==Explanation==
[http://conwaylife.com/wiki/Conway John Conway], an English mathematician, passed away of [[:Category:COVID-19|COVID-19]] on April 11, 2020. ({{w|John Horton Conway|alternative link}}) Two days later, [[Randall]] created this [[:Category:Tribute|memorial comic]]. It is the 6th memorial comic, but it is the first released in almost 5 years, since [[1560: Bubblegum]].

One of Conway's most famous creations was the {{w|cellular automaton}} known as {{w|Conway's Game of Life}}. A cellular automaton is a machine composed of cells, each of which can be in a different state. Every generation, each cell in the automaton may transition to a new state depending on a set of rules. (Conway's work in mathematics was vast and various, but he is perhaps best known in the field for discovering the {{w|surreal numbers}}, which inspired [[Donald Knuth]] to write a novel which may have been referenced back in [[505: A Bunch of Rocks]].)

Conway's Game of Life was first popularized to the general public in the form of a game, Life Genesis, bundled into some distributions of Windows 3.1, an operating system from the early-90s that Randall most likely used in his preteen years.

Conway's Game of Life is a 2-state automaton (i.e., every cell can be "alive" or "dead") that is implemented on a two-dimensional grid of cells using the {{w|Moore neighborhood}} - this means that each cell can only be influenced by the eight cells directly surrounding it, both orthogonally and diagonally. The transition rules that Conway used are as follows:

* If an "alive" cell has no live neighbors, or only one live neighbor, it becomes "dead". (This simulates death by isolation).
* If an "alive" cell has four or more live neighbors, it becomes "dead". (This simulates death by overcrowding).
* If a "dead" cell has exactly three live neighbors, it becomes "alive". (This simulates birth).

Despite the simplicity of these three rules, Conway showed that patterns of amazing complexity can nonetheless develop out of simple cell arrangements. Some patterns do not evolve at all ("still lifes"), some enter a cyclic, repeating state ("oscillators"), and some reproduce their own pattern displaced by an offset, resulting in patterns that can move across the grid under their own power ("gliders" and "spaceships"). This last category is of particular interest, as it allows the Game of Life to transmit information from one location to another, allowing for rich, dynamic behavior and even for the creation of computational machines within the automaton itself.

This comic begins with the shape of a stick figure as the starting cell configuration of the Game of Life. The black cells are "alive" and the white cells are "dead". This configuration then evolves via Conway's rules, disintegrating into nothingness except for a five-cell pattern known as a "glider", which ascends up and to the right. This visually suggests an eternal "soul" breaking away as the corporeal body disintegrates. The glider is perhaps the most iconic pattern of the Game of Life, and is often used symbolically to represent the phenomenon of emergence.

Here the topology of the grid on which the cells evolve is not known, the cellular automaton can be run on many topologies, for example you can choose to make cells reappear from the opposite side once they reach an edge (similarly to the behaviour of the well known Pacman). Here once the glider reaches the top right, we know for sure that the actual grid is bigger (since the glider leaves the frame while continuing its pattern), and we are only seeing part of the full grid.

The initial state presented in the comic does actually evolve in that manner, as can be verified by entering the pattern into a cellular automaton simulator such as [http://golly.sourceforge.net/ Golly] or web services such as [https://bitstorm.org/gameoflife/ this one] or [http://catagolue.hatsya.com/object/xkcd_48jsj8gzwe9e/b3s23 that one]. It seems that no one else have created this pattern before. At least, despite discussion in the comments, no one has found anything to show that this is not Randall's own discovery of this pattern.

The title text simply states Conway's birth and death year: 1937-2020.

Conway's Game of Life was previously mentioned in [[696: Strip Games]]. Cellular automata was also referenced in [[505: A Bunch of Rocks]].

This comic is the 18th comic in a row (not counting the [[2288: Collector's Edition|April Fools' comic]]) in a [[:Category:COVID-19|series of comics]] related to the {{w|COVID-19 pandemic}}. Although this comic is, of course, mainly a tribute to John Conway, the fact that he died of COVID-19 in the middle of this long series of coronavirus-related comics by Randall is relevant.

==Transcript==
:[A pixelated image of a stick figure using 21 pixels, could be a pixel Cueball, which waves with one hand up while holding the other hand down. The head consist of 7 pixels, the top row of three having two pixels beneath the two outer pixels, thus having two empty pixels beneath the central pixel. The neck and torso is a typical cross made from six pixels. The two legs are two pixels each shifted left and right of the cross. The arm to the left that waves is two pixels one down and the next back up to the level of the cross central beam. The arm to the right has the first pixel similarly but the second pixel continues one further step down. After less than one second it turns out that the image is animated, with the pixels changing according to the rules of Conway's Game of Life. The figure splits into three groups, two of which dissipates in a similar way at the bottom of the panel. The other becomes a 'glider' and moves off to the top-right corner of the image and out of the frame. The animation then repeats.]

Why is 'Barack Obama is 6'1"' and 'Barack Obama has 4 legs' medium precision? It seems to give exact value, so high precision. [[User:Tkopec|Tkopec]] ([[User talk:Tkopec|talk]]) 11:44, 9 November 2022 (UTC)
: OK, I get it. 6'1" means something between 6'0.50" and 6'1.49". For height it's OK, but when counting legs, it seems like a stretch. [[User:Tkopec|Tkopec]] ([[User talk:Tkopec|talk]]) 12:30, 9 November 2022 (UTC)
:: The four legs are probably considered to be only medium precise, not because of the number but because of the imprecise term "leg". While humans can walk on all four extremities, thereby using them as legs, the upper two are commonly referred to as arms. [[User:Bischoff|Bischoff]] ([[User talk:Bischoff|talk]]) 14:54, 9 November 2022 (UTC)
:: (ECed by Bischoff) Plus a person's height (excluding differences to footwear and perhaps hairstyle) varies by an inch or so over the course of a day, as the spine compresses whilst mostly upright (would depend a bit upon your daily activities, but "an inch" or 2-3cm is the typical quoted value, with all the questions about precision ''as well as'' accuracy). Within an inch of such a foot-and-inch value is basically between slightly over a percentage point of drift across a continuum of ultimately non-integer values.
:: The number of legs is ''generally'' a whole number (perhaps lower-limb amputees could claim "half a leg", but is that for above the knee or below or... that's beyond my wish to define, I would leave it up to the individual amputee to finesse to their own liking) and assigning decimals, even .000(recurring), would be ''over-''precise. A definite plain figure (however inaccurate) being the happy and acceptable medium between that and the vague imprecision (never mind inaccuracy) of the kind in the cell below.

::That there is confusion over this was a bit of a surprise to me, about 20 years ago, when I worked (as I did for many years) in the outdoor pursuits trade. GPS units would give a 12-character grid reference (1m2), but couldn't be relied upon to that level. I would tell people they're more precise than they are accurate, until it became apparent that they were waiting for me to complete the joke they thought I'd begun, as I was so clearly contradicting myself, what with the two words meaning identical things.

:::(In fact, the other day I was geohashing myself, and my device was insisting I was in a totally different bit of the open field, 50m or so, no matter how much I sat it down at the provably correct point and wandered away so that even ''I'' wasn't obscuring its view of the sky.

High Precision High accuracy, Randall Munroe misses when Obama was president. Low precision Medium-rare accuracy, so do we, Randall, so do we. {{unsigned ip|172.70.130.154 }}

It is so annoying that the US uses . and , to mean the opposite of what most European countries (including Denmark where I live). So when I read this it states that Obama was president less than 3 days (70 hours) but it more than 70000 feet tall. :-) Of course I now the difference but I have to think about it more than if everyone used the same standard. Also height should use SI units as everyone should ;-) (weight given in number of cats is the new SI unit as far as I know, but don't use inches and feet ;-D ) --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 08:17, 10 November 2022 (UTC)

I think Randall missed an opportunity to clarify how high precision can make something inaccurate. He could have said that Obama is 6’ 1.02173” tall, which would clearly be very precise, and also clearly inaccurate, simply because of the excessive precision. [[User:John|John]] ([[User talk:John|talk]]) 15:22, 10 November 2022 (UTC)
:Saying 6'1.0278 would have been more in theme, there. And it would be not really more inaccurate (might even be closer to the truth...) but would convey a false precision.
:Interstingly, when Andrew Waugh measured Mount Everest (before it was so named) he got a diffraction-adjusted figure of 29,000 feet, but decided to announced that it was 29,002 so that it didn't just like a rough figure rounded to the nearest hundred or even thousand feet. This made him the first person to put two feet on the top of Everest!
:(...The actual error was not bad, given his measurements had to be made from hundreds of miles away. Current official measurements with on-the-spot modern GPS say 29,031.7 feet (for the snow-peak, which is all that Waugh could mention), after 170ish years of (by some estimates, but contested) about a foot of extra height per decade through the continuing techtonic raising of the Himalaya. And any unknown differences in snow-depth. Certainly it was within tens of feet, i.e. a dozen or so metres. With a bit of an error-bar, but not really that big when you consider it...)
: So, arguably, that case was a deliberately false accuracy to help convey the true precision. [[Special:Contributions/172.70.90.3|172.70.90.3]] 16:15, 10 November 2022 (UTC)

::The only thing I can imagine is, that these kinds of numbers happen due to conversions. E.g. 6ft1in would be 185.42cm (according to the first calculator I found), but it is unlikely that 6ft1in was as precise as a cm-value with 2 digits after the decimal point would be. And in the other direction 185cm (which would be the usual precision of a height in m or cm - while 186cm could still be correct as it would be 6ft1in in the "usual precision") would calculate as 6ft and 0.83in --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 10:18, 11 November 2022 (UTC)
::If Obama's height is provided with this much precision, you can assume that the numbers are made up. 0.0278 inches are - in real measure units ;-) - 0.07mm. That's the diameter of a strain of hair. Nobody's height gets measured to that kind of precision. [[User:Kimmerin|Kimmerin]] ([[User talk:Kimmerin|talk]]) 08:10, 17 November 2022 (UTC)

I'm not sure the current explanation's claim that 'being too precise usually decreases accuracy' is, er, accurate (or perhaps it's just imprecise). It might be reasonable to claim that increasing precision tends to decrease accuracy relative to the level of precision, but not so much in absolute terms, or even necessarily relative to the size of the thing being measured.[[Special:Contributions/141.101.107.156|141.101.107.156]] 09:38, 11 November 2022 (UTC)
:I think it's badly phrased. The assumed accuracy can be degraded and disadvantageous.
:For example, to use someone's figures from just above, looking for an individual with a height of 185.42cm might seem to rule out the one that you find is 185.57cm tall, though they are indeed the one initially measured/estimated at 6'1" and would definitely be within an inch or so in this latest attempt to match them.
:An old phrase that I grew up with is "don't try to be accurate over inaccurate details" (courtesy of a chemistry teacher, where we frequently used mmol-like measurements in analyses like titrations). The number of articles that say "the probe flew past the asteroid at a distance of about 20 miles (32.187 kilometres) ...", where clearly the accuracy is misleading, especially if the conversion ends up being back-converted by someone else with no idea ("...which is 20.0000746 miles"), and may have come from an ''original'' figure actually deliberately pegged at 35km (21.748 miles!), within a few metres or less.
:Really, you should be taking the level of precision/accuracy inherent in the initial values, preserving the awkward fractions throughout the intermediate steps ''and'' converting the inherent ranges by the same process then clearly presenting the final figure to no more exactitude than the initial smudge of "all actual values that would be given by this type of input value", and maybe less. The write-up might be then be realistically "...of around 21¾ miles (35km)", if using a better primary source, or "20 miles (~30km)" in a case of the detail already being likely lost by intermediate chinese-whispers.

::It gets even better when different units also use different 0s. So for a persons height we can assume that as 0ft0in and 0cm is the same, 185cm is one order of magnitude more precise than 6ft1in, as it is 3 significant digits vs 2 at the same height. However a persons body temperature in 38°C with 2 significant digits and 311K with 3 is the same level of precision and only .15°C (Or .15K) apart, while 100°F (37.77...°C) is also very close but a bit more precise. --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 14:10, 11 November 2022 (UTC)

One of the defining features of OCD is the compulsion to keep track of things, ''e.g.'' which hand touched something, how many steps someone has taken...

Not sure about any of the others but, while cricket may not be easy for players to 'strip' to (more for padding/helmet/box reasons, and maybe the complexities of working out how it works in a team game), streaking in cricket is a thing. (Perhaps it helps that it's typically a warm, dry weather sport, hot sun, ''plenty'' of time to drink alcohol in the stands, and then ''if'' you find the opportunity to wander near the pitch with the idea of a less-than-fully-clad 'invasion' and there's nobody currently there to stop you, well...) Was going to add something like [https://www.cricketcountry.com/articles/20-instances-of-streaker-invasions-in-cricket-part-i-517971 this link to the article, but it's terribly written (and patronisingly so) and in an ad-avalanched page that I don't care to casually encourage anyone to visit. It's there if you want it, but I couldn't put this caveat in the main explanation. Instead I linked to the wikipage of a random example individual I found (who seems not to regret her initial streaking 'fame') as a representative of the genre.

1264: Slideshow

2024-02-11T23:11:17Z

Squishmallow fan: you need the descriptions you need the descriptions you need the descriptions

{{comic
| number = 1264
| date = September 13, 2013
| title = Slideshow
| image = slideshow.gif
| titletext = Points to anyone who hacks the Flickr devs' computers to make their text editors do this when you click on anything.
}}

==Explanation==
It is very common for websites to feature a gallery of images – a website for a school, for example, might feature pictures of the students and teachers. Some websites display images in the form of a slideshow like this comic, with slow zoom and pan effects and fades between the images. This effect has been dubbed the {{w|Ken Burns effect}} after documentary filmmaker {{w|Ken Burns}} who popularized the effect. In many cases, the slideshow is a fixed element, and can't be controlled by the user. This prevents the user from navigating through the images at their own pace or viewing any one image for an extended period, and can be distracting. [[Randall]] expresses frustration at this.

The title text suggests points will be awarded to whoever can add that annoying effect to the text editors of the developers of {{w|Flickr}}, a photo-hosting website, so they can be subjected to the same thing to which they are subjecting Randall. This may be a response to recent changes to Flickr's website that includes such slideshows as one option; that said, Flickr has always allowed users to browse galleries in a normal grid layout and with user-controlled photo-by-photo full-window layout.

This one is the most get-out-of-my-mind I have ever experienced with xkcd. And I had quite a few of these :-)
I recently had this very same thought, and eventually I managed to find a way to get audiobooks and podcasts just mixed up in the very same app and very same environment. And it's been an absolute joy switching around between them. Drastically increased my book-reading.
I have been telling everyone who wants to hear about it. 
Anyone curious to do the same I greatly recommend using PodcastAddict and its integrated "virtual podcasts" feature.
That one allows you to create a "podcast" from a selected folder with audiofiles. 
Combine this with Audiobookstore.com or any other place where you can actually download books you purchase, and you can have the same set-up.

It is so annoying that the US uses . and , to mean the opposite of what most European countries (including Denmark where I live).

I think Randall missed an opportunity to clarify how high precision can make something inaccurate. He could have said that Obama is 6’ 1.02173” tall, which would clearly be very precise, and also clearly inaccurate, simply because of the excessive precision. [[User:John|John]] ([[User talk:John|talk]]) 15:22, 10 November 2022 (UTC)
:Saying 6'1.0278 would have been more in theme, there. And it would be not really more inaccurate (might even be closer to the truth...) but would convey a false precision.
:Interstingly, when Andrew Waugh measured Mount Everest (before it was so named) he got a diffraction-adjusted figure of 29,000 feet, but decided to announced that it was 29,002 so that it didn't just like a rough figure rounded to the nearest hundred or even thousand feet. This made him the first person to put two feet on the top of Everest!
:(...The actual error was not bad, given his measurements had to be made from hundreds of miles away. Current official measurements with on-the-spot modern GPS say 29,031.7 feet (for the snow-peak, which is all that Waugh could mention), after 170ish years of (by some estimates, but contested) about a foot of extra height per decade through the continuing techtonic raising of the Himalaya. And any unknown differences in snow-depth. Certainly it was within tens of feet, i.e. a dozen or so metres. With a bit of an error-bar, but not really that big when you consider it...)
: So, arguably, that case was a deliberately false accuracy to help convey the true precision. [[Special:Contributions/172.70.90.3|172.70.90.3]] 16:15, 10 November 2022 (UTC)

::The only thing I can imagine is, that these kinds of numbers happen due to conversions.

I'm not sure the current explanation's claim that 'being too precise usually decreases accuracy' is, er, accurate (or perhaps it's just imprecise). It might be reasonable to claim that increasing precision tends to decrease accuracy relative to the level of precision, but not so much in absolute terms, or even necessarily relative to the size of the thing being measured.[[Special:Contributions/141.101.107.156|141.101.107.156]] 09:38, 11 November 2022 (UTC)
:I think it's badly phrased. The assumed accuracy can be degraded and disadvantageous.
:For example, to use someone's figures from just above, looking for an individual with a height of 185.42cm might seem to rule out the one that you find is 185.57cm tall, though they are indeed the one initially measured/estimated at 6'1" and would definitely be within an inch or so in this latest attempt to match them.
:An old phrase that I grew up with is "don't try to be accurate over inaccurate details" (courtesy of a chemistry teacher, where we frequently used mmol-like measurements in analyses like titrations). The number of articles that say "the probe flew past the asteroid at a distance of about 20 miles (32.187 kilometres) ...", where clearly the accuracy is misleading, especially if the conversion ends up being back-converted by someone else with no idea ("...which is 20.0000746 miles"), and may have come from an ''original'' figure actually deliberately pegged at 35km (21.748 miles!), within a few metres or less.
:Really, you should be taking the level of precision/accuracy inherent in the initial values, preserving the awkward fractions throughout the intermediate steps ''and'' converting the inherent ranges by the same process then clearly presenting the final figure to no more exactitude than the initial smudge of "all actual values that would be given by this type of input value", and maybe less. The write-up might be then be realistically "...of around 21¾ miles (35km)", if using a better primary source, or "20 miles (~30km)" in a case of the detail already being likely lost by intermediate chinese-whispers.

::It gets even better when different units also use different 0s.

The chief advantage of the American system is that placing the year last makes it easy to simply drop the year in casual conversation, given how slowly years change. While it might technically follow just as logically to have the day precede the month, in practice the sequence means less for the first two numbers. The 31 days or fewer between month changes are relatively frequent, while the 365.25 days between year changes can easily go "out of sight, out of mind" except when approaching a transition. In either case, placing the nigh-irrelevant year number first in the text string causes the reader to pay attention to that number first, and have to "skip ahead" to discover the month and day, when in truth the day is the most salient datapoint.

::::[[User:Frankie|Frankie]], funny how the nonaveraged plots [and even the averaged plot] [[#wikimedia|linked]] to below invalidates Randall's plot, "Hence the comparison is not comparing like with like and is scientifically invalid." The temperature rate between 1859 (coincident with America's discovery of petroleum and the Carrington Event) and today does not exceed that within the past 2,000, 20,000, or 100,000s of years. The present surge (the tip of the "hockey stick") concerns not 100 years but almost 40 years (36 years in Randall's plot) which does not successfully meet the three fluctuation disclaimers. As mentioned in the Wikimedia discussion the temperature resolution is about 300 years; therefore it should take another 150 years to see whether this slope corrects itself.

Okay, now that I've managed to SEE the damn thing, I have a question. There's no mention of why this is using "BCE" and "CE" instead of the standard "BC" and "AD", never mind what these stand for (thinking and thinking about it, my guess is "Before Christ Era" and "Christ Era"). This is the kind of thing that should be mentioned on ExplainXKCD, LOL! Fun fact: when I searched this page for "BCE", to confirm it wasn't explained, I got "Over 100 matches". :) Anyway, I figure maybe those are currently accepted scientific terminology, especially since "AD" is Latin, unlike "BC", but the average person still uses BC and AD. In fact, I think this is the first time I've ever seen BCE and CE (unless it's been on XKCD before and I just dismissed it as a typo or something.

What this comic doesn't show is what kind of changes occurred in the previous interglacial period as opposed to the current one. Since the current one is not yet over there could still be a stage of an interglacial with rapid temperature rise which we are only now reaching, but has happened in previous interglacial periods.

I think this would be first time where I see global thermonuclear war described as "best case scenario". There was and still is lot of discussion about how much is current warming caused by humans, but that's not important. Important question is "can we stop it?" and the answer is "not without literally billions of dead" (and even that might not suffice). Any money currently used for most plans to reduce CO2 (which usually fails to reduce CO2, not speaking about global warming, but succeed in their main goal, which is moving the money into pockets of their proponents) would be better spent on ADAPTING to the change. Only plans for reducing CO2 actually worth doing are the ones related to stopping burning fossil fuels, because we will soon need fossil fuels to make food (and other stuff) from. Oh, and also stop burning FOOD. So we should replace fossil fuel power plants with only viable alternative - NUCLEAR. So called renewable power sources like solar are good addition, but doesn't scale to the amount of power and stability we need. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 14:12, 15 September 2016 (UTC)

Also, for the person who suggested we look at previous interglacial periods, I may be wrong, but I believe a lot of that data comes from ice cores, that would make it hard to look at time periods before the present ice sheets existed.

The jump of 0.5 degrees from 2000 to 2016 has been shown to be false. It exists because "scientists" went back and changed (or "seasonally adjusted") their data to fit their preconceived conclusions.

::Yeah, the long sample intervals and best fit curves from pre-industrial temperature estimates tend to smooth out any rapid changes that may have occurred over the time period (Think of an ECG/EKG that took a single instantaneuos microvolt sample once every 15 minutes of your life from birth to death, the resulting deflection graph would not look like anything like a normal heart rhythm, but it could be interpreted as the average electrical activity of your heart over the course of a lifetime). It's true that the rapid climate shifts we are able see in geological records usually coincide with things like supervolcano eruptions and asteroid impacts. But those shifts are usually to the negative end from the nuclear winter effect. Idea for reversing global warming without affecting CO2 emissions, just send a couple of hypervelocity rods or a gravity-tractored asteroid into a dormant supervolcano caldera every few years and... instant winter.

Very interesting and important work.

Actually.... Solomon and Jesus are not historical figures. Outside the Old and the New Testament, there is no archaeological or other evidence for their existence. I suppose, Jesus has played a significant role in history. So, you may be justified to add an entry saying something like "Date that religious traditions hold as the date of birth of Jesus."

Then, if you mention, say, Shakespeare, then you should also mention the estimated composition of the Bible, an event with more important historical influences.

Roman empire was continued for more than thousand years (Eastern Roman Empire, today reffered as Byzantium).

Current scholarly wisdom is that the Homeric epics, (the Iliad and the Odussey) were composed at the second half of the 8th century, perhaps around 720 BCE.

== "Sad comics" ==
<blockquote>...So after the election of a climate change denier later in the year of this comic's release, several sad comics have been posted. Some of the reason could be that Randall no longer believes that even his worst fears (as expressed by the current path at the bottom) will hold up, when USA gets a president, who will on purpose act in a way that scientist claims will make the temperature rise even more. See more here.</blockquote>

I've mentioned this on the talk page for [[2137: Text Entry]], but I'll reiterate it here: this observation is not factual, not relevant to the explanation, and does not belong in the description of this comic. If you read it in context, you will see that it is also a non-sequitur, clumsily inserted after one or two factual sentences - it does not follow from anything prior in the discussion. It is poorly expressed and the point being made is unclear in any case.

While the user doing this may well have honest intentions, they are simply defacing articles with their own anti-Trump projections and spamming a link to their own, misleadingly-titled page ([[Sad comics]]) which has no clear meaning or explanatory value.

The industrial revolution and its consequences have been a disaster for the human race, and this graph shows it.[[Special:Contributions/172.68.50.19|172.68.50.19]]
:I agree that it has probably been a disaster (certainly a gamechanger) for the ecosystems, causing changes and challenges that are so much different to what everything else woupd have experienced without such a heavy hand of humans upon the planet. But for "the human race",vI wonder if there'd be so many billions of us if industrial (and post-malthusian) developments had never arisen. By a simplistic numbers game, we are (currently) ranking higher than it seems likely a more nature-tuned alternative 20th/21st-Century would have looked like.
:A higher population doesn't guarantee "success", I know, and only hindsight will say for sure whether unprecedented growth leads to unprecedented decline in the same 'scoring' value (indicating that it isn't the best score to use long-term), but some would say this. (Not me, I'm just philosophising here.)
:Beyond this, if only by entering the Industrial Age do we have the ability to foresee and forestall some asteroid impact..? Perhaps then the (somewhat damaged) ecosystem actually lives on 'better' (subjectively) from our flawed attempt to industrially improve the planet, to our own ends, the rediscovery of ecoprinciples and then the successful aversion of another planet-killing asteroid (or at least the development of "arks" to let the current biodiversity to ride out the problem, here or elsewhere). Unless you have the view that the post-now changes (like the post-dinosaur/etc changes) are themselves higher scoring on the nature-scale. (But then if an unaverted asteroid is equal to a prior one, then is our polluion of the world equal to when earlier organisms started to fill the atmosphere with deadly oxygen and convert the world to an entirely different phase of life?)
:What can definitely be said is that we're doing ''something'', but expect some people (who aren't actually full-on deniers) to suggest that it isn't really a bad thing. Which it probably is, of course. Or at least not the ''best'' thing, and there's probably better outcomes than the one we're tumbling into, by whatever measure.

::::[[User:Frankie|Frankie]], funny how the nonaveraged plots [and even the averaged plot] [[#wikimedia|linked]] to below invalidates Randall's plot, "Hence the comparison is not comparing like with like and is scientifically invalid." The temperature rate between 1859 (coincident with America's discovery of petroleum and the Carrington Event) and today does not exceed that within the past 2,000, 20,000, or 100,000s of years. The present surge (the tip of the "hockey stick") concerns not 100 years but almost 40 years (36 years in Randall's plot) which does not successfully meet the three fluctuation disclaimers. As mentioned in the Wikimedia discussion the temperature resolution is about 300 years; therefore it should take another 150 years to see whether this slope corrects itself.

Okay, now that I've managed to SEE the damn thing, I have a question. There's no mention of why this is using "BCE" and "CE" instead of the standard "BC" and "AD", never mind what these stand for (thinking and thinking about it, my guess is "Before Christ Era" and "Christ Era"). This is the kind of thing that should be mentioned on ExplainXKCD, LOL! Fun fact: when I searched this page for "BCE", to confirm it wasn't explained, I got "Over 100 matches". :) Anyway, I figure maybe those are currently accepted scientific terminology, especially since "AD" is Latin, unlike "BC", but the average person still uses BC and AD. In fact, I think this is the first time I've ever seen BCE and CE (unless it's been on XKCD before and I just dismissed it as a typo or something.

What this comic doesn't show is what kind of changes occurred in the previous interglacial period as opposed to the current one. Since the current one is not yet over there could still be a stage of an interglacial with rapid temperature rise which we are only now reaching, but has happened in previous interglacial periods.

I think this would be first time where I see global thermonuclear war described as "best case scenario". There was and still is lot of discussion about how much is current warming caused by humans, but that's not important. Important question is "can we stop it?" and the answer is "not without literally billions of dead" (and even that might not suffice). Any money currently used for most plans to reduce CO2 (which usually fails to reduce CO2, not speaking about global warming, but succeed in their main goal, which is moving the money into pockets of their proponents) would be better spent on ADAPTING to the change. Only plans for reducing CO2 actually worth doing are the ones related to stopping burning fossil fuels, because we will soon need fossil fuels to make food (and other stuff) from. Oh, and also stop burning FOOD. So we should replace fossil fuel power plants with only viable alternative - NUCLEAR. So called renewable power sources like solar are good addition, but doesn't scale to the amount of power and stability we need. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 14:12, 15 September 2016 (UTC)

Also, for the person who suggested we look at previous interglacial periods, I may be wrong, but I believe a lot of that data comes from ice cores, that would make it hard to look at time periods before the present ice sheets existed.

The jump of 0.5 degrees from 2000 to 2016 has been shown to be false. It exists because "scientists" went back and changed (or "seasonally adjusted") their data to fit their preconceived conclusions.

As you can see an atmosphere when healthy should have
Oxygen 25 - 32%
Carbon dioxide 0.1 - 0.15%
Average Temperature 14 - 18 °C
Sea level 60 - 180 meters
and there should be no polar ice caps

our sea level is at extinction levels
our carbon dioxide is almost too low for plants to survive
and our oxygen level is almost suffocatingly low

Less Carbon Dioxide means less Plants
Less plants means less Oxygen
Less Oxygen means less Life[[Special:Contributions/108.162.246.112|108.162.246.112]] 07:24, 17 September 2016 (UTC)

:I think the point of comics is that while there were changes in temperature before, they were never this rapid. Although I wouldn't be sure about THAT either ... granted, the previous rapid changes were accompanied with mass extinction ... -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 15:16, 17 September 2016 (UTC)
::Yeah, the long sample intervals and best fit curves from pre-industrial temperature estimates tend to smooth out any rapid changes that may have occurred over the time period (Think of an ECG/EKG that took a single instantaneuos microvolt sample once every 15 minutes of your life from birth to death, the resulting deflection graph would not look like anything like a normal heart rhythm, but it could be interpreted as the average electrical activity of your heart over the course of a lifetime). It's true that the rapid climate shifts we are able see in geological records usually coincide with things like supervolcano eruptions and asteroid impacts. But those shifts are usually to the negative end from the nuclear winter effect. Idea for reversing global warming without affecting CO2 emissions, just send a couple of hypervelocity rods or a gravity-tractored asteroid into a dormant supervolcano caldera every few years and... instant winter.

Very interesting and important work.

Actually.... Solomon and Jesus are not historical figures. Outside the Old and the New Testament, there is no archaeological or other evidence for their existence. I suppose, Jesus has played a significant role in history. So, you may be justified to add an entry saying something like "Date that religious traditions hold as the date of birth of Jesus."

Then, if you mention, say, Shakespeare, then you should also mention the estimated composition of the Bible, an event with more important historical influences.

Roman empire was continued for more than thousand years (Eastern Roman Empire, today reffered as Byzantium).

Current scholarly wisdom is that the Homeric epics, (the Iliad and the Odussey) were composed at the second half of the 8th century, perhaps around 720 BCE.

: First, the Guardian is a newspaper, not a science journal. Second, that article is from 2013, before the latest upsurge. Third, even ignoring those things, the article doesn't say what you claim it does. The single most optimistic sentence I see is ''"If we are lucky, the impact of burning all that oil, coal and gas could turn out to be at the less severe end of the plausible spectrum."'' The rest of the article is quite pessimistic, such as ''"it is overwhelmingly likely that we would shoot well past 2C and towards 3C or even 4C of warming."''

::: please explain how the Guardian graph you posted on imgur has to do with better scenarios. The title: "Cuts required for 50% chance of not exceeding 2°C". The footer: "CO2 emissions since 1850 (red); exponential growth (blue); cuts to hit climate target (dashed)." It says that in order to '''possibly''' reach the "optimistic" +2° scenario (Randall's 2nd line, not the 1st one), we would need to cut anthropogenic CO2 to about 1/10th our current level, which is ridiculously unlikely to happen. The other graphs you posted are just hypothetical extrapolations about energy production that, even if they're trustworthy (which I doubt) don't reference any climate scenarios at all, much less ones better than the timeline.

<blockquote>...So after the election of a climate change denier later in the year of this comic's release, several sad comics have been posted.

I've mentioned this on the talk page for [[2137: Text Entry]], but I'll reiterate it here: this observation is not factual, not relevant to the explanation, and does not belong in the description of this comic. If you read it in context, you will see that it is also a non-sequitur, clumsily inserted after one or two factual sentences - it does not follow from anything prior in the discussion. It is poorly expressed and the point being made is unclear in any case.

While the user doing this may well have honest intentions, they are simply defacing articles with their own anti-Trump projections and spamming a link to their own, misleadingly-titled page ([[Sad comics]]) which has no clear meaning or explanatory value.

The industrial revolution and its consequences have been a disaster for the human race, and this graph shows it.[[Special:Contributions/172.68.50.19|172.68.50.19]]
:I agree that it has probably been a disaster (certainly a gamechanger) for the ecosystems, causing changes and challenges that are so much different to what everything else woupd have experienced without such a heavy hand of humans upon the planet. But for "the human race",vI wonder if there'd be so many billions of us if industrial (and post-malthusian) developments had never arisen. By a simplistic numbers game, we are (currently) ranking higher than it seems likely a more nature-tuned alternative 20th/21st-Century would have looked like.
:A higher population doesn't guarantee "success", I know, and only hindsight will say for sure whether unprecedented growth leads to unprecedented decline in the same 'scoring' value (indicating that it isn't the best score to use long-term), but some would say this. (Not me, I'm just philosophising here.)
:Beyond this, if only by entering the Industrial Age do we have the ability to foresee and forestall some asteroid impact..? Perhaps then the (somewhat damaged) ecosystem actually lives on 'better' (subjectively) from our flawed attempt to industrially improve the planet, to our own ends, the rediscovery of ecoprinciples and then the successful aversion of another planet-killing asteroid (or at least the development of "arks" to let the current biodiversity to ride out the problem, here or elsewhere). Unless you have the view that the post-now changes (like the post-dinosaur/etc changes) are themselves higher scoring on the nature-scale. (But then if an unaverted asteroid is equal to a prior one, then is our polluion of the world equal to when earlier organisms started to fill the atmosphere with deadly oxygen and convert the world to an entirely different phase of life?)
:What can definitely be said is that we're doing ''something'', but expect some people (who aren't actually full-on deniers) to suggest that it isn't really a bad thing. Which it probably is, of course. Or at least not the ''best'' thing, and there's probably better outcomes than the one we're tumbling into, by whatever measure.

As someone has just Transcripted basically almost all the fine detail I had planned to entable in the Explanation, I shall not now create repetition. Though I had a little more description to the NORXONDOR GOGONAX, in particular, to reference bidirectional (antiparallel) diode pairings (e.g. an LED assembly that glows a different hue depending upon the applied current bias) as probable inspiration, and that latched Flip-Flops surely inspired some part of the Frankensteinian gate-types, too.

The symbol for norx gate (1-input OR, two outputs) I'd read as a noninverting buffer to increase another gate's usable fan-out. Xand gort resembles the symbol for an [[wikipedia:Operational amplifier|op-amp]]. Given the subtraction that an op-amp does, the xand gort's truth table probably resembles that of the [[wikipedia:Material conditional|"implies" operator]].

Right, "NORG XORT" would be a XNAND with inverted inputs, though I don't know what the logic table from a XAND or XNAND gate would look like.

258: Conspiracy Theories

2024-02-09T20:28:00Z

Squishmallow fan: /* Transcript */ you cant forget the ripple lines! :D

{{comic
| number = 258
| date = May 7, 2007
| title = Conspiracy Theories
| image = conspiracy theories.png
| titletext = There are a lot of graduate-educated young-earth creationists.
}}
==Explanation==
===Conspiracy theories===
A {{rw|conspiracy_theory|conspiracy theory}} purports to explain a social, political, or economic event as being caused or covered up by a covert group or organization. A typical example is the {{rw|Moon_landing_hoax|Moon landing conspiracy}}, which asserts that no human has ever reached the Moon.

Once a conspiracy theory starts, it often grows stronger. This is due to a "{{rw|Morton's_fork|Morton's fork}}", a situation where no matter what is observed, the same conclusion is reached:
*Facts agreeing with the theory are, of course, evidence for the theory.
*Facts disagreeing with the theory are considered part of the cover-up. This suggests that there is, in fact, a cover-up in the first place. Therefore, contradictions to the theory are also treated as evidence for the theory.

In the case of the Moon landing, conspiracy theorists assume videos of men walking on the Moon to be faked by Hollywood studios. The existence of the assumed fake videos "proves" the cover-up. Also, the absence of filming crew or anything else needed for faking a video is considered further proof of how carefully the cover-up was planned.

No matter what happens next, it will be taken as evidence for the conspiracy theory. As one person put it: "To a conspiracy theorist, there are only two kinds of evidence: evidence that proves their theory correct, and evidence that proves the conspiracy ''goes deeper than they ever imagined''." In reality, the more elaborate the cover-up, the less realistic it is. There would be many more details to expose, and many more people involved, each of whom could spill the secrets with a lower chance of being identified.

People promoting these theories belong to a small minority, but they gain attention from many people — often without much knowledge on that specific matter. People who have actual knowledge about a given subject just get frustrated by this, because it seems like smart or educated people should reject conspiracy theories for lack of proof. If a conspiracy theory does have proof, it is really science or investigative journalism.

The title text refers to {{w|Young Earth creationism}}, which claims that the Earth is only thousands of years old, instead of the billions of years evolutionary scientists suggest. Believers in this theory generally either ignore evidence for the Earth's age, claim it to be inaccurate or misinterpreted, or claim that it is all part of how the Earth was created. The "conspiracy theory" connection arises when they claim that scientists, for some reason, collectively refuse to consider (what they consider to be) evidence of a young Earth.

===Conversation===
In the comic, [[Hairy]] starts pointing out perceived "errors" in the {{rw|9/11|"official" 9/11 story}}, obviously starting to describe the {{w|9/11 conspiracy theory}}. [[Cueball]] immediately cuts him off, and delivers a speech about conspiracy theories being a {{w|glitch}} in reasoning that anyone can experience.

The overall message of the comic, which the title text elaborates upon, is to challenge the assumption that conspiracy theorists are stupid. On the whole, Cueball considers Hairy smart, and is heartbroken to see his friend waste his potential on this. He believes that Hairy, and other conspiracy theorists, have reasoned themselves into their position to some extent, but the reassurance from their belief now stops them from realizing that their initial reasoning was faulty. The comic asserts that ''anyone'' can fall into this pattern of thinking, no matter how reasonable or educated they are. The title text gives a point of evidence for this, that many Young Earth creationists are college-educated, and therefore cannot be written off as stupid in general.

Cueball acknowledges that he has been unable to get through to conspiracy theorists in the past, so he tries to get Hairy to see the light by talking about these experiences. He raises the {{rw|Logical_fallacy|logical fallacies}} involved in conspiracy theories in general, and compares Hairy's behavior to other conspiracy theories that he believes Hairy wouldn't have fallen for: {{rw|Young_Earth_creationism|Young Earth creationism}}, {{w|Moon landing conspiracy|the Moon landing}}, and {{rw|perpetual_motion|Perpetual motion}} machines. This is an effort to open Hairy up to the idea that he has, in fact, fallen for a conspiracy theory. When Cueball acknowledges his past debate partners as smart people who were misled by fictions anyway, he is trying to give some counter-reassurance so that Hairy isn't too embarrassed to admit he was wrong.

However, Hairy suddenly claims that humans never landed on the Moon, revealing that he does believe a theory that Cueball assumed was beneath him. Thus, we don't find out whether Cueball's approach would have worked otherwise. The two are left at an impasse where each thinks their beliefs should be obvious to the other; it is as if they are living in different realities. Cueball is so frustrated that he just walks away with no further comment.

In the last panel, Cueball asks {{rw|God}} to fix the error that allows otherwise reasonable beings to believe conspiracy theories. This follows from Cueball calling this behavior a glitch. This is a not-so-subtle joke as religious belief tends to be connected to certain conspiracy theories (such as Young Earth Creationism, as mentioned in the strip). The joke, then, is that Cueball believes in (and converses with) God, but instead of following religious conspiracy theories, uses the relationship for {{w|debugging}}.

A {{w|bug report}} is a description of some error, or "{{w|Bug (engineering)|bug}}", that occurred when using a computer program, to inform the developer of a problem that needs to be fixed. The comic draws a comparison between prayer and developer feedback. Filing a "bug report" to God should be unnecessary, as God is generally understood by believers to be omniscient. Thus, God must already be aware of the problem, and allow it to exist for explicable reasons of "God's will."

==Transcript==
:Hairy: The official story of 9-11 is full of holes. Take the—
:Cueball: Please, stop, because seeing this happen to you breaks my heart.

:Cueball: Conspiracy theories represent a known glitch in human reasoning. The theories are of course occasionally true, but their truth is completely uncorrelated with the believer's certainty. For some reason, sometimes when people think they've uncovered a lie, they raise confirmation bias to an art form. They cut context away from facts and arguments and assemble them into reassuring litanies. And over and over I've argued helplessly with smart people consumed by theories they were sure were irrefutable, theories that in the end proved complete fictions.
:Cueball: Young-Earth Creationists, the Moon Landing people, the Perpetual Motion subculture — can't you see you're falling into the same pattern?

:Hairy: You don't seriously believe we landed on the moon, do you?

:[Cueball walks away, frustrated, with ripple lines behind him.]

:[Cueball kneels down with folded hands, praying:]
:Cueball: Dear God.
:[Booming from the sky:]
:God: '''YES, MY CHILD?'''
:Cueball: I would like to file a bug report.

427: Bad Timing

2024-02-09T14:54:13Z

Squishmallow fan: added lakes

{{comic
| number = 427
| date = May 23, 2008
| title = Bad Timing
| image = bad_timing.png
| titletext = Protip: Even without the red spiders, never have that conversation halfway through a balloon ride.
}}

==Explanation==
[[Cueball]] breaks up with [[Megan]] in the middle of a {{w|hot air balloon}} ride. Then {{w|Non sequitur (literary device)|the red spiders attack}}.

The red spiders are among the earliest xkcd [[characters]], first appearing in [[8: Red spiders]].

As the protip in the title text states, a break-up conversation while you are stranded in an inaccessible location is very poor manners. Also, the suggestion may be interpreted that breaking up in a hot air balloon is a very dangerous way to do it; the reaction may result in one or both parties falling out of the basket, or at least make the remainder of the flight very awkward.

This was the first comic to give a ''protip'' in the title text, but several have followed, as can be seen in the [[:Category:Protip|protip category]].

The full series of [[:Category:Red Spiders|Red Spiders]] comics:
*[[8: Red Spiders]], the first one.
*[[43: Red Spiders 2]], in which the spiders begin building.
*[[47: Counter-Red Spiders]], in which the humans begin a counter-offensive.
*[[126: Red Spiders Cometh]], in which the spiders attack a city.
*[[427: Bad Timing]], this one.
*[[442: xkcd Loves the Discovery Channel]], in which it appears briefly in the 14th panel crawling over a cube.

==Transcript==
:[Cueball and Megan, flying in a hot air balloon that takes up most of the panel.]
:Cueball: I like you. I'm just not feeling the relationship.

:[The hot air balloon is now further away, and a rough sketch of the ground below with lakes is shown.]
:Cueball: I'm sorry.

:[Only the basket of the hot air balloon is shown, with the rest being cut off by the edge of the panel.]
:Cueball: It's just bad timing. Me with my classes, you with your work, the spiders...
:Megan: The what?

:[Red Spiders crowd onto the balloon, causing it to begin to fall. Cueball and Megan look panicked.]

Regrettably for someone who has mild dyslexia, and with it in All Caps, I have difficulty seeing the subtleties of the spellings. [[User:RIIW - Ponder it|RIIW - Ponder it]] ([[User talk:RIIW - Ponder it|talk]]) 09:08, 23 December 2023 (UTC)

I have defiantly left this typo as-is, on purpose, before.
[[User:ProphetZarquon|ProphetZarquon]] ([[User talk:ProphetZarquon|talk]]) 13:40, 23 December 2023 (UTC)

I buffed up the Explanation (basically replaced it, the editor-suggestions for 'other not-wrong-honest spellings' didn't fit. Maybe I should transplant that down here as a game for us all to play 'aside' from any Explain). Some phrasing or language I can see being ripe for going under the scalpel/wrecking-ball of the next editor to arrive here, but I think it's a decent framework that covers most of the points. Just the one thing I nearly added, but left off, was actually going into the various Word-Meaning pairs. I can imagine why some of the Meanings are used (seem to have a sense that aligns with the letter-jumble that makes the Word wrong), but not enough to do a full table about it (as an obvious attempt at over-analysis). But if anyone else has a yen to do so then... Just remember that I thought of it first. ;) [[Special:Contributions/141.101.99.59|141.101.99.59]] 16:14, 23 December 2023 (UTC)
: You beat me to it. I was unable to ascertain any way to link clues in the misspellings to the meanings assigned to them, and I think that the meanings were haphazardly, even absurdly, assigned. [[Special:Contributions/162.158.186.248|162.158.186.248]] 16:28, 23 December 2023 (UTC)
Not sure whether or not this merits a table, but I think the apparent reference to the 2008 film "Definitely, Maybe" is worth mentioning, at least. (I probably put it in an awkward spot, though.)[[Special:Contributions/172.70.174.134|172.70.174.134]] 17:55, 23 December 2023 (UTC)

47: Counter-Red Spiders

2024-02-09T02:13:55Z

Squishmallow fan: /* Transcript */ eleven. there is eleven

{{comic
| number = 47
| date = January 9, 2006
| title = Counter-Red Spiders
| before = <big><big>[https://web.archive.org/web/20060529063441/http://xkcd-drawings.livejournal.com/#:~:text=Drawing%3A%20Counter%2DRed%20Spiders LiveJournal title]: '''Drawing: Counter-Red Spiders'''</big></big>

}}

==Explanation==
This was the forty-forth comic originally posted to [[LiveJournal]]. The previous one was [[46: Secrets]], and the next one was [[48: Found]]. It was among the [[:Category:Posted on LiveJournal after xkcd.com|last eleven comics]] posted both on LiveJournal and on [https://xkcd.com xkcd.com] after the new site was launched. This comic was published on the same day across both sites, but not all of them shared the same posting day.

In previous comics, red spiders are seen navigating similar landscapes. Here, humanoid stick figures are standing on top of each other to reach some place above the top of the comic, in a similar manner to how the red spiders navigate, in order to engage in a {{w|counter-offensive}} against the red spiders. These stick figures must be extremely light, or gravity must be really weak there, because it is extremely unlikely or even impossible to have a stack of humans that tall.

The title text indicates that [[Randall Munroe|Randall]] hopes the counter-offensive is able to prevent the red spiders' attack. However, the invasion in [[126: Red Spiders Cometh|Red Spiders Cometh]] suggests that it may have been unsuccessful. In the original caption, he provides two links to the images of the previous comics. The links are now defunct, so here's the caption with the archived versions of the links: "[https://web.archive.org/web/20060529063826/http://www.xkcd.com/red_spiders_small.jpg They] must be [https://web.archive.org/web/20060529063826/http://www.xkcd.com/red_spiders_2.jpg stopped]."

The full series of [[:Category:Red Spiders|Red Spiders]] comics:
*[[8: Red Spiders]], the first one.
*[[43: Red Spiders 2]], in which the spiders begin building.
*[[47: Counter-Red Spiders]], this one.
*[[126: Red Spiders Cometh]], in which the spiders attack a city.
*[[427: Bad Timing]], in which, in a style more typical to xkcd, the spiders attack a couple in the middle of a serious relationship discussion in a hot-air balloon.
*[[442: xkcd Loves the Discovery Channel]], in which it appears briefly in the 14th panel crawling over a cube.

333: Getting Out of Hand

2024-02-09T01:47:34Z

Squishmallow fan: /* Transcript */ "a couple" is too vague.

{{comic
| number = 333
| date = October 24, 2007
| title = Getting Out of Hand
| image = getting out of hand.png
| titletext = Wikipedia's role as brain-extension, while a little troubling, is also really cool.
}}

==Explanation==
Given how {{w|Wikipedia}} has an ever-expanding variety of topics, the grand majority of them in great detail, there is a possibility (even a temptation) of relying on Wikipedia to learn from every topic that leaves you confused... even {{w|foreplay}}. ('Bedtime' and 'us time' are not necessarily 'computer time'.)

This comic may also be a reference to how people can get addicted to reading Wikipedia pages, because there are many interesting links on each page that people haven't read yet, and there are links on that page that they click on, etc.

The title text refers to the fact that many rely on Wikipedia instead of remembering/learning stuff. Reliance on Wikipedia was later directly addressed as the subject of [[903: Extended Mind]].

1679: Substitutions 3

2024-02-09T01:45:48Z

Squishmallow fan: updated because of the new year

{{comic
| number = 1679
| date = May 11, 2016
| title = Substitutions 3
| image = substitutions_3.png
| titletext = BREAKING: Channing Tatum and his friends explore haunted city
}}

==Explanation==
This is the third comic in the [[:Category:Substitution series|Substitution series]] where [[Randall]] has suggested substitutions that will make reading the news more fun. This time it will be even '''more''' fun! But there have been several [[:Category:Substitutions|comics using substitutions]] both before and after these ones.

The series as of 2023:
*[[1288: Substitutions]]
*[[1625: Substitutions 2]]
*[[1679: Substitutions 3]]

The title text in original form would be "Scientists explore ancient city", which most would consider a fairly bland headline. Two days before this comic came out, there was [http://www.independent.co.uk/news/world/americas/forgotten-mayan-city-discovered-in-central-america-by-15-year-old-a7021291.html news] that a potential ancient Mayan city had been found by a 15 year old boy through satellite imagery, which may be what Randall was referencing. The Mayan city has now been proven nonexistent. Imagining Channing Tatum and his "friends", and pretending that the city is haunted, provides a much more dramatic setting mirroring many episodes (and later films) of ''Scooby Doo'' featuring a gang of friends (Mysteries, Inc.).

1625: Substitutions 2

2024-02-09T01:38:53Z

Squishmallow fan: "suddenly" and "successfully" also are both adverbs

{{comic
| number = 1625
| date = January 4, 2016
| title = Substitutions 2
| image = substitutions_2.png
| titletext = Within a few minutes, our roads will be full of uncontrollably-swerving cars and our skies full of Amazon delivery dogs.
}}

==Explanation==
This is the second comic in the [[:Category:Substitution series|Substitution series]] where [[Randall]] has suggested substitutions that will make reading the news more fun. But there have been several [[:Category:Substitutions|comics using substitutions]] both before and after these ones.

The series as of 2016:
*[[1288: Substitutions]]
*[[1625: Substitutions 2]]
*[[1679: Substitutions 3]]

In this table, [[Randall]] suggests substituting several common phrases in generic news with similar or related phrases that mean something different for comical effect. Some of the replacements are {{w|synonyms}}, some are {{w|antonyms}}, and some are plain different concepts; and, even though they would (most of the time) make a grammatically correct sentence, the resulting idea would, however, often sound absurd or bizarre.

Some of the examples might, also, mock the fact that many news contradict the actual facts or obvious results of a situation. For example, "[influential person] vows to do good to the world" would be replaced with a more usual fact "[influential person] probably won't do good to the world" - see [[#Example of sentences|example]] below with North Korean leader.

The title text is an example of how the closing sentence of a given article or report might sound after using the substitutions in the comic.
:Before substitutions: Within a few '''years''', our roads will be full of '''self-driving''' cars and our skies full of Amazon delivery '''drones'''.
:After substitutions: Within a few '''minutes''', our roads will be full of '''uncontrollably-swerving''' cars and our skies full of Amazon delivery '''dogs'''.
The flying dogs could be a reference to [[1614: Kites]]. Was the first of two in a row where Amazon is mentioned in the title text (next [[1626: Judgment Day]]).

===Table of substitutions===
*In this table the difference between the original and the substituted word (and the change to the sentences) will be explained.
**[[#Example of sentences|Example of sentences]] are given below.

| {{w|Debate}}
| [https://en.wiktionary.org/wiki/dance-off Dance-off]
| A 'debate' is often used between political candidates, to give the voters a chance to decide who they will vote for. One of the candidates  is often called the winner of such a debate by some degree or other of consensus. Randall is indicating that they could just as well have performed a 'dance-off' where they would dance until one of them danced better than the other, as adjudged by the viewing crowd or a panel of judges. Such a dance-off is often seen in [http://gameshows.wikia.com/wiki/Family_Dance_Off TV-shows] or [http://www.imdb.com/title/tt3024964/combined films] etc.

Self-driving cars were still in their adolescence when this comic was written, and Randall pokes fun with the mental image of self-driving cars running completely out of control and swerving dangerously out of their lanes. Self-driving cars is a [[:Category:Self-driving cars|recurring topic]] on xkcd.

| {{w|Poll}}
| {{w|Psychic reading}}
| A 'poll', especially regarding political issues, refers to {{w|opinion poll|opinion}} or {{w|exit poll|exit}} polls. These tend to ask a carefully selected sample (for either balance or an intended ''inbalance'', depending on the poll's neutrality) their opinions in order to extrapolate the global consensus, e.g. the future result of an {{w|election}}. This substitution is Randall's way of saying that they could just as well have used a {{w|psychic}} person to predict the result. A true psychic (if that they are) would reveal an accurate result, whilst a false one (skilled at 'cold reading' an audience) would likely wish to provide the answer that pleases those asking the question (the actual purpose of some polls), or else attempt to provide their actual 'best guess' as to future outcomes in order to improve their own legend.
|-
| {{w|Candidate}}
| {{w|Airbender}}
| A 'candidate' usually refers to a political person who represents a certain political party in an election. He would then be that party's candidate, for instance for a presidential election. 'Airbender' refers to the show {{w|Avatar: The Last Airbender}}, where there are waterbenders, earthbenders, firebenders and airbenders.
|-
| {{w|Unmanned aerial vehicle|Drone}}
| {{w|Dog}}
| Drones can be many things, for instance a {{w|Drone (bee)|male bee}}, but as used in the title text it refers to unmanned aerial vehicles. {{w|Amazon.com|Amazon}} is about to use small drones to deliver parcels, and Randall has referred to these before (see [[1523: Microdrones]]). However, until just before the recent trend of becoming popularised as a 'toy' or professional camera platform, the term became closely associated with ''military'' drones that have been used to observe (and, more recently, fire upon) enemy forces without risking any military personnel.
|-
| {{w|Vows}} to
| [https://en.wiktionary.org/wiki/probably Probably] won't
| Vowing to do something means that you really promise to do this. But when politicians vow something, for instance, it seems to often end up becoming a forgotten promise. Hence the antonym substitution which means the opposite. From ''really will'' to ''probably won't''.
|-
| {{w|Fugitive#Terminology|At large}} (or {{w|At-large}})
| Very [https://en.wiktionary.org/wiki/large large]
| A criminal that is on the run is said to be at large (no hyphen). At-large (with hyphen) is a political designation for members of a governing body who are elected or appointed to represent the whole membership of the body, rather than a subset of that membership. Neither of these have anything to do with the physical size or "largeness" of the subject.
|-
| [https://en.wiktionary.org/wiki/successfully Successfully]
| [https://en.wiktionary.org/wiki/suddenly Suddenly]
| The two words have nothing much to do with each other except that they both begin with ''su'' and they are both adverbs.
|-
| [https://en.wiktionary.org/wiki/expand Expands]
| [https://en.wiktionary.org/wiki/physical Physically] expands
| 'Expands' often refers to a physical expansion, or inflation. But it is also possible to expand on an explanation, as is done for this comic. So that would become: This explanation is being physically expanded beyond all measures. It is worth noting that, if iterated, this substitution would result in an infinite string of of "physically"s prior to any "expand."
|-
| {{w|First degree|First }} /{{w|second degree|second }} /{{w|third degree|third-degree}}
| [http://da.urbandictionary.com/define.php?term=Friggin Friggin'] awful
| First, second and third-degree can be used in many context. It is common to think about {{w|Burn|burns}}, which can {{w|Burn#Signs_and_symptoms|range from first to fourth degree}}, where higher is worse. Also {{w|murder}} charges can range in from first to third degree in for instance the US. Here first degree murder is the worst. But it can be used for other things, like an {{w|undergraduate degree}} or {{w|postgraduate education}} for first and second degree respectively. But the substitution fits best with murder or burn, as Friggin(g) is a "softer" swear word than for instance other more commonly used four letter words. It often replaces ''fuck''. Its original meaning was a coarse word for female masturbation (see [https://en.wiktionary.org/wiki/frigging#English frigging]).
|-
| An [https://en.wiktionary.org/wiki/unknown unknown] number
| Like {{w|100 (number)|hundreds}}
| In the news, an unknown number mostly means 'probably not zero.' It is often used in phrases like "an unknown number of assailants broke into a house in Munroe Heights," or "an unknown number of people are missing" after a calamity of some sort. "Like hundreds" does give a different flavor.
|-
| {{w|Front-runner |Front runner}}
| {{w|Blade Runner}}
| In American politics, a 'front-runner' is a leader in an electoral race. It can also mean the front-runner in athletic events (the namesake of the political concept). Here it is generally clear who the front-runner is, whilst the political front-runner is sometimes less clear or a more subjective viewpoint. A 'blade runner' is a person who retires (kills) rogue cyborgs in the movie Blade Runner, where {{w|Harrison Ford}} plays the lead Blade Runner.
|-
| {{w|Globe|Global}}
| {{w|Spherical}}
| Global comes from globe, but means so much more today. It is often used in contexts such as {{w|global warming}} or {{w|World war|global warfare}}. But since a globe is spherical, this substitution makes more sense than most, although talking about ''the effect of spherical warming'' would probably not get {{w|Greenpeace}} into action. Might be confusing if an actual physical object affecting Earth were described as being sphere-like, rather than as occuring around the globe.
|-
| {{w|Years}}
| {{w|Minute|Minutes}}
| It will often make a sentence lose its meaning when changing the units drastically from years to minutes (there are 525600 minutes in the usual 365 days present in a year). For instance it would be unusual that a prisoner convicted for murder would get 20 minutes in jail, rather than 20 years.
|-
| {{w|Minute|Minutes}}
| {{w|Years}}
| Same as above but reversed. For instance a car might make a trip around a race track in just 7 years! One lesson at school lasted 45 years.
|-
| No {{w|Indication| indication}}
| Lots of {{w|Sign (disambiguation)|signs}}
| Scientifically, the fact that there is 'no indication' that a theorem is correct does not positively prove the theorem wrong, it merely does not support it (assuming there are no actual counter-indications, which is often the case with the more esoteric ideas). This is often seized upon by those trying to promote a pseudoscience, in that their chosen idea "has not been proven to be wrong" (and yet, conversely, "it's just a theory" is incorrectly used to refute something that has valid scientific backing). Moreover, hearsay and bad experimental practices are often cited as 'proof'. A crackpot idea may thus be unsupported by valid science (there is 'no indication' of its truth) and yet its supporters insist upon there being 'lots of signs' that it is true, selectively using only ambiguous results that (to them, at least) lend credence to it being a fact. The substitution of 'no indication' with 'lots of signs' thus automatically converts the expected conservative and cautious stance on some disputed issue or other into the weasel-words phrasing that the issue's supporters may start using in their own propaganda.
|-
| [https://en.wiktionary.org/wiki/urge Urged]{{w|Self-control|restraint}} by
| {{w|Alcohol intoxication|Drunkenly}} [https://en.wiktionary.org/wiki/egg_on egged on]
| If someone urges someone else to restrain themselves, then they are trying to make them exercise self-control, and discourage them from starting or continuing a possibly foolish act. In this substitution we have the exact opposite, as to egg someone on to do something is actively encourage an act to happen, or continue.
|-
| {{w|Horsepower}}
| {{w|Ton|Tons}} of {{w|horsemeat}}
| Cars power is measured in horsepower (hp), a typical family car having like hundred hp, being derived from the nominal amount of power that a suitably-harnessed horse could have provided. In cars, this has nothing to do with horse meat, of any quantity, but here a mechanical (or electrical) engine is envisaged as a literally horse-powered device.

Talk:2497: Logic Gates

2024-02-08T23:55:24Z

Squishmallow fan:

As someone has just Transcripted basically almost all the fine detail I had planned to entable in the Explanation, I shall not now create repetition. Though I had a little more description to the NORXONDOR GOGONAX, in particular, to reference bidirectional (antiparallel) diode pairings (e.g. an LED assembly that glows a different hue depending upon the applied current bias) as probable inspiration, and that latched Flip-Flops surely inspired some part of the Frankensteinian gate-types, too. [[Special:Contributions/141.101.99.119|141.101.99.119]] 00:08, 3 August 2021 (UTC)

(Also, surprised there was no direct "GONDOR" reference. Or maybe that's because it was ''too'' obvious?) [[Special:Contributions/141.101.99.211|141.101.99.211]] 00:12, 3 August 2021 (UTC)

: I was also missing a "GONDOR" reference, and all the X's also made me think XEHANORT. [[Special:Contributions/172.70.126.174|172.70.126.174]] 03:49, 3 August 2021 (UTC)

: Never mind GONDOR, surely "The black GATES of MORDOR" should feature heavily? 11:45, 6 August 2021 (UTC)

...So, who's ready to draw up some truth tables? [[Special:Contributions/172.70.126.211|172.70.126.211]] 01:22, 3 August 2021 (UTC)

The symbol for norx gate (1-input OR, two outputs) I'd read as a noninverting buffer to increase another gate's usable fan-out. Xand gort resembles the symbol for an [[wikipedia:Operational amplifier|op-amp]]. Given the subtraction that an op-amp does, the xand gort's truth table probably resembles that of the [[wikipedia:Material conditional|"implies" operator]]. [[User:Tepples|Tepples]] ([[User talk:Tepples|talk]]) 04:23, 3 August 2021 (UTC)

the "NORG XORT" is not equivalent to an XOR, as the symbol is round on the right. --[[Special:Contributions/141.101.69.186|141.101.69.186]] 06:39, 3 August 2021 (UTC)

Right, "NORG XORT" would be a XNAND with inverted inputs, though I don't know what the logic table from a XAND or XNAND gate would look like. If De Morgan applies to XAND/XOR the same way as with AND/OR, would a "NORG XORT" then be equivalent to a XOR ? [[Special:Contributions/162.158.129.43|162.158.129.43]] 15:12, 3 August 2021 (UTC)
:: I think it is specifically a hybrid between XOR and NAND. The left edge is curved like OR, and the right edge curved like AND. I did spend some time thinking about XAND, though. One of my ideas was a >2-input AND that is only true if exactly 2 inputs are true. I wonder what qubit gates are like.

::: I could suggest "Unless" (as in 'B unless A', or maybe to counterpart 'A unless B' with standard order of operands, 'A disallows B').

236: Collecting Double-Takes

2024-02-08T22:46:36Z

Squishmallow fan: improved transcript, added category

{{comic
| number =236
| date =March 16, 2007
| title =Collecting Double Takes
| image =collecting_double_takes.png
| titletext =Fun Game: find a combination of two items that most freaks out the cashier. Winner: pregnancy test and single coat hanger.
}}

==Explanation==
There's a fairly well-founded meme that singles looking for other singles can make connections with others in the fresh produce sections of a supermarket. From a single lady's point of view, men who are buying such goods are more likely to be unattached, due to the traditionally skewed gender politics of who shops for what in a couple, and at the same time, the man is exhibiting good habits in not merely stocking up on ready-meals or subsisting on takeaways while living the bachelor life.

By standing in a produce aisle with a tube of {{w|K-Y Jelly}} (which is most commonly used as a sexual lubricant) in his hand and considering what produce to buy (between bananas, apples, oranges, zucchinis, and doubtless much more off-screen), [[Cueball]] is allowing other people to believe that he either has plans to have sex with any connection he might manage to take home with him, or also he plans to use the chosen produce item to pleasure himself, probably sexually.

Cueball is probably not actually planning on doing either,{{Citation needed}} but he loves to see the look on people's faces; hence, he's collecting double-takes.

In the title text, he says he likes to play a game of "freak out the cashier using two items." Wire coat hangers have been used to perform {{w|Unsafe abortion | do-it-yourself abortions}}, many times with disastrous effects, such as internal hemorrhaging and the death of the woman. The combination of a pregnancy test and a coat hanger will be concerning to any cashier, regardless of their opinion on abortion, for this reason; it will be doubly concerning for a pro-life cashier.

==Transcript==
:[Cueball is standing in the middle of the produce aisle in a supermarket, holding a tube of K-Y Jelly in one hand, the other on his chin. The signs read "Bananas" "Apples" "Oranges" and "Zucchini" from left to right. Megan and a Cueball-like friend are also in the same aisle.]

5: Blown apart

2024-02-08T22:27:45Z

Squishmallow fan: did no one else notice this?

{{comic
| number = 5
| date = January 1, 2006
| title = Blown apart
| image = blownapart_color.jpg
| titletext = Blown into prime factors
}}

==Explanation==
This comic is a mathematical and technical joke involving prime numbers and primary colors. In the comic, a black-colored ''70'' sees a package, but it turns out to be a {{w|letter bomb}} that explodes when opened. The result is pieces of the number scattered about: a red-colored ''7'', a green-colored ''5'', and a blue-colored ''2''.

The title text explains the logic for splitting 70 into 7, 5, and 2; as with many of the earlier comics, the title text explains the joke rather than adding to it. 7*5*2 is a {{w|prime factorization}} of the number 70. {{w|Prime number|Prime numbers}} are numbers that cannot be divided by any number other than itself and 1. Factors of a number are numbers that can be multiplied together to produce that number (e.g., 2×5×7 = 70). 70 has other factors, including 1, 10, 14, 35, and 70, but 2, 5, and 7 are the only factors that are prime. All other factors of 70 can be formed by choosing zero, two, or three of the prime factors and multiplying them together.

An implication of this comic is that prime numbers would be immune to explosions, as they are already their smallest parts. Although not explicitly called out, the colors of the numbers also seem to have been blown apart. Red, green, and blue are the primary colors in the {{w|additive color}} model. These colors mixed in pairs produce cyan, magenta, and yellow, which are primary colors in the {{w|subtractive color}} model. The removal of all additive primary colors, or conversely, the combination of all subtractive primary colors, produces black, which is the color of the original 70. The comic is somewhat misleading in that red, green, and blue do not compose black in either color model, but the difference between the two models is not widely understood (most still view the additive primaries as red, yellow, and blue).

2886: Fast Radio Bursts

2024-02-08T21:38:43Z

Squishmallow fan: helped the transcript

{{comic
| number = 2886
| date = January 26, 2024
| title = Fast Radio Bursts
| image = fast_radio_bursts_2x.png
| imagesize = 469x524px
| noexpand = true
| titletext = Dr Petroff has also shown that the Higgs boson signal was actually sparks from someone microwaving grapes, the EHT black hole photo was a frozen bagel someone left in too long, and the LIGO detection was just someone slamming the microwave door too hard.
}}

==Explanation==

[[Cueball]] is giving a presentation, stating the different sources of {{w|fast radio burst}}s, which are short high-energy signals which have been detected by astronomers, but whose sources are not known. His team is pretty sure that most of these bursts are energetic stellar objects in space - that is, astronomical phenomena.

He then says that some of them are caused by {{w|microwave oven}}s, citing Dr. Emily Petroff's work on identifying the apparent source of "{{w|Peryton (astronomy)|peryton}}s" at the {{w|Parkes Observatory}}.<ref>E.Petroff et al. (2015). "[https://academic.oup.com/mnras/article/451/4/3933/1119649?login=false Identifying the source of perytons at the Parkes radio telescope]". ''Monthly Notices of the Royal Astronomical Society'', '''451'''(4):3933–3940.</ref> These are signals similar to fast radio bursts, but which originate on Earth and not in space; initial hypotheses included atmospheric effects related to {{w|lightning}} and passing aircraft, but they were eventually identified as a much closer range signal from microwaves escaping as the oven door was opened inside the observatory.

After that, he explores two further options, combining attributes of the previous two:

* Energetic stellar-sized microwave ovens floating in space; this is unlikely since microwave ovens typically are not stellar-sized and all known microwave ovens originate on Earth rather than in space. (There is [https://global.chinadaily.com.cn/a/202106/30/WS60dbaca4a310efa1bd65ebc9.html a microwave oven] installed in the Chinese Tiangong space station, but it appears that the ISS [https://www.bbc.co.uk/news/world-51235555 is less well equipped] than that. Neither facility is ever likely to have room for 'stellar-sized' equipment of any kind.)
* An energetic stellar-sized object in the observatory break room would be surprising, as we have yet to see a break room large enough to contain a stellar-sized object. Although unlikely, he says he sends a grad student there to double-check. Presumably, the student is being sent rather than Cueball himself both because it is unlikely to give useful data, and because if there is indeed energetic stellar plasma in the break room, the million-degree temperatures would probably kill anyone who enters it, and grad students are disposable when compared to researchers.

Note that, as well as the ''universe-''sized {{w|Cosmic microwave background}} radiation, there are various microwave-bright {{w|Pulsar}}s and other strong microwave signals [https://www.space.com/40840-nanodiamonds-mysterious-cosmic-microwave-light.html originating from actual stars], but no reason to believe that they are deliberately purposed/engineered as any actual oven, despite [https://science.nasa.gov/missions/hubble/hubble-sees-a-stellar-furnace/ misleading language] sometimes employed by those in the field.

The title text references several other discoveries, with Dr. Petroff suggesting explanations based on microwave ovens for each of them, as was the case with her discovery:

* The apparent detection of the {{w|Higgs boson}} at the Large Hadron Collider was actually someone [https://www.youtube.com/watch?v=wCrtk-pyP0I microwaving grapes], which generates plasma
* The [https://science.nasa.gov/resource/first-image-of-a-black-hole/ image of a black hole] captured by the Event Horizon Telescope was a burning bagel (a notably ring-shaped bread product)
* {{w|LIGO}} (the Laser Interferometer Gravitational-Wave Observatory) did not detect gravitational waves, but was instead disturbed by someone slamming the microwave door too hard

In each case, these are highly improbable - for instance, LIGO used a complex suspension system, and two sites (one in Louisiana and one in Washington State) comparing signals, to rule out such interference.

See [[2289: Scenario 4]] for a similar situation.

899: Number Line

2024-02-07T00:01:27Z

Squishmallow fan:

{{comic
| number = 899
| date = May 16, 2011
| title = Number Line
| image = number line.png
| titletext = The Wikipedia page List of Numbers opens with "This list is incomplete; you can help by expanding it."
}}

== Explanation ==

Once again, [[Randall]] seems to be just messing around, this time with a number line.

*'''Negative numbers''' have the same magnitude as positive numbers but can only be used to represent the removal of that same magnitude (hence the term "difference" being used for subtraction). Negative numbers may be called imitator numbers in the comic because of their similarities to positive numbers.

*'''0.99'''.... is {{w|0.999...|equal to 1}} because if you subtract any number from one, however small, you will get a number that is less than 0.99. 1 − '''0.0000000372''' is 1 bit less than the {{w|IEEE_floating_point|IEEE 754 32-bit floating-point representation}} of 1.

*The '''{{w|golden ratio}}''' or '''ϕ''' (phi) is the number <math>\tfrac{1+\sqrt{5}}{2}</math>, about 1.61803. It has many interesting mathematical properties, mostly relating to geometry, and has occasional appearances in nature, such as spirals formed by the seeds in sunflowers. It is also subject to many less credible claims, such as the belief that phi appears in {{w|Parthenon}} (a well-disputed claim) or that rectangles proportioned after phi are more aesthetically pleasing. The speaker seems to drive off his listeners as soon as he brings it up; the golden ratio is infamous for being brought up by know-it-alls, which Randall has mocked in other comics.

* The approximate range from 2.1 to 2.3 is marked as '''The Forbidden Region'''. Why Randall marked this range as forbidden is really anyone's guess; it seems to be an entirely arbitrary designation.

*'''{{w|e (mathematical constant)|e}}''' (Euler's number) is 2.71828... and '''π''' (pi) is 3.14159265...

*'''2.9299372''' is probably a {{w|President's Day}} reference. It is the average of e and π just as the American Presidents' Day is always observed on the 3rd Monday of February (between {{w|George Washington}} and {{w|Abraham Lincoln}}'s birthdays). Washington and Lincoln were the 1st and 16th Presidents of the USA, respectively. Each has a celebrated place in American history.

*'''{{w|Gird}}''', '''ᛟ''' is a purely fictional number. (The glyph that Randall uses seems to resemble an older shape of the digit 4, such as seen on [http://www.bl.uk/learning/images/mappinghist/large2296.html archaic maps].). Canon and orthodox could mean "accepted as the offical story" and "most science-based followers", but they could also reference to organised religions. Gird could be a reference to any or all of:
**[http://strangehorizons.com/fiction/the-secret-number/ Bleem] - a fictional integer between 3 and 4
**iCarly's [http://icarly.wikia.com/wiki/Derf Derf] - a fictional integer between 5 and 6
**George Carlin's [http://www.urbandictionary.com/define.php?term=bleen Bleen] - a fictional integer between 6 and 7
**[https://scp-wiki.wikidot.com/scp-033 SCP-033] - a fictional "missed number" that causes mathematical systems to break down when it is introduced to them (manifesting as the physical destruction of the objects the mathematical formuli are contained in, such as paper and computers)
**Saturday Morning Breakfast Cereal's [http://www.smbc-comics.com/index.php?id=3913 Sorf] - a fictional integer between 2 and 3 

*'''Site of Battle of 4.108''' is another map joke, implying that 4.108 is an actual location, where an eponymous battle was previously fought. It may be a reference (or homage) to the {{w|Battle of Wolf 359}}, a famous military conflict in the fictional universe of Star Trek. 4.108 was also referenced in [[2861: X Value]], though with an added 3 in the ten-thousandths place.

*An '''Unexplored''' region obscures the line approximately ranging all values from 4.5 to 6.7. In the days when the Earth was still being mapped out, territories that had yet to be properly explored and charted were labelled in a similar manner. The placement of the '''Unexplored''' region on the number line indicates that all numbers in that range, including the integers 5 and 6, are completely unknown. This is, of course, patently ridiculous,{{cn}} and the humor seems to derive solely from how nonsensical and unbelievable it is. Correspondingly, the digits 5 and 6 cannot be found in the comic.

*It is often the case in the media that "It has been 7 years..." or "In the last 7 years..." etc. It is made to seem like a believable statistic but cannot always be true. Alternatively, it is intended as an absurd joke that the number 7 is just "not to be believed".

*'''8''' is not the largest even {{w|prime number}}, nor is it a prime at all. The largest (and only) even prime is 2. A joke intended for those who clearly know that the claim is false.

*The last entry seems to be a reference to certain fields of {{w|pure mathematics}}, which focus less on performing calculations with numbers and more on understanding structures that may be described using logic. It finishes off the tone of the comic that seems to be shaping the number line terms of what is commonly useful to certain areas of applied mathematics, rather than a complete, accurate version of the number line.

The title text is a literalism joke; at the time the comic was published, all Wikipedia articles with incomplete lists began with the message template "This list is incomplete; you can help by expanding it." In the case of the {{w|List of numbers}} page, one could infer the absurd notion that Wikipedia wanted to have the list include every number from negative infinity to infinity. But because all Wikipedia articles are necessarily finite, such a list would always be incomplete, no matter how much it was expanded. It may also be referencing his previous statements about Wikipedia being the home of compulsive list-makers, who make the most astonishingly complete lists imaginable.

As of 2022, Wikipedia's List of numbers page, as well as all pages including lists that cannot ever reach a state of completion, are headed by the message template "This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources."

* As for the "Gird" between 3 and 4, one might argue that the arithmetic square root of 11 may have some "integer" properties, because there exists an integer-to-integer (citation needed) function f(x) such that f(f(x))=11x. (details needed)
* The "unexplored" area is actually famous for some numbers such as "Twice Euler's constant" (also known as Tau, approximately 6.283185).

Squishmallow fan:

Okay, I have to ask this, and this as good a place as any. Am I the only one who reads Black Hat (and Danish) with an affected English accent? Anonymous 21:04, 3 December 2013 (UTC) {{unsigned ip|173.245.54.91}}
:Talk to someone in Scotland, and then some Australian, South African and finally compare Texas with LA and NY, or the London suburbs. English is still not easy, especially for non native speakers. But Black Hat and Danish are quite sure talking at some American English slangs. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 23:25, 3 December 2013 (UTC)

Firstly, is this destructive resonance thing actually possible for car speakers? (note: don't worry, I'm not going to try this myself, just wondering)... secondly, I hadn't thought about accents before. I'm English but all the characters have my own internal voice... maybe I should put some effort in and give them all different accents (wouldn't know which accents but the aforementioned affected-english for Black Hat doesn't work in my head, as good as that suggestion was). [[User:Squirreltape|Squirreltape]] ([[User talk:Squirreltape|talk]]) 14:38, 14 February 2014 (UTC)

:This is more of a theoretical scenario I guess. Fatal resonances usually builds up on a naturally repeating signal. Most music isn't that repetitive, but maybe the bass line is, which carries some momentum. If the loudspeaker elements are pushed close to their max, adding to their energy might be enough, but this energy doesn't get time to build up so it can't really be called resonance IMO. [[User:Todor|Todor]] ([[User talk:Todor|talk]]) 19:11, 5 June 2016 (UTC)

::Would this actually work though? I'm wondering what the phase-shift would have to be for the resonance to blow out the speakers, or could you just play a song with inverse sound waves in order to cancel them out?[[Special:Contributions/162.158.202.196|162.158.202.196]] 17:16, 24 January 2017 (UTC)

Maybe I should clarify: I am American and, in my part at least, British accents are considered "snooty" and "superior", a trope Black Hat would gladly take advantage of, as would Danish, for they do consider themselves vastly superior the "commoners" and "plebs" around them (why else would they be so casually sadistic?) YMMV on the stereotypes, but that is the one I am familiar with and the one I assume they use. That said I, personally, do not think the British themselves are "snooty", but am guilty of affecting such an accent when feeling snootily sarcastic. Anonymous 08:02, 26 March 2014 (UTC)

I didnt have an accent in my head for these stick figures, but now i have them talking like the people from "i love lucy," with black sounding like fred mertz.{{unsigned ip|173.245.54.167}}

Okej, he says to throw the switch labelled "Macarina", but it doesn't say that that's actually what it does. This is Black Hat we're talking about. I wouldn't trust his labeling if I were you.[[Special:Contributions/108.162.221.9|108.162.221.9]] 00:59, 8 June 2014 (UTC)

How would the machine work against the loud girlfriend/elliptical dish? It seems to me that creating a phase-shifted replica of her moans would be pretty much impossible. If it were, what would the resonance do, blow out the girlfriend's lungs? How would that feel to her? --[[Special:Contributions/199.27.128.85|199.27.128.85]] 21:37, 5 July 2015 (UTC)

:Possibly for destroying the elliptical dish. The problem this machine would not resonate with the elliptical but the GF as you stated. Maybe he just uses it to play annoying songs at them. {{unsigned|Flewk}}

:It would also have to be positioned perfectly in the elliptical dish' focal point to even work reflecting sounds back to her. [[User:Todor|Todor]] ([[User talk:Todor|talk]]) 19:11, 5 June 2016 (UTC)

I can’t help but wonder, why is Cueball so willingly helping Black Hat to accomplish his diabolical scheme? And then he follows up by commenting on how horrifying Black Hat’s actions are. So is it just because he’s so annoyed by the car speakers, or is Black Hat somehow coercing him into doing his bidding?
[[Special:Contributions/162.158.106.246|162.158.106.246]] 20:41, 28 September 2019 (UTC)

I disagree with the part of the explanation that claims that the comic must take place in the continental US. The title text doesn't specify "exactly two" border crossings; it merely implies that there is more than one. That could be anywhere in mainland (or attached-to-the-mainland-by-bridge) North America, north of the Darien Gap, except for most of Canada (from most of the population centers of Ontario, Google Maps wants to route through Michigan, for a total of three border crossings). [[Special:Contributions/108.162.221.149|108.162.221.149]] 14:18, 3 August 2015 (UTC)
:Correct. It "implies" more than one, but doesn't require it. Only that there be at least one. So they could be in Canada. Essentially anywhere on the continent (or an island connected by bridge to the mainland (e.g., Florida Keys)) north of the Darien Gap but outside Alaska. - Equinox [[Special:Contributions/108.162.238.172|108.162.238.172]] 23:15, 3 August 2015 (UTC)

It is likely that the car's owner can locate it via the Internet, via an app and location logic provided by the car's manufacturer. E.g., OnStar. {{unsigned ip|108.162.216.157}}

"At the time of the release of this comic there were no places where these cars could be used privately." That is not true, as there are no restrictions on vehicle use on private property. --[[Special:Contributions/108.162.212.7|108.162.212.7]] 16:35, 3 August 2015 (UTC)

The only US state that both borders Canada and permits self-driving cards is Michigan. Assuming that the logic in self-driving cars prevents them from driving on streets where they are not legal, the conversation would have to take place in that state (but then again, wouldn't the car know that it is not allowed to drive in Alaska?) [[Special:Contributions/162.158.92.64|162.158.92.64]] 19:38, 3 August 2015 (UTC)
:Maybe it's exactly a matter of what knowledge the car has. It ''could'' be linked up to something proprietry, or possibly a Cortana information-engine, to control a virtual "GPS fence", based on current legal and possibly licence-based limits. I'll bet it can be reprogrammed to ignore/extend such limits, though. (Which is why I'm dubious about the idea of 'hard limiting' flying drones from entering restricted airspace. A little hardware/software/firmware hacking should be simple enough for anyone who needs to get around such limits.)

Many years ago, a major oil company approached an auto research company to come up with both a means to describe as well as coordinates in that system of every fuel filling location on every vehicle. The thought at the time was that the company was seeking to create an automated filling station that could eliminate both the attendant and self-serve. It is only a matter of time. {{unsigned ip|173.245.54.5}}

It should be noted that this comic refers to a driverless car, which is very different from a self-driving car. In short, having a self-driving car means you can set the steering to keep you in your lane, the cruise control to keep you at a safe following distance, maybe even to observe red lights. It can’t make turns or really much of anything without *some* driver interaction. Driverless cars function as the comic describes; the driver enters a destination and the car goes there. It is illegal to test driverless cars on the roads of any state except Michigan. [[Special:Contributions/162.158.62.243|162.158.62.243]] 22:28, 22 February 2018 (UTC)
