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

*the use unqualified of the words "still many people" is exactly the kind of weasely nonsense that this comic is designed to refute. there are "still many people" who claim the earth is flat, that they have been abducted by aliens, or that the MMR jab made their children autistic. those people are deluded or insincere. the difference with deniers of climate change is that there are in their ranks scientists who are clear-sighted but who have decided that funding at any price is better than none. this site should be better than that. --[[Special:Contributions/141.101.98.84|141.101.98.84]]

Is nobody else having a problem seeing the comic? Both here and on XKCD I get an "Image not found" icon, a blue question mark. I thought maybe this was an interactive comic that doesn't work on my iPad (like that garden thing, though that did nothing on my computer either). If I tap it on XKCD nothing happens, here it leads to the picture's Wiki page - also with the question mark - which says it's a PNG, which I know this iPad can show. It's 11pm EST, maybe night maintenance on XKCD?

When I force the issue, by going directly to the image URL listed on XKCD, the first time Safari crashed rather than load the image (but it crashes on a regular basis, so that didn't deter me), the second time it crashed, the third time it actually loaded, and I was able to see it. After seeing mentions here of spelling errors (though I have to disagree on "Pokemon", generally only people connected to the show bother with the accent.

Okay, now that I've managed to SEE the damn thing, I have a question. There's no mention of why this is using "BCE" and "CE" instead of the standard "BC" and "AD", never mind what these stand for (thinking and thinking about it, my guess is "Before Christ Era" and "Christ Era"). This is the kind of thing that should be mentioned on ExplainXKCD, LOL! Fun fact: when I searched this page for "BCE", to confirm it wasn't explained, I got "Over 100 matches". :) Anyway, I figure maybe those are currently accepted scientific terminology, especially since "AD" is Latin, unlike "BC", but the average person still uses BC and AD. In fact, I think this is the first time I've ever seen BCE and CE (unless it's been on XKCD before and I just dismissed it as a typo or something. This time there are WAY too many for it to be a mistake every time, including here in the explanation!) - NiceGuy1[[Special:Contributions/108.162.218.239|108.162.218.239]] 21:20, 14 September 2016 (UTC) I finally signed up!

:It's "Before Common Era" and "Common Era", an alternative to BC/AD.

:::I assume nothing. My statements are completely accurate. I OBSERVE it is the standard, the only standard anybody (else) seems to use. BC/AD is the "standard" because it is standard practice to use it. For good reason, since I would estimate just about everybody knows what it means, while I am sure I am in the majority in having never heard BCE/CE. It is also not "my" way, I made no choice here, it is the established convention, it is the way accepted and adopted by society. While I would normally be more inclined towards terminology devoid of religion (as seems to be the point here, now that someone kindly clarified these acronyms for me), I feel this would be a losing fight, one it would be foolish to attempt, the classic terminology is too ingrained in society.

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

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

I understand the concept behind this comic, but why doesn't the graph include atmospheric CO2, sulfur aerosols, and solar 10.7cm radio flux for comparison? Also, for the person who suggested we look at previous interglacial periods, I may be wrong, but I believe a lot of that data comes from ice cores, that would make it hard to look at time periods before the present ice sheets existed. IIRC, there were periods not too long ago (geologically speaking) where Antarctica was covered in lakes, tundra, and sparse forests instead of ice sheets.[[Special:Contributions/172.68.65.127|172.68.65.127]] 05:08, 16 September 2016 (UTC)

The jump of 0.5 degrees from 2000 to 2016 has been shown to be false. It exists because "scientists" went back and changed (or "seasonally adjusted") their data to fit their preconceived conclusions. Just look at Al Gore's 'Inconvenient [Non]Truth', pretty much every doomsday scenario has not occurred.

Oxygen 25 - 32%
Carbon dioxide 0.1 - 0.15%
Average Temperature 14 - 18 °C

and there should be no polar ice caps

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

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

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

Very interesting and important work.

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

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

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

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

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

It says that in order to '''possibly''' reach the "optimistic" +2° scenario (Randall's 2nd line, not the 1st one), we would need to cut anthropogenic CO2 to about 1/10th our current level, which is ridiculously unlikely to happen. The other graphs you posted are just hypothetical extrapolations about energy production that, even if they're trustworthy (which I doubt) don't reference any climate scenarios at all, much less ones better than the timeline.

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

See more here.</blockquote>

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

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

602: Overstimulated

2020-02-18T18:13:07Z

172.68.54.28: /* Explanation */

{{comic
| number = 602
| date = June 26, 2009

| titletext = My favorite thing to do at parties is to talk judgmentally about people who aren't there.
}}

==Explanation==

After being cooped up working on papers, [[Cueball]] goes to a party, only to find himself tuning out the gossip of his friends in order to work on math problems in his head. He writes down the prime numbers on cards, and then stretches them out such that the area of the card is the same (say, 1), but one of the sides has been elongated to a length equal to the number on the card. This reduces the length on the other dimension to the reciprocal of the number on the card (i.e. 1/''n'', with ''n'' being the number on the card), according to the area formula for rectangles.

Stacking these reciprocals all up will eventually diverge, meaning the sum will be infinite without ever leveling off. This is referred to as the {{w|divergence of the sum of the reciprocals of the primes}}, and was proven by {{w|Euler}} in 1737.

[http://aq.server8.org/ The Cambridge Aspergers Test] includes questions on preferences for, and ability to cope with, social situations. It also asks the person taking the test if they have an affinity for numbers and see patterns in every day objects. Cueball could possibly score high on the Asperger's scale — or he could just be introverted, or find math more interesting than criticizing others which is generally considered in science circles a dull thing to do considering the vast variety of other topics and activities available. {{w|Introversion}} is an idea from psychology. Thinking about things on one's own is often relaxing for an introvert, while hanging out with other people is not. Hence the irony of the comment in the last panel. Cueball's friends fail to realize that hanging out with them is actually more stressful for him than doing math - especially when people are doing nothing but talking negatively about those not present.

The title text mentions people that talk negatively about people that aren't there. A much later comic; [[1176: Those Not Present]], is about just that.

1694: Phishing License

2018-06-06T15:00:18Z

172.68.54.28: /* Explanation */

{{comic
| number = 1694
| date = June 15, 2016
| title = Phishing License
| image = phishing_license.png
| titletext = Later, walking out of jail after posting $10,000 bail: "Wait, this isn't the street the county jail is on."
}}

==Explanation==
{{w|Phishing}} is a scam where a criminal sends emails or other messages (often large numbers of them) pretending to be from a trusted institution in order to obtain passwords, credit card numbers, or other personal details of victims. The term is a neologism, playing on the term "fishing", because the process is likened to dangling bait and waiting for someone to bite. Phishing is illegal under both traditional fraud laws and modern {{w|cybercrime}} laws.

A {{w|fishing license}} is a government-issued permit allowing the catching of fish in controlled waters.

[[Cueball]] saw the sign offering phishing licenses, and was immediately arrested by the receptionist [[Ponytail]] upon applying for one. There is no need for a license for a crime like fraud, so it is dubious an authority would issue them, hence why Cueball should have been more suspicious of the offer. The joke is that the process of offering "phishing licenses" is analogous to the process of phishing itself: they pretend to be a legitimate business and display a sign with a false offer, hoping someone will be fooled into interacting with them. While the ideal phishing attempt is indistinguishable from the real thing, that's generally impossible to attain and there are always some ways to identify it as a scam. But still some people fall into the trap, partly because they don't know what to be on the alert for, and partly because the attempt is often directed at so many people at once that statistically there will be some that will fall for it. Still as Cueball himself states, he should have known it was a scam.

The title text reveals that Cueball's arrest was itself a scam, not an actual police {{W|Sting operation|sting}}, adding even more "phishing" to the phishing phor photential phishers. He has been put in jail, but is allowed to walk out after paying a {{w|bail}} of $10,000, only to find that when he gets back out on the street, it is not the street on which the county jail has its address. So Ponytail is actually not trying to capture people who would be interested in scamming people, she is trying to scam those people instead; although this is illegal, it may be rather clever as such people might not be likely to go to the police. Another joke in the title text is that a way to recognize phishing attempts is to look at the address of the website (or in his false prison sentence, the street address instead of the web address).

==Transcript==
:[A sign has an arrow below the text that points toward a sales window in a wall (with glass in front and small semicircular opening at the bottom for transferring money and goods). On each side of the window there are two pieces of paper with illegible text, and there is also one below the window that seems to have some kind of stamp or seal, still illegible). In front of the window [[Cueball]] is addressing [[Ponytail]] who sits behind the window.]
:Sign: <big>Phishing license</big> apply here
:Cueball: Hi, I’d like to apply for a—
:Ponytail: You’re under arrest.

1928: Seven Years

2018-04-16T23:07:24Z

172.68.54.28: /* Transcript */

{{comic
| number = 1928
| date = December 13, 2017
| title = Seven Years
| image = seven_years.png
| titletext = [hair in face] "SEVVVENNN YEEEARRRSSS"
}}

==Explanation==

[[Randall]]'s then girlfriend, now wife, was diagnosed with cancer in late 2010, a matter he has discussed in the comic [[:Category:Cancer|multiple times before]]. Here, motivated by the seven-year period between the American solar eclipses of {{w|Solar eclipse of August 21, 2017|2017}} and {{w|Solar eclipse of April 8, 2024|2024}}, we see them reminiscing the seven years prior to the first eclipse, leaving an open question to what the next seven years will bring.

This comic is a continuation of [[1141: Two Years]], which is shown as the first eight panels, slightly grayed out.

It was released as a response to another cancer diagnosis, this is explained in the [[Design_of_xkcd.com#Header_text|Header text]], which, for [[Design of xkcd.com#Unique header text|this comic only]], has replaced the standard ''xkcd updates every Monday, Wednesday, and Friday.'' The header for this comic, with the active link included, is:
Becky Beaton, sister of fellow cartoonist Kate Beaton, has also been diagnosed with cancer. You can support her treatment [https://www.youcaring.com/beckybeaton-1008390 here].
{{w|Kate Beaton}} is the creator of the web comic [http://www.harkavagrant.com/ Hark! A Vagrant]. Although this comic is not one on Randall's list of [[Design_of_xkcd.com#Comics_I_enjoy|Comics I enjoy]], he is clearly much influenced by another cancer diagnosis among someone in his own creative field.

[[Image:seven years key.png|right]]

Explanations of the individual panels:

*Panels 1–8: See [[1141: Two Years]], where there are also three more panels, not included here, with the punch line for that comic.
*Panel 9: Randall (drawn as [[Cueball]]) and Randall's wife (with her hair noticeably longer than it was at the end of [[1141: Two Years]], so she looks like [[Megan]]), are walking through a forest with very tall trees (maybe {{w|Sequoiadendron giganteum|giant redwood}}). The perspective is from a distant vantage point, and themes of extreme longevity are mixed with new growth: The old trees are so tall they grow out of the frame, yet saplings are clearly growing as well.
*Panel 10: Randall's wife is sitting down, not in the forest anymore. She is concerned because she has pain in her toe and worries that this is an early sign of her cancer spreading again. Randall points out the simpler explanation- that she stubbed her toe the previous day, and the pain is likely a result of that. This panel shows the paranoia that comes from cancer remission, as earlier explained in [[931: Lanes]].
*Panel 11: Randall and his wife are going spelunking (aka {{w|caving}}). Their guide, [[Hairy]], is gesturing deeper into the cave while Randall and his wife are climbing down.
*Panel 12: Randall's wife stands on a rock above an alligator in a swamp, photographing the alligator. Randall, on a balcony behind safety railings, observes that medical predictions about the odds of someone surviving cancer generally assume that the cancer patient doesn't risk something ''else'' killing them first. In this case her extreme hobbies (not related to [[:Category:My Hobby|Randall's hobbies]]).
*Panel 13: Randall's wife sits on an examination bed, listening to a doctor [[Ponytail]] holding a clipboard. The doctor talks about an issue which is "probably nothing" but ''might'' be the cancer -- again showing the paranoia that comes with cancer. Ponytail tells her not to worry about until they have the result of a full scan she will order for her. This could be a full body {{w|Positron emission tomography|PET scan}} to ensure there are no active {{w|lymph node|lymph nodes}}. If there are this could be caused be {{w|metastasis}} of the cancer to the {{w|lymphatic system}}, which would often be impossible to cure. In the first comic we see that it is very difficult to wait for the reply of such a scan.
*Panel 14: Randall and his wife stand above a deep pond full of fish and other objects. Randall's wife is piloting a wired underwater camera with lights. Randall shared pictures of his [https://blog.xkcd.com/2010/11/05/submarines/ underwater ROV] before. If this panel can be taken as following directly after the previous, it could be concluded that after some years they have learned to go do something fun rather than sit and worry for a result that they cannot change and do not know when will arrive. That would be a positive take on the sequence.
*Panel 15: Randall and his wife are standing next to each other. Randall's wife has shoulder-length hair covering most of her face, and observes that, despite the chemotherapy robbing her of most of her hair six years ago, it is now growing enough to obscure her face. "The little girl from ''The Ring''" refers to {{w|Sadako Yamamura}}, the antagonist of the {{w|Ring (novel series)|''Ring'' series}} by {{w|Koji Suzuki}}, and popularized in a {{w|The Ring (2002 film)|2002 movie}}. See the title text,
*Panel 16: A line of six people, Ponytail between two other [[:Category:Multiple Cueballs|Cueball-like]] characters as well as Randall and his wife, with [[Megan]] to the right, stand and watch the corona of the Sun during the totality of the {{w|Solar eclipse of August 21, 2017|total solar eclipse of 2017}}. This has already been mentioned in [[:Category:Total Solar Eclipse 2017|several comics]] earlier in 2017, where this {{w|solar eclipse}} passed over the entire continental USA.
*Panel 17: The sky has been brightened, and the eclipse is over. As the eclipse is cool to see in person (as Randall made clear in [[1880: Eclipse Review]]), the onlookers are left with little more than exclamations of amazement, one of which comes from Randall's wife, which 7 years ago had not expected, or even thought that she would be here to watch it (or a bit earlier, had doubted that she would be!)
*Panel 18: Randall and his wife are walking together and holding hands. When his wife inquires about the next total eclipse, Randall replies that the next one is in seven years (2024), and asks whether they should go to see it.
*Panel 19: Still walking, Randall and his wife think together about a timeline. Seven years have passed since 2010, represented with a solid line from the past to 2017; seven years in the future will be 2024, represented with a dotted line into the future and surrounded by three question marks. This is reflective of Panel 6, where "next year" is not guaranteed to be a thing.
*Panel 20: The pair keeps walking, with his wife optimistically agreeing to this stating that she will do her best to accomplish this, and Randall states that they have a date! (His way of claiming her to still be there in seven years!)

The title text is a continuation to panel 15 concerning the horror movie ''The Ring''. Specifically, watching the videotape in ''The Ring'' is supposed to kill a person in seven days, but the title text instead says "seven years".

With all these thoughts in mind, there is no wonder that he wishes to participate in helping a colleague's cancer-stricken sister with the [[Design of xkcd.com#Unique header text|unique header text]] above this comic, as mentioned above.

==Explanation==
Before starting xkcd, [[Randall]] worked on robotics at {{w|NASA}}'s Langley Center. This drawing was apparently made during that period, while attending a talk that he didn't like.

The name of the comic is a portmanteau-like play on the following:
* {{w|Gödel, Escher, Bach}} is a book by {{w|Douglas Hofstadter}}. He is an American author who has written several books about philosophy, mathematics, and science. This particular book is his most famous one, about "strange loops", self-reference, and recurring patterns, partially shown through the works of the three people in its title:
** {{w|Kurt Gödel}} was a 20th-century mathematician most famous for proving that in our commonly used axiomatic systems, there are true propositions that cannot be proved from the axioms. His proof used a self-referential paradox.
** {{w|M. C. Escher}} was a 20th-century artist most famous for mathematically-inspired engravings of tessellated animals, impossible scenes, [http://philosopherdeveloper.files.wordpress.com/2011/01/devilsangels.jpg fractals], and so on. The form of this strip resembles one of his [http://upload.wikimedia.org/wikipedia/en/2/2c/Escher,_Metamorphosis_II.jpg Metamorphosis etchings].
** {{w|Johann Sebastian Bach}} was a German composer and musician from the Baroque Period, famous for numerous works such as the Brandenburg Concertos.

* Kurt Halsey is a comic artist from Oregon. His work often contains introspective philosophical musings. At least one phrase in the letter is attributed to Halsey, "The past is just practice".

The comic is drawn in the form of a {{w|storyboard}} and is clearly intended to be visualized as an animated sequence.

In the first part of the comic, two people discuss the difficulty of comparing past and present generations, since the person making the comparison invariably belongs to one of the two groups.

It's unclear whether the behatted guy is [[Black Hat]], because Randall hadn't standardized his character designs yet. The sarcastic comment suggests that it is. If it is, then this would be his first appearance. (He also appears in [[12: Poisson]], but that comic was released about 3 months later, but the numbering did not follow the release day on [[LiveJournal]] when the comics were transferred to xkcd - see the [[12: Poisson#Trivia|trivia]] for that comic.)

The assembly of text panels found in the middle of the strip is similar to his [[124: Blogofractal]].

The philosophy of Kurt Gödel is also a theme here: [[468: Fetishes]].

==Interpretations==

* The bubbles may illustrate ideas, memories, or subjects that one could wonder about. In the context of the boring talk, this would mean that Randall is lost in thoughts and gradually loses focus of things going on around him. He sees the talk as mundane, as a part of so many other "subject bubbles".
** Even the comic vertical lines (and therefore the strip's structure) seem to lose their sense to Randall as they collapse and become part of the scene, eventually merging three panels into one. They later reappear for the last six panels.
* The big bubble pushing the small ones further outside may demonstrate how shallow the surface bubbles are to him, or represent an infinite (or very large) number of small bubbles.
* The quote stating "There's too much. And so little feels important." tells us that he feels overwhelmed by the world, maybe by information given in the NASA talk or by events in his life. He recognizes what is important to him, and he feels that it is small compared to the size of the worries of the world (or the big bubble). He may have experienced a sort of existential crisis before turning to his feeling of love in the last panels, when asking himself, "What do you do?".
* The structure of the strip has some abstract connections with the structure of the book. The beginning, middle, and end sequences reflect back on themselves; the strip displays some symmetry. In the book, there's an interplay of contributions from the artist, the musician, and the mathematician; some of this is present in the strip [Lots of citations missing].
* The biggest bubble is expanding, and on it is a fractal arrangement of articles describing various scientific and philosophical discussions. A subjective interpretation is that the fractal nature of the excerpts are a comment on the unending attempt to rationalize and justify the unchanging nature of humanity. The largest bubble bursts, leaving the two figures on a shred of what once was. The final question is, "What do you do when the bubble bursts?" It seems that his answer is to find someone and love them; in the end, that's all that matters. The rest is just air.

==Transcript==
:Drawn during an unending NASA lecture
:[Two people are talking, one in a hat.]
:Cueball: it's just so hard to compare kids now with kids in the past. you can't help but to belong to one group or the other.

:Cueball: and of course every generation seems awful to the one before it. look at quotes from throughout history.

:Hatted: yeah, and it sure would be nice to have some historical perspective on some of this stuff. I just don't know what to make of it.
:[Circles are appearing--maybe snow?]

:Cueball: i guess you do what you can to help the people around you and hope it turns out okay.

:Cueball: in the end, what else can you do?

:Hatted: lead a crusade?

:[We can no longer see the people, just the circles.]
:it's presentism, man. the idea that historical context is irrelevant, that we understand it

:all that we need take no warnings from the follies of the past. that we're facing something new.

:socrates couldn't imagine the internet. but people don't change.
:[We can start to see a darker circle in the lower right corner.]

:(The borders between the three panels on this line are cracking.)
:have you seen those collections of historical pornography? talk about historical context.

:did you know the first porn photo was bestial in.
:[inside a circle:] nature?

:at least that stuff was out of the mainstream
:[each word in one circle:]
:no
:just
:in
:history

:(the three panels have merged into one on each row.)

:i don't know about you, but
:[circled] I
:[uncircled] never

:even once seen

:[The circles are highly variable in size now, and pressed up against a larger one on the right side.]

:[There is mass of circles of different sizes, with some dark fissures in between, against the side of a large circle which we can see part of in the right half of the panel. They look like cells. There's a tiny square in the center of the giant cell.]

:[We see only the tiny square, centered. It has a few marks inside it.]

:[Closer, the square is divided into rectangles of different sizes, each of which has text in it.]

:[Much closer, we can see fragments of the text. Some are sideways, some are cut off, some are too small to read.]
:machine language translated by principles of isomorphism it is a consequence of the Church-Turing thesis that ...
:but how do you select the channel you wish to se-
:thou ... shou ... palin ... stri ... it is a ... crab ...
:be obvious to one-s ... your great intellectual achievements ... Tortise. Why ... you give this old Tortise ...

:[Closer still, we can just see a huge sideways s and h.]

:[Those letters are faded and mixed with a faded version of the next panel.]

:girls take boys away ...
:never be further than a phone call and a goosebumped shiver away ...
:drove all night listening to mix tapes ...
:the past is just practice
:[There is a heart at the bottom and, in the lower left, the name Curt.]

:[The same as the previous panel, but with the words blurred out to scribbles.]

:[Jagged, shaded shapes and strands start to fall. Faint panel borders appear again. There is a person on the far right.]

:(Back to three panels per row.)
:[Cueball and Megan are standing amid the fragments.]

:Man: There's too much. And so little feels important.

:[The jagged edge of the shaded area is encroaching on the sides of the panel.]

:What do you do?

:[We see them from farther away through a rough hole in the shaded area. Bits continue to fall around them.]

:[They are holding hands.]

==Trivia==
*This was the 6th comic originally posted to [[LiveJournal]].
**The previous was [[1: Barrel - Part 1]].
**The next was [[13: Canyon]].
*Original title: "Strip series"
*Original [[Randall]] quote:
::"One of a series of strips I drew during a long and boring NASA lecture. It careens wildly from intellectual to chaotic to Godel, Escher, Bach to Kurt Halsey to chaotic and sappy.
::
::The whole series is here. "
*The last word "here" is a now broken link: <nowiki>http://www.xkcd.com/comic/comic.html</nowiki>
**It was the first time Randall posted a link to the xkcd.com site (so the xkcd page was already active when he posted his first comics to LiveJournal).
**The link indicates that the image posted on LiveJournal was only part of this strip.
**Unfortunately, both the image of this strip and the link posted on LiveJournal are broken (also in the archive).
**So it is not known if there is even more to this strip than now posted on xkcd or if the original post only covered a small part of this very long strip. In that case, the link would take the user to the full comic, the one here, which was later posted on xkcd.
**If anyone knows which of the above is true, please make a comment here. (Do edit, but make sure to indicate that this is a fact then).
*This was one of the [[:Category:First day on LiveJournal|thirteen first comics]] posted to LiveJournal within 12 minutes on Friday, September 30, 2005.
*This comic was posted on [[xkcd]] when the web site opened on Sunday the 1st of January 2006.
**It was posted along [[:Category:First day on xkcd|with all 41 comics]] posted before that on LiveJournal as well as a few others.
**The latter explains why the numbers of these 41 LiveJournal comics ranges from 1-44.

Talk:1774: Adjective Foods

Nobody has edited since I started this? Wow. I must have been ''early''. It's been {{#expr:{{#time:i}}}} minutes! [[User:Jacky720|That's right, Jacky720 just signed this]] ([[User talk:Jacky720|talk]] | [[Special:Contributions/Jacky720|contribs]]) 15:23, 19 December 2016 (UTC)

This looks just like all the food in my supermarket. I'm not even sure if I'm buying food or the best adjectives sometimes XD [[User:Fox Holmes|While most people have mass on Saturday, I have mine relative to my inertia]] ([[User talk:Fox Holmes|talk]]) 15:59, 19 December 2016 (UTC)

The can of Lite is a real thing, of course, and trademarked, which is why other beers can call themselves "light" but not "Lite". [https://www.beeradvocate.com/mag/2627/lite-beer-vs-light-beer/ This article has more on that.] [[Special:Contributions/162.158.75.4|162.158.75.4]] 16:05, 19 December 2016 (UTC)

Italics is totally fine, and Glazed and Lite ''are'' in white. [[User:Jacky720|That's right, Jacky720 just signed this]] ([[User talk:Jacky720|talk]] | [[Special:Contributions/Jacky720|contribs]]) 16:13, 19 December 2016 (UTC)
:First off, I would like to apologize, my reason for changing the text to normal could be seen as inflammatory, and that was not my intention. As for my actual reason, it's that while you may be able to read it fine, many people can't read text like that. In the comic, it's large and capital letters, but the wiki has small text. Adding all that guff makes it hard to read. For example, my mom has awful eyes, and text like that would be virtually unreadable to her. It was not for my sake, but rather for the sake of others.

::It's not hard to increase the font size on a computer -- just ctrl and + (or ctrl and =). ctrl and - to turn it back down. The transcript is mainly there for search engines anyway, I imagine; after all, the comic is directly above it on the same page.[[Special:Contributions/108.162.237.178|108.162.237.178]] 17:29, 19 December 2016 (UTC)
:::it isn't hard to increase font size, but that's not what I'm talking about. I'm talking about how busy the text is. There is no reason for it to have that much. It distracts from the real purpose and decreases readability. Also, they want it edited as well. Note the box above the transcript about format. This is not about you. It needs to change for other people who cannot read this stuff as well. What makes you think everyone knows how to increase font size? I honestly didn't until now. You need to do something about it, I'll do it for you, which you may not like.[[User:Fox Holmes|While most people have mass on Saturday, I have mine relative to my inertia]] ([[User talk:Fox Holmes|talk]]) 17:48, 19 December 2016 (UTC)

Is "artisenal" even a word? Is that a purposeful misspelling of "artisanal"? (Like "lite" is a purposeful misspelling of "light".) [[User:Imperpay|Imperpay]] ([[User talk:Imperpay|talk]]) 16:42, 19 December 2016 (UTC)

The "artisenal" error has now been fixed in the updated comic. [http://xkcd.com/1774/]. --[[User:Esterhazy|Esterhazy]] ([[User talk:Esterhazy|talk]]) 17:42, 19 December 2016 (UTC)

The 'p' by a "kosher mark" indicates that it is kosher for Passover. It will say 'pareve' outright if the food is pareve. --Hamotron[[Special:Contributions/172.68.54.28|172.68.54.28]] 18:24, 19 December 2016 (UTC)
