In addition to the many arguments that might occur through early morning or late night texting, it is also possible that a lot of arguments occur at those times because the facebook and texting activities at those hours interfere with normal healthy life activity and start with one's partner saying something like, "put the phone away and go to sleep".

599: Apocalypse

2017-12-11T16:31:21Z

141.101.104.161: /* Explanation */

{{comic
| number = 599
| date = June 19, 2009
| title = Apocalypse
| image = apocalypse.png
| titletext = I wonder if I still have time to go shoot a short film with Kevin Bacon.
}}

== Explanation ==
This comic begins with the beginning of the {{w|Apocalypse}}, hence the title. It is depicted, properly, with a very dystopian color picture with several yellow burning {{w|meteors}} striking down from the blood red sky, towards a black, red, orange and yellow ground. The way the panels are drawn below makes a transition from this dark image to a normal comic, with the first normal panel being superimposed on the dark image.

In this image [[Beret Guy]] shouts out '''The apocalypse!''' And then he continues to explain what this will mean: ''The skies burn, the seas turn to blood, and the dead walk the earth!''

All three sentences are attributed to the apocalypse, but it seems that the first one about the sky burning, actually comes from a translation of one of {{w|Nostradamus}} predictions, which has among other been used to "{{w|Nostradamus_in_popular_culture#September_11.2C_2001|predict 9/11}}". In {{w|Revelation 16}} from the bible about the {{w|Seven bowls}}, which are a set of seven plagues of God's wrath poured over the wicked towards the Apocalypse, the {{w|Seven_bowls#Second_Bowl|second bowl}} describes that ''{{w|Revelation_16#Structure|The Sea Turns to Blood}}''. The {{w|Universal resurrection|resurrection of the dead}} is from the biblical version of the Apocalypse, the {{w|Last Judgment}}.

After Beret Guy has announced this, he runs into [[Cueball]] who has heard part of this, but he is only interested in the last part and asks to check if he understood correctly that the dead will walk the earth. When this is confirmed Cueball becomes very busy.

He runs to his office and quickly writes a scientific math paper, then runs as fast as he can to the math department and get his colleagues to sign it. Then he runs to a cemetery where the dead are rising finds the one he searched for and asks the resurrected {{w|zombie}} if he is Erdős. When confirmed he ask him to sign the math paper.

{{w|Paul Erdős}} (26 March 1913 – 20 September 1996) was a Hungarian mathematician who (according to Wikipedia) published more papers than any other mathematician in history, working with hundreds of collaborators. His grave is in the Kozma Street Cemetery in Budapest.

There is an in-joke developed among mathematicians called the {{w|Erdős number}} (similar to a Bacon number for film actors, referenced in the title text, see below). By definition, Erdős has an Erdős number of 0. Everyone who has co-written a mathematical paper with Erdős has an Erdős number of 1. Everyone who collaborated with them (but not Erdős himself) is assigned an Erdős number of 2. In general, if ''k'' is the minimal Erdős number of all the people you've written papers with, your Erdős number is ''k'' + 1. The Erdős number is the length of the shortest "chain" from you to Erdős.

Thanks to collaboration between mathematicians and other researchers, many people in science and medical research now have Erdős numbers. Not everyone has an Erdős number, though; people without any chain linking them to Erdős have an undefined Erdős number. For example, most people who are not mathematicians or scientists do not have an Erdős number. Paul Erdős described people who had stopped doing mathematics as "dead."

By this trick Cueball thinks that he and his colleagues will now all have a an Erdős number of 1. The joke being that he would be using his last few hours in this life to write a math paper just to improve his and his friends Erdős number.

There is, however, many problems with his idea, even assuming the dead will walk the earth on that day. First of all having your name on a piece of paper with Erdős signature does nothing for your Erdős number. It needs to be a {{w|Scientific_literature#Scientific_article|scientifically valid paper}}, published in a {{w|peer reviewed}} {{w|scientific journal}}. And given that the apocalypse is happening, there seems no time, chance or reason to publish any more math papers.

Even if there were time, it would not count for much to have someone sign a math paper they haven't even read, let alone had anything to do with the actual writing and research. The same would be true for the other five mathematicians who signed it. But of course many papers have coauthors who did not do much more than work in the same department as the person who actually wrote the paper (a sad but true fact).

Furthermore even if it did count, they will not be able to take the paper with them into the afterlife, and thus since no one would have had time to read the paper, no one would know they had an Erdős number of 1. In the afterlife they could all say that they had such a number, but then again everyone else with such an interest could do the same, since no one could prove otherwise. Of course if you end up in the same part ({{w|Heaven}} or {{w|Hell}}) of the {{w|afterlife}} as Erdős he could confirm or deny the claim, but that would probably not help Cueball and his friends, since he could tell the truth about their paper.

That the whole comic is about the Erdős number, and not just Erdős signature, is made clear in the title text which refers to a similar (and less esoteric) meme called "{{w|Six Degrees of Kevin Bacon}}", or simply Bacon numbers. This time, the chain's center is actor {{w|Kevin Bacon}}, and the links are formed by two people appearing in the same movie. Unlike Erdős, Kevin Bacon is not dead, so those of you wishing to get a Bacon number of 1 still have a chance.

In the title text Cueball thus wonders if there is still time for him to run on an make a short film with Kevin Bacon, now he has used so much time on improving his Erdős number. Again, if the film hasn't been shown to the public it would not count for anything...

One of the mathematical scribbles appearing in panel 5 shows the square root of 163, which may be a reference to {{w|Ramanujan's constant}}.

[[403: Convincing Pickup Line]] has a parody of the Erdős collaboration graph.

Zombies are a [[:Category:Zombies|recurring theme]] in xkcd, particularly zombie scientists, which has also occurred both before with {{w|Richard Feynman}} in [[397: Unscientific]] and after with {{w|Marie Curie}} in [[896: Marie Curie]].

==Transcript==
:[The first panel is very large and shows a dark scene with one large meteor in front and four smaller in the background showering the darkened earth. They are all five black with yellow fire around them and a fire trail behind them, and all are flying from the top left corner and down towards right. The sky at the top is pitch black, but then the sky turns blood red under dark clouds. Two large mountain peaks, one almost pyramid shaped, are shown to the left and to the right there are two smaller peaks towards the distant horizon. The mountains and the ground around them are mainly black, but with red, orange and yellow streaks spread all over the black area beneath the mountain peaks, maybe indicating fire or lava, or reflections in water or blood. At the bottom right corner a normal white panel is superimposed on this apocalyptic image.]

:[The smaller panel at the bottom of the first is halfway over the first panel, haflway below, and only to the right of the middle of the first panel. Beret Guy is running towards left, with his arms raised in the air.]
:Beret Guy: The Apocalypse! The skies burn, the seas turn to blood, and the dead walk the earth!

:[From here a normal sequence of panles in three rows begin beneath the second panel. This leaves a gap between the apocalyptic panel and the third row of panel, on the left side where the 2nd panel did not reach over. In this panel Beret Guy (coming from the right) finds Cueball.]
:Cueball: The dead what?
:Beret Guy: Walk the earth!

:[Cueball running right in a thin panel.]
:Cueball: I have to go.

The first who signs with a pen is Blondie, then in line follows Megan, a Cueball-like guy, Ponytail and another Cueball-like guy who stand with one hand to his chin looking right, away from the other.]
:Blondie: At last!

:Rising dead (off-panel): ''Hurrghhh''

:[Cueball, still going right, arrives at a grave, pen in hand and the other hand almost outside the panel, but with a corner of the paper just visible. The grave has a large gravestone to the right and in front of it there is a Cueball-like guy rising up from the ground using his arms to push up on the base of the stone and the small pile of earth towards Cueball. The guy looks very worn, with dirt on his head and scratches on his cheek.]

:[Cueball bends a little down and offers pend and paper to the raised dead man who looks up at him when he is addressed-]
:Cueball: Paul Erdős?
:Erdős: Yes?
:Cueball: We need you to sign this.

*This version of [[Blondie]] seems to be employed at a mathematical department on a university. It could thus also be [[Miss Lenhart]], but there is no proof that she is a teacher...

977: Map Projections

2015-05-27T15:06:59Z

141.101.104.161: changed linked to http://en.wikipedia.org/wiki/Winkel_tripel_projection

{{comic
| number = 977
| date = November 14, 2011
| title = Map Projections
| image = map_projections.png
| titletext = What's that? You think I don't like the Peters map because I'm uncomfortable with having my cultural assumptions challenged? Are you sure you're not... ::puts on sunglasses:: ...projecting?
}}

==Explanation==
{{w|Map projection}}, or how to represent the spherical Earth surface onto a flat support (paper, screen...) to have a usable map, is a long-time issue with very practical aspects (navigation, geographical shapes and masses visualization, etc.) as well as very scientific/mathematical ones, involving geometry or even abstract algebra among other things. There is no universal solution to this problem: Any 2D map projection will always distort in a way the spherical reality. Many projections have been proposed in various contexts, each intending to minimize distortions for specific uses (for nautical navigation, for aerial navigation, for landmass size comparisons, etc.) but having drawbacks from other points of view. Some of them are more frequently used than others in mass media and therefore more well-known than others, some are purely historical and now deprecated, some are very obscure, etc.

[[Randall]] suggests here the idea that someone's "favorite" map projection can reveal aspects of their personality, then goes through a series of them to show what they can mean:

;Mercator
[[File:MercatorProjection.jpg|frame|The Mercator projection]]
:The {{w|Mercator projection}} was introduced by Flemish cartographer Gerardus Mercator in 1569. The main purpose of this map is that at any point the vertical and horizontal scales are the same, so locally i.e. considering only a small part of the map, geographical features (shapes, angles) are well represented, which helps a lot in recognizing them on-the-field, or for local navigation in that small part only. For this reason, that projection (or a close variant) is used in several online mapping services, such as Google Maps, which means that it is frequently encountered by the general public. No angle distortion also means that a straight line on the map corresponds to a course of constant bearing (direction), which was very useful for nautical navigation in the past (and thus made that projection very well-known).

:However, from a global point of view, this projection is radically incorrect in how it shows the size of landmasses (for instance Antarctica or Greenland seem gigantic), and furthermore, it always excludes a small region around each pole (otherwise the map would be of infinite height), so it doesn't provide a complete solution for the problem of map projection. The comic implies that people who like that projection aren't very interested with map issues, and typically use what they are offered without thinking much about it.

{{clear}}

;Van der Grinten
[[File:VanDerGrintenProjection.jpg|frame|The Van der Grinten projection]]
:The {{w|Van der Grinten projection}} is not much better than the Mercator. It was adopted by {{w|National Geographic}} in 1922 and was used until they updated to the Robinson projection in 1988.

:The Van der Grinten projection is circular as opposed to the Mercator projection. Circles look happier than squares, leading to the conclusion that people who like the projection are optimistic.

{{clear}}

;Robinson
[[File:RobinsonProjection.jpg|frame|The Robinson projection]]
:The {{w|Robinson projection}} was developed by {{w|Arthur H. Robinson}} as a map that was supposed to look nice and is often used for classroom maps. National Geographic switched to this projection in 1988, and used it for ten years, switching to the Winkel-Tripel in 1998.

:{{w|The Beatles}} was a rock band that enjoyed great commercial success in the 1960s. The Beatles, coffee, and running shoes suggest an ordinary, easygoing lifestyle paralleled by the projection.

{{clear}}

;Dymaxion
[[File:DymaxionProjection.jpg|frame|The Dymaxion projection]]
:Also called the Fuller Map, the {{w|Dymaxion Map}} takes a sphere and projects it onto an icosahedron, that is a polyhedron with 20 triangular faces. It is far easier to unwrap an icosahedron than it is to unwrap a sphere into a 2D object and has very little skewing of the poles.

:Randall associates the projection to geek subculture and niche markets:
:*{{w|Isaac Asimov}} was an American science-fiction writer, that (as well as publishing many textbooks) is considered the father of the modern concept of robots. He invented the {{w|Three Laws of Robotics}}. He also worked on more than 500 books throughout his career.
:*{{w|XML}} is the eXtensible Markup Language. It is used to represent data in a format that machines can read and understand, as well as being human-readable. In practice, XML is cumbersome to read.
:*{{w|Vibram FiveFingers|Toed-Shoes}} are a [[1065: Shoes|favorite]] of Randall's to pick on. In society they are seen as a {{w|geek}} clothing item.
:*Brought to the world by {{w|Dean Kamen}}, the {{w|Segway PT}} was supposed to be a device that changed the way cities were built. In reality, most principalities have put in place rules specifically against Segways, making them a frustration to own and use within the law (in some states in Australia, it is illegal to use them on public footpaths or roads). Also, the former owner of {{w|Segway Inc.}}, the late {{w|Jimi Heselden}}, accidentally rode his Segway off a cliff in 2010.
:*{{w|Virtual reality|3D goggles}} are a very niche market only pursued by enthusiasts. In the 1990s the promise of virtual realities was very tantalizing; many companies attempted to perfect it, but fell short of the mark. Also, the phrase "The grass is always greener on the other side of the fence" is relevant.
:*{{w|Dvorak Simplified Keyboard|Dvorak}} is an alternate keyboard layout to QWERTY. According to legend, QWERTY was invented to help keep manual typewriters from jamming (by placing the most used keys far from each other) but Dr. {{w|August Dvorak}} performed many studies and found the mathematically optimal keyboard layout to reduce finger travel for right handed typists. While some claim Dvorak is technically better than QWERTY, QWERTY had become the standard. All the keyboards were laid out in QWERTY format, and retraining the brain after becoming a touch typist is extremely difficult.

{{clear}}

;Winkel-Tripel
[[File:Winkel-TripelProjection.jpg|frame|The Winkel Tripel projection]]
:Proposed by Oswald Winkel in 1921, this {{w|Winkel tripel projection}} tried to reduce a set of three (German: Tripel) main problems with map projections: area, direction, and distance. The {{w|Kavrayskiy VII projection|Kavrayskiy projection}} is very similar to the Winkel Tripel and was used by the USSR, but very few in the Western world know of it.

:The comic links this projection to {{w|hipster}} subculture. The hipster stereotype is to avoid conforming to mainstream fashions. "Post-" refers to a variety of musical genres such as {{w|post-punk}}, {{w|post-grunge}}, {{w|post-minimalism}}, etc. that branch off of other genres.

{{clear}}

;Goode Homolosine
[[File:GoodeHomolosineProjection.jpg|frame|The Goode Homolosine projection]]
:The {{w|Goode homolosine projection}} takes a different approach to skewing a sphere into a roughly circular surface. An orange peel can be taken from an orange and flattened with fair success; this is roughly the procedure that {{w|John Paule Goode}} followed in creating this projection. Randall is suggesting that people who like this map also prefer relatively easy solutions to other things in life, despite those solutions having nuanced problems that are more difficult to address.

:Common people make arguments that if normal people would run the United States, then the US wouldn't be in the trouble it is. This is from the belief that career politicians are simply out to make money and will only act in the interest of their constituency when their continued easy life is threatened (usually around election time).

:Airline food is another, much maligned, problem. How do you store enough food to feed people on long airplane trips? The common solution is to use some kind of sub-standard microwaveable dinner. Randall is saying that the people in favor of the Goode Homolosine wonder why the airlines don't simply order meals from the restaurants in the airport, store that food, and serve it, rather than using frozen and microwaved food.

:Older cars burned oil like mad fiends, and oil back then would become corrosive to the innards of an engine, so oil had to be changed often. But, with the introduction of synthetic motor oil and better designed engines, new cars only need their oil changed about every 10,000 to 15,000 miles. A common conspiracy theory is that modern automobile oil manufacturers still recommend that car owners change their oil every 3,000-5,000 miles to "drum" up more business, even though that frequency is unnecessary.

:All of these references suggest that people who like the Goode Homolosine projection are fans of easy solutions to problems. However, the solutions would not necessarily work in practice. For instance, the restaurants might have trouble making enough food for the whole plane, and it could get cold before being served. Also, the air conditions [http://www.nbcnews.com/health/one-reason-airline-food-so-bad-your-own-tastebuds-6C10823522 aboard planes] can affect taste, so airlines say they optimize for this. And there is no such thing as a "normal" person, and if there were, he/she would have virtually no chance at actually getting into government office.

{{clear}}

;Hobo-Dyer
[[File:Hobo-DyerProjection.jpg|frame|The Hobo-Dyer projection]]
:The {{w|Hobo–Dyer projection}} was commissioned by Bob Abramms and Howard Bronstein and was drafted by Mick Dyer in 2002. It is a modified {{w|Behrmann projection}}. The goal was to be a more visually pleasing version of the Gall-Peters.

:As is discussed in the Gall-Peters explanation, the Gall-Peters was developed to be equal area, so that economically disadvantaged areas can at least take comfort in the fact that their country is represented correctly by area on maps.

:Randall associates the Hobo-Dyer projection to "crunchy granola" — a stereotype associated with vegetarianism, environmental activism, anti-war activism, liberal political leanings, and some traces of {{w|hippie}} culture.

:With the new general acceptance of homosexual, bisexual, and transgender persons, some have begun to invent gender-neutral pronouns so that when referring to a person whose gender is not known they cannot be offended by being referred to by the wrong pronouns. In {{w|Middle English}} 'they' and 'their' were accepted gender-less pronouns that could replace 'he', 'she' as well as be used to represent a crowd, but this usage is considered by some to be grammatically incorrect because of the plural/singular debate ([http://www.merriam-webster.com/video/0033-hisher.htm stupid Victorian Grammarians!]). None of the {{w|gender-neutral pronoun#Invented_pronouns|many attempts at popularizing gender-neutral pronouns}} have achieved any degree of success in the mainstream.

:Randall seems to associate the Hobo-Dyer projection with the Social Justice movements on social media sites such as Tumblr.

{{clear}}

;Plate Carrée
[[File:PlateCarreeProjection.jpg|frame|The Plate Carrée projection]]
:Also known as the {{w|Equirectangular projection}} has been in use since, apparently, 100 AD. The benefit of this projection is that latitude and longitude can be used as x,y coordinates. This makes it especially easy for computers to graph data on top of it.

:According to the comic, the projection appeals to people who find much beauty in simplicity.

{{clear}}

;A Globe!
[[File:GlobeProjection.jpg|frame|The Globe "projection"]]
:In any good discussion there has to be at least one smart-ass. This is a comic about map projections, that is, the science of taking a sphere and flattening it into 2 dimensions. The smart-ass believes that we shouldn't even try: a sphere is, tautologically, the perfect representation of a sphere.

:To quote ''{{w|The Princess Bride}}'': "Yes, you're very smart. Shut up."

{{clear}}

;Waterman Butterfly
[[File:WatermanButterflyProjection.jpg|frame|The Waterman Butterfly projection]]
:Similar to the Dymaxion, the {{w|Waterman butterfly projection}} turns a sphere into an octahedron, and then unfolds the net of the octahedron, which was devised by mathematician {{w|Waterman polyhedron|Steve Waterman}} based upon the work of {{w|Bernard J.S. Cahill}}

:Bernard Cahill published a [http://www.genekeyes.com/B.J.S._CAHILL_RESOURCE.html butterfly map] in 1909. Steve Waterman probably has the only extant "ready to go" map following the same general principles, though Gene Keys may not be far behind. Waterman has a poem with graphics in a similar vein to this xkcd comic that is worth reading.[http://watermanpolyhedron.com/worldmap.html]

:[http://www.progonos.com/furuti/MapProj/Normal/ProjPoly/projPoly2.html Polyhedral projections] like Cahill, Dymaxion or Waterman typically offer better accuracy of size, shape and area than flat projections, at the expense of compass directionality, connectedness, and other complications.

:The joke is that the person responding deeply understands map projections; anyone who knows of this projection is a person that Randall would like to get to know.

{{clear}}

;Peirce Quincuncial
[[File:PeirceQuincuncialProjection.jpg|frame|The Peirce Quincuncial projection]]
:The {{w|Pierce quincuncial projection}} was devised by {{w|Charles Sanders Peirce}} in 1879 and uses {{w|complex analysis}} to make a {{w|conformal mapping}} of the Earth, that conforms except for four points which would make up the south pole.

:{{w|Inception}} was a 2010 movie about {{w|meta}} {{w|lucid dream}}ing. It has a complex story that is difficult to follow and leaves the viewer with many questions at the end, and almost needs to be watched multiple times to be understood.

:The human brain is not well developed to deal with oddly obvious things. One example is that everyone has a skeleton, but everyone is surprised to see a part of their body represented by an X-Ray. Another is the fascinating complexity of the human hand, a machine which is amazingly complex, driven by a complex interplay of electrical and chemical signals; yet is the size of the hand and so useful.

{{clear}}

;Gall-Peters
[[File:Gall-PetersProjection.jpg|frame|The Gall-Peters projection]]
:The {{w|Gall-Peters projection}} is mired in controversy, surprising for a map. {{w|James Gall}} a 19th century clergyman presented this projection in 1855 before the {{w|British Association for the Advancement of Science}}. In 1967, the filmmaker {{w|Arno Peters}} created the same projection and presented it to the world as a "new invention" that put poorer, less powerful countries into their rightful proportions (as opposed to the Mercator). Peters played the marketing game and got quite a few followers of his map by saying it had "absolute angle conformality," "no extreme distortions of form," and was "totally distance-factual" in an age when society was very concerned about social justice. All of these claims were in fact false. The polar regions are horribly distorted, and south of the Mediterranean Sea is "taller" than it should be.

:Anyone who loves such a politically charged map that has become popular by way of marketing stunts, Randall would rather not have anything to do with.

{{clear}}

The title text makes a joke that goes to the familiar meme from ''{{w|CSI: Miami}}'', in which the star, David Caruso starts a sentence, then [[:Category:Puts on sunglasses|puts on his sunglasses]] and ends the sentence with a corny pun. In this case, the pun is on {{w|map projection}} and {{w|projection (psychology)|projection}} in Psychology. Psychologic projection is an immature defense mechanism wherein a person who is uncomfortable with their own thoughts and/or actions assumes that another also shares this thought or action and blames that person for thinking/behaving that way, removing some of the negative feelings they have towards themselves. The Sunglasses internet meme has been mentioned previously by xkcd in comics [[626]], [[524]] and possibly others.

Talk:1522: Astronomy

2015-05-08T08:07:53Z

141.101.104.161:

For a telescope you can be far away, for a magnifying glass or microscope you need a ladder to be nearer to the stars. Microscopes are for biology, telescopes for astronomy.
They have got a similar purpose, but look and are applied differently. Sebastian --[[Special:Contributions/108.162.254.122|108.162.254.122]] 07:09, 8 May 2015 (UTC)
Seemed like another example of Beret guy contradicting how things work, like how he blows into the power cord and inflated a computer, or how he plugged a cord into a power outlet labeled "COFFEE" and coffee came out. [[Special:Contributions/108.162.238.168|108.162.238.168]] 07:19, 8 May 2015 (UTC)
:Yes obviously this approach works for Berret Guy because this is what he does. Explanation lacks this fact. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 07:44, 8 May 2015 (UTC)
:Soup, wasn't it? But yes, for some reason he can actually use a stepladder to get a closer look (and a better one, thanks t the magnifying glass) on the "curtain of the night", which for him ''is'' actually within reach. As if it is just like a stage back-cloth with some form of star-effect (holes and backlight or sewn-in LEDs) as far as he is concerned.
:But what I was actually coming here to say was regarding Astrobiology being a portmanteu (as currently in the explanation). I'm not sure I'd call it that. It's really a perfectly normal compound description of a study area, like many others in science, used to clarify what ''subset'' of biology it is (e.g. paleobiology being the biology of historic organisms, more or less, coming roughly from the greek for "old life study"). Although it does rather hint at it's "the biology of stars themselves", as opposed to the perhaps more accurate exobiology ("outside life study") when it comes to off-Earth life not in (or being) actual stars; or xenobiology ("strange life study"), although that does tend to include oddments of obscure Earth biology and artificial life as well and really doesn't mean the study of extra-terrestrial organisms...

A minor comment on the incorrect use of the word ''portmanteau'' in the explanation so far: it is defined as [http://www.thefreedictionary.com/portmanteau a word formed by merging the sounds and meanings of two different words], [[wikipedia:portmanteau]]; however, [http://dictionary.reference.com/browse/astro- astro-] is a combining form of the the greek word ''aster'' meaning ''star'', used to form compound words, such as ''astro-bio-logy'' (aster-bios-logos: star-life-word). See [[1485]] for an example of the correct use of ''portmanteau''. (someone beat me to it while i was editing this ;-))
[[Special:Contributions/141.101.104.161|141.101.104.161]] 08:07, 8 May 2015 (UTC)

You could view the comic as a theatrical production, Megan's telescope as a prop, and Beret guy is just inspecting the backdrop. The ladder is for comic and aesthetic effect

Cueball assumes it's a question common to all of internet-accessed humans, making it seem like a beautiful thing. In the end, it turns out those are actually helpless birds asking this question worldwide, not people. I'd advise you add a [http://en.wikipedia.org/wiki/On_the_Internet,_nobody_knows_you%27re_a_dog On the internet, nobody knows you're a dog] reference.
The ice/catcher in the rye connection is far fetched. Judging by the Clark/Superman comparison, Randall suggests that birds turn into the rain as part of the water/ice phases and not hide from it. Because Clark doesn't go when Superman arrives, he turns into Superman. [[User:Dulcis|Dulcis]] ([[User talk:Dulcis|talk]]) 08:01, 15 October 2014 (UTC)

:Actually, I think Clark will end up on bottom of the phone booth.

So for the transcript, I'm thinking until the full text in every screen snippet is transcribed and each source result website is identified, it will be technically incomplete - any commentary on this (?) -- [[User:Brettpeirce|Brettpeirce]] ([[User talk:Brettpeirce|talk]]) 12:43, 15 October 2014 (UTC)

: While maybe technically incomplete, surely we have to be sensible, and take the decision to omit text which isn't really relevant to the comic.

:Alright, well, I did for the first 20 screen snippets what I think would be good to do for the remaining ones (find the source site and page, then quote what seems to be the pertinent question and answer text that is visible in the snippet, disregarding usernames, dates, categories and similar meta data).

DELETE!!") -- [[User:Brettpeirce|Brettpeirce]] ([[User talk:Brettpeirce|talk]]) 14:29, 15 October 2014 (UTC)

I also kind of think that the transcript should have the links to the source sites (since they are screen snippets), while the explanation should have the translations for any non-english text and any needed explanation for differences in cultural context. Regardless, having links to the source sites seems unnecessary to have in BOTH places, but they're links, so... they don't take up any more room, I suppose... -- [[User:Brettpeirce|Brettpeirce]] ([[User talk:Brettpeirce|talk]]) 14:40, 15 October 2014 (UTC)

: Great job on the transcript. Personally I like the link to original source as you've done, though perhaps other would disagree. I'm tempted to say it should also be in the explanation, as that is where I assume others would expect that type of information to be. I'm actually quite impressed at what a quality page this is after only a matter of hours, especially given that it isn't the simplest comic. Images, tables, translations, original sources...

The non-capitalization of the German nouns in the given example is perhaps caused by the input device.
