3195: International Station

Ken g6: The point of this Exclamation Point

{{comic
| number = 3195
| date = January 16, 2026
| title = International Station
| image = international_station_2x.png
| imagesize = 265x250px
| noexpand = true
| titletext = Welcome to the International Space Station Exclamation Point!
}}

==Explanation==
{{incomplete|This page was created by a BOT APOSTROPHE S SPACE TRANSLATION SPACE ERROR PERIOD. Don't remove this notice too soon.}}
This joke makes fun of the parity between 'space', as in the invisible character between words, and 'space', as in the void between astronomical bodies. In this case, it is said that the word 'space' was never meant to be part of the name of the {{w|International Space Station}}, but was included as a word due to a transcription error.

The presumption is therefore that someone thought it necessary to say the name as "International (space) Station," perhaps to quash any misconception that the intended name might be "InternationalStation" (however capitalised). Someone else would have written this down as International Space Station, with the accidental name being accepted due to the resulting name being acceptably apt or inconvenient to change.

The title text furthers the joke by transcribing the exclamation mark at the end of the phrase, similar to [[3143: Question Mark]]. There were also multiple examples of strings, with punctuation (literal and otherwise) and spelling easy to misconvey in [[1963: Namespace Land Rush]], though none of them used either spaces or "space"s. The full name of "International Space Station Exclamation Point" may also sound like it refers to a location in the International Space Station by the name of "Exclamation Point", one apparently intended for making exclamations like the title text. In a similar vein, when customers order signboards, they sometime come with unintended quotation marks. The customer writes the signage text with quotation marks, with the expectation that the signmaker will ignore them.

The ISS made the news on 15 January 2026, the day prior to the release of this comic, due to the {{w|List_of_accidents_and_incidents_involving_the_International_Space_Station#2026|unprecedented evacuation of some crewmembers to Earth for medical reasons}}.

While the ISS had other names during its design, such as Space Station Freedom or Alpha, it does not appear that NASA or Roscosmos literally originally referred to it as just International Station. The Russian name for it is "Международная Kосмическая Cтанция" (MKC) or "Mezhdunaródnaya Kosmícheskaya Stántsiya", which translates as "International Space Station" using the cosmic, non-punctuation meaning of "space".

Ken g6: Clarified how I see accretion disk habitable zone

"Faint dust cloud that will cause several papers to be retracted" could refer to either Fomalhaut b (former proposed exoplanet that turned out to be a dust cloud) or Tabby's Star (star with odd irregular dimming pattern likely due to a dust cloud, but was briefly thought by some to be an alien megastructure the speculation of which caused the media to lose their shit). [[User:Erika lovelace|Erika lovelace]] ([[User talk:Erika lovelace|talk]]) 19:53, 16 June 2025 (UTC)

3028: D&D Roll

2024-12-24T17:42:16Z

Ken g6: /* Explanation */ Link to Wikipedia page with dice shapes

{{comic
| number = 3028
| date = December 23, 2024
| title = D&D Roll
| image = dnd_roll_2x.png
| imagesize = 312x313px
| noexpand = true
| titletext = Under some circumstances, if you throw a D8 and then a D12 at an enemy, thanks to the D8's greater pointiness you actually have to roll a D12 and D8 respectively to determine damage.
}}

==Explanation==
{{incomplete|Created by a D20 FORGED IN THE CAVES OF MALRON. Do NOT delete this tag too soon.}}

This comic is a scene from a tabletop roleplaying game, probably {{w|Dungeons & Dragons}}, as seen through the dialogue and title of the comic. The player [[Cueball]] announces "I roll D20... 18," referring to rolling a 20-sided die and getting the relatively high score of 18, presumably while in a fight with a {{w|kobold (Dungeons & Dragons)|kobold}} (a small reptilian humanoid creature in D&D.) The {{w|gamemaster}}, [[Ponytail]], responds that the kobold is unaffected, but humorously suggests using a sword instead, pointing out the absurdity of trying to defeat an enemy by rolling dice at them.

When you make an attacking play, a character might be equipped with a particularly obvious weapon, i.e. they only have a sword, and so the unspoken suggestion is that you wish to attack them with your sword (in the only, or most obvious, way; assuming the game also doesn't distinguish differences between different acts such as slashing, piercing, etc). But a character might have a choice, such as to throw (or stab, or slash) a dagger or, as a magic user, to cast a given offensive spell (and may have access to fireballs, blasts of ice). It may be important to know which attack is being tried against which enemy, as one that is impervious to iron or particularly susceptible to blunt trauma (whether or not the player knows this, yet) might need a player to be more specific. Assuming the choice of a D20 is not enough information (the smaller, but in this case more useful, "Icepick of Instant Kobold Death" could require a simpler 4 on a D4 to make its paralysing blow), you might have to say "I draw my elvish serrated iron sword and slash downward upon the the kobold in the leather thong <rolls a D20>... 18!", or as much of that as you need to make clear that you're not trying to attack the kobold wearing full plate-steel with a jab of the orcish wooden staff.

In this case, the possibility exists that the players' characters have actual dice, such as those which were role-played as being produced in [[244: Tabletop Roleplaying]], which may have even found impromptu combat use beyond the game-within-the-game, and so by declaring that you're rolling the dice, Ponytail accidentally/purposefully decides to understand this as which of his weapons he wishes to use for this {{w|melee}} attacks. It appears that she is gently teasing him about this, but (depending upon her GMing style) she could still insist upon this being his action. If a fairly common misunderstanding ''has'' been made, the usual reactions would be to reassess the dice roll made (as per the intended weaponry, with perhaps differing success modifiers) or else request a re-roll with the correct dice (typical of an inexperienced player). This would typically not be allowed if there are weapon/target combinations that a player is being challenged to work with, such as if the in-game dice are actually fully specified as "D20s of Orc Stunning", and the player would be expected to be taken totally seriously in his character's action (not knowing that his prior successes with the "D20s of Stunning" were only because they were made against orcs).

Given the way that this kind of meta-gaming within the comic's universe is working, it may be interpreted various ways, though the title text suggests that if you literally threw dice as weapons, an eight-sided die (D8) would indeed do more damage than a twelve-sided die (D12) because of its {{w|Dice#Common variations|pointier shape}}, so ironically, you might need to roll the D12 to determine the D8's damage and vice versa, in "some circumstances." A D20, normally being even more rounded, would therefore be one of the worst choices for 'sharpness', though may be usefully damaging through blunt-force trauma or other in-game effects.

By current D&D rules, a stone hurled from a sling does 1d3 bludgeoning damage from a small sling, or 1d4 damage from a medium sling. A sling stone typically weighs half a pound, a plausible weight for a large die made of a dense material. Presumably, an object of similar weight that's thrown "by hand" rather than with a sling would do less damage, though a heavier object might do similar damage (albeit with less range). The spell [https://www.d20srd.org/srd/spells/magicStone.htm ''Magic Stone''] enhances ordinary small stones so they do 1d6+1 damage when hurled, or 2d6+2 when striking undead creatures. Apparently, thrown dice do significantly more damage than mere stones, in xkcd.

In [[3015: D&D Combinatorics]], the same people (Cueball, Megan, Ponytail, White Hat and Knit Cap) are seated playing D&D in the same seats as this comic. In D&D Combinatorics, Cueball seems to be Randall, so it is likely that he is also Randall here. Randall has a history of portraying himself as Cueball.

2966: Exam Numbers

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

The comic depicts various similarly formatted examination questions that might appear on test papers at various points in a student's potential academic careeer. While they all share a similar feel, they are asking for different things, some of which might be considered more serious and examinable proofs of study than others.
{| class="wikitable"
|+ Exam numbers
! Exam level !! Question !! Answer
|-
| Kindergarten math || Write down the biggest number you can think of || At a kindergarden-level education, it is assumed that an individual might write down a relatively small number like 300, depending upon whether they have encountered the concept of hundreds. It might also be interpreted as "what's the highest number that you (think you) can count up to". Given the nature of a child's exuberant glee at learning about ''really'' big (but otherwise normal) numbers, they may even try an answer something like "a million billion squillion gazillion". It is not certain what criteria would be used to mark this question correct or orherwise, it may actually by a stealth question in child psychology or a question that everybody 'gets right' so long as they answer it.
|-
| Pre-algebra || Write down the value of x if x=3x-8 || 4
3x refers to the multiplication of 3 and x. 3x is a convenient shorthand.

By subtracting 3x from both sides, -2x = -8. Divide both sides by -2 to find x=4.

(Verify by plugging x=4 into the original equation. 4 = 3*4 - 8 -> 4 = 12 - 8 -> 4 = 4.)
|-
| Calculus || Write down the value of ∫_0^π x sin^2 x dx || The integral of the expression is (−2x sin(2x)+cos(2x)−2x)/28 + C. Plugging in values for x gives the result as π^2/4, or approximately 2.4674.
|-
| PhD Cosmology || Write down the Hubble constant to within 1% || The exact value of the Hubble constant is not known to this level of accuracy; it is about 2.3 * 10^-18 Hz.
|-
| Game Theory || Write down 10 more than the average of the class's answers || There appears at first glance to be no Nash equilibrium, since no matter what, there will be someone who is incentivised to change their answer to a higher number. However, since the box is of finite size, only finitely many numbers can be written - if everyone writes down a number ten less than a value that cannot be written, everyone scores nothing. There are some very large numbers that can be written succinctly, such as TREE(3), but there are only finitely many.
|-
| Postgraduate Math || Write down the biggest number you can think of || Postgraduate math students can probably think of very large numbers. However, the best answer is probably an "infinity", since depending on your definition of the word "number", infinity may be the largest possible number. But [https://www.scientificamerican.com/article/a-deep-math-dive-into-why-some-infinities-are-bigger-than-others/ some infinities are bigger than others]. This might heavily depend upon the branch of mathematics you are studying, however, as named (finite) numbers might satisfy some questioning contexts whilst the existence of a whole further set of trans-finite numbers would be important considerations in others.

1722: Debugging

2024-06-22T16:37:46Z

Ken g6: Category:Cueball Computer Problems

{{comic
| number = 1722
| date = August 19, 2016
| title = Debugging
| image = debugging.png
| titletext = When you Google an error message and it gets no results, you can be pretty sure you've found a clue to the location of Martin's sword.
}}

==Explanation==
[[Cueball]] is telling [[White Hat]] about his attempt at {{w|debugging}}, i.e. the process of finding out what is causing a given (computer) problem, which can become increasingly difficult and convoluted. In this case, Cueball had a problem with his {{w|Web browser|browser}}. His attempts to solve this problem led him to a problem with the {{w|Device driver|device driver}} for his {{w|Computer keyboard|keyboard}}. Chasing that issue, he found an unclear error message from a {{w|Utility software|system utility}}, and so on.

Cueball decides to "make a long story short" by skipping several steps he believes are boring, and he unexpectedly reveals this process has led him to find the “[[wikia:w:c:redwall:Sword of Martin|Sword]] of {{w|List of Redwall characters#Martin I|Martin the Warrior}}”, a legendary relic from the children's fantasy novel series ''{{w|Redwall}}''. This refers to the fact that a complicated riddled path was devised in the series that would lead to the sword, which is similar to the process of debugging, as it involves following clues to achieve an answer. But apart from that, they are entirely different.{{Citation needed}} This is pointed out by White Hat who states that at some point in the process he switched from the puzzle of debugging to the Redwall puzzle of finding Martin's sword. Redwall has been referenced before, most prominently in [[370: Redwall]]; where Martin and the sword can be seen; but also in [[1286: Encryptic]] and more recently in [[1688: Map Age Guide]].

The characters in ''Redwall'' are woodland animals, and Martin the Warrior is a mouse; the sword that Cueball finds is correspondingly tiny.

{{w|Googling}} an error message is a common method used during debugging, often leading to useful information. However, when there are no search results for a given message, it may mean the problem is so obscure that almost nobody had experienced it before. (See also [[979: Wisdom of the Ancients]] about getting only one result.) Or, as the title text hints, it might mean it was a hidden clue to the location of Martin’s sword.

:Cueball: Turns out it wasn't the browser-the issue was with my keyboard driver.

:[Zoom in on Cueball's upper torso as he is holding a finger up.]
:Cueball: Debugging '''''that''''' led me to a mysterious error message from a system utility...

:[Zoom out as Cueball holds up a miniature sword by the blade in one hand. White Hat turns his head around and looks at it while they keep walking.]

==Explanation==
{{incomplete|Created by a NINETIES KID WHO FELT SUN - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic seems to be set in an alternative reality where the sun's brightness rises and falls within an 11 year cycle, causing there to be complete darkness for around 10 years. The change in brightness over the cycle is due to sunspots accumulating over half of the cycle. When the sun darkens, standard sunspots appear. When it brightens, fictitious 'bright' sunspots appear in place of the old, dark sunspots.

This is probably a reference to the Solar cycle[https://en.wikipedia.org/wiki/Solar_cycle], which is a roughly 11-year cycle of changes in the sun's activity from a period of minimal levels of solar radiation, ejecta, sunspots and solar flares to maximum activity in these areas. Historically this cycle was observed by changes in the sun's appearance, which this comic exaggerates.

This would obviously be impossible{{citation needed}} as not only do sunspots cool the area of the sun where they appear, but during a dark phase, no light is coming from the sun, so the Earth would freeze. Sunspots are also not totally dark; NASA says that each sunspot on its own would glow orange brighter the full moon.[https://image.gsfc.nasa.gov/poetry/workbook/sunspot.html]

The title text indicates the effect on internet memes that this process has. During the 2010's, when '90's kid' memes were still funny, many have changed to reflect that the Earth has been dark since the 2000's, and thus only those born in the 90's and before would remember dawn.

:[Caption above the comic]:
:Ever wonder why the sun disappears for about 10 years every other decade? This terrifying period of worldwide darkness is a natural consequence of the 11-year sunspot cycle:

:[A graph with "Sunspot number" on the Y axis and "Time" on the X axis. A dashed line increases, then decreases, then slightly increases again. Above the dashed line are eight circles representing the sun with various levels of sunspots, with an arrow between each circle. From left to right: The first circle is clear. The second circle has a few sunspots.]
:Dark sunspots appear.
:[The third circle has a few more, and darker, sunspots.]
:Sunspot number rises.
:[The fourth circle has some large black sunspots with much of the remainder of the circle in gray. Between the fourth and fifth circle is a label:]
:Number falls as sunspots merge.
:[The fifth circle is mostly black. The sixth circle is all black.]
:Sunspots envelop sun, Earth enters years of darkness.
:[The seventh circle is mostly black with a few light areas. The eighth circle is still mostly black but with some larger white areas.]
:Bright sunspots appear, cycle reverses.

:[A second graph is labeled "History" but its Y axis is not labeled. The X axis has the years "1970", "1980", "1990", "2000", "2010", and "2020" labeled. The areas between 1970 and 1980, 1990 and 2000, and approximately 2012 and 2025 are labeled "Sun is bright". The areas between 1980 and 1990, and 2000 and approximately 2012 are labeled "Sun is dark".]

2721: Euler Diagrams

2023-01-07T00:51:09Z

Ken g6: /* Explanation */ Arabic numerals

{{comic
| number = 2721
| date = January 6, 2023
| title = Euler Diagrams
| image = euler_diagrams_2x.png
| imagesize = 370x409px
| noexpand = true
| titletext = Things Leonhard Euler created ( most of math ( overlapping circle diagrams ) a cricket bowling machine ) Things John Venn created
}}

==Explanation==
{{incomplete|Created by JOHN EULER AND LEONHARD VENN - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

In this comic, [[Cueball]] is showing an off-screen person a {{w|Venn diagram}} he made about something. The off-screen person then informs Cueball that it is in fact an {{W|Euler diagram}}, not a Venn diagram. Cueball then proceeds to complain that many things are named for {{w|Leonhard Euler}} (specifically {{w|Euler's constant}} and {{w|Euler's function}}) and and wants to call the diagram a Venn diagram to give {{w|John Venn}} more credit. His off-screen friend refuses, and mockingly states that numbers are now called "Euler letters", which is currently false.{{citation needed}} Modern {{w|Arabic numerals}} predate Euler by at least a century, and other numerals existed before that.

A Venn diagram is "a widely used diagram style that shows the logical relation between sets". It shows overlap of items in different categories (sets) by using overlapping circles (or other shapes) to stand in for categories. If an item is within a certain circle, it is in the category the circle represents. So in a Venn diagram of "animals" and "fuzzy things", cat would be in the overlap between both circles, frog would be inside only "animals", and "kiwifruit would only be in "fuzzy things". "Crystals" would be outside both circles. In a Venn diagram, all 'circles' must overlap with all other circles, even if there are no items in the overlap. This is easy enough for 2 and 3 sets, but as the number of sets increases the diagrams can get [https://www.newscientist.com/article/dn22159-logic-blooms-with-new-11-set-venn-diagram/ rather complicated], and the sets can start looking very non-circular. An Euler diagram only depicts the non-empty combinations, and therefore does not have this constraint.

[[File:Euler Diagrams title text.png|300px|thumb|right|The title text as a Venn diagram]]
The title text is an example of a "written" Venn diagram, with Leonhard Euler creating "most of math", John Venn creating a {{w|cricket}} bowling machine, and both of them having created overlapping circle diagrams.

:[Cueball is standing in front of a whiteboard with his palms raised. The text "Venn Diagram of" is visible in large letters, with "of" on the next line and slightly smaller. Below this are two squiggly lines representing illegible text, followed by three partially overlapping circles with a number of squiggly lines in them.] 
:Friend (offscreen): Actually, that's an ''Euler'' diagram, because-
:Cueball: Come '''''onnnn.'''''
:Cueball: '''''Everything''''' is named after Euler. Euler's constant, Euler's function.
:Cueball: Can't we let John Venn have this?
:Friend (offscreen): No.
:Friend (offscreen): Also, numbers are now "Euler letters."

2712: Gravity

2022-12-24T22:37:23Z

Ken g6: /* Celestial Bodies */ Europa has liquid underneath its surface. The Earth Eurozone doesn't AFAIK.

{{comic
| number = 2712
| date = December 16, 2022
| title = Gravity
| image = gravity_2x.png
| titletext = It's a long way down.
}}

*To experience the interactivity, visit the [http://xkcd.com/2712/ original comic].
==Explanation==
{{incomplete|Created by THE UNIVERSE FROM A PIECE OF FAIRY CAKE- Please continue expanding and describing the various bodies. Do NOT delete this tag too soon.}}
In this interactive comic, the viewer pilots a small spaceship throughout a vast area in space. The viewer is capable of exploring various bodies and planets within the play area, many containing easter eggs alluding to the book What If? 2 and previous xkcd comics. The flight mechanics are largely, if not entirely, Newtonian, so the vessel is capable of using the gravity of planets to alter its trajectory or even enter orbit. The spaceship has indicator circles around it which appear when a gravitational body comes into range, showing the direction towards their center of gravity and the size of the body. A circle also appears around the spaceship whenever it collides with a gravitational body, acting as a shield. The shield remains until the player orients the spaceship upright so its landing gear can deploy.

With a keyboard the arrow keys rotate the spaceship and accelerate it forward and backward. You can also use the standard first person shooter keys 'w', 'a', 's' and 'd', and the standard vi text editor navigation keys 'h', 'j', 'k', and 'l' to control the spaceship. Despite some ships having no unique backward texture, all ships can reverse. On mobile the comic will full screen, pressing either side of the center rotates the spaceship, and pressing in the center accelerates it forward.

It is fairly easy to fly between planets as long as you pay attention to orbital mechanics; don't just floor the accelerator. The background stars show your velocity and orientation relative to the nearest gravity well. If you are having difficulties navigating space, point towards a gravity orb and accelerate for only a few seconds. Wait until the background stars spin wildly, and then reduce your velocity to 0 before gently accelerating towards the object.

'''Playing on mobile:''' Various additional glitches may occur. Having a starting position slightly below the take-off pad means you're already 'glitched' inside the planet from the off. Escaping the planet may need inverted 'accelerating' (turning perpendicular to the local vertical, and thrusting ''backwards'' until you can glitch back out into more open space. You may also be trapped within the cannonball 'orbit', with seemingly inconsistent collision-detection, such that you can be sat ''with landing gear extended'' upon features (projectile tracks, etc) that seem not to count as solid for most other purposes.

There is no "universal" point of view — the bottom of the window, "down", is oriented towards the object exerting the most gravity upon the player. Multiple things found in this comic draw attention to this, such as how on Earth Ponytail says to White Hat, "I checked downforeveryoneorjustme.com and it says just me", and he replies "Yeah, I guess down isn't down for everyone."

Throughout the play area are coins that change the spaceship into different rockets and non-space based vehicles, including humans.

The comic promotes Randall's new book [https://xkcd.com/what-if-2/ What If? 2], which was released in September and is available for purchase. Many of the planets contain references to various What If? articles.

The comic is similar to [[1608: Hoverboard]], which celebrated Thing Explainer instead.

'''Click to expand:''' 

<div class="mw-collapsible mw-collapsed leftAlign" style="width:100%">
 
*'''Speedhack:''' <code>ship.engines = "warp"</code> - Speed hacking, sets speed to 1.4x. set to "standard" to reset to normal speed
*'''Teleport to planet:''' <code>[Comic.voyager.pos.x, Comic.voyager.pos.y] = Comic.planetRects.'''''origin'''''.slice(0,2)</code> - teleport near a planet, in this example near earth. You'll still have to fly a bit towards the nearest planet to reach it. Replace '''''origin''''' with the ID of the planet you want to go to, from the table above.
*'''Teleport to coordinate:''' <code>[Comic.voyager.pos.x, Comic.voyager.pos.y] = '''''[0, -2000]'''''</code> - teleport to an exact coordinate. <code>[0, -2000]</code> happens to take you to the starting area.
*'''Improved radar:''' <code>Comic.wayfinderFarDistance = Infinity</code> - make the direction of all objects visible. This can be hard to understand though.
*'''Chaos Mode:''' <code>ship.engines="infinite improbability drive"</code> - Seems to randomly teleports the ship. A reference to its namesake in Hitchhiker's Guide to the Galaxy.
*'''Insta Death:''' <code>ship.shields = false</code> - Kill the player if they land on a planet, the code never sets it to false, so it seems to be always true.
*'''No Clip:''' <code>noclip = true</code> - Enables noclip. Also disables gravity.
*'''Select ship:''' <code>Comic.ship = "ship-tintin"</code> - Select ship (use filename from list of ships)
*'''Autorotate:''' <code>Comic.cameraRotation = false</code> - View does not rotate with ship
*'''Goggles:''' <code>ze.goggles()</code> - returns a warning: "they do nothing!". This is a reference to Hoverboard, where ''ze.goggles()'' would give you the ability to see false walls. Which itself is most likely a reference to the Simpsons where Radioactive man complains that his safety goggles do nothing against a deluge of acid.
*'''Python:''' <code>python("import antigravity")</code> - reverses gravity, so the ship falls away from planets. A reference to [[353: Python]]. Reset with <code>Comic.gravityConstant = 100</code>.
*'''Light Mode''' <code>Comic.lightMode = true</code> - inverts the color of the comic. reset with <code>Comic.lightMode = false</code>
</div>
 

==Trivia==
The objects in the mini-universe of this browser game are all at fixed positions and do not interact through gravity, however, the ship controlled by the player is affected by gravity. While this makes it technically a relatively easy integration problem (of the position of the player ship forward in time), the integrator used seems to be a relatively simple one - and certainly not a symplectic one, because it does not conserve angular momentum. This can be seen when one manages to get into orbit around some object, e.g. the core of the sun. The orbit slowly decays over time.

The logic for extending the landing legs and landing is rather simple. A ship can (normally) land if it is facing away from the surface it collides with, and if its momentum is more-or-less directed towards the surface. Once landing is triggered, the ship will rotate to face directly away from the object exerting the most gravity on the player, regardless of how sloped the surface is. The only way to get into space again is to accelerate forwards, as neither turning nor accelerating backwards cancels the landed state. All of this can be abused to land on almost everything. To land on the underside of an object, simply point your ship away from the object and slowly accelerate backwards to counteract the force of gravity. Landing on the side of an object is more difficult, as ships cannot accelerate sideways. The first method is to accelerate backwards to launch yourself upwards and towards the object so that at the top of your arc you will collide with the object. Then, rotate your ship accordingly to land. Method two is to just repeatedly slam your back of your ship into the object until you land. Note that with any of these weird landing methods, your ship will turn to face away from the source of gravity and can clip into objects.

Executing <code>window.python("import antigravity")</code> or <code>python("import antigravity")</code> as Javascript on the page will reverse gravity, multiplying the gravity constant by -1.

Executing <code>window.ze.goggles()</code> or <code>ze.goggles()</code> as Javascript on the page will show a warning in the console: "<code>they do nothing!</code>"

Talk:2669: Things You Should Not Do

Ken g6: Painting of the Sahara Desert - it's been done!

Seems like this could become a series. [[Special:Contributions/172.68.210.31|172.68.210.31]] 20:42, 7 September 2022 (UTC)
:Maybe. But I don't think it will be.
:What I was thinking was that there are clearly, on average, around 43  items per 'page', up to this point. This page shows only 19 items (both pre-New and New, or 20 if the "New" line counts as one, don't know if multilines reduce the number of numbered items ler page), so either it's been{{Citation needed}} manually split/new-paged (for changing aesthetics) or else it is highly varying according to the font-height/multiline-wrappings in use beforehand. Or perhaps we should expect around the same number of 'newer New' items to complete this page before the next page number is automatically started to be populated. [[Special:Contributions/172.70.86.8|172.70.86.8]] 20:53, 7 September 2022 (UTC)

<nowiki>#156,819</nowiki> looks like a reference to the Phineas and Ferb title sequence, and the episode Oil on Candace and probably more relevant here, What If 84. [[Special:Contributions/108.162.210.233|108.162.210.233]] 21:49, 7 September 2022 (UTC)
:It's true that it could be a reference, but I think I recognized most of the topics on the list as being mentioned in some what-if article from the archives--in the case of the "painting" one, https://what-if.xkcd.com/84/. [[User:Dextrous Fred|Dextrous Fred]] ([[User talk:Dextrous Fred|talk]]) 22:13, 7 September 2022 (UTC)
::I think that given that he learned about this doing his new book that has not been released yet most of the new items would first be clear when we read the book, and hence all references to old what if seems moot to me... In my opinion it seems that those writing the current explanation failed to read this sentence: ''Updates to my "Things You Should Not Do" list, based on what I learned writing What If? 2''!!! Taking this into acount nothing on the new list shoul dbe from the old what if blog/book. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 13:02, 8 September 2022 (UTC)
:I think <nowiki>#156,819</nowiki> is confusing because [https://commons.wikimedia.org/wiki/File:Gustave_Guillaumet-_Le_Sahara.jpeg it's been done]. -- [[User:Ken g6|Ken g6]] ([[User talk:Ken g6|talk]]) 17:01, 8 September 2022 (UTC)

Added a transcript, hopefully it isn't too terrible. (also first explainxkcd edit!) [[User:Merrybot|Merrybot]] ([[User talk:Merrybot|talk]]) 21:52, 7 September 2022 (UTC)

Any indication what the purpose of the misspelling of ''hemorrhagic'' as ''*hemorraghic'' might be? XKCD is usually typo-free, which makes this look deliberate – but why? [[Special:Contributions/172.71.94.3|172.71.94.3]] 00:29, 8 September 2022 (UTC)
:I assume just a typo by Randall Munroe. [[Special:Contributions/172.70.214.79|172.70.214.79]] 02:11, 8 September 2022 (UTC)
::"XKCD is usually typo-free" Oh, they do happen every now and then but usually get corrected eventually by Randall. Nothing too special about this. [[User:Elektrizikekswerk|Elektrizikekswerk]] ([[User talk:Elektrizikekswerk|talk]]) 07:13, 8 September 2022 (UTC)

<nowiki>#156,823</nowiki> is actually a subplot in the movie "Only Lovers left Alive" by Jim Jarmusch. {{unsigned ip|162.158.129.163}}

<nowiki>#156,820</nowiki> sounds like a reference to TF2's "Meet the medic" which starts off with The Medic describing how he lost his medical licence by stealing a patient's skeleton {{unsigned ip|108.162.241.103}}

2641: Mouse Turbines

[[Beret Guy]] and [[Megan]] are walking during the summer, where Beret Guy expresses his appreciation for typical features of a summer day. Though, considering the rest of the comic, Beret Guy could mean there are {{w|Cloud computing|large (or popular) server farms}} [[908: The Cloud|somewhere]] and that the bugs are {{w|Zoom (software)|video chatting}}. He also mentions "wind turbines" put up by field mice, which Megan initially assumes to be referring to {{w|Taraxacum|dandelions}} (similar to the wordplay that Beret Guy utilized in [[1322: Winter]].) However, Beret Guy turns out to be speaking literally, as he picks up what is in fact a tiny {{w|wind turbine}}, says to [https://www.dandelionpress.com/dandelion-blog/2015/4/6/how-to-wish-on-a-dandelion make a wish,] and blows into it. This causes the blades of the turbine to spin rapidly, generating a lot of power for the structure it is connected to, thus causing a field mouse to cheer in excitement.

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

Further frustrating mouse use of wind power, {{w|Wind gradient|windspeed increases logarithmically with height}} above ground. Windspeed is reported as its value 10 meters above ground, where it is 1.5 times faster than at ground level.[https://www.nooutage.com/wind.htm] In the U.S., where Randall lives, average year-round windspeed is about 15 km/h,[https://sciencing.com/average-daily-wind-speed-24011.html] or about 2.8 m/s at ground level, yielding only 0.11 watts from such turbines. However, a typical adult mouse weighs 25 grams,[https://web.jhu.edu/animalcare/procedures/mouse.html] compared to about 81 kilograms for humans in the U.S.,[https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3408371/] so presumably mouse electricity needs would be about 0.03% of people's.{{Dubious}} The average U.S. residential customer uses 1,242 watts of electricity,[https://www.electricchoice.com/blog/electricity-on-average-do-homes/] 0.03% of which is 0.37 watts. Therefore, three such turbines could be able to serve about 89% of a mouse's needs. While this figure does not account for necessary {{w|home energy storage}} efficiency (92.5% for the {{w|Tesla Powerwall}}) overhead, mice usually live much less extravagantly than typical Americans,{{citation needed}} so three turbines per mouse should be sufficient.

The title text builds on the similarities between small wind turbines and dandelions by claiming that turbines reproduce by dispersing their blades, in the manner of dandelion {{w|seed dispersal}}. Randall's suggestion of turbine seeds conflicts with Beret Guy's assertion that the turbines were built by field mice.

Talk:2641: Mouse Turbines

2022-07-05T04:48:41Z

Ken g6: Who is Beret Guy telling to make a wish - Megan or the mice?

Is anybody going to try to calculate the amount of power such a turbine could collect? -- [[User:Dtgriscom|Dtgriscom]] ([[User talk:Dtgriscom|talk]]) 19:24, 4 July 2022 (UTC)
:Good idea; what should we use for an estimate of the geometry for https://www.omnicalculator.com/ecology/wind-turbine ? The final panel makes it look like the blade diameter is about twice the size of a fist. [https://www.sciencedirect.com/science/article/pii/S2215098616300830] says "exhaled air velocity varies from 2.2 m/s to 9.9 m/s (5.66 ± 1.57 m/s, mean ± SD) and exhalation time varies from 2.10 s to 8.21 s (4.42 ± 1.73s, mean ± SD)."
:I guessed 10 cm radius and used that mean breath speed. I should have used the top 9.9 m/s though, shouldn't I? [[Special:Contributions/172.70.214.185|172.70.214.185]] 20:56, 4 July 2022 (UTC)
:After a closer look at that article, the mean is more appropriate. [[Special:Contributions/172.70.206.95|172.70.206.95]] 21:19, 4 July 2022 (UTC)

Although these miniscule wind turbines don't generate much power, mice probably don't need much. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 21:17, 4 July 2022 (UTC)
:That's certainly a fair point. How much power would a mouse-sized fridge need? [[Special:Contributions/172.70.206.95|172.70.206.95]] 21:23, 4 July 2022 (UTC)

Someone please check my mouse energy needs math and assumptions. I made a couple misplaced decimal mistakes getting to where it is now, and I'm going to have another beer. [[Special:Contributions/172.70.211.52|172.70.211.52]] 22:17, 4 July 2022 (UTC)

I'm confused by the statement that smaller turbines are less "efficient". There's nothing about efficiency at that link. [[Special:Contributions/172.70.114.43|172.70.114.43]] 22:33, 4 July 2022 (UTC)
:The graph shows the ratio between size and output has risen from about half to 85%. What is a better term for this? I'm pretty sure one of the multiple definitions of efficiency is technically correct, but it can never hurt explaining better. [[Special:Contributions/172.69.33.113|172.69.33.113]] 22:42, 4 July 2022 (UTC)
:Changed to "relative power output" but I'm not sure that captures the idea very well either. [[Special:Contributions/172.69.33.113|172.69.33.113]] 22:44, 4 July 2022 (UTC)

Well wind turbines may not scale down ideally but still better than nuclear power plants. I suspect those have fixed minimal size and it's pretty big. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 23:32, 4 July 2022 (UTC)

:Apparently nuclear power can be [https://technology.nasa.gov/patent/LAR-TOPS-294 "as small as a button cell"] but mice are vulnerable to radioactive hazards, and haven't solved the waste disposal problem. [[Special:Contributions/172.70.214.185|172.70.214.185]] 23:45, 4 July 2022 (UTC)

Isn't the power output of a solar panel directly dependent on its size (and wether it's covered with snow, angle to the sun, clouds? And prolly something I'll think of as soon as I hit save).[[Special:Contributions/172.70.131.106|172.70.131.106]] 23:55, 4 July 2022 (UTC)

What is the smallest Tesla Powerwall available for purchase? [[Special:Contributions/172.70.206.163|172.70.206.163]] 02:00, 5 July 2022 (UTC)

2536: Wirecutter

2021-11-02T21:38:44Z

Ken g6: /* Explanation */ Wikipedia's List of religions and spiritual traditions: a wide variety of religions

{{comic
| number = 2536
| date = November 1, 2021
| title = Wirecutter
| image = wirecutter.png
| titletext = This was always going to be a controversial Wirecutter post, but what really got them in trouble were their 'budget' and 'upgrade' picks.
}}

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

''{{w|Wirecutter (website)|Wirecutter}}'' is a product review website owned by ''The New York Times''. Randall is parodying the website by having them "review" the 70 most popular [[:Category:Religion|religion]]s. Product review websites typically make posts with the "best" X, e.g. "Best smartphones", or "Best laptops". These reviews are useful for consumers trying to choose among the wide variety of products available.

There is also {{w|List of religions and spiritual traditions|a wide variety of religions}}.{{fact}} However, unlike electronic devices, a person does not usually choose their religion; they are taught one during childhood and most remain in that religion their entire life. Changing religions is a significant life event. More specifically, many variants of the three major {{w|Abrahamic religions}} promote {{w|Religious exclusivism|exclusivity}}, and do not recognize other religions as valid. They emphasize the importance of belief in specific creeds. Members of those religions might not recognize a reviewer as having truly "tried" their religion if their intent was always to move on to another.

A post "reviewing" religions is sure to stir up controversy, as most religious followers are passionate about their religious beliefs and don't want to be compared against other religions. {{w|Religious_war|Literal wars}} have been fought over the idea one religion could be superior to another, and it is not a wound most practitioners are willing to reopen any time soon. Moreover, religions are typically chosen for more fundamental reasons -- such as by comparing the likelihood that each religion makes accurate claims, or the efficacy of each religion in promoting an ethical life, or the connection a practitioner feels to the religion's rituals, metaphors, and images, or by privileging a preexisting cultural or family connection to a particular tradition -- not by comparing gimmicky features or price.

The title text mentions "budget" and "upgrade" picks, which are subcategories for reviewers - cheaper options and options that are good for upgrading your current product to a newer one. Neither of these categories are typical categories for religions {{Citation needed}} and would further anger their adherents. The idea of paying for religion brings to mind {{w|tithe|tithing}}, {{w|televangelism}}, {{w|indulgences}} and {{w|Prosperity theology}} - highly controversial practices.

Talk:2534: Retractable Rocket

2021-10-28T04:24:46Z

Ken g6: Space fountain in the rocket?

However it is done, note that the base of the 'first stage' extends/retracts in advance of the bit further up, as can be seen by the panelling position in the standing/extending/extended/retracted frame-sequence. Which might be worth noting if you're wanting to copy the technology. [[Special:Contributions/172.70.85.185|172.70.85.185]] 03:09, 28 October 2021 (UTC)

: I think this might be theoretically possible, ignoring the apparently topological outer skin of the "rocket", with some kind of steerable [https://en.wikipedia.org/wiki/Space_fountain space fountain]. Accelerating the astronauts at 10g for about two minutes might be survivable, and could limit the overall length to just over 800 miles. Though the shroud only has to extend to where the atmosphere is "sufficiently" thin. No idea whether this kind of design would tend to fall over when finished or not. -- [[User:Ken g6|Ken g6]] ([[User talk:Ken g6|talk]]) 04:24, 28 October 2021 (UTC)

If (as it appears) the Bot created the page with various references to "Retract'''i'''ble" rarher than "Retract'''a'''ble", does this mean Randall made that error initially? (I say this as the guy who failed to notice he'd put "re'''su'''able" in his Transcript edit. ;) ) [[Special:Contributions/172.70.162.129|172.70.162.129]] 03:54, 28 October 2021 (UTC)

: Looks like yep, Randall originally made that error persistently, as the image here still has "retractible" in the comic, but the image on xkcd.com has been updated. Not sure how this is usually handled, I think it's mentioned in the FAQ. [[User:Esogalt|Esogalt]] ([[User talk:Esogalt|talk]]) 04:02, 28 October 2021 (UTC)

==Explanation==
{{incomplete|Created by a THUMBTACK USER - Expand, add title text.}}
{{tvtropes|StringTheory|In many media,}} crimes are solved on bulletin boards. "Leads" are connected to each other using string, in order to sort out connections and possibilities. [[Beret Guy]], eccentric as always, manipulates this by making just such a setup solely to determine where to buy the thumbtacks and string for use in it. The joke is that the bulletin board is entirely self-referential -- without a need for thumbtacks and string to hold things on the bulletin board, there would be no need for the bulletin board itself.

The title text continues the self-reference theme: Without a need to display a receipt, there would be no need for a tattoo of the receipt.

2118: Normal Distribution

2019-03-01T15:35:57Z

Ken g6: /* Explanation */

{{comic
| number = 2118
| date = March 1, 2019
| title = Normal Distribution
| image = normal_distribution.png
| titletext = It's the NORMAL distribution, not the TANGENT distribution.
}}

==Explanation==
{{incomplete|Created by an ANNOYED STATISTICIAN. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}
In statistics, a distribution is calculated by finding how much of a sample falls into discrete bins. For example, an age distribution would often take bins of ten years (0-9, 10-19, etc.) From this a statistician often produces a bar chart, one bar for each bin, where the height of each bar represents a count of the portion of the sample matching that bin. It is common to mark standard deviations on a distribution, indicating what proportion of a sample falls into the bins between two points on the x-axis.

Many statistical samplings form a pattern called a "normal distribution". A theoretically perfect normal distribution would have an infinite sample size and infinitely small bins. That would produce a bar chart matching the shape of the curve in the comic.

The comic treats the normal distribution curve as a mathematical function and finds two lines delineating an area under that function. While this is perfectly correct mathematically, in terms of statistics it makes no sense. Since this curve is like a bar chart with infinitely small bars, this is like cutting sections out of a bar chart for no apparent reason. It has no apparent statistical meaning.

2108: Carbonated Beverage Language Map

| title = Carbonated Beverage Language Map

}}

==Explanation==
{{incomplete|Created by ONE GUY IN MISSOURI. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}

In the US, people in various parts of the country refer to carbonated beverages by {{w|Names for soft drinks in the United States|different names}} such as Soda, Pop, Coke, etc. Generally, the West Coast and Northeast say "Soda", the South says "Coke" and the rest of the country says "Pop".

There are various maps of the name differences, including: [http://www.popvssoda.com/]

This map leverages xkcd's mockery-maps of regional and state-by-state differences or variations in the use of language and overlays the regional variances in the terms for soda pop (for example: https://laughingsquid.com/soda-pop-or-coke-maps-of-regional-dialect-variation-in-the-united-states/), as was made trending and popular in 2013. Not only are there far more terms than are actually used by Americans, many are terms for other drinks (mead), unrelated liquids (quicksilver), or copyrighted beverage names less popular than Coke/Coca Cola (Code Red) -- and in one case, something that's not even edible ({{w|cryptocurrency|"Crypto"}}).
