that my BOT should test all required updates here, and if something is missing it would do a clean job here.

:This thread has gone too deep, I'm coming out to first level. ;-) Alright, you could try couple of things. You first want to know where the spammers are coming from and if you can stop them at source. You might have to add tracking on what previous site is the user coming from. If all spam bots are coming from single source, we could request the source site that links us to modify/hide their links. Second, are the spam accounts posting from different IPs every time ? Otherwise you could place a temporary IP based ban. Third, I'm interested in knowing why the bots are creating accounts while they could edit the pages anonymously. This might tell us about the algorithm they are using. And how are accounts treated differently than anon users ? Do they not get captcha while posting ? In which case, you could enable captacha's for users with accounts as well. EDIT: I'm the same guy as the OP of this thread (IP : 199.27.130.216).

:Alright, so, we're using cloudflare as a CDN and intermediary for traffic for performance reasons, and they obscure IP addresses. There's a fix that we've yet to implement, but something always seems to get in the way in real life. IP banning is a little weak because of this. Users with accounts also get CAPTCHA'd, until they are at least 3 days old and have at least 10 edits. I'm not sure why the spambots make accounts, besides gunking up our database with more garbage.

== Creation of disussion pages for new comics ==

Hi Davidy22. I have recently seen at least two cases where people wish to make a comment on a new comic, but cannot because the page has no been created (and they do not have the right to do so). For instance I even had [[User_talk:Kynde#Please_create_the_discussion_page_for_today.27s_comic.|a message]] from someone who could see I was making changes (I guess). Would it be possible for the BOT to create the discussion page empty like I did here [[Talk:1654: Universal Install Script]], with a not shown reminder about signing comments?

== Errors in counting "known appearances" for characters ==

Hi Davidy22. I have seen this error more than once, and today with a comic featuring [[Danish]] it once again became very clear that something was wrong (impossible to spot for Cueball and the other main characters). On her page it says 16 know appearances. But on the page [[:Category:Comics featuring Danish]] it says 18, and even though one of these are the main page (which will change Wednesday when the next comic is released) there is one too few in the count. Maybe it will correct it self later? I think I have seen the same for [[Hair Bun Girl]] but her count is up to date now. But it is typically on the release days that people would pass these pages, so it is a shame if it first works later. Just so you can check it out, and if you know what's going on let me know ;-) --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 13:08, 21 March 2016 (UTC)
:So, the way the explanation on the main page works, we take the number in [[Template:LATESTCOMIC]] and find the page that is named that number. Every comic in this wiki must have a correspoding page for their number that redirects to the comic explanation to make the forward/backward buttons work and for the main page to automatically point to the latest explanation without need for us to allow bots to modify the main page directly. The entire text of the explanation is included in the main page in this process, including categories. The [[Template:comic discussion|discussion template]] actually has a check for the title of the current page, and it doesn't render if it's the main page. We can do a similar thing to prevent categories from being assimilated into the main page, create a template that inserts the check around the categories and have a bot remove the template when the comic isn't the newest one anymore.

I think someone removed the incomplete status from 1338: Land Mammals but no one picked a new one for the spotlight.

== Category that should be deleted ==

Hi Davidy22. When [[1724]] came up someone added the [[:Category:Axiom of Choice]]. That took this category up to three. But I believe this may be warranted to keep that category. But I'll leave that to you. You deleted one I made once with three comics [http://www.explainxkcd.com/wiki/index.php?title=Category:Ba%27al&action=edit&redlink=1 Category:Ba'al] (see [[1419: On the Phone]]).

But there was another category: [[:Category:Set theory]], which only referred to the two old Axiom of Choice comics and then as an under category had the Axiom of Choice category. So it was redundant. So I have removed any references to this category and moved relevant text to the axiom of choice.

So I will suggest that the set theory category page is deleted as with Ba'al. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 20:12, 7 September 2016 (UTC)

:Oh, how'd I miss that. Removed both categories, the axiom of choice category was too narrow and too infrequent to merit a category page. Thanks for telling me. '''[[User:Davidy22|{{Color|#707|David}}y²²]]'''[[User talk:Davidy22|<tt>[talk]</tt>]] 08:56, 10 September 2016 (UTC)
::I guess it is hard to keep up with all that happens here. I have made several new categories but now try to wait for at least five entries. For instance [[:Category:Google Glass]] and [[:Category:Climate change]] are recent addition, the latter very actual you could say with [[1732]]... And then I also just added [[Blondie]] and [[:Category:News anchor]] as new categories. I rephrased all three axiom of choice comics to refer to each other rather than to the category, so there is no loss of data for deleting both those categories. Let me know if you think I create too narrow categories. But as soon as there are more than five of anything, it become very tedious to refer back to each of them from each comic and a category is much to prefer. And with five already the chance that Randall soon add more comics is realistic. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 20:20, 13 September 2016 (UTC)

== Current incomplete explanation ==

The "current incomplete explanation in the spotlight" has been the same for 5 months now and the last edit was almost a month ago.
May I suggest to either (a) mark the comic as complete and move on or (b) put a different comic in the spotlight and send this one back to the backlog?

Pro (a): All regular visitors who are willing to edit have probably read the notice, visited the explanation multiple times and simply don't have anything more to add at this point and won't be re-reading everything again.

Pro (b): If the comic comes into spotlight again at a later date, people are more likely to click on it because it's different from their last visit and they may actually go through with re-reading everything.

P.S. What's the criteria for completion on a comic like this where you can essentially explore a whole world and write about pretty much anything in it?

This kind of stuff does happen with the larger comics though, the pages get really unwieldy and they're older pages that people aren't necessarily interested in.

>I'm not willing to keep making points that you'll brush off as false and state your own claims as true

It is literally the other way round. It is you who declare that 'signing' is good and I whose examples how it isn't you consistently ignore and vocally state that I have failed to provide. In light of this eerie brand of apparent self-victimization of yours, it doesn't seem to make much sense any longer to point out the nonsense of how you claim to have to 'clean mess' while the 'mess' in question is literally just freedom from screen clutter.

== Sad comic trivia ==

Hi Davidy.

As you can see I'm back editing. Specifically I have been busy connecting the sad post Trumps election comics and have made the post as a trivia to [[1790: Sad]] - see [[1790#Sad_comics|here]].

I would like to hear your opinion on the placement. I do not think these comics fit into a category as their relation needs to be seen in a broader light that I have tried to shine here. But maybe a separate page could be created, but I really do not know what to call it. Sad comics in general would also cover lots of other comics especially many of the cancer comics. So Sad Comics alone would not do it. Also Trump should not be part of the name, as Randall has as far as I know never mentioned his name in his comics yet? But to me it is crystal clear that the comic is either a direct reaction to the election or to peoples behavior online (or around Randall). Although I'm quite sure he is sad about the way politic is going especially with his concern for global warming.

When I first made the trivia someone deleted it entirely, but it was also just a short sum up of those three other comics [[Blame]], [[Negativity]] and [[1779: 2017|2017]]. Now I have also included he [[I'm With Her]] as it seems to have started the series of sad comics. But I think it is important for the understanding of these comics to have them collected somewhere, and if they are sad, then a comic called [[Sad]] seems to be the right place if no single page would do.

What do you think about this, and about my current trivia on Sad's page?
:--[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 20:57, 28 January 2017 (UTC)
:Given the absence direct references to Trump in the comic, I would refrain from implicating him until Randall makes it explicitly clear that he's talking about Trump. The portions that talk about other comics' relation to Trump definitely fall outside the scope of the explanation page for 1790 and their removal was probably appropriate. Also, the word sad is a little tenuous of a link to trump and 1761, 1773 and 1779 all seem like similarly loose connections. They all depict feelings that may result from the election, but are not necessarily directly connected or caused by the election and linking them in a category or section for this and not other, older comics showing sadness is going to be difficult to support in the future. Also, constructing links between miscellaneous comics to Trump when none of them directly reference Trump seems like taking a side when we as a wiki should be firmly neutral.

::Hi Davidy. Thanks for the constructive critique. What about the release days in relation the the election, the electoral college vote, new year (of the year he will be president) and finally the first comic after his first real workday. Personally I'm not in any doubt that his sad comics is a result of the election. Maybe they reflect more on other peoples sadness than Randall's own, but with the [[1732]] comic in mind I'm sure he is not only worried about the wall and Muslims banned from the states, but really really worried about the global warming that Trump will help increase. And he has made a direct comic related to his opinion on Trump in I'm With Her. By placing it in a trivia people can also choose not to read it, and I find that the increase in such sad comics is very relevant. I do not remember any real sad comics the year before his election.--[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 11:31, 29 January 2017 (UTC)
:::PS Just ran through the all comics a year back from I'm with her (or rather Blame) and on from blame. There are four depressing in those last 30 comics Blame included. The only remotely sad or disturbing comic in the 157 a year back from Blame is the global warming comic I just linked above here. And that is not really sad because it is also funny. But the end is scary. Also I checked the 15 pages listed under cancer. I would only say five of those are sad, the other are mainly funny or just something to be thoughtful of. The five sad comics came out over a range of 324 comics [[818]] in November 2010 until [[1141]] November 2012. SO instead of four in just three months it was only five over two years and on a subject he had real cause to be sad, negative or worried about. So I think it is very relevant for explain xkcd to note this increase in sad comics. Of course there could have been other sad comics in between those, but I just don't remember many comics like this. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 11:59, 29 January 2017 (UTC)
::::The difference between the cancer category and these comics that may or may not have something to do with Trump is that there are explicit references to cancer in the comics in the cancer category. It takes some amount of inference to link those four comics to Trump, and they aren't necessarily linked to the election. They may typify things that Randall noticed after the election, but they can be used in vastly different contexts and the correlation does not necessarily indication causation. The only comic among the five in the trivia section that genuinely merits a sizeable amount of of text on trump is [[1756]], because he's actually directly relevant to the comic.

:::::Hmmm. So would you suggest to remove it completely from the trivia. I could put it on my own page as a theory and link people with interest to it from the comics talk pages. Or would it be enough to remove Trump references and then keep the four sad negative comics as a worth of mentioning due to the fact that they do seem to take a negative view of the world which is not usually Randall's style. I'm of course sad... because I put a lot of work into that section. Just like I just did with the so far empty transcript of [[1461:_Payloads]] (not that much though!).

If users want to discuss speculative links between comics that aren't necessarily mentioned within the comic itself, they should do it in the discussion page and not the comic explanation.

== Sitenotice ==

Could the [[Mediawiki:Sitenotice|sitenotice]] be updated to randomly pull a comic from the [[:Category:Incomplete explanations|incomplete explanations category]]? There's an example of how to do this on {{w|Template:Random page in category|Wikipedia}}. And perhaps it could be set to update after a fixed interval of time - say, a week? It would be easier than updating it manually, and you could avoid situations where the highlighted "incomplete explanation" is no longer incomplete, but remains in the sitenotice.

EDIT: Well, it seems that the second part is not really feasible. However, I still think the first part should be implemented. Instead of linking to a specific comic that could easily go stale, the sitenotice could just say "click here to see an incomplete comic" or something like that. The actual link would take you to a random incomplete comic using the aforementioned method. --[[User:Oneforfortytwo|Oneforfortytwo]] ([[User talk:Oneforfortytwo|talk]]) 05:18, 10 June 2017 (UTC)

:::From my experience (long enough, without a username as I am) the volume and/or frequency is 'normal'.

:Well, you might still be able to call them holes. They would be if they were fully rectangles. --[[User:BlackBeret|BlackBeret]] ([[User talk:BlackBeret|talk]]) 12:59, 27 May 2022 (UTC)

: Gridiron football's field contains two areas (the endzones) that can be thought of as not being part of the "normal" field of play, for lack of a better way of saying that pre-coffee. Association football likewise has the areas within the nets. [[User:Noëlle|Noëlle]] ([[User talk:Noëlle|talk]]) 13:05, 27 May 2022 (UTC)

: My immediate thoughts were also that football (soccer) and football (gridiron) are the same, or indeed the other way round. In both cases the closed hole (assuming not a Y-like vertical holder, but H-like as per rugby football) plays no more or less topological part. Threading through the hole from behind has no relevence in either, and in fact defining it as a region that is 'a special enclosed gap with meaning' (which doesn't really matter in the topology sense, just like golf would be a topologically hole-less surface and as a coffee-cup's inside 'dimple' doesn't count, just its handle-hole that makes it equivalent to a doughnut) actually counts for something in association football.

:: It's not the space bounded by the goal that is the 'hole' - it's the goal post itself (or in the case of the high jump, it's the bar, not the space under it). The reason soccer doesn't have 'holes' where the goals are is that they're positioned on the edge of the playable area - you can't play around the bars, because as soon as you cross the goal line you're out of play. And it doesn't matter whether it's a Y-shaped or H-shaped goal - topologically, they both form one continuous 'hole'. [[Special:Contributions/172.70.91.80|172.70.91.80]] 13:37, 27 May 2022 (UTC)

::: I don't think that's the reason why soccer doesn't have holes. The goalposts in football are also outside the playable area, and so are the poles in volleyball. I think soccer is listed as zero-holes because soccer goals are typically not fixed to the field, and are instead separate objects that can be dragged around and removed from the field. On the other hand, the same is true of volleyball and badminton nets (and those nets contain many holes!) so the comic seems a bit inconsistent.[[Special:Contributions/172.70.175.146|172.70.175.146]] 14:05, 27 May 2022 (UTC)

:::: Speaking from a "football is soccer" nation (well, mostly, the exceptional subregions would argue that it's rugby) a soccer goal is typically ''not'' draggable around the field, but permanent (or a unit frame that has to be painstakingly hoisted out of the ground if you ''don't'' want them in your football stadium, when you repurpose it for other purposes) and it's only the optional net that gets added to the park's permanent goalposts for the official five-aside competition evening or day of the weekend. Draggable goalposts need a further level of intermediate organisation that goes beyond the typical "shipping container with windows cut in it (with shutters bolted over them) as a cheap changing room/officials' cabin" that might be found near the edge of the field but rarely even has as much as a corner flag left in them, between games".
:::: I presume that US 'football' posts are considered holes because they are an infinitely-tall window (even though the delineating poles only reach so high) that is a meaningful slice (where the goal is, you have to loop around it in mutually different unsimplifiable paths to reach the other side), but then that should make for ''two'' holes per end, if you count getting a field-goal and then returning round the sides (or vice-versa) as another valid surface-path.
:::: ...but, yeah, I can imagine the problem of definition (and cultural famiarity) here is going to produce more problems even than the understanding of topology. One of the less internationally-accepted comics, this. [[Special:Contributions/172.70.85.177|172.70.85.177]] 18:51, 27 May 2022 (UTC)
: O_O . Randall is united-statesian, so football means the thing where you tackle each other and hold the ball in your hands. I've never been into football, and I've always seen it with two large goal posts with a horizontal bar between them. The hole is formed under the horizontal bar. When I played football in computer games, you had to get the ball over the horizontal bar. After this, I'll search the web to see if the horizontal bar still exists. Regarding soccer, there aren't two holes because the nets are closed at the back. You cannot pass through the field structure by going through a goal: you bump into the net the ball bounces off of when a goal is made. So, Randall is considering soccer fields topologically equivalent to a plane (ignoring all the holes in the netting). [[Special:Contributions/172.70.114.229|172.70.114.229]] 14:58, 28 May 2022 (UTC)

::I agree about soccer; the explanation should be that soccer goals (with net) are topologically part of the plane. The same is true of ice hockey, even though you can travel "around" the net, it is topologically part of the field with no holes.

::Agreed. Soccer goals are shaped such that their bottoms connect smoothly to the ground in a single continuous piece. So they are topologically equivalent to the plane. This wouldn't be the case if not for the back part holding the net. That's unlike basketball hoops, which are actual holes. The holes in football must be referring to the H-shaped uprights that were standard until 1967 in professional leagues and are still seen in some high school fields and even a couple college fields.

In rugby (both League and Union) the goalposts are within the field of play: significant game activity takes place behind them. This is not the case with soccer. I have no clue what difference this makes topologically.

I assumed the reference was that very old cell phones (1990s etc.) were enormous - think carphones; technology allowed them to shrink (giving, say, the Nokia 8850 I owned in 1999 and the original smallish iPhone), and then recent phones have (on average) grown again as the benefits of a larger screen area have been seen to outweigh the convenience of a smaller device. Also older phones tended to have batteries that lasted longer, mostly because neither the screen nor the processor were pulling much power. It's not just that the original iPhone was smaller than current ones (nor, for some of us, does the original iPhone count as an "early cellphone"). Am I alone in this interpretation?

2168: Reading in the Original

{{comic
| number = 2168
| date = June 26, 2019
| title = Reading in the Original
| image = reading_in_the_original.png
| titletext = The articles are much shorter, but I assume that's because this version predates the merger with the Hawaiian text that created the modern Hawaiian-Greek hybrid wiki-pedia.
}}

==Explanation==
Many academics and aficionados argue that studying texts in the original language is more valuable than reading translations. The argument is that translations are rarely able to fully capture all of the nuances, linguistic subtleties and intent of the original author, and may even alter the meaning in some way due to the translator's interpretation and word choices. The drawback to this is that it requires the reader to be sufficiently fluent in whatever language the text is written. Critically, a reader of the original source also needs to understand the cultural and historical context of the original work, something a professional translator might deal with much better. This can even happen when working with archaic texts in the same language, as certain references and phrases may have had a significance which was lost over time.

Cueball's commenting that he read works "in the original Greek" implies a high-level of literary scholarship, as this phrase is associated with scholars studying ancient Greek texts, which form a significant part of the foundational works of Western literature.

A similar thing happens with dubbed movies or TV series/anime, with many people remarking that they instead prefer to watch the original version (sometimes with subtitles), instead of the dubbed version.

The joke in this comic is that Cueball has apparently taken the time to learn Greek in order to read the [https://el.wikipedia.org Greek-language Wikipedia] in that language, believing it to be the "original" one. {{w|Wikipedia}} was originally launched as a single English-language edition encyclopedia, but Cueball apparently treats it as though it was originally written in Greek. (An [https://incubator.wikimedia.org/wiki/Wp/grc Ancient Greek Wikipedia test project] also exists, but is not nearly as large as the modern Greek one and isn't available through the languages box.) Wikipedia has editions in about 300 languages; the 'languages' box that Cueball mentions does link to the corresponding page in other languages when they are available, but such pages are not usually translations of each other, having been written separately. Cueball's dedication to appearing to be a committed scholar is therefore contrasted with the ignorance of not understanding that Greek is not the original language of every text. Megan, recognizing that Wikipedia articles were not originally in Greek, exclaims that "That's not how that works!"

The movie ''Star Trek VI: The Undiscovered Country'' has a joke concerning someone speaking of a foreign "original" language of something that actually was originally written in English: Chancellor Gorkon says, "You have not experienced Shakespeare until you've read it in the [[wikia:w:c:klingon:Shakespeare|original Klingon]]." (In reality, Shakespeare lived in England, and wrote in English, not Klingon.)[citation needed]

The title text combines two jokes. First, the reference to pages being "much shorter" is because the English language Wikipedia has the most editors and is the most developed; outside of areas of intense interest to Greeks, most pages would be more complete on the English Wikipedia, which would normally be a sign to Cueball that his interpretation that Greek was the original text is incorrect. Second, the way he explains away this contradiction is an etymology joke, since "Wikipedia" was coined from two parts, "[[wikt:wiki#English|wiki]]", from Hawaiian, and "[[wikt:-pedia|pedia]]", from Greek. However, words having roots in different languages is common and does not signify any link between the separate languages; for example, while the word "Wikipedia" does have etymological roots in Hawaiian and Greek, it is not true that the site was originally composed of texts written in Hawaiian and Greek. In Hawaiian, [[wikt:wiki#Hawaiian|wiki]] means quick. In Greek, the suffix [[wikt:-pedia|pedia]] is related to learning, which makes Wikipedia mean "quick learning" when combining these two languages.

}}

==Explanation==

In the comic, [[Knit Cap]] is on top of a high mountain in a remote location (second comic in a row with knit cap). Mobile devices frequently launch a popup telling users to choose a network to connect to. Knit Cap sees a WiFi network name listed on a handheld device, perhaps a cell phone. This is something you would expect in a city, but certainly not on a mountain top, hence the joke, that what produced these WiFi networks are unknown, but seem to be distributed randomly over the face of the Earth, disregarding nearness to technology.

Cryptic {{w|Wi-Fi}} (or WiFi) network names, called {{w|Service set (802.11 network)|Service Set Identifiers}} (SSIDs) are part of the joke about not knowing where the corresponding {{w|wireless router}} is located, suggesting they are unexplained phenomena instead of wireless radio devices. Some of the earliest WiFi devices like printers and {{w|internet}} routers advertised cryptic SSIDs, as do many of them today. In 1998, {{w|Lucent}} introduced the [https://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan-IEEE.html WaveLAN IEEE], the first {{w|integrated circuit}} chip set supporting the {{w|IEEE 802.11}} wireless {{w|LAN}} protocol, spinning off {{w|Agere Systems}} to produce them in 2000. WiFi followed mid-1990s short-range wireless networks like {{w|Bluetooth}} and radio internet protocols like the 1980s {{w|KA9Q}}, with roots going back to the earliest {{w|ticker tape}} digital telegraphy systems from the mid-1850s. [https://techtalk.gfi.com/the-31-funniest-ssids-ive-ever-seen/ Humorous SSID names] are not uncommon.

The SSID displayed is '''Toshiba-U2187-OfficeLink-Net46UHZ''' which is 33 characters long, unfortunately one character more than are allowed. {{w|Toshiba}} is a multinational electronics conglomerate manufacturing many products including untold multitudes of different kinds of printers over the years. Such devices often have embedded {{w|wireless access point|wireless access points}} including the manufacturer name in the SSID. Many network names contain words like Net, Office or Link. The code might indicate a model U2187 device from Toshiba named (or having an interface program named) OfficeLink, which has a sub-model number or operates on a wireless network designated 46UHZ. That "Hz" is an abbreviation for {{w|Hertz}} suggests that designation may or may not have something to do with the frequency on which the transmitting device operates. 48 microhertz corresponds to a period of 4.1 per day, or a radio wavelength 41 times as far as the Earth is from the Sun. Or U2187 could be the {{w|Unicode}} character [https://www.fileformat.info/info/unicode/char/2187/index.htm code for the Roman numeral 50,000 spelled "ↇ"] or a serial number for a user or a utility pole. We don't know whether the SSID is connected to a network of more than one or is just one device. The padlock icon indicates that a password is required to communicate. The "join other network" option allows for manually typing SSIDs to attempt to connect with networks which are not configured to display their SSIDs.

While the most likely explanation in an office environment might be a printer plugged in somewhere nearby, other possibilities include a [https://www.youtube.com/watch?v=AJKjnZe4B-M marsupial delivery drone,] television, cryptocurrency mining rig, speaker, pacemaker, alarm system, [https://twitter.com/Theteamatx/status/1162762591677997056 offshore flying wind turbine,] fashion accessory, autonomous antimissile defense system node, hobby project, surveillance device, {{w|Loon LLC|balloon}}, distributed denial of service attack platform malware-infested coffee pot, {{w|Starlink (satellite constellation)|satellite}}, vending machine, [https://x.company/projects/foghorn seawater dialysis station,] telecommunication facility, {{w|Facebook Aquila|solar-powered drone}}, distributed exoskeleton, [https://www.youtube.com/watch?v=tSx_UywxF6o visiting interstellar] [https://www.youtube.com/watch?v=H2f0Wd3zNj0 colony(?) ship,] power-to-gas pipeline valve, [http://www.geekculture.com/joyoftech/joyarchives/2340.html ransomware worm nest,] or anything else in the Wifi {{w|Internet of Things}}. Sometimes, the {{w|ionosphere}} reflects radio waves, vastly increasing the distance that they can travel to and from remote locations, but this {{w|skywave}} propagation normally affects frequencies below 30 MHz, and never above 300 MHz, so they couldn't be the cause of receiving far away Wifi signals, which are 900 MHz and above.

Network names can be used to track the geographic locations of mobile devices, for example in the {{w|Wi-Fi positioning system}}. Google {{w|street view}} equipment records locations of networks to assist with {{w|geolocation}}. Location information can be searched in tools like [https://wigle.net/ Wigle] or [https://openwifimap.net/ OpenWifiMap]. The {{w|Institute of Electrical and Electronics Engineers}} (IEEE) committee number for WiFi is 802.11, which is composed of sub-committees like {{w|IEEE 802.11ad|802.11ad}}, designing the 60 GHz Multiple Gigabit Wireless System (MGWS) and {{w|IEEE 802.11ay|802.11ay}} working on {{w|MIMO|multiple input, multiple output}} (MIMO) bandwidth enhancements. This [https://www.toshibatec.com/cnt/products_overseas/printer2/mobile_printer/b-fp3d/ portable Toshiba printer] supports the "802.11 a/b/g/n" WiFi protocols. The {{w|List of router firmware projects|software which produces SSID listings}} is administered by {{w|List of wireless community networks by region|network communities}} and depends on {{w|Wireless mesh network|mesh configurations}}. (Please see also [[1785: Wifi]].) Alternatives include [https://news.ycombinator.com/item?id=20861948 bluetooth mesh networks] and other {{w|wireless ad hoc network|''ad hoc'' networks}} to provide internet connectivity services.

The title text indicates that the first WiFi networking client interface displayed unexpected SSIDs. If true, this could potentially rule out all of the alternative explanations other than an alien visitation, a software bug, rogue industrial espionage, time travel, trans-multiverse or trans-dimensional communication, hardware misconfiguration, the {{w|simulation hypothesis}}, or the supernatural. (It is worth noting that cryptic-sounding WiFi networks generated by a time-traveling alien entity as a trap was used as a plot device in the 2013 ''{{w|Doctor Who}}'' episode "{{w|The Bells of Saint John}}.")

}}

==Explanation==
''{{w|Breakout (video game)|Breakout}}'' is a video game first created in 1976, and since then it has gained much popularity and has been recreated in many different versions. In the game, the player controls a horizontal 'bat' at the bottom of the screen to make it move left or right. Above it are several layers of bricks that are destroyed when hit by the ball. The ball is not affected by gravity and will float around, bouncing off the walls, bricks, and the bat. The aim of the game is to keep the ball from touching the bottom of the screen (by deflecting it with the bat) long enough for the ball to hit and destroy all of the bricks.

[[Cueball]]'s approach to the game is to actually stand underneath a brick archway and throw a tennis ball at the structure above him in an attempt to destroy the bricks. Naturally, the physics in the game don't work in real life,{{citation needed}} and the aftermath of Cueball's actions is that one of the bricks in the archway comes loose and falls onto Cueball's head, causing possibly fatal damage.

The sentence at the bottom of the comic points out the illogical nature of the game when compared to real life.

The title text relates to a {{w|TI-86|programmable calculator}} from the late 1990s that could have a ''Breakout''-like game easily programmed into. This calculator, and others like it, were a requirement in many high school advanced math classes in the United States after the early 1990s, despite costing over $100. [[Randall]] speculates that, given the amount of distraction this simple game provided him back then, he would not be able to focus on study at all with modern technical instruments like {{w|Laptop|laptops}} using {{w|Wi-Fi|wireless LANs}}.

1443: Language Nerd

| titletext = Not to go all sentence fragment on you.
}}

==Explanation==
{{w|Part of speech|Parts of speech}} can be treated fluidly, in English and other languages. For example, "medalled" has been coined as a word meaning "gained a medal" in a sporting competition, implying the existence of the verb "to medal" meaning "to win a medal". This is a {{w|Trope (Literature)|literary trope}} called anthimeria, and is typically used by using a noun as a verb (or 'verbing a noun'). [[Megan]], in conversation with [[Cueball]], similarly creates new meanings from existing words: firstly, she uses the {{w|adjective}} "legit" (a slang abbreviation of "legitimate") as an {{w|adverb}} to mean "legitimately"; secondly, she uses the {{w|noun}} "adverb" as a verb meaning "to turn a non-adverb into an adverb"; and thirdly, she uses the {{w|noun phrase}} "language nerd" as an adjective. All three are used in the past tense.

Megan uses the words "verbed" and "adjectived" without any comment, implying that the acts of "verbing" the nouns "verb" and "adjective" are so natural and long-established that they are unremarkable (although the fact that "adjectived" came after "verbed" may also have something to do with the latter's non-mention), even if grammatical purists might decry such usage. An example of a change of parts of speech that is widely accepted is the {{w|gerund}}, which is nothing more than the use of a verb or verb-phrase as a noun; for instance, "I enjoy '''reading'''," and "the best thing for your health is '''not smoking'''".

Added humor is gained by the self-referential nature of Megan's sentence. She uses fluid parts of speech, and also refers to that very same use, in one sentence.

The title text, "Not to go all sentence fragment on you," is an implicitly self-referential sentence fragment, containing neither an explicit subject nor a predicate. It can be converted into a full sentence by rephrasing it something like, "I do not mean to go all sentence fragment on you, but..." It is also funnier because, as well as being ''self''-referential, it also refers to the main comic by adjectiving the noun-phrase "sentence fragment".

==Transcript==

1508: Operating Systems

| titletext = One of the survivors, poking around in the ruins with the point of a spear, uncovers a singed photo of Richard Stallman. They stare in silence. "This," one of them finally says, "This is a man who BELIEVED in something."
}}

==Explanation==
In this comic, [[Randall]] gives an {{w|Gantt chart|overview}} of the past, present and (speculatively) future of the {{w|operating system}}s running in his house at any given time. Notably, because Randall is fascinated by technology, he has had more than one OS running in his household since the mid '90's. The timeline tracks how Operating Systems have come and gone over the years, and the gradual shift from desktop Operating Systems to mobile can be observed. Beyond the present day, we see some of Randall's humorous predictions as to which technologies and companies will dominate the Operating System landscape in the future.

It may be that the OS that is closest to the time-line is also the one he mainly uses during these extended periods.

Previous and current systems:
*{{w|MS-DOS}} (Microsoft Disk Operating System): The default, command-line-based OS on most IBM PC-compatible computers. Early versions of {{w|Microsoft Windows}} operated as shells on top of MS-DOS rather than stand-alone OSes in their own right, which may explain part of the overlap in those two bars.
*Apple's {{w|Mac OS}} (Macintosh Operating System): The OS of Apple's Macintosh line of computers. Randall's bar indicates that he stopped using Macs in 2001, after Mac OS had been superseded by the new and then-buggy {{w|Mac OS X}}.
*{{w|Linux}}: A [https://www.gnu.org/philosophy/free-sw.html free and open source] Unix-like OS. Randall's bar indicates that he likely used it on one or two PCs starting from 1999 while still using Windows on other PCs, or perhaps was dual-booting one or more PCs with Windows, until abandoning Windows in 2007 to use Linux full-time. This timing coincides with the release of Microsoft's controversial {{w|Windows Vista}} and the advent of more user-friendly Linux distributions.
*{{w|OS X}} (Macintosh Operating System v10): The successor OS of Apple's Macintosh line of computers. Although it was sometimes marketed as merely the 10th version of the earlier Mac OS, it was largely a new product. The bar indicates Randall's renewed use of Macintosh computers in 2009 after the OS had matured and Macs had transitioned to Intel processors.
*{{w|Android (operating system)|Android}}: The upper layers of the OS running on Android phones and tablets, above the Linux {{w|Kernel (operating system)|kernel}}. Randall is indicating that he has at least one of these devices.
*Apple's {{w|iOS}}: The OS of {{w|iPhone}}, {{w|iPad}}, {{w|iPad mini}}, {{w|iPad Air}}, {{w|iPod Touch}} and {{w|Apple TV}}. Randall is indicating that he also has at least one of these devices.

His predictions for the future include:
*2018: That {{w|OS X}} and {{w|iOS}} will merge. There is frequent speculation on technology blogs as to whether or not this merging will come to pass in the future. The two OSes have a common origin, share a lot of software, and are maintained by the same company that would benefit from the efficiency of maintaining a single unified OS. Opposing this is the fact that interaction patterns are very different between traditional computers and tablets/phones and a one-size-fits-both solution may not be feasible (as proven by {{w|Windows 8|Microsoft's disastrous attempt at such}}), the fact that iOS and OS X (now macOS) run on different processor architectures (Mac OS X/OS X/macOS formerly ran on {{w|PowerPC}} processors and now runs on {{w|x86}}-family processors, while iOS runs on {{w|ARM architecture|ARM}} processors), and the fact that Apple spends some time in each of its recent keynotes mocking computers like the Microsoft Surface Pro which use both standard computer and touch control. However, that said, with the release of {{w|iOS 11}}, the iPad version of iOS has diverged greatly from the iPhone version and is now converging rapidly with macOS, so a merger between macOS and ''part'' of iOS might not be too far off...
*2019: That an operating system designed with and for {{w|JavaScript}} will become attractive, perhaps along the lines of [http://node-os.com/ NodeOS] and/or [http://runtimejs.org/ Runtime.js].
*2022: That there'll be an OS based on the {{w|Tinder (application)|Tinder}} dating app.
*2024: That there'll be an OS from {{w|Nest Labs}}, presumably oriented towards home automation and the {{w|Internet of things}}.
*2029: That {{w|Elon Musk}} will come up with an operating system.
*2030: That {{w|Disk operating system|DOS}} would make a comeback, but only in an ironic fashion (maybe because there would be no more disks left for it to operate from).
*2034: That Randall will be deploying an [http://geneticliteracyproject.org/2014/07/genetically-engineered-red-blood-cells-could-be-drug-delivery-drones/ autonomous drug-delivery drone] in his body.
*2042: Human civilization comes to a fiery end, maybe due to some unholy combination of the above innovations. Another possible explanation is that human civilization will be wiped out by an artificial super-intelligence, superior to human intelligence, as Elon Musk, Ray Kurzweil, Bill Gates and many tech pundits foresee that 2045 will be the year to see such technology becoming real, and as Elon Musk, Bill Gates and many other tech pundits fear that it will be the extinction of all life on earth, as explained [http://waitbutwhy.com/2015/01/artificial-intelligence-revolution-2.html on this page].
*2059: At this time his operating system will be {{w|GNU}}/{{w|Hurd}}. This infamously and perennially late [http://www.gnu.org/software/hurd/hurd.html GNU/Hurd] OS will finally make it in to Randall's home after human civilization has been wiped out. The joke is that GNU/Hurd began to be developed in 1990, and while it was expected to be released in a relatively short time, even now only unstable builds have been released. So Randall is saying that he will finally run it in his house a decade or two after the end of civilization. GNU/Hurd will presumably have an advantage as humanity rebuilds civilization due to the widespread availability of its code and development tools, and perhaps also because of Stallman's depth of belief, based on the title text. Alternatively, GNU/Hurd might be finished by the same force that finished humankind, for instance {{w|Skynet (Terminator)|Skynet}}, in case of {{w|Cybernetic revolt|AI Apocalypse}}. (Interestingly, although still far from completion, [http://git.savannah.gnu.org/cgit/hurd/hurd.git/commit/?id=b8ffab7c38f3ede424b8a07553d6ee6b16abb85b a new version of GNU/Hurd] was released less than a week after this comic.)

The title text refers to {{w|Richard Stallman}}, the founder of the {{w|Free Software movement}} and the GNU and Hurd projects. A survivor of the fire that ended the human civilization has uncovered a slightly burned ({{w|Singe|singed}}) picture of him. Those gathered can see, either directly from the picture or because they already know of Stallman, that this was a man that really believed in something. In this case it was ''free software''. Inspired by his image, they rebuild their lost civilization and finish Hurd development.

The GNU/Hurd reference might also be a pun, as in a "herd" of {{w|Wildebeest|Gnus}} "running" in his living room, as wild animals reclaim the Earth after the end of human civilization.

GNU is a collection of free software utilities, particularly the system utilities used with the Linux Kernel to form the Linux operating system (often called GNU/Linux by those who wish to emphasize the contribution of the GNU project). Hurd is an operating system kernel designed as part of GNU project that could be used in place of the Linux kernel to produce a complete GNU operating system. Hurd has a microkernel architecture, which has many perceived advantages over Linux's monolithic kernel, and is thought by many to be technically superior, despite its low adoption rate compared to the Linux kernel.

Randall has made several comics about free software and also about Stallman. See this list of [[:Category:Comics featuring Richard Stallman|comics featuring Richard Stallman]]. Most of these are also about free software in some form.

| titletext = Stanford sleep researcher William Dement said that after 50 years of studying sleep, the only really solid explanation he knows for why we do it is 'because we get sleepy'.
}}

==Explanation==
[[Cueball]] claims that humans are driven by their curiosity, which is never-ending. [[Megan]] responds by noting that everyone spends approximately eight hours per day in an unconscious state of {{w|sleep}}, but no one has yet pinned down the biological purpose of sleep. Despite this obvious mystery, most people aren't "losing sleep over it." This implies that Cueball's observed curiosity has a perceptible and proximate limit.

This is not to suggest that scientists ''aren't'' researching sleep; scientists frequently conduct {{w|Sleep study|sleep studies}} — we just haven't found any satisfactory answers yet. Some popular hypotheses are to allow the brain a period to consolidate memories and to give the body a chance to repair itself.

The title text quotes {{w|William Dement}}: people sleep "because we get sleepy." ([http://ngm.nationalgeographic.com/2010/05/sleep/max-text Secrets of sleep]). This of course is dodging the underlying issue. That this non-explanation is the best answer that a leading sleep researcher can provide, shows how little anyone knows about the subject. This may be an oblique reference to the [[:wikt:dormitive principle|dormitive principle]] of the French playwright Molière, who created a satirical character who claimed to have discovered the answer to a popular question: The reason opium makes someone sleepy, said the character, a doctor, was that it contained a "dormitive principle" (i.e., something that makes someone sleepy).

In [[203: Hallucinations]], Randall expressed similar surprise at the lack of interest in the nature of sleep.

The phrase "and nobody knows why" is commonly appended to urban legends, as in [http://www.snopes.com/critters/wild/duckecho.asp A duck's quack doesn't echo, and no one knows why]. The implication is that something mysterious is going on and scientists are puzzled. [[1186: Bumblebees]] is another "nobody knows why" example.

1408: March of the Penguins

{{comic
| number = 1408
| date = August 15, 2014
| title = March of the Penguins
| image = march_of_the_penguins.png
| titletext = You ARE getting older, though.
}}

==Explanation==
Several of the xkcd comics outline ways to [[:Category:Comics to make one feel old|make people feel older]] by referencing various pieces of popular culture which feel ingrained and "recent", and revealing the time that has elapsed since their release to be longer than expected (for instance, [[1393: Timeghost]] and [[891: Movie Ages]]).

This appears to be what [[Black Hat]] is doing as he walks in on [[Megan]] to announce that all the penguins from a 2005 documentary ''{{w|March of the Penguins}}'' about {{w|emperor penguins}} are dead. Megan is familiar with these sorts of antics and assumes Black Hat is indicating that the film is so old that the lifespan of emperor penguins is less than the time since the documentary was released. Frustrated, Megan simply acknowledges Black Hat's statement by agreeing that everyone is aging. Black Hat, however, reveals that he is not trying to make her feel old, because the penguins were all alive "last night" and all died in one instance since then and thus not from old age.

His announcement that he is "trying to apologize" creates the obvious inference that he caused the penguins to be killed (either intentionally or by mistake). This gives the situation a much darker tone; especially since Black Hat likely is not truly apologizing, as he is very unapologetic in his [[72: Classhole|"classhole"]] tendencies, and just wish to mess even further with Megan.

Emperor penguins actually live about 20 years on average, so presumably, barring any intervention by Black Hat, most of the younger penguins and many of the older penguins in the movie are still alive as of the time of release of this comic in 2014 nine years after the documentary was released.

The title text emphasizes that whatever the penguins' fate, we do get and are getting older.{{Citation needed}} This is presented as a last jab by Black Hat as he departs just to make Megan feel a bit worse. So in the end this comic did try to make the reader feel older.

This also presents an alternative take on the entire comic: Black Hat came in to make Megan feel old because all the penguins of the movie is actually naturally dead of old age, predators, disease etc. And if she likes the movie, she would not have realized that it was almost nine years ago she saw it, and the feel old by realizing how time passed. But she ruins Black Hat's moment by realizing what he is trying to do. (As opposed to what he manages in a comic like [[493: Actuarial]], that might also make you feel old). So instead of saying ''yeah you got me'', he quickly invents a story that they actually all lived last night, and then takes the blame for killing them just to shock Megan.

This fits with the title text, as he then manages to make a jab at how old Megan should feel anyway. This is supported also by the fact, that although the movie was released in January 2005, the team behind it had filmed the penguins for 13 month prior, so some of the penguins in the movie must have been adult back in 2003. So it is not only nine but rather eleven years ago and several of the penguins in the movie must have died of natural causes prior to this comic, although not all! But Black Hat's fake statement indicates that all of them were still alive yesterday.

The worst part of this is that it seems like Megan believes him, but she of course also knows him to be a classhole (see for instance [[596: Latitude]]) and might believe him capable of locating and exterminating all the penguins from the movie over night...

510: Egg Drop Failure

| title = Egg Drop Failure
| image = egg_drop_failure.png
| titletext = I hear my brother Ricky won his school's egg drop by leaving the egg inside the hen.
}}

==Explanation==
A common competition for {{w|Primary school|school}}-age children (e.g. in {{w|Science fair|science fairs}} or {{w|Summer camp|summer camps}}) is the '{{w|Egg drop competition|egg drop}}': each team is given an unbroken {{w|Egg|egg}} (either raw or boiled, and usually of a {{w|Chicken|chicken}}), and may be provided with an assortment of materials, e.g. newspaper, {{w|Ice pop|popsicle}} sticks, string, tape, etc. The challenge is to build a contraption that will allow the egg to be dropped from some specified height onto a hard surface without breaking. In some competitions, the rules permit the contraption to be constructed from any available materials; other times, it is limited to only the materials that have been provided. Scoring varies wildly - common elements are speed of assembly, mass of the contraption, creativity of design (as determined by judging or voting), and/or accuracy of landing within a target area - but one near-universal rule is disqualification if the egg's {{w|Eggshell|shell}} is broken.

In the comic, the competitor fails, not because of any flaw in his design, but because the egg hatches unexpectedly during the fall. In reality, the hatching process usually takes many hours<ref>[https://modernfarmer.com/2015/04/how-to-incubate-chicken-eggs/ "How to Incubate Chicken Eggs"]. ''Modern Farmer''. April 9, 2015. [https://web.archive.org/web/20200102164503/https://modernfarmer.com/2015/04/how-to-incubate-chicken-eggs/ Archived] from the original on January 2, 2020. Retrieved January 30, 2020. "It is normal at this point for the chick to rest for six to 12 hours while its lungs adjust before continuing to hatch."</ref><ref>[https://www.backyardchickens.com/articles/step-by-step-guide-to-assisted-hatching.64660/ "Step by Step Guide to ASSISTED Hatching"]. ''BackYard Chickens''. March 11, 2017. Retrieved January 30, 2020. "Some [chicks] pip internally and fully hatch in hours while others will be 24 hours or more."</ref> — much longer than the few seconds of a typical egg drop; furthermore, the newborn {{w|Chick|chick}} cannot fly immediately. However, if it were to magically happen as in the comic, then the competitor would be disqualified because the egg technically broke when the chick hatched from it.

The title text suggests an alternate strategy, one Randall hears was successful in real life: select for your egg one that has not yet been laid. The {{w|Hen|hen}} provides both active lift with her wings and significant padding with her body and feathers, thus nearly guaranteeing that the egg will survive the fall. But the chicken may not be permitted in some contests if it is not one of the allowed materials. And even if it were, a chicken might be heavier than the usual contraptions of newspaper and string,{{Citation needed}} so it might lose anyway if weight is one of the scoring criteria.

}}

==Explanation==
{{incomplete|Created by a BEE PROVING THE HAIRY BALL THEOREM (WITH A COX-ZUCKER MACHINE) - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
[[Megan]] has had a very unfortunate experience of falling into a garbage can and being repeatedly stung by wasps. [[Cueball]] expresses an appropriate amount of horror about it. However, Megan seeks to downplay this experience by saying "I shouldn't complain" and that she's "lucky" it wasn't worse. This has become a {{tvtropes|AppealToWorseProblems|habit in Western culture}}, like comparing minor issues to "kids starving in Africa" or war-torn countries, notably Ukraine (this comic was published during the {{w|2022_Russian_invasion_of_Ukraine|Russian invasion of Ukraine}} starting in February 2022 and was ongoing when this comic came out on March 7).

Humans have a tendency to re-calibrate their mental scales to place their actual experience in the center. Cueball, who has never experienced being trapped for hours with stinging insects, rates this in comparison to not being trapped at all. Megan, however, rates it in comparison to other uncomfortable places a person could be stuck.

The title text explains how Megan came into such a mess. A tennis ball used in a clothes dryer got stuck in the exhaust vent, and was shot out of the house through the exhaust vents hole in the wall. Then it hit the wasp nest and ricocheted over on Megan knocking her off the ladder she was standing on. Since she was close to the nest, she may actually have been up on the ladder in order to see if she could remove the nest. The fall from the ladder made her end up in the trash can where she could not get out. The angry wasps began stinging her legs. This continued for two hours.

In the title text, Megan continues to downplay her experience even though it was very painful. She says that the wasp nest was of the type {{w|Dolichovespula maculata|bald-faced hornets}}.

The {{w|Schmidt sting pain index}} is a scale developed by entomologist {{w|Justin O. Schmidt}} to rank the relative pain caused by different stinging insects. This scale ranges from 0 (for stings that are completely ineffective) to 4, which denotes torturous and nearly incapacitating pain (originally, Schmidt only classed one species as a 4, but two additional species have since been added at this level). Megan says her stings were a {{w|Schmidt_sting_pain_index#Pain_Level_2|2 on the scale}}, which denotes "familiar" pain, comparable to that of the common {{w|Western Honey Bee}}. Most people would find that experience incredibly painful, particularly since she endured multiple stings over a long period of time, but Megan points out that there exist insects with more painful stings.

Megan concludes that she'd been lucky, based on the argument that she theoretically could have endured something worse than she did. The joke, of course, is that by almost any subjective standard, her experience was deeply unluckly.

She also further downplays the situation by focusing attention on the sting pain index instead of the sting lethal capacity, described by the [https://pubmed.ncbi.nlm.nih.gov/3810666/ author of the pain index]. The two are not necessarily equivalent. Let's assume that all insects in the colony affected stung Megan at least once over her two hour ordeal. A colony capable of sustaining an attack over two hours would probably be at least as large as the typical [https://www.rescue.com/latest-buzz/outdoor-pests/bald-faced-bully/#:~:text=Bald%2Dfaced%20hornet%20nests%20often,hornet%20workers%20enter%20and%20exit. maximum size for a bald-faced hornet nest]. Such an attack might (depending on number of attackers and the species of wasp) deliver enough venom to kill 84 kg (185 pounds) worth of mice (or human?). Given such an attack, Megan would probably not be standing around in routine conversation, casually discussing the incident. She would far more likely be in a hospital bed, and in a [https://pubmed.ncbi.nlm.nih.gov/32252275/ gruesome fight for her life].

2595: Advanced Techniques

| titletext = A blow from Emmy's Cutlass of Variations will transport the dragon to a corresponding symmetric position in the Noetherworld.
}}

==Explanation==
{{incomplete|Created by AN EULISH CLAUSS- Please slay the CORRECT dragon when editing this page. Do NOT travel to the Noetherworld. Do NOT pass Go. Please collect the correct sedenion.}}
In typical [[Miss Lenhart]] fashion, she is teaching a mathematics class where she outlines a process by which a mathematical result is achieved through steps which sound suspiciously like magical {{w|Role-playing game|RPG}} logic. She includes both a dragon and arrows to slay it.

One of her students asks if this is a metaphor for the technique, but her rather tetchy reply "Does this look like English class?!" seems to imply that she literally means that dragons and arrows will be employed in the resolution of the problem. It is also clear from the slide she is pointing at that she has drawn a dragon and a man with a bow that is aiming an arrow at the dragon. Whilst metaphor is an important part of many languages, and so is definitely taught in language classes, it is not usually used in math classes.

The caption beneath the comic states that this approach describes "All advanced math techniques." This could be a reference to the now-common approach in higher mathematics in which a problem is transformed into another domain where it is easier to solve, then transformed back. For instance, in {{w|Fourier analysis}}, commonly used for analyzing the behavior of signals or dynamical systems, a problem can be transformed from the time domain to the frequency domain, solved, and then transformed back again. A (much) more complex example is Andrew {{w|Wiles's proof of Fermat's Last Theorem}}, which uses {{w|modularity theorem|modularity lifting}} to transform the problem. Here Miss Lenhart says she will transform a math problem into an actual dragon, slay it, and transform the corpse back into mathematics.

An alternative view is that Randall is referring to {{w|Arthur C. Clarke}}'s {{W|Clarke's three laws|third law}} that ''Any sufficiently advanced technology is indistinguishable from magic'', as re-framed for mathematics. What [[Randall]] would be implying is that all advanced math techniques look like magic to non-mathematicians. (Another advanced and somewhat magical math technique is deployed by Miss Lenhart in [[1724: Proofs]].)

Invocations are a common classification for spoken or vocalized types of spell. In the logic Miss Lenhart used, 'invoking' Gauss's operator may refer to casting a magical spell with verbal components (such as [https://roll20.net/compendium/dnd5e/True%20Polymorph True Polymorph]). The operator is presumably named after the famous German mathematician {{w|Carl Friedrich Gauss}}. There is nothing on Wikipedia called Gauss's operator, but there is both {{w|Gauss's law}} and the {{w|Gauss–Kuzmin–Wirsing operator}}. As neither can transform an equation into a dragon,{{Citation needed}} it's clear Randall is making a joke.

Slaying the dragon with Hilbert's arrow indicates that the arrow has some magical properties. The arrow is presumably named after {{w|David Hilbert}}, known for many mathematical developments including {{w|Hilbert's problems}} and {{w|Hilbert spaces}}. A Hilbert space converts subsets of an infinite vector space into a complete metric space, allowing the use of linear algebra and calculus methods which might otherwise be applicable only to finite Euclidean spaces. Vectors could be compared with an arrow. Magical arrows are frequently used to slay dragons in myth and role-playing games. Magical items in RPGs such as {{w|Dungeons & Dragons}} are often named after a creator or famous user; hence, a magical "Arrow of Hilbert" might traverse infinite spaces or affect targets for which one or more stats are effectively infinite.

There is in fact a class of {{w|Dragon curve}}s, which do have the sort of S-shape shown on the whiteboard, but they have no connection to Gauss's operator, and are not actual dragons that need slaying.

The title text contains two puns and a reference. The phrase "{{w|Cutlass}} of Variations" is a pun on the mathematical technique called "{{w|Calculus of variations}}". The word "Noetherworld" is a pun on "{{w|underworld|netherworld}}". The reference is to the mathematician {{w|Emmy Noether}}, a giant in the field of abstract algebra which, through more of Ms. Lenhart’s questionable transformations, may become an actual giant in a field of abstract algae bras. Furthermore, {{w|Noether's Theorem}} is used in the Calculus of Variations. She was previously referenced as one of many important women in science back in [[896: Marie Curie]].

Above the drawings there are three and below two rows of unreadable text and equations.]

2598: Graphic Designers

| titletext = They might make it past that first line of defense. For the second, you'll need some picture frames, a level, and a protractor that can do increments of less than a degree.
}}

==Explanation==
{{incomplete|Created by the fiendish HEX CODE #D3D3D3 AND FRIENDS - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
[[Cueball]] is inviting [[Knit Cap]] into his newly repainted residence. Knit Cap is a {{w|graphic designer}} and he simply can't enter because of the [[#Colors|color scheme]] used. The caption explains that if you paint each wall a slightly different shade of off-white, a graphic designer will be so repulsed that they are physically unable to enter the room. This is analogous with a specific bit of vampire lore: {{w|Vampires}} cannot {{w|Vampire#Protection|enter a dwelling uninvited}}.

Being presented with visual information that is ''just not quite right'' is known to cause feelings of unease and revulsion, particularly when presented with CGI human faces, a concept known as the {{w|uncanny valley}}.

In the title text, it mentions a contingency against the designer managing to actually overcome this disgust. In this case, Cueball sets up a second way to troll his graphic designer friend using some picture frames, a {{w|Level (instrument)|level}}, and a {{w|protractor}} that can measure increments of less than a degree. Cueball can then skew his picture frames by an extremely small amount, noticeable only to the designer friend, to disgust him even further — similar to the effect of [[1015: Kerning|bad kerning]]. This could thus be applied like the use of {{w|Christian cross|crosses}} or {{w|Garlic|garlic}}, which vampires are famously repulsed by.

Although the window ledges are slightly inclined, falling subtly from left to right, it is unlikely this is a deliberate aspect of the room so much as a side-effect of Randall's imprecise stick-figure drawing style.

===Colors===
True to the comic's joke, [[Randall]] has actually colored each segment of the comic differently to each other, even though normal persons would just perceive all walls as slightly gray (off-white).
The hexadecimal color codes are:
* Floor: #FFFFFF [[https://www.colorhexa.com/ffffff White]]
* Ceiling: #F3F7F8 [[https://www.colorhexa.com/f3f7f8 Light Grayish Cyan]]
* Walls (left-to-right)
** #F2F0EE [[https://www.colorhexa.com/f2f0ee Light Grayish Orange]]
** #F3F4F2 [[https://www.colorhexa.com/f3f4f2 Light Grayish Green]]
** #F2F3F4 [[https://www.colorhexa.com/f2f3f4 Light Grayish Blue]]
** #F3F2F4 [[https://www.colorhexa.com/f3f2f4 Light Grayish Violet]]
* Door: #F1F3F1 [[https://www.colorhexa.com/f1f3f1 Light Grayish Lime Green]]
* Left window frame/ledge: #F2EEF2 [[https://www.colorhexa.com/f2eef2 Light Grayish Magenta]]
* Right window frame/ledge: #F3F3F1 [[https://www.colorhexa.com/f3f3f1 Light Grayish Yellow]]
* Box seat top: #EEF1EC [[https://www.colorhexa.com/eef1ec Light Grayish Green]]
* Box seat front: #F2EEF0 [[https://www.colorhexa.com/f2eef0 Light Grayish Pink]]
* Rug outer ring: #F0F2F1 [[https://www.colorhexa.com/f0f2f1 Light Grayish Cyan - Lime Green]]
* Rug inner panel: #F0EFF1 [[https://www.colorhexa.com/f0eff1 Light Grayish Violet]]

Whilst this subtle difference may be undetectable to humans without a graphic design qualification, it can be made clearer by increasing the saturation value of the image, as shown in this [https://i.imgur.com/gMpmJlp.png rendering with an exaggerated color saturation].

==Transcript==
:[Cueball stands in a lightly adorned room of a house, facing an open doorway. Each surface is painted an almost imperceptibly different shade of off-white, except the floor which is white.

Knit Cap stands in the open doorway, as if about to enter the house, one foot at the threshold, but not on the floor inside. Cueball is reaching towards the doorway, inviting Knit Cap to enter.]

2600: Rejected Question Categories

}}

==Explanation==
{{incomplete|Created by a HANGING ROCK OF MASS DESTRUCTION LAUNCHED AT A VOLCANO BY HOT SINGLES IN YOUR AREA- Please change this comment when editing this page. Do NOT delete this tag too soon.}}
[[Randall]] recently announced, in [[2575: What If? 2]], that he is publishing a new ''[[what if?]]'' book based on reader-submitted questions. This comic is another [[:Category:Book promotion|promotion]] of the book, and the entire comic is a link to his [https://xkcd.com/what-if-2/ what if? 2] page on xkcd.

This comic shows the [[#Question categories|categories of questions]] he claims to have received, but rejected to use in his book, giving an example question for each category. In typical xkcd fashion, these begin out by being plausible, although often unlikely to have been submitted as a ''what if?'' question, moving in to more and more absurd types of questions, especially with the last question, that appears to be a combination of all previous categories and is therefore marked "?????"

The title text refers to the launch date of the book September 13, rendered in the American style 9/13. This format can be confusing to non-Americans, although usually not when the date is larger than 12, since it would then appear to reference the 9th day of the 13th month. This "13th month" was, however, referenced in the first comic about the book: [[2575: What If? 2]]. See also Randall's take on the date format, {{w|ISO 8601}}, in [[1179: ISO 8601]].

Randall then continues the title text by referencing the second to last category with vague ominous questions. The example question here asks if there is need to worry about spiders after Tuesday. So Randall notes that the release date, 5.5 months after the release of this comic, is of course assuming anyone will survive past next Tuesday (2022-04-05).

Tuesday has been notably referenced in [[277: Long Light]], [[564: Crossbows]], [[1099: Tuesdays]] and most notably in [[1245: 10-Day Forecast]], where it seems that the last day ever will be a Tuesday. Tuesday is the second day of the week, and notably, the Tuesday of the week following the publication of this cartoon (April 5th, 2022) was the Day of the Spiders.

==Question categories==
{| class="wikitable"
|'''Category'''
|'''Question'''
|'''Explanation'''
|-
| People cheating on homework
| What if I made a pendulum by hanging a rock on a 2.75 meter string? What would its period be in seconds? (Show your work!)
| This appears to be a physics student trying to get out of doing their work by presenting the question for Randall to answer in ''What If'' (which is a common occurrence on question-and-answer sites such as Stack Overflow). Most school homework requires the student to "show their work", i.e. write out their process of solving the question. Making students show their work serves two purposes: it allows students to score partial credit on an incorrect answer if they show the right methodology and basic understanding even if they make a wrong turn along the way; it also prevents students from simply cheating by looking up the right answer without showing how they got that answer — the student including this caveat in their email is a giveaway as to their tactic (along with the boring nature of their inquiry).
|-
| Medical advice
| What if you got a scratch and the next day your hand looked like this [''📎 attachment'']? Should you see a doctor or what?
| Randall is not a physician, is not qualified to give medical advice, and will not answer medical questions. This was a problem on early Wikipedia which, for a time, required all articles covering medical topics to point to a {{w|WP:MEDICAL|Medical Disclaimer}}. This was also an issue covered in the 1st ''what if?'' book, under Weird and Worrying Questions from the Inbox, where a reader asks about the effects of a toxin on the excretory system. If your body is not behaving in the way you expect, consulting with a medical professional is, in general, a good idea.
|-
| Personal
| Why don't the squirrels in my yard like me???
| Randall has no way of knowing why the wildlife in a given area dislike a specific person, especially if this hints at a specific animosity/belligerence and not just general avoidance of humans as a perceived threat. These kind of questions are common on sites like reddit, and are usually covered by general explanation of animal behaviors unless the asker supplies more information in the comments. However, the choice of squirrels are likely not random since [[:Category:Squirrels|Squirrels]] are a recurring theme on xkcd and has often been [https://www.explainxkcd.com/wiki/index.php/Category:Squirrels#Uses_in_other_xkcd_media: used in what if?] (sometimes as {{what if|105|placeholder}} for a potentially horrible image).
|-
| Spam
| Do you want to meet lonely singles in your area tonight?
| This is a common online popup advertisement and is generally considered undesirable. An unavoidable side effect of Randall having an email address published where the public can find it is that spammers have just as much access to it. Most people do not respond to spam emails, and Randall is no exception.
|-
| Phishing
| Have you recently been the victim of phishing? To check, log in to your account by clicking here.
| Again, because Randall's What-If email is publicly available, phishers have access to it and can probe the recipient for information. Randall is experienced enough to recognize a phishing attempt and ignore it. This type of phishing scam, in which the scammer requests your personal data for the purported purpose of checking if it has been "stolen" thereby "stealing" it himself, has become more common as people have become aware of phishing, and phishers have thus embraced the possibility of exploiting a new niche in the layers of naivete.
|-
| Requests for help with a crime
| Using modern science, what would be the fastest way to get through this bank vault door? [''📎'' blueprints]
| No, Randall is ''not'' going to help a criminal commit breaking and entering or robbery, thank you very much. A common problem with heist movies is that they show a believable{{Citation needed}} method for breaking in to a vault which people then try to replicate in real life. Such movies often portray an expert in some other field being "smart enough" to craft the plan, sometimes unwittingly.
|-
| Unanswerable
| Why am I me and not someone else
| There is a lot in this question that could be unpacked, and Randall doesn't want to touch on any of it.

At face value the question is asking about {{w|Philosophy of mind}}, a branch of philosophy with many questions that are unanswerable due to our own imperfect understanding of mind. The asker is inquiring as to what process is responsible for designating that their consciousness be tied to the body in which they currently reside, as opposed to another body presumed to have consciousness; furthermore, they likely wish to know the mechanics behind how this process works. There is as yet insufficient data for a meaningful answer.

It's also quite possible the asker is feeling melancholic and unsatisfied with their life. Randall doesn't feel qualified to try diagnosing or treating someone's existential depression.
|-
| Vague
| What is going to happen? (Be specific)
| Some humor is derived from the request for specificity in the question, which completely lacks any sort of specificity of its own.
|-
| Vague and ominous
| Will I have to start worrying about spiders after Tuesday?
| This implies some event that occurs on a (possibly next?) Tuesday. This event may relate to spiders in some way, and cause those who do not currently worry about spiders to do so. If you do not currently worry about spiders, this question does not give enough specifics for Randall to intelligently answer whether or not you should start.
Possibly a [[:Category:Red Spiders|red spiders]] reference. Could also be a reference to [[1688: Map Age Guide]] where some dangerous event involving spiders is set to happen in 2022.
|-
| ?????
| Hi, we're lonely singles in your area, and we're wondering what would happen if we shot a nuclear bomb into a volcano! Click here to log in and tell us ...
| If nothing else, this entry is clearly made up by Randall, as it appears to be a combination of as many prior categories as he has room for, specifically Spam, Phishing, and an already-answered question, before getting cut off by the bottom of the panel.

"Would it be possible to stop a volcano eruption by placing a bomb (thermobaric or nuclear) underneath the surface?" was a question featured in the first ''what if'' book. Randall answered with an emphatic "No!"

[[Hairbun]] hands [[Megan]] a linguistics degree, and informs her she is now "in charge of" the word '{{wiktionary|bassoon}}.' Watching this, [[Ponytail]] and [[Cueball]] compare the words they were assigned when ''they'' got their linguistics degrees, '{{wiktionary|jackalope}}' and '{{wiktionary|slurp}}' respectively. Ponytail thinks bassoon is a cool word but thinks her own is better, whereas Cueball is not satisfied with his word. A bassoon is a woodwind musical instrument with a double reed, while a jackalope is a mythical creature, a ''jackrabbit'' crossed with an ''antelope''.

It is never clarified what being "in charge of" a word entails. It could mean being in charge of keeping track of the word, or having actual authority over the use of the word, which is unlikely as normally [[1726|language use cannot be dictated by a single person]]. Also, no specific university has control over all of linguistics as far as we know, so it would require every university capable of giving people linguistics degrees to co-operate, so nobody is assigned the same word. Any well-educated member of the linguistic community will know what is being suggested is impossible hence why they are the only ones aware of how important it is.

The title text merely furthers how seemingly random the entire situation is. The word "linguistics" was assigned to a "random student in Ohio who barely graduated and then went into automotive marketing", who we can assume isn't very important to the field of linguistics.{{Citation needed}} But this means that no one is actually taking care of this important word, since it must be assumed that the student is no longer interested in linguistics.

The idea of individuals having a guardianship of an idea or concept has appeared in science fiction. For example, in ''{{w|Fahrenheit 451}}'' characters have memorised books to save them from book-burning and... spoiler-stuff.

2604: Frankenstein Captcha

{{comic

| date = April 8, 2022
| title = Frankenstein Captcha

| titletext = The distinction between a ship and a boat is a line drawn in water.
}}

==Explanation==
{{incomplete|Created by a CAPTCHA RATED ARGH-Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic strip is a play on the meanings (and misunderstanding) of the name "Frankenstein". ''{{w|Frankenstein; or, the Modern Prometheus}}'' is an 1818 novel by Mary Shelley about a medical student named Victor Frankenstein who creates an artificial life-form. The man he creates once describes himself as "the Adam of [Frankenstein's] labour" in the book, and strictly speaking is properly known as "Frankenstein's ''monster''" (or perhaps "creation" or "son"), but is often erroneously called "Frankenstein" himself. This has been fertile ground for many, many debates about whether the monster could also properly be called "Frankenstein," either as a family name, an honorific, or simply because it's more recognizable and convenient. Randall has weighed in on the debate himself in a previous comic, [[1589: Frankenstein]].

The CAPTCHA shown in the comic instructs the user to select all tiles containing Frankenstein. The tiles include both a reanimated corpse resembling Frankenstein's monster and a scientist yelling, [https://www.youtube.com/watch?v=1qNeGSJaQ9Q "It's alive!”] who is clearly intended to be Victor Frankenstein. The problem arises from the contrast between various definitions of the term Frankenstein. Going just off the book's text, the monster has no name, so the correct answer to the CAPTCHA is just the left square of the third row. However, the character depicted there is clearly ''Henry'' Frankenstein from the famous {{w|Frankenstein (1931 film)|1931 film adaptation}} (Victor Frankenstein never said the words "it's alive!" in the book), and likewise the creature depicted is clearly inspired by {{w|Boris Karloff}}'s iconic portrayal in that film and its sequels. If the images are captured from that film, then all four of them could be said to be "containing (a subset of) ''Frankenstein'' (the 1931 film)".

Some CAPTCHAs - especially Google's widely spread reCAPTCHA - nowadays serve a dual purpose: (1) to separate human users from bots by way of intelligent interaction, and (2) to train a neural network, hence the "correct answer" to image recognition CAPTCHAs is not known ahead of time and is merely based on the most commonly-chosen tiles. Thus, a user who knows that "Frankenstein" refers only to the scientist would face this CAPTCHA with dread, uttering "Oh No" as they realize that they must select the tiles containing the monster, and possibly not even be allowed to select the tile containing the actual scientist Victor Frankenstein if they want to pass the CAPTCHA.

Alternatively, this comic strip with its "Oh No" caption could be referencing [[1897]], which would imply that someone had actually created a Frankenstein's monster which needs to be located as soon as possible.

Many of the other tiles appear to be pictures of entities that inspire similar pedantry. For example, there is a picture of a turtle (or possibly a tortoise, or a reference to the {{w|Voight-Kampff_machine|Voight-Kampff test}} used in a manner analogous to CAPTCHA), a ship (or possibly a boat), {{w|Link (The Legend of Zelda)|Link}} (the name given to each of several protagonists that appear across generations and timelines, throughout the ''{{w|Legend of Zelda}}'' video games, who many erroneously refer to as Zelda), a pond (or possibly a lake, a puddle, or a {{w|mirage}}), a squash or pumpkin (often subject to the ''fruit or vegetable'' debate), an erupting volcano (with lava, or is it magma?), and the planet Pluto (or is it a dwarf planet?). Other tiles seem to be inspired by images that commonly occur in actual captchas, like the STOP sign or the traffic light. However, at least some of these may also be meant to fall into the category of entities that inspire pedantry, for example: because traffic lights can also be called traffic signals or stoplights; many people thinking that the shape of a stop sign is a hexagon, not an octagon; and the definition of a sandwich (previously discussed as a “random semi-ironic obsession” in [[1835]]).

The title text refers to one of the methods used to distinguish a ship from a boat. When making a turn, if the vessel leans towards the inside of the turn circle then it is considered a boat, whereas if the vessel leans away from the turn circle it is considered a ship[https://www.youtube.com/watch?v=L1iM2CG5QQ8]. Since the vessel generates a wake as it moves, checking whether it is a boat or a ship can be done while it is literally drawing a line on the water (the wake). The phrase "a line drawn in water" is also an idiom for something ephemeral. Ironically, it has persisted for a long time and dates back at least to the early Buddhists. (e.g. [https://suttacentral.net/an3.132/en/sujato?layout=plain&reference=none&notes=asterisk&highlight=false&script=latin| AN 3.132] & [https://suttacentral.net/an7.74/en/sujato?layout=plain&reference=none&notes=asterisk&highlight=false&script=latin| AN 7.74]). The distinction between a ship and a boat is also unclear, having changed over time, with no universally accepted rule to {{w|Ship#Nomenclature|distinguish between the two}}. The title text is also a pun on the common idiom "drawing a line in the sand." The title text could also be referencing the image of a boat or ship that appears as one of the CAPTCHA tiles in the comic, where Randall has drawn a squiggly line often used in crude drawings to represent a waterline.

2605: Taylor Series

==Explanation==
{{incomplete|Created by THE MACLAURIN SERIES EVALUATED AT X PLUS EPSILON - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

In mathematics, a {{w|Taylor series}} {{w|Polynomial expansion|expansion}} is a {{w|polynomial}} {{w|power series}} approximation of a function[https://matheducators.stackexchange.com/a/10212] around a given point, composed of an infinite sum of the function's {{w|Derivative|derivatives}}, each both divided by successive {{w|Factorial|factorials}} and multiplied by the incrementally increasing {{w|Exponentiation|power}} of the distance from the given point. Such expansions usually continue without end. Beyond approximation of functions, Taylor series are also useful for deriving numerical approximations of {{w|Irrational number|irrational}} values, {{w|Machin-like formula|such as π}}, as well as {{w|Symbolic integration|symbolic}} forms to make functions easier to integrate or otherwise manipulate with calculus.[https://www.mathsisfun.com/algebra/taylor-series.html] However, because they involve difficult calculus operations, and can be annoyingly tedious to {{w|Numerical analysis|calculate by hand}}, they are often not loved by math students.[https://www.reddit.com/r/EngineeringStudents/comments/gbo8tm/taylor_series_can_fuck_off/]

[[Miss Lenhart]] appears to be teaching a class about how to use a Taylor series. She presumes her students want to keep learning about the series, in that they, "wish it would never end." She then says "Good news!" because the series does not end. The cartoon's humor is based on the contrast between wishing the series won't end, ordinarily desired of sequences of enjoyable events, and the infinite nature of the Taylor series, which is less likely appreciated by her students struggling to understand why the sums {{w|Convergent series|converge}} to their resulting value.

The title text is a reference to the common practice among physicists and engineers of abbreviating the Taylor series to only the first few terms, typically one or two, in order to simplify the mathematics of their models. The title text is also a pun on the use of the word "series" to refer to a television program. It symbolizes the terms of the mathematical series as a {{w|metaphor}} with a television season, suggesting that only the first term is useful. It makes fun of the common sentiment against bad {{w|screenwriting}} of a series by saying that, "The series should have been cancelled after the first season," replacing "season" with "term." (Notably, both "term" and "season" are used to refer to a stretch of time during which a program is airing—generally, a television or scholastic program, respectively.) Also note that US President {{w|Zachary Taylor}} died during his first term. In a way, his presidency was cancelled during his first term.

2607: Geiger Counter

| title = Geiger Counter
| image = geiger_counter.png
| titletext = At first I didn't get why they were warning me about all those birds sitting on the wire, but then I understood.
}}

==Explanation==
This comic is a simple {{w|pun}}. [[Cueball]] and [[Ponytail]] are standing in what looks to be a desert, and Cueball is holding a {{w|Geiger counter}} in his hand. Cueball remarks that he did not understand why he was asked to carry a Geiger counter, but that it then "clicked" with him.

Geiger counters are devices used to measure the amount of {{w|radiation}} in an area. When a particle of ionizing radiation hits the sensor of a Geiger counter, it will give off a distinct "clicking" noise. "Click" can also be a slang term for the {{w|Eureka effect}}, a sudden moment of understanding. The pun in this comic insinuates that Cueball realized why he was asked to bring the Geiger counter when it clicked, indicating radiation nearby. In radioactive areas, it is usually a good idea to carry around some sort of radiation detector for {{w|Radiation#Possible_damage_to_health_and_environment_from_certain_types_of_radiation|safety reasons}}.{{citation needed}}

This is likely a {{w|parody}} of a fairly well-known pun that takes advantage of a similar double meaning: "I wondered why the baseball was getting bigger. Then it hit me." Just as that pun uses "hit me" to mean both the action of the ball and to understand, this comic uses the "clicking" to mean both the action of the Geiger counter and to understand. A related variety of pun, told in the {{w|Narration#Third-person|third person}}, is the {{w|Tom Swifty}}.

The title text is also a pun, with the implication being the narrator "understood" once they "stood under" the birds that were perched on the wire (who may have then pooped on the narrator to bring them to their understanding [in the "realization" sense]).

2608: Family Reunion

{{comic
| number = 2608

| title = Family Reunion
| image = family_reunion.png
| titletext = Grandma says that because of differences in primate and feline lifespans, the cat is actually my 17,000,000th cousin 14,000,000 times removed.
}}

==Explanation==
{{incomplete|Created by THE PERSON WHOSE RELATIVE IS A CAT AND A HUMAN (WHOOPS) - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

Because all humans are descended from a {{w|Mitochondrial Eve|common ancestor}}, every human is, at some point, related to every other human, albeit distantly. Similarly, all life forms on Earth are presumed (with good reasons) to be descended from a single {{w|Most recent common ancestor|even more distant relative}} whose ultimate lineage {{w|Last universal common ancestor|became more relevant}} than any from its own 'cousins' at the time, and thus ''all'' life forms are distantly related. This makes every interaction with another life-form, technically, a family reunion, if not in the traditional sense.

The general English definition of a {{w|cousin}}, which is a person sharing an ancestor who is not a direct parent of either party, can be qualified by two numbers. There is the ''n''th-ness of the relationship (the fewest generations you need to go beyond one's parentage, "a first cousin" implies that a grandparent is the key link) - for example, [[Cueball|this Cueball's]] relation to [[White Hat]] is via a great-grandparent, whilst that with [[Hairbun]] is through a great-great-great-great-great-great-great-great-grandparent. A "removed" number is any difference in this number between the two individuals, such that a child of a direct cousin invokes a "once removed" relationship between the two (without individually qualifying who is the 'senior' generation, from whom the 'nth' count is determined). You would normally only qualify "first cousin" if this fact is considered important, and "zero times removed" would also be considered implicit.

As pointed out in the title text, cat lifespans (or, more importantly, inter-generational breeding cycles) are somewhat different from those of humans. Although they would have still been very similar immediately after the divergence from the appropriate most recent common ancestor (MRCA), the differences will have built up to a generational-count displacement of a similarly extreme nature. i.e. that while the shared ancestor is Cueball's 17-million-or-so-Great Grandparent, the cat is in turn the 31-million-or-so-Great Grandchild. Exactly how accurate, or even precise, Randall considers these numbers is unknown, but it is the kind of fact that we know he likes to research and use expert opinion for.

According to [https://www.quora.com/How-many-generations-of-human-beings-recognizably-the-same-as-us-have-there-been this Quora page], there have been about 13,000 generations of modern humans, so the people at this party would be quite closely related, all things considered.

[https://www.evogeneao.com/en/learn/tree-of-life The Evogeneao Tree of Life diagram] indicates that humans and cats diverged around 90 million years ago and humans and plants diverged around 1.8 billion years ago.

If we presume that generations of humans (including proto-humans, pre-humans, etc) since the divergence from cathood (including proto-cats, pre-cats, and the rest, back to the common ancestral form) have averaged around 5 years, then a 17 millionth cousin may be about right. Many of our (and cats') early ancestors will have necessarily been small burrowing mammals — to have been amongst the ones who survived the asteroid around 66 million years ago that killed off most of the dinosaurs — with contemporary equivalents having breeding cycles in terms of a year at the most. But we currently have a large feasible range of generational cycle (15-50 years, ''very'' roughly, with or without technical/social help or hinderances), that may have started to drag our long-term average upwards since at least the age of the early hominids, if not the age of our primate forebears or earlier.

To get a 50 billionth cousin from the potted plant, then the generations of (eventually) humans since we were of the same form as that time's ancestral plants (or vice-versa) would need to average two weeks. This is possible, but difficult to be precise about due to the lack of much of the required evidence in the known fossilized remains. Any reasonable estimate, however, should be heavily weighted towards generation spans common for unicellular eukaryotes, rather than the longer generations common for multicellular eukaryotes: the general consensus on the most recent common ancestor for of animals and plants identifies it as a unicellular eukaryote.
Given the above analysis of eukaryotes as cousins one wonders why Randal Monroe didn't include that every lack of gathering is also a family reunion.

2609: Entwives

172.70.230.63: rv vandalism; please ban 👖🔥

{{comic
| number = 2609
| date = April 20, 2022
| title = Entwives
| image = entwives.png
| titletext = No, we actually do have a woman who's basically part of our fellowship. She lives in Rivendell, you wouldn't know her.
}}
*The comic is a link to a YouTube [https://www.youtube.com/watch?v=mt2qCjL6-n4 video].

==Explanation==
In {{w|The Lord of the Rings}}, the {{w|Ent|Ents}} are a species of tree-like humanoids, such as the one depicted in this comic. The comic shows an Ent, presumably {{w|Treebeard}}, meeting with some of the nine from the {{w|Fellowship_of_the_Ring_(characters)|Fellowship of the Ring}}. The image is inaccurate inasmuch as it shows three {{w|hobbits}}: during the Ents' interactions with the Fellowship, two of the four hobbits ({{w|Frodo Baggins|Frodo}} and {{w|Samwise Gamgee|Sam}}) were elsewhere in {{w|Middle Earth}}, so it was only {{w|Merry Brandybuck|Merry}} and {{w|Pippin Took|Pippin}} who met the ents. The other three in the image are the human {{w|Aragorn}}, the Dwarf {{w|Gimli (Middle-earth)|Gimli}} and the Elf {{w|Legolas}}. The last two of the nine, not depicted, were the wizard {{w|Gandalf}} and the human {{w|Boromir}}.

Part of the backstory of the Ents is that all the females of their species (the Entwives that this comic is named for) had disappeared thousands of years before during {{w|Sauron}}'s war of the {{w|History_of_Arda#Second_Age|second age}}. The Ents and the Entwives lived in separate locations, and eventually, when the Ents went to visit the Entwives, the latter were seemingly nowhere to be found. The Ents have been searching for their lost mates ever since. The loneliness of the Ents' all-male society is considered a great tragedy in their culture. It is several thousands years ago in the time of the Lord of the Rings trilogy, and the Ents have all but forgotten how the Entwives even looked. They live for many thousands of years.

This comic uses that backstory to satirically comment on the extreme gender imbalance of the protagonists of Lord of the Rings; when presented with the all-male Fellowship, the Ent assumes that they must come from a race afflicted by a similar tragedy. In a broader sense, this can be read as a commentary on how few female characters there are in the trilogy overall. In reality, the general lore presents, or at least mentions, the existence of at least multiple (if not numerous) female characters of almost all races that make up the fellowship (dwarf, man, elf, hobbit), and does not suggest that what happened with the Ents and their Entwives happened to any other race.

The clickable link on the image leads to the satirical video ''[https://www.youtube.com/watch?v=mt2qCjL6-n4 Lord of the Rings Trilogy but it's EVERY scene where two female characters interact]''. The creator claims that this shows all the scenes from the trilogy where two female characters interact (but later admits in the Youtube comments that there are indeed a few more). There is only one 3 second long scene, which only emphasizes how few female characters there are in the trilogy. The inclusion of this clip may be a reference to the {{w|Bechdel test}}, a baseline indicator of the representation of women in a piece of media that requires two women to have a conversation about something other than a man. Whether this three-and-a-half-word exchange is sufficient to pass the test is debatable. Later versions of the test suggest that the two women should be named (i.e. not just two incidental characters that have very few lines), whereas this scene is between {{w|Éowyn}} and an unnamed girl. There is debate as to if there are other scenes with women speaking with women, and if we are only talking about human women, or if other races females would also count. There are at least three important female characters, but they do not meet/speak much if at all. But they have several scenes where they talk, even a long monologue... But if they speak to someone it is male characters.

The title text most likely refers to the character of {{w|Arwen}}, an elf woman and, later, wife of Aragorn; while somewhat important to the story, she is nowhere near as significant as the males of the Fellowship, despite being used more prominently in the movies than in the books. Even if she were part of the Fellowship, a single important woman wouldn't counterbalance the heavily male-centric storytelling.

The way that the title text is phrased is a reference to the proverbial (and implicitly imaginary) "{{tvtropes|GirlfriendInCanada|Girlfriend in Canada}}," a trope in which a single American character claims to have a girlfriend that their friends wouldn't know "because she lives in Canada" (or some other sufficient separation such as "goes to another school"), when in reality the reason that nobody else has met her is because she doesn't exist. {{w|Canada}} is one of only two countries with which the United States has land borders, making it a potentially plausible place for some American's long-distance girlfriend to live, and presumably the Fellowship consider the Elf kingdom of {{w|Rivendell}} to be sufficiently distant to allow the Ent to accept the plausibility of the statement without any further delving into potentially awkward details.

==Transcript==
:[A large treelike person (an Ent, maybe Treebeard) is holding one of his arms out towards six characters that are all looking at him. A man (Aragorn) with beard stubble and long hair, a dwarf (Gimli) with a helmet and a very large beard, an elf (Legolas) with long blonde hair (holding a bow down), and three short persons, hobbits, two with dark hair, and the middle one with blonde hair.]
:Ent: Alas, there are no Ent women. The Entwives all vanished in the second age, during Sauron's war.
:Aragorn: I'm so sorry.
:Ent: And what about you all? Same story, I assume?
:Aragorn: Huh? No, what do you mean?

}}

==Explanation==
{{incomplete|Created by YÖDA'S COMPLETENESS THEOREM - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

'''This explanation is by mathematical necessity either incomplete or incorrect.'''

[[Cueball]] is falling into a common trap, because a little knowledge is a dangerous thing. Faced with some sort of information, of an unknown kind but seemingly not intrinsically mathematical in nature, he has decided that one possible way to proceed is to somehow translate everything into values which can be combined and compared numerically.

This is a very common thing to do, in fields as diverse as {{w|computational linguistics}} or {{w|sports analytics}}, and can be a powerful tool for understanding and learning new things about a subject as {{w|Data science}} tries to extract knowledge and insights from potentially noisy and disordered facts. But it is also used to implement bad science by using incorrect or misguided ideas about how to represent the source material. While it's possible to casually assign numeric values to random pieces of data, these numbers are generally not meaningful enough to compute with and draw any useful inferences from. It is generally possible to perform statistical analysis only on actual measurements, not on what may effectively be arbitrarily-assigned values.

Machine learning algorithms, which are commonly used by data scientists, typically require all their inputs to be numerical. However, most datasets contains categorical features (e.g. the description of a piece of furniture: chair, table, ...). Data scientists therefore use encoding techniques to convert these categorical features to a numerical form so they can be used as inputs to a machine learning model. For instance, label encoding consists of arbitrarily assigning an integer to a category (chair=0, table=1, ...) which may appear meaningless to most observers. In various cases, they may be right.

So, as well as being the mechanism that underlies one of the most profound theorems of 20th century mathematics, it can be mis-used for all kinds of bad or misguided science. From Cueball's attitude, it is far from clear that his attempt will reliably translate his project into a numerical system, nor that his attempt to "do math on it!" will be any more competent.

One of the major characters who looked at the concept is Kurt Gödel. He introduced the idea of {{w|Gödel numbering}} with his landmark {{w|incompleteness theorems}}. In it a unique natural number is assigned to each axiom, statement, and proof, which might otherwise be difficult to accurately process in any other kind of approach. Instead, it is now possible to create metamathematical statements in the language of mathematics.

This allowed Gödel to make the statement "This statement cannot be proven based on the axioms provided" in a mathematically rigorous way. A simple proof by contradiction shows that the statement cannot be false, and therefore (in most logical systems) must be true. The proof goes as follows: 1. Assume that "This statement cannot be proven from the axioms" (Call this statement G) is false.<ref>Call this assumption A.</ref> 2. Therefore G can be proven from the axioms.<ref>Because the negation of the negation is an affirmation. Based only on A.</ref> 3. The axioms exist.<ref>Call this assumption B</ref> 4. Therefore, G is true.<ref>via {{w|Modus ponens}} applied to 2 and 3, based on A and B</ref> 5. Therefore, G and also not G.<ref>via {{w|Conjunction introduction}} applied to 1 and 4, based on A and B</ref> 6. This is a contradiction, and therefore A (that is, 'not G') or B (ZFC) must be wrong. We are not willing to sacrifice assumption B, so we must conclude that A is false, given B.<ref>{{w|Reductio ad absurdum}} applied to 1,3, and 5</ref> 7. Therefore, G.

===Explanatory footnotes for the above===
<references />

Notice that the truth of Gödel's statement does not depend on any particular set of axioms, and adding axioms (such as "Gödel's particular statement is true") only opens up new iterations of the statement which cannot be proven based on the expanded set of axioms (A statement such as "All statements of a similar nature to Gödel's particular statement" is not precise enough to serve as an axiom.). As such, with a little more legwork, it can be proven that any logical system robust enough to accommodate arithmetic must necessarily contain facts that are true within the system but cannot be proven or disproven within the system. The importance of this result cannot be understated, as it upended the entire philosophy of mathematics. {{w|David Hilbert}}'s famous proclamation "We must know, we will know" is simply incorrect. ... Either that, or (ironically) Gödel used an "inconsistent" or "incomplete" system to produce his result.

The title text suggests that Gödel should perform such an analysis on different branches of mathematics, by calculating the average of all the fields' theorems' Gödel numbers. This is nonsensical for a number of reasons:
:1) Gödel is long dead, and dead people can't write articles;{{Dubious}} - see [[599: Apocalypse]]
:2) Gödel numbers grow very large very quickly, and depend heavily on the specific values assigned to each logical operator. Therefore the results could be manipulated simply by changing the numbering order of each operator;
:3) It may be very hard to gather all theorems in a field, or even a representative sample;
:4) Different fields of science, like biology or human behaviour, may not be able to write their theorems in the mathematical language of Gödel's incompleteness theorem
If anyone were to attempt this form of analysis, it would be an example of the bad data science described in the caption.

2611: Cutest-Sounding Scientific Effects

| titletext = The Stroop-YORP number of a scientific paper is how many of the 16 finalist names (sans 'effect') it manages to casually sneak into the text.
}}

==Explanation==
[[Randall]] has compiled [[:Category:Tournament bracket|yet another]] {{w|Tournament bracket|single-elimination tournament bracket}} for a knock-out competition, by public vote, between 16 different scientific effect names that he seems to consider worthy of being cute-sounding.

As of the release day, he is determining the result in a [https://twitter.com/xkcd/status/1518701311763570689 series of Twitter polls]. These results are shown [[#Result of the Twitter polls|here]].

See [[#Effects|below]] for explanations for what each of the 16 effects are.

Several unrelated scientific effects were previously combined in [[1531: The BDLPSWDKS Effect]], which also included the Stroop effect (the last S).

In the title text, Randall coins the term "Stroop-YORP number" as a count of how many 'casual' references a future publication can sneak into it from the 16 finalist names for cutest effect. It specifies that it should be without the word effect after the words (sans 'effect').

Tongue-in-cheek 'counting scores' are familiar in the likes of the {{w|Erdős_number|Erdős}} and {{w|Bacon_number|Bacon}} numbers, both of which are referenced by [[599: Apocalypse]] (the latter only in the title text). In these cases the ideal is to get the ''lowest'' number, whereas here higher is better. The cross-field hybrid {{w|Erdős–Bacon number}} is one in which the desired score is the lowest sum of both values (neither being undefinable) by dint of having participated in both arenas of respective achievement, but not necessarily (or practically) in a single combined presentation.

For instance the Stroop-YORP number could be high for a wildlife paper. That could possibly use "butterfly" and "rabbit" (possibly needing the latter to be specifically 'cutaneous', to count), which may both be found in "little parks" with some "popcorn" seen littered around without too much "oddity"; and of course a (Dr.?) "fox" could be in the area, getting a score of 6. But other words may be a stretch, with an imaginative reference to a "woozle" possibly easier to employ than to evoke anything of the "nocebo".

On the other hand, for a space-science paper there may be more obvious (mis)uses for physics-related terms, and mentioning YORP might well be expected. But it may need creative thinking to introduce the rabbit or the more psychological idea of Stroopicity, etc, without reason to discuss the responses of animal or human payloads being sent there.

It is not actually obvious whether Randall intends the score to only be valid if the insertions are off-field and/or undetected, such as when someone is wagered that they can slip unrelated song lyrics or a 'hello' to Jason Isaacs into a public speech without the rest of the audience twigging.

A search of google scholar indicates many articles with a score of 2 (e.g. [https://www.tandfonline.com/doi/full/10.1080/87559129.2012.714435 this paper], which refers to butterfly shaped popcorn), but 3 or more seems to not be attested.

==Effects==
;{{w|YORP effect}}: The YORP effect is the effect of sunlight on an asteroid with variations of shape and/or albedo, which can increase its rotation rate and/or modify its axis of rotation. It can cause objects to eventually spin apart or drastically change their orbit.
:It is an acronym of the names Yarkovsky, O’Keefe, Radzievskii and Paddack, who were instrumental in its discovery. More than a century ago, Yarkovsky determined that heat applied to a symmetrical rotating body would be asymmetrically re-emitted and apply a small but continuous thrust, and this was added to by considering the forces to non-symmetrical bodies.

2612: Lightsabers

2022-05-11T18:04:57Z

172.70.230.63: Undo revision 267017 by 👖🔥 (talk) (rv vandalism)

<noinclude>''For the comic named "Lightsaber", see [[1433: Lightsaber]].''</noinclude>
{{comic
| number = 2612
| date = April 27, 2022
| title = Lightsabers
| image = lightsabers.png
| titletext = A lot of Jedi romances start with this turning into a Lady and the Tramp spaghetti situation.}}
A {{w|lightsaber}} is a fictional beam-like sword weapon used by members of the {{w|Jedi}} order and the {{w|Sith}} in the ''{{w|Star Wars}}'' franchise. This comic shows a lightsaber fight starting between two [[Cueball]]-like Jedi, one already presenting their blade in challenge and the second activating theirs in response. When the first strike is made between the two lightsabers, they meld together with a bloop sound, like the beams are made of a liquid. The two light beams then remain stuck to each other. In in-universe "technical documents", lightsabers are said to be made from magnetically-confined plasma, so perhaps the magnetic fields which were projected from each hilt have merged instead of repelling (or presenting as mutually impervious) as is usually expected.

(This scene actually looks a lot like what happens between Harry Potter and Voldemort's wands in the end of the fourth book, the {{w|Harry Potter and the Goblet of Fire|''Goblet of Fire''}}. Here two spells hit each other and connect the two wands, the wand holders then unable to release or disconnect the wands.)

First the left Jedi, then the right, shakes the hilt, trying to break the bond. When this does not succeed, the right Jedi then deactivates his lightsaber in an attempt to end the connection. This causes the retraction of the entire double-sized light beam into the handles (as seen in the movies), causing both of the Jedi to be drawn together until their heads bonk, forcefully enough to render them both unconscious. The connected lightsaber handles lie next to them on the ground.

The title text implies that such events are how {{w|Jedi}} romances start, comparing it to the famous "spaghetti scene" from the 1955 Disney animated movie ''{{w|Lady and the Tramp}}'' where the two titular characters unintentionally kiss after sharing a strand of spaghetti. In the Old Republic, Jedi were forbidden from entering into romantic relationships (and discouraged from forming attachments in general), but in the pre-Disney ''Star Wars Legends'' continuity of the {{w|Star Wars in other media|Expanded Universe}}, {{w|Luke Skywalker}} and {{w|Mara Jade}} first met while fighting in the aftermath of the fall of the Empire, and then developed a romantic relationship.

Star Wars is a [[:Category:Star Wars|recurring theme]] on xkcd, and lightsabers have been prominently featured before in, for instance, [[1397: Luke]] and [[1433: Lightsaber]], where the problem with the physics of a light beam as a sword is shown. But in general light does not interact with light as {{w|photons}} are {{w|bosons}} and can thus pass through each other. Interference, yes, but two pure light beams cannot collide and bounce back as when two lightsabers collide. Also as the comic Lightsaber mentioned above shows, there is no compatible real-world way of confining a beam of light, making it stop after about a meter (or anywhere){{Dubious}} - see {{w|Optical cavity}}.

==Transcript==
:[Two Cueball like Jedi are engaging each other in a duel using lightsabers over 12 panels of equal size, with sound effects as the only sound. In the first panel the left Jedi has his lightsaber extended holding it in both hand pointing towards the other, who at this time is just turning his lightsaber on.]
:''Tssssss''
:Click

:[Almost same position of the Jedi, but the right Jedi's lightsaber has now extended, making a sound. He is holding it up near his head in both hands]
:''Tsss''

:[Then they run towards each other and swing their lightsabers towards each other, two small arcs indicating the swing of the lightsabers.]

:[The two beams hit each other and connects at the middle in a big bloop of light, with drops of "light" jumping off both above and below the connected lightsabers. Both Jedi still holds on to their handles with both hands. A loud sound comes out of the connection:]
:''Bloop''

:[The Jedi stands still holding their handles. The beam is now forming a bow between the two handles.]

:[The left Jedi violently shakes his handle causing a wave to travel down the beam towards the right Jedi.]
:Shake shake

:[The right Jedi shakes his handle and well and another wave travels the opposite direction towards the left Jedi.]
:Shake shake

:[Back to the bow of light between them, but the beam is visibly still shaking, but no wave is traveling any longer.]

:[Same setting but the shaking has stopped. The right Jedi turns his lightsaber off on his handle with a sound:]
:Click

:[The beam of light is retracted quickly into the handle of the Jedi turning his lightsaber off. So quickly that the two Jedi, still holding on to their handles are pulled up in the air and towards each other as the sound of the beam turning off is heard. Lines indicate their movement and shadows on the ground beneath them indicate they are in the air.]
:''Zhhhiiiip''

:[When the beam is completely retracted the two handles collide and so do the heads of the two Jedi with a loud sound. They still hold on to their handles with both hands. They still hang in the air with shadows on the ground beneath them.]
:''Bonk''

:[In the final panel the two Jedi lie unconscious on the ground with their heads towards each other and with their arms stretched out towards each other. The connected handles lie between them.]

1328: Update

2022-05-09T16:45:45Z

172.70.230.63:

{{comic
| number = 1328
| date = February 10, 2014
| title = Update
| image = update.png
| titletext = I have a bunch of things open right now.
}}

==Explanation==
When developers responsible for fixing errors on a specific {{w|Operating System|operating system}} release a patch, the operating system often ask users to restart the computer after installing. This is often done by popup window shown to the user where they can choose to restart immediately or choose to be reminded later.

Many messages from these popups emphasize the importance of installing the updates, but [[Cueball]] is just annoyed about this. Sometimes, these issues are minor and do not affect most computers using the operating system. Often other programs, not part of the operating system, ask for a reboot because the updated routine only runs after the next reboot. Regardless, reboots can take a long time — a typical user doesn't like this. The user can choose to be reminded later multiple times. Because {{w|Reboot (computing)|rebooting}} a computer takes a significant amount of time and closes any programs running, a user may delay the update repeatedly to avoid interrupting what they were doing at the time.

The comic is making two jokes simultaneously: the core comic jokes that reboots are so tedious and disruptive it would actually be preferable for a laptop to burst into flame than to go through one, while the title text suggests that the real problem is that humans are so incapable of delayed gratification and/or risk evaluation they would rather risk bodily harm than suffer a minor inconvenience.

The joke uses an "exploding laptop battery" as an exaggeration for comedic effect. Most software doesn't affect hardware issues like burning
[CITATION NEEDED] {{w|Lithium-ion battery#Safety|laptop batteries}}. However, low-level software, such as the {{w|kernel (computing)|kernel}} or {{w|driver (software)|drivers}}, might cause hardware to misbehave.

The title text reflects the fact that the average user will have multiple applications open and a reboot would require closing them. They would then have to open all their applications again after the computer has restarted. This can also refer to a browser application having multiple tabs open. This is becoming less of an issue because browsers have an option to restart the last session again after being closed, as would happen with a reboot, but many users still don't trust it to work properly.

==Transcript==
:[Cueball sits at a desk. A message is being displayed on Cueball's laptop screen.]
:'''Urgent''': Critical update available!

:[The message continues.]
:'''''Details''''': Fixes an issue that was causing random laptop electrical fires.

:(This update will require restarting your computer.)
:[Cueball clicks on ''Remind me later''.]

Hey all, the group theory thing reminds me a lot of cyclic groups or ideals generated by the value 2. Also equivalence classes (which come up in group theory) can be written with [brackets] but may be confused with <cyclic groups> or (ideals).

The 2;2 notation looks like the notation \mu; \nu that is used for covariant derivatives of tensors in physics. Also 2,2 looks like \mu, \nu that is used for partial derivatives of tensors. And as mentioned above, (2) could be a cyclic subgroup or ideal generated by two or a special case of cycle notation for elements of symmetry groups used to mean an element that keeps 2 fixed. [[Special:Contributions/162.158.62.120|162.158.62.120]] 23:32, 2 May 2022 (UTC)

I second the point about tensors. Maybe you could expand the summation notation slightly. It's common to use index sets or rules underneath large symbols for all sorts of things, like sums, products, direct sums, direct products, unions, intersections, integrals, and much, much more. So here, the large 2 in parentheses represents one of these symbols. Rather than adding or multiplying the elements or whatever, you are twoing them, whatever that means. You are twoing over all values of 2, apparently. It's sort of reminiscent of jokes with punchlines like "for sufficiently large values of 2." There are of course, different 2s out there. Like, there is the von Neumann ordinal 2, the integer 2, the rational number 2, the real number 2, the complex number 2, the residue class of 2 mod 3, etc. All of these may be represented by 2. Perhaps we are indexing over some collection of canonical representations of 2? [[Special:Contributions/172.70.130.161|172.70.130.161]] 00:02, 3 May 2022 (UTC)

The comment about combinatorics, in the section about the "cursed" stuff, uses superscript and subscript 2s. But that isn't quite correct; they should be stacked rather than one after the other. It *should* be possible to get the proper display using math mode, which is permitted in the main body of explanation though not in the transcript. I think it *ought* to be something like "<math>{2}\choose{2}</math>", but when I try it, I get an error: "Failed to parse (Missing <code>texvc</code> executable. Please see math/README to configure.)" -- clearly I don't know what I'm doing. Can someone who's more knowledgeable than I am fix that, please?

755: Interdisciplinary

{{comic

| date = June 18, 2010
| title = Interdisciplinary
| image = interdisciplinary.png
| titletext = Replace the pendulums with history students and you'll qualify for a grant!
}}

==Explanation==
An "interdisciplinary program" is a program at a school or university that involves students from multiple disciplines, or fields of study. Here, this comics lampoons the concept by envisioning an oddball exercise involving physics students and psychology students. Strictly speaking, this could be categorized as an interdisciplinary program. Further, the study of pendulums is common in physics courses, and the concept of fear arises in psychology, thus the joint effort can be supposedly said to unify both subjects.

The intersection of physics and psychology suggests the classic demonstration in which someone holds a heavy pendulum up against his face and releases it. Basic physics shows that the pendulum will, at most, harmlessly touch the person's face on the backswing (provided that he released it with no initial push and does not lean forward); however, it may take some force of will to refrain from flinching as the pendulum approaches. This experiment (with Black Hat's twisted take) is referenced in [[1670: Laws of Physics]] and [[2539: Flinch]].

In another example where the two concepts meet, the pendulum-like motion of objects (such as a gold pocketwatch on a chain) is stereotypically used in portals of psychology as a device for hypnotism.

The ripping of Psychology, History, and English majors is a common theme in various xkcd comics.

The image text suggests that replacing the pendulums with history students would guarantee funding of a grant, perhaps because of the increased number of disciplines involved. In reality it of course serves to increase injuries among students in majors that the author does not approve of. Interestingly, this is apparently being said by the grant funders rather than the professor.

1120: Blurring the Line

| date = October 12, 2012
| title = Blurring the Line
| image = blurring the line.png
| titletext = People into masturbatory navel-gazing have a lot to learn about masturbation.
}}

==Explanation==
A {{w|metaphor}} is a comparison which may be used to emphasize, explain or embellish a point, as seen in this comic when [[Cueball]] likens himself to Michael Jordan. {{w|Michael Jordan}} is a famous {{w|basketball}} player who is well known for being one of the very best basketball players (this saying was used before in [[1027: Pickup Artist]]).

[[White Hat]] is analyzing a movie about movies when Cueball compares White Hat's description of the movie to masturbatory {{w|Omphaloskepsis|navel-gazing}}, a comment combining two expressions used to refer to a pointless activity or effort, but also specifically self-referential activity. "Mental masturbation" and "navel gazing" are relatively common terms to dismiss work that is regarded as self-indulgent, overly introspective, and self-referential. Calling navel gazing, or introspection, "masturbatory" is a metaphor speaking of it in terms of the physical act of {{w|Masturbation|masturbation}}.

White Hat then defends the movie by saying that it is about blurring the line between metaphor and reality, commenting that Cueball doesn't understand art. To this Cueball retorts by likening his ability to meld metaphor and reality by using a metaphor comparing himself to Michael Jordan. He then proceeds to actually blur the line by throwing a basketball at White Hat. This can also be understood as another reality metaphor, passing the "conversational ball" to White Hat, or acting like Michael Jordan by playing basketball.

The last frame is also a graphic illustration of blurring the line between metaphor and reality, where a much more "real" depiction of a basketball intrudes into the colorless stick-figure world which serves as an abstraction of our shared reality.

The title text blurs the line between metaphor and reality by dragging both metaphors in the term "masturbatory navel-gazing" into reality and pointing out that literally staring at your navel is not going to be very effective at physical sexual self arousal, which is the goal of masturbation.

Another comic that blurs the line of a metaphor is [[1320: Walmart]].

1064: Front Door

<div style="display: none">crap</div>
{{comic
| number = 1064
| date = June 4, 2012
| title = Front Door
| image = front_door.png
| titletext = FYI: I'll be releasing a wolf into a randomly-chosen front yard sometime in the next 30 years. Now your fear is reasonable, and you don't need to feel embarrassed anymore. Problem solved!
}}

==Explanation==
This comic is showing in graphical form three different actions/feelings as [[Randall]] is approaching his front door at night. His "Fear That There's Something Behind Me" rises, so then his "Forward Speed" rises to get to his door faster. And then when he gets in the door and finds that in fact, there is nothing behind him, his "Embarrassment" rises. The y-axis of the chart is not labeled, so it is presumed to indicate amount, as in how embarrassed Randall is.

The interesting fact revealed is that Randall gets more concerned that someone is behind him when he walks up the steps to this door, and not while walking in the yard where there might be more hiding places. The worst fear is just before he walks up the steps to lock himself in. This is probably because now that he is almost home and safe, he now has to fumble with the key concentrating on getting the key in the lock, thus not being able to pay attention to what's coming up behind him.

This is of course an irrational thought, but it seems to happen to many people, and has certainly been used for suspense in many movies, whether it is "Did I hear a noise upstairs?" or "Is that an axe murderer hiding in that hedge?" or "There might be a [[:Category:Velociraptors|velociraptor]] lurking nearby". (However in all of these cases getting inside would probably not help you anyway just adding to the funny part of how the fear drops once inside. See [[87: Velociraptors]] for why getting inside probably also would not help against them.)

The title text attempts to alleviate the problem of the following embarrassment by introducing potential threat that could affect anybody. Since Randall mentioned that he will randomly release a wolf into a front yard sometime in the next thirty years, there will always be a fear that a wolf has been released onto your front yard. In that case, the fear one feels will be justified and not embarrassing, as it is possible that there is indeed a wolf released by Randall into their front yard. However, even assuming that Randall can find and release a wolf onto someone's front yard, the chance of this happening to you is minuscule.

==Transcript==
:[A graph with three colored lines. There is no scale on the Y-axis but the X-axis represents geographic location and has four labels. From the Y-axis to around the midpoint is "Yard", with an arrow from the word yard pointing left, at a point beyond the midpoint there is a tick labeled "Steps", at a point after that is another tick labeled "Door", and all points afterward are "Inside" with an arrow pointing right from the word inside, there are no tick for the first and last label. The three lines are all labeled with a small lines going from the label to the lines. The blue line begins to slowly increase from the start, with a slight dip further into the yard, and a steep increase right before the steps, maxing on the steps, and declining steeply at the door, bottoming out once inside. The gray line is at a steady medium height until it gets to the steps, at which point it shoots upwards, and then slowly declines once inside. The red line stays at 0 until just before the steps, where it begins to trend upwards, spikes at the door, and begins to slowly decline once inside. Above the curves to the left there is a black frame with the title of the graph:]

| date = May 2, 2022
| title = 2
| image = 2.png
| titletext = It's like sigma summation notation, except instead of summing the argument over all values of i, you 2 the argument over all values of 2.
}}

==Explanation==
{{incomplete|Created by 2 squared - Please change this comment when editing this page. The titletext needs to be worked in there, but I think I got everything else in some sort of order, pending general improvements. Do NOT delete this tag too soon.}}

This demonstrates the different ways in which the number 2 can be typeset in various scientific fields.

The dotted box represents any character (presumably a letter or bigram of letters). All the other notation consists only of the digit 2, in various fashions with occasional additional punctuation, and labelled as to what the 'purpose' might normally be of any particular element(s) as indicated, with respect to the general term, in the following fashions:
;Regular Math
:Precedes the term. "2x" indicates two times the value of ''x'' in normal {{w|algebra|algebraic}} use that should be familiar for many people.
;Physics
:A preceding superscript. "2H" would indicate the particular {{w|isotope}} of Hydrogen with the atomic weight of two, i.e. deuterium, which is most often encountered when working with the atomic level of matter where the total number of neutrons and protons in the atom is important.
;Chemical Physics
:A preceding subscript, "2He" indicates the atomic number of an atom, which is the number of protons it contains, and thus a guide to the number of electrons its unionised form usually has and hence meaningful in its potential chemical interactions with other atoms. This should be invariant for any particular named element, but is usually given simultaneously with the presuperscripted mass number where it can be indicative of the applicable nuclear physics.
;Regular Math or Footnotes
:A trailing superscript is typical of a {{w|Exponentiation|power value}}, in this case "x²" would be ''x'' multiplied by a second copy of itself, and a fairly typical mathematical standard.
:Additionally, superscripted numbers are one common way to mark words in a line of text in a way to refer to a {{w|Note (typography)|footnote}}, typically placed at the bottom of the page, with additional information that would not be appropriate or easily comprehendable to edit into the main text itself. The ambiguity between footnotes and exponents was used in [[1184: Circumference Formula]]
;Chemistry
:A trailing subscript is used in chemistry to indicate a multiple of the element (or group of elements, in brackets) in a {{w|chemical formula}}. "H2O" indicates two hydrogen atoms bond with a single oxygen atom in a molecule of water.
;Matrices!
:Extending the trailing subscript with a comma-separated value usually indicates a multidimensional array (e.g. establishing a 2-by-2 square of numbers, or this particular position in such an array), which is in the realms of {{w|Matrix (mathematics)|matrix mathematics}}. This is a little bit beyond 'everyday algebra' for many people, as seemingly indicated by the exclamation of the mere mention of matrices!
;The Physicists Are At It Again
:This label encompases a mark that turns the prior comma into a semicolon, as part of the trailing subscript. This is a common notation for the {{w|Covariant derivative}} of a tensor field, which is commonly used in the mathematics of general relativity.
;Either High School Math Function or Incomprehensible Group Theory
:The number 2 in parentheses that follow a term would normally be the argument to a {{w|Function (mathematics)|function}}, e.g. "f(2)", which means that you should take the value (in this case 2) and find the result if manipulated by the predefined function ''f''. It is generally taught as part of algebraic mathematics already described, i.e. at {{w|Secondary school|High School}}.
:In {{w|group theory}}, however, the number 2 in parentheses could indicate a cyclic subgroup or ideal generated by two or a special case of cycle notation for elements of symmetry groups used to mean an element that keeps 2 fixed. This may be somewhat beyond high-school level.
;Oh no. Whatever this is, it's cursed.
:A symbol centered underneath another symbol is normally reserved for doing summations, where the big symbol is Σ, or some other operation applied to a sequence of numbers.
:It does not make sense to have a single number there, as indicated in the alt text. As with [[2529: Unsolved Math Problems|other things]] in Randall's comic universe, the explanation for this particular anomaly is that it is 'Cursed'.

Was the lack of women in the fellowship because of "the cultural biases of the era in which the novels were written", i.e. a novel writing trope?

==Explanation==
{{incomplete|Created by an EVENS RATIO - Do NOT delete this tag too soon.}}
This comic is a misunderstanding of statistics very similar to that of [[1252: Increased Risk]]. It explains that going outside for more than 5 hours per day significantly increases your risk of head injury from falling spacecraft, and advises to limit outside activity to avoid this risk.

However, since the odds of being hit in the head by (any part of) a falling spacecraft are astronomically low to begin with [https://www.livescience.com/33511-falling-nasa-satellite-uars-risk.html], quadrupling it or more still results in a negligible probability. The horizontal error bars for times greater than 4 hours are marked with asterisks to indicate they are significantly different from the reference value at 0 hours, as indeed those error bars don't overlap the vertical line for the 0-hours reference value.

{{w|Error bar}}s are graphical representations of the variability of data and used on graphs to indicate the error or uncertainty in a reported measurement.

Presenting the data by hour brackets hides the data distribution inside each bracket. If the data were presented hour by hour, and not by groups of hours, they may show a different threshold of increased risk or no threshold (odds ratio could be linear).

The graph and error bars are based on a {{w|Monte Carlo Method|Monte Carlo simulation}}, a type of computational algorithm that uses repeated random sampling to obtain the likelihood of a range of results of occurring; see, for instance, this article about [https://www.ibm.com/cloud/learn/monte-carlo-simulation Monte Carlo simulations]. Additionally, this may indicate that the entire study was conducted via a Monte Carlo simulation and that no real data was collected adding to the absurdity of the claim that more time spent outside could lead to an increased risk of head injuries due to falling space craft. Indeed, it is so rare for humans to be struck by spacecraft debris that a simulation is probably the only way to study the risk; an absurdly large sample size, involving tens of millions of participants over several decades, would be necessary to obtain significant experimental data.

The specific reference to falling spacecraft is likely inspired by events happening around the time of this comics release (March 2022). Around a month before this was posted, the head of the Russian space agency, {{w|Roscosmos}}, warned that sanctions against Russia (mostly those over the {{w|2022 Russian invasion of Ukraine}}) could result in the {{w|International Space Station}} crashing. Since the Russian section of the space station is the one that provides propulsion (although it is built to rely on the power generated by the other sections), this was taken seriously and as of when this was posted, {{w|NASA}} was trying to come up with alternative stabilization strategies in case the situation worsened. There was also a recent [https://www-uol-com-br.translate.goog/tilt/noticias/redacao/2022/03/17/parte-do-foguete-spacex-e-encontrada-por-morador-do-pr.htm?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=pt-BR&_x_tr_pto=wapp report] of some 600 kg space rocket debris found in Brazil.

The title text makes a similar joke. While the increase in chances of death by a bear attack are greater when going outside than the decrease in chances of death by cardiovascular disease, by getting out to exercise, it is incorrect to combine them in this way, since cardiovascular disease has a much higher starting chance of death, and reducing it by 30% has a much more significant effect on overall life expectancy than quadrupling the very very small chance of death by bear attack.

The "280% increase" of the title text is also an error, though perhaps not for reasons that are obvious at first (for instance, the correct calculation is not "300% − 30% = 270%"). To "increase by 300%" means multiplying the probability by (1 + 3.0) = 4.0, while to "decrease by 30%" means multiplying by (1 − 0.3) = 0.7. Combining these means multiplying by both, for an overall change of 4.0 × 0.7 = 2.8, or 280%. However, this result means the risk has increased ''to'' 280% of its old value, not ''by'' 280%. And in any case, it is ''still'' not valid to simply combine two changes in wildly different risks like this.

===Odds & Odds Ratios===

The odds of an event is the probability that it happens divided by the probability that it doesn't happen. People often express odds as a ratio (e.g. the odds of rolling a 6 on a 6-sided dice might be expressed as 0.16777... : 0.83333..., or equivalently as 1:5), but it is important to note that such ratios are not ''odds ratios'' (it would be fitting to call this a "probability ratio", but this terminology is not standard).

An odds ratio is the odds of event O happening, given that some other event E has occurred, divided by the odds of O given that E has not occurred. O is sometimes called an "outcome" and E is sometimes called an "exposure", because people are often interested in comparing things like the odds of getting lung cancer (O) given that you smoke (E) to the odds of getting lung cancer given that you don't smoke, as a way of measuring the extent to which exposure to E influences outcome O. In the case of the comic, the outcome variable O is the event of getting a head injury from falling spacecraft debris, and the exposure variable E is the event of spending H hours per day outside, for various values of H. The comic appears to be saying that for each value of H, there are two options for E: either you spend H hours per day outside or you never go outside.

So for small values of H (e.g. 1 hour per day), the comic is saying that the event of being hit by spacecraft debris is more or less independent of the event of spending H hours per day outside, which is to say that the odds of being hit is more or less the same regardless of the choice you make between spending H hours per day outside and never going outside. Hence the dot on the 1-hour bar is close to 1, because the two odds are more or less equal (the dot appears to represent an average estimate of the odds ratio).

Note that when calculating the odds ratios for this comic, the odds in the denominators are always the same, as they are the odds of being hit given that you never go outside, which does not depend on H. So when the comic says that the odds ratio is above 3 for H={11+ hours per day}, it is effectively saying that the odds of being hit when you spend this much time outside is a bit more than 3 times the odds of being hit when you spend 1 hour per day outside.

Suppose the probability of being hit is: P when you spend 1 hour per day outside, and Q when you spend 11+ hours per day outside. The odds of being hit under these two exposures are P/(1-P) and Q/(1-Q) respectively, and because the odds ratios have equal denominators, the comic is saying that Q/(1-Q) = kP/(1-P), where k is a bit more than 3. If we rearrange this to get an expression for Q, we get:

<pre>
Q/(1-Q) = kP/(1-P)
<=> Q(1-P) = kP(1-Q)
<=> Q-QP = kP-kPQ
<=> Q+kPQ-QP = kP
<=> Q(1+kP-P) = kP
<=> Q = kP/(1+kP-P)
<=> Q = P/(P+(1-P)/k) {by dividing the numerator and denominator by k}
</pre>

As P is negligibly small, 1-P is very close to 1, and P+(1-P)/k is very close to 1/k. Thus Q is very close to kP (i.e. a bit more than 3 times P), meaning that the probability of being hit when you spend 11+ hours per day outside is still negligibly small. Thus, the comic's suggestion that we spend 4 hours or less outside based on the estimated odds ratios is extremely misguided.

:[A chart is shown. Above the chart there is a heading, with a subheading below it:]
:Odds ratio for head injuries from falling spacecraft debris
:(Monte Carlo Simulation)

:[The chart is rectangular with the X-axis labels above the chart with numbers from 1 to 5. These are places over vertical lines. The first at 1 is black, the other four are light gray. There are three smaller light gray ticks between each set of lines, and one on either side of the first and last. The distance between lines gets smaller and smaller towards the right, probably logarithmic.]
:X-axis: 1 2 3 4 5

:[The Y-axis is not scaled; there are no ticks or lines. Instead it just gives five labels from top to bottom. Above those labels there is an arrow pointing to the top one with a label above explaning the axis.]
:Hours spent outdoors per day
:Y-axis:
::0 (ref)
::1
::2-4
::5-10
::11+

:[Aligned with each of these five divisions of the Y-axis there is a dot. The top one is placed on the solid line under 1 as a reference point. The other four dots all have long error bars, with the dots at the center of these. The second dot is a bit to the left of the solid line, with the error bar going almost to the left edge of the graph and halfway to the first light gray line to the right. The third dot is located halfway between the solid and the first light gray line with the error bar just crossing the solid line, and almost reaching the gray line. The fourth dot is about a third way between the first and second of the gray lines, with the error bar crossing both these lines. The fifth and last dot is just past the second gray line, with the error bar crossing both that, going more than half toward the first gray line, and also just past the third gray line. On the same height as the two bottom dots, there are asterisks just right of the edge of the graph.]

:Our new study suggests that spending more than 5 hours outside significantly increases your risk of head injury from spacecraft debris, so try to limit outdoor activities to 4 hours or less.

==Trivia==
*In the [https://www.explainxkcd.com/wiki/images/archive/d/d5/20220329223238%21spacecraft_debris_odds_ratio.png original version] of the comic the Y-axis label referred to "hours spent outdoors". So more than four hours spent outdoors in one's lifetime would be a problem.
**But later the comic was edited to specify "hours spent outdoors per day", which makes more sense.
*When the new version was uploaded, Randall again made the error of making the two versions of the comic image the same size, as he did earlier in [[2576: Control Group]], see that comic's [[2576: Control Group#Trivia|trivia]]
**This resulted in the problem that the comic broke the boundaries on the xkcd website.
