172.70.131.52: I think xkcd fans in general love venn diagrams and are eligable.

<noinclude>{{notice|This site is intended to explain the technical details and inspirations (perhaps humorous) behind the comics. This particular page is for Discussion/Talk about the particular comic in question, which ''will'' involve some personal overviews and meta-discussion. But it is not the ideal place to reproduce the wider issue of public opinion, which the actual political process will eventually establish, and many other public forums and outlets exist in which you can convey your own current leanings/observations on the whole election-related happenings. Please be <s>sensible</s> ''typically geeky in your wit'', and try to keep all the ideological heat and partisan arguments out of this as much as possible.|image=warning!!.png|}}</noinclude>

Another really timely comic. Biden just dropped out of the race and endorsed Harris yesterday. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 01:58, 23 July 2024 (UTC)

Forget Biden, Hillary and Obama. This is the endorsement that counts. [[Special:Contributions/172.68.23.199|172.68.23.199]] 01:58, 23 July 2024 (UTC)

I suppose no one is allowed to say that the upper right circle is mislabeled. It was supposed to say incompetent, dishonest and despicable. [[Special:Contributions/162.158.90.25|162.158.90.25]] 02:07, 23 July 2024 (UTC)
:You're allowed to say it, but then we're allowed to suggest (with rather more emperical proof) that her presumptive opponent better fits your rewording. How about we all just don't try to re-run the old arguments (or pre-run the upcoming election) in that sort of tone, eh?
:(To be clear, Randall has made positive comments to his favoured candidate, rather than stooping to arbitrarily attacking their opponent. If you can't at least be as positive in your own convictions then it's really not going to help your cause.) [[Special:Contributions/172.69.195.6|172.69.195.6]] 04:10, 23 July 2024 (UTC)
::First, Harris has more than one opponent, not just within her own party, but in the general election to follow if she’s nominated. Second, the many good qualities of my favo[u]red candidate are irrelevant to this comic, so I didn’t mention ''her''. Third, I didn’t start this political discussion; Randall did, by making a refutable claim in his comic. Lastly, there’s nothing arbitrary about a resident of California pointing out [https://truthout.org/articles/kamala-harris-has-a-distinguished-career-of-serving-injustice/ facts about the former attorney general of California] that people in other states, such as Massachusetts, might be completely ignorant of.

Randall angling for VP? [[User:Alcatraz ii|Alcatraz ii]] ([[User talk:Alcatraz ii|talk]]) 02:59, 23 July 2024 (UTC)

The layout of this Venn diagram reminds me of https://xkcd.com/112/ {{unsigned ip|162.158.166.234|03:04, 23 July 2024}}

I think I would probably swap the two. [[Special:Contributions/162.158.174.23|162.158.174.23]] 04:03, 23 July 2024 (UTC)

I would be very interested in which non-Politicians Randall would put into the top middle section. [[User:Fabian42|Fabian42]] ([[User talk:Fabian42|talk]]) 04:35, 23 July 2024 (UTC)

I guess Munroe has no issues with questions about ongoing U.S. backed genocides shrugged off with "shrimp and grits!"? {{unsigned|Markifi|05:39, 23 July 2024}}

What really strikes me is that the USA have a (de facto) 2-Party system and still go so much into personal attacks and endorsements, etc. which in my mind could be the decision-making bit between 2 similiar parties in a multi-party system, or 2 equally sympathic parties to me. But in my mind a 2-party system should at least have the upside of actually discussing policy, and voters deciding based on that... --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 06:30, 23 July 2024 (UTC)

If Randall was in charge he could stop supplying weapons to Israel probably [[Special:Contributions/172.69.195.63|172.69.195.63]] 10:16, 23 July 2024 (UTC)

172.70.131.52: /* What if 2 planet */ new section

Whatever image is supposed to be in the center isn't showing up for me! D: Tried on both Safari and Chrome but it gives me the little broken picture icon. Hopefully it's fixed soon! (The comic's been up for about 10 minutes going by when the bot updated this page.) [[Special:Contributions/172.70.126.117|172.70.126.117]] 22:28, 16 December 2022 (UTC)

: The center image is trying to load this link, but there's nothing there: https://xkcd.com/tile/ship1/ship_gliding_2x.png. I hope that gets fixed soon. The "ship" seems to rotate a bit unpredictably over time. At first I thought it was responding to my mouse movements, but I don't think so anymore. [[User:Orion205|Orion205]] ([[User talk:Orion205|talk]]) 22:34, 16 December 2022 (UTC)

: Ah, the center image is controlled by the javascript, of course: https://xkcd.com/2712/comic.js. So this is some sort of interactive comic? [[User:Orion205|Orion205]] ([[User talk:Orion205|talk]]) 22:36, 16 December 2022 (UTC)

You can transform the ship into a different (seems faster to me) one by running into the last cannon ball.

Rough summary: The comic is an interactive space flight game, starting landed on an origin planet. The planet is static, and the player starts in a ship controlled by WASD or Directional keys. The ship can go up and down, and rotate left and right. Game simulates orbits and gravity, making navigation tricky. Around the player ship there are dots which indicate nearby planets - there are numurous planets, each with what seem to be drawings related to the What If book. Within the browser, planets are loaded in PNG format by chunk, names formatted as "planet_0_0" with numbers incrementing as grid co-ordinates. Planets and objects found: "origin" "europa", "road", "b612". NOTE: Several hazards exist, such as a field of black holes - if flown into, the ship can become stuck if let to be pulled close to the surface, locking in place. [[Special:Contributions/172.70.110.230|172.70.110.230]] 23:13, 16 December 2022 (UTC)

: Within browser dev console exists the objects "Ship" and "Comic", the latter containing a list of all objects and coordinates, as well as various setting for the game physics and settings. Comic contains the sub-object "Voyager", which contains the details and settings for the player ship, including location, speed, etc. [[Special:Contributions/172.70.110.230|172.70.110.230]] 23:13, 16 December 2022 (UTC)

:: There are 5 ship types in the game code, each with their own consumable transformative found in the world. The ship alternatives are (ship1, ship2, ship-tintin, ship-figure, ship-soccerball). These can be changed with console command [Comic.ship = "ship1"]. Note: At current, "ship-soccerball" returns an error and does not load correctly. [[Special:Contributions/172.70.110.230|172.70.110.230]] 23:13, 16 December 2022 (UTC)

:: The "ship.shields" is a boolean value that defaults to true, and when set to false, makes the game behave in a lunar lander mode (bad landing black screens the whole page). The "ship.engine" types I see in the code are "warp" (very fast speeds) and "infinite improbability drive" (teleports to 'improbable' places). Default engine is "standard", but it seems any value that is not the former two has the same effect. --[[Special:Contributions/172.70.254.165|172.70.254.165]] 23:32, 16 December 2022 (UTC)

: In addition to Europa, the space road, and B-612, there is the "Edge of the Universe" (complete with Milliways restaurant nearby), a... tree (which is extremely hard to land on), a planet populated by the characters from Dinosaur Comics (and the main cast of Jurassic Park), the USS Enterprice (NCC 1701-C), and likely quite a bit more. Orbital mechanics make it tough to land on the smaller targets. [[Special:Contributions/172.71.254.46|172.71.254.46]] 23:07, 16 December 2022 (UTC)

:: Plus what appears to be Earth, complete with the LHC. There's a 2nd "cannonball" there for an additional ship upgrade, but at the time I found it, that graphic was unavailable. [[Special:Contributions/172.70.126.232|172.70.126.232]] 23:15, 16 December 2022 (UTC)
:: "Edge of the Universe" is part of "Outside". There is a hidden tunnel from the main universe to the bubble universe at coordinates (7597,24327) point nose of ship at words "EDGE OF THE" and fire thrusters. [[Special:Contributions/162.158.79.160|162.158.79.160]] 03:59, 17 December 2022 (UTC)

: I went out a long ways away, and eventually found The Great Attractor. It attracts really hard. I couldn't leave the surface. (I wasn't able to leave the center of Europa either, though, so, not saying much.) There are also some terrifying black holes (a binary system?), though something's weird about their gravity; you kinda bounce off of them a quarter screen away or so?

:: I *think* thats a wormhole, you go in one and then out the other. I got stuck right between them. Speaking of getting stuck, there is a bug where if you hit a planet with enough gravity fast enough, the ship is inside the planet. Holding W makes you go backwards (or at least towards the center maybe?) and you can get all the way to the other end of the planet where you slow down a lot, but can eventually leave.

::There's one planet that's supposed to be the "remnant of the sun", is that what you mean with The Great Attractor? (It has a bridge on it with a coin(?) blocking part of the way, and a space ship actively crashing into its surface, drawn as several frames.) You can leave that by skidding over the surface like a skipping stone to gather momentum - it's tricky, due to various obstacles, but possible! (It's possible you need two ship power-ups?! If they're indeed power-ups and not just aesthetic changes, I didn't pay attention.)

Using a tablet (no keyboard, but seems to respond to touch), controls are confusing. Presuming that touching bottom left activates left-rotate and touching bottom right does right-rotate (can't see the presumably white-lije controls over the white planet) but I can't get ''thrust'' anything but 'reverse' into the planet centre. No obvious top-edge hotspots, either. Maybe I need to do a "You will not go to space today" and then reverse ''upward''... BRB, after a bit more testing, though...

:Ok, the next go went 'better'. The browser keeps wanting to load "simplified content", but if I ignore that I can get full-screen, at one point I changed rocket-type (no idea how, can't do it again) and I ''easily'' get off the planet (hard to thrust just enough to get to the Hooke comment/cannon), with plenty of targets coming in range (but cannot slow down enough to not have it glitch and rebuild a totally new set of targets that I never can reach).

Using the developer console, the ship can be teleported to different coordinates via console command [Comic.voyager.pos.x = 0, Comic.voyager.pos.y = -1461], provided here with start location coordinates. This can be used for manual navigation to known coordinates. List of locations per game code added below, append landing X,Y to each as determined.

Note: For ease of teleportation, reference the ''Comic.planetRects'' array and use the first two numbers as X,Y. This will get the ship close enough to the object to then land and determine a landed location, via ''Comic.voyager.pos''

In your developer console, enter <code>window.ship.engines = 'infinite improbability drive'</code> and pressing up will randomly teleport you to interesting places.
<code>window.ship.engines = 'warp'</code> will let you escape normally inescapable objects.

Unfortunately, the infinite improbability drive will sometimes result in an object's image and geometry failing to load. The same bug can occur with a manual teleportation too close to an object. For convenience, here are a list of coordinates which put you relatively close to various locations, but far enough away to trigger the object's loading:
'''Major Locations:''' origin: (0, -1500); dogplanet: (2480, -23484); earth: (28720, -36912); europa: (26360, 984); goodhart: (-26600, 2424); greatattractor: (-594000, 247952); qwantz: (22120, -51788); remnant: (39240, -9648); soupiter: (-16000, 16032); steerswoman: (-70140, 2952); sun: (-29900, -32352); Bubble Universe: (5000,21000);

Also, I found the following javascript function helpful for teleporting around. <code>function tp(x,y){ Comic.voyager.pos.x = x; Comic.voyager.pos.y = y; Comic.voyager.pos.vx = 0; Comic.voyager.pos.vy = 0;}</code> --[[Special:Contributions/172.70.126.233|172.70.126.233]] 03:06, 17 December 2022 (UTC)

If anyone wants to download the planet images, they're at https://xkcd.com/2712/tile/<name>_i_j.png, for i,j = 0, 1, ..., going as high as needed for the planet size. For example, https://xkcd.com/2712/tile/origin_3_3.png gives the bottom-right part of the start planet.

; Proposal
It seems the most explanatory thing we can do is replace the blank starfield with the starting image screenshot, and label its four corners with their x and y coordiates, and then make a table of all the objects with their coordinates, a screenshot, and a description of their behaviors.

Alright, fixed. A few things I'm thinking about to do next, but I don't have time for:
1. Add gravitation attractions in a new column. They're all in the json dump, I suggest using a json viewer for more convenience. Or doing some coding?
2. Add item locations. This one is important, as items are a major feature.
3. Organize the items, either by alphabetical, or by distance from Earth. This might be hard...
4. Get details in! We need more information. This is the most important by far, get to work! haha.

Hi all, first time poster so sorry if I'm formatting this wrong. I found a planet at (46070, 37936) which doesn't seem to be listed yet, and I didn't see it in the comics.js output or the google drive link from [[User:Clam|Clam]].

I wish to note that I'm using Safari on an iPad, which usually can't touch the interactive comics (I know hoverboard was a whole lot of nothing), for this one I can turn the rockets on and off, that's it. Seems like my path is predetermined, on autopilot (turns here then there, first time in an S, with nothing in sight to be modifying my flight). The first time I was going pretty fast, rockets off, then I turned them back on right before I blasted past SOME planet, flitted by in a blink, so I'm hoping to find it again, but I have no control except Thrust or No Thrust.

:Check that, NOW if I tap the left side I get the right thruster and vice versa! Hey, I have control! [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 07:24, 17 December 2022 (UTC)
::Found Jurassic Park planet and Dog Park planet, then found the sun, saw SOMEBODY saying something but I skidded to a stop too far away, and no, escape is NOT possible. I'm in the default rocket and turning on the thrusters just gives a little hop, not enough to then tun on ONE thruster to actually change position. I am unquestionably STUCK, LOL!

;Cosmic topology?
Does space wrap around horizontally and vertically in a torus like the Atari ''Asteroids'' video game, or does it go on forever in all directions? If the former, how many times the area of the initial comic is it? [[Special:Contributions/172.71.154.159|172.71.154.159]] 07:33, 17 December 2022 (UTC)

this three-quarters planet seems to be impossible to get out of without the "warp" engines if you get in the center: https://i.imgur.com/tMchAa1.png

i also got stuck in one planet by descending toward it very quickly https://i.imgur.com/9ilmtdK.png - in this state, descending and turning do nothing, but accelerating (pressing up) makes me slowly move downward and lets me turn very slowly

also, i went toward this planet (downward) at high speed and became knit cap somehow https://i.imgur.com/JlRFuy4.png --[[Special:Contributions/172.70.230.160|172.70.230.160]] 15:16, 17 December 2022 (UTC)

Instead of there being a wide "references" column with 4 sub-columns, I think it should be just a "references" column with what the reference is as the text, instead of it being a boolean. This also allows for more detail such as "What If 2, chapter 94: What if I made up a chapter name" or something like that [[Special:Contributions/172.71.22.22|172.71.22.22]] 15:46, 17 December 2022 (UTC)Bumpf

There is a planet at {x: 34704, y: -25501} with a space elevator attached to it. In that same planet, at {x: 31682, y: -34551}, there's a guy complaining about the framerate being "really bad out today"; the screen will stutter if you fly by him.

== What if 2 planet ==

It's got a dinosaur being offered a hamburger, a person firing a cannon (one cannonball nearly goes into orbit) and if you can get yourself struck by one of the cannonballs the ship transforms.

I'm not sure if the transformed ship is BETTER, but it is different.

==Explanation==
{{incomplete|Created by SPACE - Please change this comment when editing this page. 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 What If? 2 and previous xkcd comics. The flight mechanics are largely, if not entirely Newtonian, so the player vessel is capable of using the gravity of planets to alter its trajectory or even enter orbit.

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

This comic was released as a promotion for 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 following is an incomplete list of planets and other significant features:

Starting planet

Europa

B-612 (The Little Prince reference; also a reference to [[618: Asteroid]])

Dog park planet (What If? 2 reference)

What If? 2 scenario planet

Sun's core (What If? 2 reference)

The Sun

A cluster of black holes

Soup system (What If? 2 reference)

Earth without Japan (What If? 2 reference)

Just Japan (What If? 2 reference)

A blob labeled "Pigeons"

Starship Enterprise (Star Trek reference)

Dinosaur planet (Dinosaur Comics and Jurassic Park reference)

What If? 1 scenario planet

Cat blocking traffic flowing through portals

A tree larger than the planet it's growing on

Edge of the Universe (actually just a planet labeled "Edge of the Universe")

Milliways (Hitchhiker's Guide to the Galaxy reference)

2707: Astronomy Numbers

}}

==Explanation==
{{incomplete|Created by a CAT-LOVING LASER POINTER - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
Space is big{{citation needed}} and the things that are in space can also end up being very big themselves. As a result of this, most quantities in astronomy can vary by huge scales. For example, Earth has a mass 10^23 times more than the average human, and the Sun is 10^5 times more than that, which itself is 10^12 times less massive than the Milky Way. The same applies to speeds, distances, and time, which can often be measured in terms of light speed, light-years, and millions (or even billions) of years. Because of this, it's a truly unusual occurrence for anything in space to end up in the fairly narrow range of scales of mass, size, speed, or time that humans can easily grasp.

Ponytail, a scientist apparently researching something related to Earth's orbit, finds that on the next January 1, Earth will be approaching the sun at a velocity of 65 miles per hour—an extremely common and normal-sounding velocity to American ears, often used as a speed limit on highways in the US. Ponytail is clearly a little thrown-off by this, and remarks that she finds it "suspicious" when reasonably human-scaled numbers come up.

She then extends this paranoia to things that should be measured in regular numbers, such as the weight of cats. The vet (Megan) is seemingly used to this problem (perhaps she gets a lot of physicists), so she restates the 12-lb weight of Ponytail's cat in solar masses. Since using this unit yields an ''incredibly'' small number, 3*10^-30 (a three preceded by a decimal point and 29 zeroes), it evidently sounds more plausible to the astronomer. This weight is in fact about 13lb 2oz, slightly heavier than the cat, due to the less precise answer.

==Details on the numbers==
Although the Earth's orbital velocity around the Sun is far above any "normal" scales (around 30 kilometers per second or 108,000 kilometers per hour), Earth has a pretty circular orbit around the Sun so most of this speed ends up being tangential (sideways) rather than radial (towards or away from) the Sun, which is the value relevant for Ponytail's calculations. On January 1, Earth's radial velocity is close to its smallest value because we reach our closest point to the Sun in the first few days of January each year (in 2023, {{w|Perihelion|perihelion}} happens on January 4) so by January 1, it's nearly come to a standstill before it starts traveling away from the Sun again. On the other hand, by April 3, 2023, Earth will be receding from the Sun by almost 500 meters per second or 1800 kilometers per hour, a slightly less normal speed for the average person to encounter in everyday life.{{citation needed}}

65 miles per hour is approximately equal to 105 kilometers per hour, although the even more typical scientific value (in {{w|International System of Units|SI}} derived units) would be 29 meters per second. 3 × 10^−30 solar masses is approximately equal to 6 kilograms or 13 pounds (consistent with the 12 pounds, or slightly under 5.5 kilograms, of the original figure) and is normal, if perhaps slightly overweight, for a cat.

==Title text==
The title text suggests that laser pointers "love chasing" a new cat with a weight of 12 solar masses (an inversion of the typical cat behavior of [[729: Laser Pointer|chasing laser pointer dots]]).
All gravitational fields bend light towards their center, a 12 solar mass object would bend quite a lot. A Laser pointer pointed at such a cat would bend towards it or "chase" it. In fact, 12 solar masses, would have a Schwarzschild radius of around 36 kilometers, so a cat with that mass would very definitely be a black hole, drawing all light within 72 kilometers around it into its singularity.

Another interpretation of the title text is that Randall has (presumably) accidentally adopted a distant star instead, which astronomers usually take a liking to pointing laser pointers at during both star parties & normal parties they were unwisely invited to. Assuming Randall's 12-solar-mass cat goes through similar life cycles to a 12-solar-mass star, his cat will probably end up living a violent, short life of just a few million years before expanding into a red supercat and exploding as a feline supernova, which might explain why astronomers are so interested in pointing it out. Or maybe a {{w|Laser guide star}} for a telescope with adaptive optics is being referred to.

:[Ponytail is standing in front of a whiteboard writing on it with a pen, while Cueball looks over her shoulder from behind her. On the board is an almost circular ellipse with a cross that centers on a dot towards the left side of it. On the right side there is a small circle on the ellipse's line. There are several lines of wiggles representing unreadable text. To the left of the ellipse there are two lines near the top of and four near at the bottom of the ellipse. Ponytail is writing a fifth line below these almost under the ellipse. At the bottom to the left there is a rectangular frame with a line of text beneath it and at the bottom left corner there is a line forming a half closes rectangle around two dots.]
:Ponytail: …And we need to correct for our elliptical orbit. On January 1st, Earth will be approaching the sun at a rate of ...let's see...
:Ponytail: 65 miles per hour.
:Ponytail: Weird. Okay.
:Cueball: Weird?

:Ponytail: I get suspicious whenever I see a normal number in astronomy. We're not supposed to have those. Feels wrong.
:Ponytail: Scales should all be incomprehensible.

:[Megan in a lab-coat raised her hand palm up towards an animal carrier cage standing on her desk. The cage has a handle and five air holes are at the top. Behind two of them something black inside the cage can be seen. Ponytail is standing on the other side of the desk looking at Megan. Above the top of the panels frame there is a panel with a label:]
:Earlier, at the vet:
:Megan: Your cat weighs 12 lbs.
:Ponytail: Ridiculous, nothing weighs "12". You must mean 10-20? Or 1040?
:Megan: Fine. Your cat weighs 3x10-30 solar masses.
:Ponytail: Okay. Better.

This comic proposes Spacetime Soccer, an impossible sport. Not only would it be impossible for human players to travel through more than three spatial dimensions, it would also be very difficult to keep track of score and rules such as offsides. This comic was likely published in relation to the 2022 World Cup.

:Spacetime soccer got a lot of criticism for how many players fell into the gravity well, but what ultimately doomed it was the advanced mathematics required to figure out the offsides rule.

1818: Rayleigh Scattering

2022-11-29T01:53:41Z

172.70.131.52: /* Explanation */

{{comic
| number = 1818
| date = March 31, 2017
| title = Rayleigh Scattering
| image = rayleigh_scattering.png
| titletext = If you ask "why are leaves green?" the usual answer is "because they're full of chlorophyll, and chlorophyll is green," even though "why does chlorophyll scatter green light?" is a great question too.
}}

==Explanation==
This comic suggests it is better to explain things in an easy-to-understand and intuitive manner, even if such explanations may not capture all of the scientific detail involved. This is especially the case for children whose ability to grasp abstract physics has not yet fully developed. Giving the most complete and physically accurate explanation would make the concepts much more elaborate than necessary, and would cause major confusion in inexperienced listeners (see {{w|Ignotum_per_ignotius|Ignotum per Ignotius}}).

The principle is demonstrated by the explanation on {{w|Diffuse sky radiation|why the sky is blue}}. The commonly given explanation for this is, as the comic title says, {{w|Rayleigh scattering}}. However, in order to understand how Rayleigh scattering works to produce a blue color, one must go into {{w|quantum mechanics}} and deal with properties of molecules in air and their effects on different wavelengths of light. Even then, one will also need to know about the inner workings of human visual perception to realize why the color we perceive isn't the wavelength that's being most strongly scattered (see [[1145: Sky Color]]). The child is not likely to understand this kind of explanation.

On the other hand, a much simpler explanation, such as "because air is blue" — that is, air molecules reflect blue light, in the same way blue paint reflects blue light — also adequately explains the phenomenon, and is much more understandable to less physically inclined listeners. When [[Science Girl]] asks [[Blondie]] (possibly [[Miss Lenhart]]) why the sky is blue, [[Megan]] walks in and starts to explain in a very scientific way involving quantum mechanics. This is criticized by Blondie, who then convinces her that the simpler explanation is sufficient, as there is a quantum mechanical explanation for every color, there is no need to elaborate on the sky's color any more than any other object's color.

Megan implicitly accepts this, but then in the final panel, Science Girl asks another common question - how do planes fly? Megan starts again to give the traditional answer (airflow causing {{w|Lift_(force)|lift}}) but is interrupted by Blondie saying that it's because the wings of an airplane are full of small birds. While this might not be as ridiculous as it first seems (the child might later learn that the "tiny birds" are actually air molecules, and "flapping wings" are actually pressure differentials), it is certainly over-simplified to a staggering extent. Thus Megan and Blondie illustrate the two extremes of education philosophy: where one chooses to teach the complete truth with no regard for whether it's understandable, the other chooses to make up understandable explanations with no regard for whether it's true. Arguably, neither approach is in the student's best interest and a balance needs to be achieved.

When Science Girl reacts like she believes Blondie's last comment about the planes, she could almost have been called April Fool. Although this comic was released one day too early for that, this was also the only year between April 1st of 2011 and April 1st of 2018 where no such comic was released. See more about this in the [[#No April Fools' Day comic in 2017|trivia section]] below.

The title text refers to another common question as for why leaves are green. This is commonly explained by the fact that they are filled with {{w|chlorophyll}}, a chemical used by plants for photosynthesis. Randall points out that it would be an equally valid question to ask why chlorophyll is green. This poses an interesting contrast to the answer to the question about the color of the sky, since even physicists are usually satisfied with the general explanation for leaves and don't feel the need to jump into describing quantum phenomena that cause chlorophyll to reflect green light. Also, "Why does chlorophyll scatter green light" may be a great question because chlorophyll reflects, not scatters, light and this challenges Megan-types to coherently explain the difference before they go challenging little children with pedantry. Or because green light is less efficient during photosynthesis, and explaining that is similar to explaining Rayleigh Scattering.

[https://what-if.xkcd.com/141/ What-if 141] also mentions the simpler explanation to the original question: Sunbeam has this relevant text: "Normal light interacts with the atmosphere through Rayleigh scattering. You may have heard of Rayleigh scattering as the answer to 'why is the sky blue.' This is sort of true, but honestly, a better answer to this question might be 'because air is blue.' Sure, it appears blue for a bunch of physics reasons, but everything appears the color it is for a bunch of physics reasons." There is also a footnote in that comment with an additional example: "When you ask, 'Why is the {{w|Statue of Liberty|statue of liberty}} green?' the answer is something like, 'The outside of the statue is copper, so it used to be copper-colored. Over time, a layer of copper carbonate formed (through oxidation), and copper carbonate is green.' You don't say 'The statue is green because of frequency-specific absorption and scattering by surface molecules.' "

Randall himself has published [https://xkcd.com/thing-explainer/ Thing Explainer] which gives simplified descriptions of complex scientific and technological objects. Even in his book, some of the more advanced details have been simplified to a toy model (such as calling liquid oxygen "cold wet air" and a nuclear reactor "box of burning metal").

==Transcript==
:[Science Girl asks Blondie a question which she answers while lifting her arm towards Science Girl.]
:Science Girl: Why is the sky blue?
:Blondie: Because air is blue.

:[Megan walks in from behind Science Girl.]
:Megan: No, the sky is blue because of Rayleigh scattering–
:Blondie: Nah, it's because air is blue. Blue light bounces off it and hits our eyes. Same as why anything is any color.

:[Zoom in on Blondie's face.]
:Blondie: It's why far-off mountains look blue – because of all the blue air in the way.

:[Zoom out to Megan standing longer from Science Girl than Blondie who has thrown her arms out. Science Girl is facing directly out towards the reader.]
:Megan: There's a specific quantum mechanism by which–
:Blondie: Yeah but there's a physics mechanism for ''every'' color. You don't have to get all quantum right away.

:[Frameless panel with Science Girl looking up at Blondie who stands holding her hands on her sides. Megan speaks from off-panel.]
:Megan (off-panel): ...OK, I guess.
:Blondie: Any other questions?
:Science Girl: How do planes stay up?

:[Blondie holds a finger up in front of Science Girl while Megan now is the one to throw out her arms.]
:Megan: Well, the airflow–
:Blondie: Tiny birds in the wings. Thousands. Flapping hard.
:Science Girl: WOW!
:Megan: ''NO!''

==Trivia==
===No April Fools' Day comic in 2017===
*This comic was released the day before {{w|April Fools' day}}, but even though it could be said that Blondie makes up tales about physics that could cause her to call Science Girl an April Fool for believing her, this is definitely not one of [[Randall|Randall's]] [[:Category:April fools' comics|April fools' comics]].
**The reason for this trivia is that this year, 2017, was the first since 2011 that Randall did not release a comic on April 1st, and neither this Friday comic from the end of March, or the first comic in April, [[1819: Sweet 16]] from Monday April 3rd, could be said to have any relation to such a joke.
**As Randall took up the trend again in 2018 with [[1975: Right Click]], released on Sunday April 1st 2018, it showed that it was not because he just stopped with the April Fools' Day jokes.
***Randall might not have had either the mood or the energy needed to make a funny April Fools' Day comic at that time see more about that [[Sad comics|here]].

{{incomplete|Created by a PLATINUM CYLINDER FILLED WITH A KILOGRAM OF NEUTRINOS. Do NOT delete this tag too soon.}}

[[Randall]] is again promoting his new book, ''[https://xkcd.com/what-if-2/ What If? 2]'', and starts by explaining the kind of recipient who might appreciate it, basically anyone who is into science or anything in the universe... So basically anyone.

Then he also gives both direct and humorously indirect instructions of how to obtain the book for them, the latter method making a jocular (but not completely wrong) presumption that almost any text-input widget leads to some relevant search-engine result. Also the entire comic is a link to the ''What If? 2'' page on xkcd that's included in the comic. As always, clicking anywhere on the image will take you there (including actually clicking on the link).

He also suggests some other tongue-in-cheek gift ideas for several other subtypes of gift-receiver, most of which are, in keeping with the ''What If'' ethos, somewhat dangerous or impractical. A number directly reference things previously mentioned or depicted by xkcd.

{| class="wikitable"
|+
|-
! Interest !! Gift Idea !! Explanation
|-
| Engineering || The {{w|International Prototype of the Kilogram|platinum cylinder}} formerly used to define the kilogram || This is an object of historical relevance of which only six exist, making it a very expensive or illegal gift. With the {{w|2019 redefinition of the SI base units|redefinition of the SI base units}} in 2019, {{w|2019_redefinition_of_the_SI_base_units#Kilogram|the kilogram}} is now defined using only natural constants rather than a physical standard. It took some time before this last SI unit was redefined, 3 years prior to this comic's release. The old prototypes are no longer as important as they were when they were actually used to define the kilogram. But they are still historical artifacts with enormous value, even apart from the value of a kilogram of platinum (about $32 000 at time of writing).
|-
| Biology || The genomes of the scientists who headed the human genome project || The "International Human Genome Sequencing Consortium," as the {{w|Human Genome Project}} team was known, involved scientists from twenty institutions in six countries. In the US, it was initially led by DNA structure co-discoverer {{w|James Watson}} who was succeeded by {{w|Francis Collins}}. In the UK, the project was led by {{w|John Sulston}}. The teams from other countries' institutions were less prominent and performed substantially less work on the initial sequencing. James Watson's genome was sequenced in 2007. The genome of {{w|Craig Venter}}, the CEO of {{w|Celera Genomics}}, was used as the exemplar for Celera’s sequence. While the “race” between Celera and NIH was declared a tie by then-President Clinton, in actuality, Celera had some 85+% coverage while NIH was about 50%.
|-
| Physics || A beam of neutrinos delivered through the earth by the LHC || {{w|Neutrino}}s interact very weakly with other particles, to the point that they almost always pass straight through matter completely unaffected. This means that particle accelerators can send neutrinos to any other point on Earth by aiming the particle beam into the ground, and the neutrinos pass straight through the Earth. This point is referenced in the What-If article "{{what if|73|Lethal Neutrinos}}". The low interactivity of neutrinos would also mean that the recipient would be unable to perceive their gift, making this a poor present for anyone except the small proportion of physics aficionados who already have a neutrino detector on-hand.
|-
| Animals || Surprise wildlife encounter (gift-wrapped box with a bobcat inside) || This is a reference to [https://www.explainxkcd.com/wiki/index.php/Category:Bobcats xkcd's rich history of mailing boxed bobcats to people]. This gift would place the recipient in a perilous situation, and, although definitely a wildlife encounter, is not a good gift.{{Citation needed}}
|-
| Law || A vacation to that area of Idaho where you can commit crimes with impunity due to a court district boundary error || This refers to the "{{w|Zone of Death (Yellowstone)|Zone of Death}}", a 50-square-mile area of Yellowstone National Park that is in the physical boundaries of Idaho, but in the legal jurisdiction of Wyoming. Because a jury in the United States must be composed of residents of the same district ''and'' state in which the crime was committed, but no one lives in this small area of a National Park, anyone who committed a crime here could not (according to a legal theory not fully tested in the courts) receive a trial, and thus could not legally be punished for said crime in any circumstance. This is an interesting legal loophole, but going to this area does not provide any more value than hearing about it, and could scare your law-enthusiast friend.
|-
| Chemistry || A necklace of element samples whose symbols spell out the recipient's name (note: names like "Katherine" and "Brandon" may cause radiation accidents.) || Novelty necklaces are a common and innocuous gift. Using element symbols to replace letters in a name is a common gimmick (famously used in the title and credits of {{w|Breaking Bad}}). Using real samples of the given elements could be difficult, as elements can be expensive, highly reactive, or toxic. Reactivity and toxicity can be dealt with by containing them in well-sealed containers (which would also be necessary for elements that are liquid or gas at room temperature), but those elements that are radioactive could be dangerous, even if fully contained, and and some have short enough half-lives that a sample wouldn't persist long enough to be used as a gift. "Katherine" would be made from Potassium (highly reactive), Astatine (rare, '''radioactive''' and has a short half-life), Hydrogen (gaseous at room temperature, flammable), Erbium, Iodine (sublimes into a gas at room temperature), and Neon (gaseous at room temperature). "Brandon" would be made from Boron, Radium ('''radioactive'''), Neodymium, Oxygen (gaseous at room temperature), and Nitrogen (gaseous at room temperature). The problems with element samples could be partially alleviated by allowing compounds rather than pure elements, but the radioactivity would still be a problem, and neon does not form compounds and as such is always gaseous. Additionally, the letters J and Q do not appear in the periodic table symbols, while M does not appear on its own (only followed by six other characters, with "o" as the only vowel amongst them), so a name like John, Quinn, or Mike would be problematic.
|-
| Puzzles || Two goats and a new car || This is a reference to both the "{{w|Wolf, goat, and cabbage problem}}", involving a river crossing, and the "{{w|Monty Hall problem}}", in which a game show contestant has to choose between three doors, two of which conceal goats and one of which conceals a car, and wins whatever prize is revealed. (See [[2348: Boat Puzzle]] and [[1282: Monty Hall]], respectively, for other cartoons inspired by these problems.) This gift places the recipient within a puzzle which is typically discussed hypothetically rather than happening in real life. Although many people would consider a new car a ''great'' gift, those who would appreciate a gift of goats are less common.
|-
| Technology || Cybiko® wireless handheld computer for teens (2000) || This is a direct callback to [[2699: Feature Comparison|one of the previous week's comics]], which humourously suggested that this device is a better option than most of the current popular communication technologies. While an interesting example of the history of communication technology and coming from a time when experimentation was common and standards were few, it isn't very useful now, because it is no longer supported, has a communication range of 100 meters (sending text messages via radio) and one can only use it to communicate with users of the same device. However, technology enthusiasts could find it interesting as a collectors' item, so by all means it is one of the most plausible gift ideas on this list.
|-
| Space || Webb telescope personal photoshoot || The Webb telescope belongs to NASA, the ESA and the CSA, and is currently very far from Earth. It is designed to capture distant space objects in previously unseen detail. If the photoshoot implies photographing a nearby human, it is not designed to do this, even if the difficulties of sending a human about a million miles to its location could be overcome. On the other hand, if it means photographing the recipient on the earth's surface, Webb would have to point at the warm Earth and expose its optics to the Sun, permanently crippling the telescope ([https://webb.nasa.gov/content/about/faqs/faqLite.html Which is forbidden by NASA.]) and it would not have sufficient resolution to make out the subject in any case. These circumstances make it a highly impractical gift, to all intents and purposes to the point of impossibility.

On the other hand, a gift experience of being allowed to take your own snapshot of Webb in position, perhaps with a [https://www.dailymail.co.uk/sciencetech/article-10442913/James-Webb-Space-Telescope-seen-Earth-settles-orbit.html robotic telescope], might be an attractive gift to a space enthusiast! So might a chance to use the Webb telescope to take pictures of whatever celestial objects one chooses, as time on the Webb telescope is very carefully allocated.
|-
| Literature || Stephen King's writing desk (he's still using it so you'll have to fight him) || {{w|Stephen King}} is an author lucky enough to have legendary status while still alive. The desk of an author that has died would become an object of historic significance and would likely be either kept for exhibition or auctioned by their respective estate, but as Stephen King is still alive, he would probably object to his desk being subjected to the same.
|-
| Philosophy || Out-of-control trolley || This is another gift that places the recipient in the situations that they like discussing hypothetically. The {{w|trolley problem}} is a thought experiment in which one is asked to decide between allowing a trolley to kill five people or taking an action that causes it to kill one. Presenting someone with such a hypothetical problem may or may not be not a good gift, but [https://www.youtube.com/watch?v=1sl5KJ69qiA forcing them to live through it in real life] is a terrible gift. (See [[1455: Trolley Problem]] for another cartoon inspired by this problem.)
|-
| Psychology || A nice gift with a note saying you don't expect anything in return || This is perhaps the most viable option on this list. This kind of gift giving could induce the Benjamin Franklin effect, causing the gift giver to like the recipient more. It could also be used to manipulate the recipient by increasing pressure to reciprocate. This would cause them stress, making it a bad gift, but a psychologist would hopefully understand it to be a joke. A psychologist could also think about the psychology of gift-giving and reciprocation, perhaps to their enjoyment.
|-
| (Title text) Babies or literature but not both || Baby shoes || This is a reference to the six-word story {{w|For sale: baby shoes, never worn}}, often attributed to Ernest Hemingway. Someone involved with babies, such as expecting or new parents, would find baby shoes a valuable gift for their child. Someone interested in literature would see the reference to a famous work. But someone who understands the reference and also enjoys babies might be sad, since the story implies the seller was expecting a baby but something went tragically wrong.

A phone in portrait orientation shows an image. It is then rotated, showing the image smaller with bars in landscape view, then this repeats many times, shrinking it every time as labels tell us what sizes it reaches at certain levels.

Text:

"9 rotations: original image is smaller than a pixel."

"25 rotations: original image is smaller than an atom."

"101 rotations: original image is smaller than the Planck length, at which the concept of distance may break down."

Bottom caption: "Phone tip: don't rotate and screenshot an image too many times or it will become lost in the quantum foam of the universe."
