&amp;quot;There is a common psychological phenomenon which causes people to mentally magnify their own flaws, while failing to notice the flaws of others.&amp;quot; '''Tell that to my ex-wife!''' --[[User:Dangerkeith3000|Dangerkeith3000]] ([[User talk:Dangerkeith3000|talk]]) 15:03, 20 September 2013 (UTC)&lt;br /&gt;
:There is a common psychological phenomenon which causes future ex-wives to mentally magnify their spouse's flaws while failing to notice their own or the flaws of others.  [[Special:Contributions/173.245.55.63|173.245.55.63]] 17:41, 15 July 2014 (UTC)&lt;br /&gt;
&lt;br /&gt;
This comic wierdly mirrors (in contrast) a recently broadcast radio programme (which I doubt Randall will have heard, it being UK's BBC Radio 4 &amp;quot;Thinking Allowed&amp;quot;, I think it was, with a segment regarding how normal people react to those not acting 'properly' to social norms) in which the phenomena was mentioned.  A lady hostess who unselfconsciously apologises for &amp;quot;not having dusted&amp;quot; (despite dust being possibly shed skin cells and such, it's considered &amp;quot;clean mess&amp;quot;), for her visitor, is then utterly mortified when said visitor breaks the rules and also 'helpfully' points out a coffee-ring stain (considered &amp;quot;dirty mess&amp;quot;, for some reason) upon a surface.  Doubtless the traditional light and largely insignificant layering of dust possibly somehow prevents highlighting any ''geniuinely'' missed spots (if one had actually dusted ''most'' of the room), yet distinct stains and marks (and dust layers with obvious finger-marks in?) ought to have been cleaned or even prevented in the first place.&lt;br /&gt;
&lt;br /&gt;
(For the record, my own home is a &amp;quot;working mess&amp;quot;, much to the chagrin of my mother when she visits.  It could definitely be tidier, and there's absolutly no way to convincingly apologise for its state.  I consider the whole place to be my &amp;quot;shed&amp;quot;, in the grand tradition of &amp;quot;shedology&amp;quot;.  Mind you, this attitude of mine arises out of the tendency for me to ''lose'' so many things when I deliberately tidy up/pack away &amp;quot;projects in progress&amp;quot; for such esteemed visitors.  Better that I can find everything when I need to, IMO.  This ''mostly'' works better than with the alternative, under a sometimes Holmesian 'stratified' surface-based filing system.)

http://www.theonion.com/articles/man-puts-glass-of-water-on-bedside-table-in-case-h,33751/ {{unsigned ip|173.14.162.93}}&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
People call a clean house messy as a way to seem superior to their guests. They clean it before the guest gets here then say that because they know the guest has not cleaned. [[Special:Contributions/184.66.160.91|184.66.160.91]] 17:37, 22 September 2013 (UTC)&lt;br /&gt;
:Maybe - sometimes. But also, I think it stems from the insecurity of possibly being judged by your guest: in this case, you're saying basically &amp;quot;if my cleanliness doesn't live up to your standards, it's not because my standards aren't as high as yours, it's just because I haven't finished cleaning.&amp;quot; [[User:L-Space Traveler|L-Space Traveler]] ([[User talk:L-Space Traveler|talk]]) 14:30, 16 January 2023 (UTC)&lt;br /&gt;

&amp;quot;There is a common psychological phenomenon which causes people to mentally magnify their own flaws, while failing to notice the flaws of others.&amp;quot; How is this phenomenon called? [[Special:Contributions/79.227.152.95|79.227.152.95]] 09:36, 23 September 2013 (UTC)&lt;br /&gt;

:No, more like self doubt, which is the exact opposite.  [[Special:Contributions/108.162.219.58|108.162.219.58]] 09:50, 4 February 2014 (UTC)&lt;br /&gt;
I think you mean &amp;quot;What is this called?&amp;quot;  I don't know, I've been trying to research it for the last five years and it's never the first result on google.  Must not exist. [[Special:Contributions/72.94.35.160|72.94.35.160]] 02:37, 25 September 2013 (UTC)&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
&amp;gt;&amp;gt;&amp;quot;In the title text, Cueball's anxiety in further amplified when he recalls that he left out a glass of water from the night before. &amp;quot;&lt;br /&gt;
 &lt;br /&gt;
I do not think this is right. I think it is the host who is apologizing about the glass of water as the apology is in quotes. [[Special:Contributions/108.162.241.178|108.162.241.178]] 01:34, 24 October 2017 (UTC)&lt;br /&gt;
  I agree with the idea that it is the host apologizing for the water.&lt;br /&gt;
&lt;br /&gt;
I just noticed, that the picture on the wall is the same motive as in [[1159: Countdown]] (where it even takes multiple lines and different speculations in the explanation), and possibly the one from [[4: Landscape (sketch)]]. Are there more comics containing this motive for a drawing/picture? --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 11:48, 22 October 2019 (UTC)&lt;/div&gt;</summary>

&amp;quot;0-3 - babies/toddlers are not self-sufficient and not intelligently communicative.&amp;quot; Babies at age 2 can communicate pretty good.(And some older people cannot &amp;quot;intelligently communicate&amp;quot;.

&lt;br /&gt;
: I believe the idea is that most 2-to-3-year-olds are only capable of communicating things that could be boiled down essentially to either &amp;quot;I want that&amp;quot; or &amp;quot;I don't want that&amp;quot; (at varying levels of intensity and repetition). This is not generally considered &amp;quot;intelligent&amp;quot; communication - indeed most of the phylum chordata is capable of this level of communication. -- [[User:Brettpeirce|Brettpeirce]] ([[User talk:Brettpeirce|talk]]) 14:33, 21 March 2014 (UTC)&lt;br /&gt;
&lt;br /&gt;
:: As a father. That's just BS. Or I have a genius baby. At 3 she is communicating more than just needs. She communicates fears, dreams, imagines she's a superhero, can count to 20, and can point out logical fallacies. She understands when I'm away on business, and can understand that I cannot interact with her physically. However, right afterwards she'll pretend I can interact with her and will run from the phone. She is sentient. I have reason to believe they are capable of these thoughts at even younger age, just unable to speak their minds.

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by 2 Turtle Bots - Please change this comment when editing this page. Do NOT delete this tag too soon.}}&lt;br /&gt;
Advent calendars are a form of countdown where you get a small present (traditionally, just a thematic picture or chocolate) every day until Christmas. While the religious season of {{w|Advent}} traditionally begins four Sundays before Christmas, most Advent calendars begin on December 1st for simplicity.&lt;br /&gt;
&lt;br /&gt;
In this comic, Randall has devised an Advent calendar that contains multiple smaller Advent calendars, each of which contains the same number of items as there are days left until Christmas. By the time he reaches Christmas, he will have 325 different items, or 350 if counting the sub-calendars. &lt;br /&gt;
&lt;br /&gt;
For the Advent calendar Advent calendar, each day a number of items equal to the number of days left until christmas are added.  Once we reach the 8th day of Christmas, the song’s growth rate exceeds the calendar’s. There are 325 items total in the 12 Days of Christmas.&lt;br /&gt;
&lt;br /&gt;
It is not clear what is inside each sub-calendar. The usual filling would be chocolate, however it could also be possible that the advent calender advent calendars had even more advent calendars within.&lt;br /&gt;
&lt;br /&gt;
The title text refers to {{w|The_Twelve_Days_of_Christmas_(song)|The Twelve Days of Christmas}}, a traditional Christmas carol in which the singer receives many gifts from their paramour for each day of the Twelve Days of Christmas. On day one, they receive one gift, and on day ''n'', they receive again all the gifts they received on day ''n-1'', plus ''n'' copies of a new gift. The exact gifts given each day vary by version of the song, but the result is that the number of gifts given each day follows the [https://en.wikipedia.org/wiki/Triangular_number triangular number sequence]: 1, 3, 6, etc., receiving 78 gifts on day 12, for a total of 364 gifts.&lt;br /&gt;

{{incomplete transcript|Do NOT delete this tag too soon.}}&lt;br /&gt;
:[On a grey board, are 23 advent calendars behind large windows, numbered from 3 to 25, plus two open calendars.]&lt;br /&gt;
:[Each calendar numbered n has 26-n squares in it.]&lt;br /&gt;
:[One open calendar has 25 squares, 2 of which are black. The other open calendar has 24 squares, one of which is black.]&lt;br /&gt;

:I like advent calendars, so I got an advent calendar that gives me a new one every day until Christmas.&lt;br /&gt;

I added a basic explanation, how did I do? [[Special:Contributions/172.70.115.129|172.70.115.129]] 14:56, 20 November 2024 (UTC)&lt;br /&gt;
:''pat pat'' Good job.  [[User:Fephisto|Fephisto]] ([[User talk:Fephisto|talk]]) 15:28, 20 November 2024 (UTC)&lt;br /&gt;
I guess chess timers work based on the IERS. [[Special:Contributions/172.71.223.126|172.71.223.126]] 15:32, 20 November 2024 (UTC)&lt;br /&gt;
: See &amp;quot;{{w|Chess_clock|chess clocks}} don't work that way&amp;quot; comment, below. If they did, they would almost certainly reference {{w|Coordinated_Universal_Time|Zulu time}}, which doesn't recognize daylight saving or other local time adjustments. This would go badly for Cueball. Moreover, White Hat could be forgiven for thinking that he had won the game when the clock went &amp;quot;beep&amp;quot; in the third panel, because beeping/flag falling in a chess clock &amp;lt;em&amp;gt;should&amp;lt;/em&amp;gt; signal end of match because Cueball's time had run out (the fourth panel asserts that Cueball's time did not, in fact, expire). A minor additional irregularity in what is already a seriously contrived situation. [[Special:Contributions/172.68.23.91|172.68.23.91]] 20:34, 20 November 2024 (UTC)&lt;br /&gt;
:: The &amp;quot;beep&amp;quot; is probably triggered by the clock falling back from DST rather than going to zero, since we can see in the 4th panel that there are more than 60 minutes left after the change.[[Special:Contributions/172.71.122.111|172.71.122.111]] 11:39, 21 November 2024 (UTC)&lt;br /&gt;
::: 'Zactly. But beeping for any reason other than flag-falling (time expired) would not be expected in a real-world (i.e., not an xkcd-world) chess clock. [[Special:Contributions/162.158.41.98|162.158.41.98]] 17:00, 21 November 2024 (UTC)&lt;br /&gt;
:No, chess clocks don't work that way.  They are simple timers that do not refer to actual time of day in any way, any more than a stopwatch does.  Randall just made it work that way for the sake of the joke. {{unsigned ip|172.71.194.17|20:17, 20 November 2024}}&lt;br /&gt;
::Speaking from the experience of one in a sport where some are seeking to &amp;quot;improve&amp;quot; upon the use of a manual stopwatch/timer process with a computerised replacement (anything from a smartphone to a home-computer, often with a live online connection), I'm seeing several cases where time differences between equipment (e.g. GPS time vs. 'radio'/time-signal time) has caused confusion, never mind the possibility of random external events (...OS Update notifications, AV scans going active, etc) or other external interferences. In ways that would never happen to a dedicated timing device that's not even listening out for a national time-signal broadcast (which I know for certain can suffer from interference).&lt;br /&gt;
::Also, in case anybody is bothered, it's not really a &amp;quot;clock&amp;quot; if it doesn't have a bell (or bells), as per the German &amp;quot;Glocke&amp;quot;/French: &amp;quot;Cloche&amp;quot;. Although possibly a single-match &amp;quot;chess clock&amp;quot; could have such a bell for an audible alert, as well as other mechanical 'flag' indicators. But, often, what most people might call a clock is perhaps more just a &amp;quot;timepiece&amp;quot;. (Watches/stopwatches/timers/etc, is another matter of sub-distinction, which I try not to be too confusing, or even wrong, about.) [[Special:Contributions/172.69.194.226|172.69.194.226]] 00:53, 21 November 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
If white hat had conserved 20 seconds through the course of the game, they would have won. Cueball must have been sweating if they were relying on this strategy. [[User:Radialsymmetry|Radialsymmetry]] ([[User talk:Radialsymmetry|talk]]) 15:35, 20 November 2024 (UTC)&lt;br /&gt;
:Cueball may have been deliberately letting the time run down on this move for quite a while, so that it would have greater effect when the change happened at almost the last second.[[Special:Contributions/172.70.85.126|172.70.85.126]] 12:21, 21 November 2024 (UTC)&lt;br /&gt;

&amp;lt;br/&amp;gt;I believe that's the only one that straddles the Arizona border with a Pacific Time Zone state (California and Nevada), so (head-)canonically, that's where the comic is set. {{unsigned ip|172.69.6.190|17:15-26, 20 November 2024}}&lt;br /&gt;

&lt;br /&gt;
Is the neighbouring state {Utah or New Mexico} or {Nevada or California}? I'm not from the US so I'm not sure how your rules work. 172.69.6.190 above seems to think it's the latter but aren't they both on Mountain Time before the clocks change? {{unsigned|Mtcv|08:57, 21 November 2024}}&lt;br /&gt;
&lt;br /&gt;
One difference between the way parts of North America change time and the way parts of Europe do is that the various North American time zones fall back/jump forward at 2AM local time, while European time zones all change at the same instant (01:00 UTC/WET (02:00 CET, 03:00 EET). That means that the same &amp;quot;trick&amp;quot; could work by sitting on the line between any American time zones at the changeover, but not by sitting on the European lines.

:In the US this would not work, since the time would be different over the time zone, and thus the chess clocks that are based on the actual time would run different before. In Arizona there are the situation that only the other state changes it's time. This would work for instance on the border to Nevada, where the two states have the same time in the summer as Nevada's timezone is one hour behind Arizona but then the same time during daylight saving time. Thus sitting in the border house on the Hoover dam it would be possible for the one on the west side to be in Nevada and the east side in Arizona. And when DTS stops, the one in Nevada would gain an hour, but not the one in Arizona. And before they would have had the same time. This would thus also work in Europe if one country did not use DTS and the other did along a time zone border. And this will only work when DTS ends. As it happens have only been in the US once, taking a course in Las Vegas. But on the one day off we took a road trip to Gran Canyon and passed Hoover Dam. And then we drove over a time zone line, the only time I have tried that... And then the time did not change due to the lack of DTS in Arizona... What a disappointment... :-) But the rest of the trip was great. Crazy places the dam and Gran Canyon. (As well as Las Vegas, living in a hotel on the Strip). Also just watched the TV series The Queens Gambit where chess timers are used extensively, and of course they do not work digitally. But I love one more of Randall's quibs against the stupidity of DTS. Can't wait till we stop with that stupidity. ;-) Great TV series by the way! --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 14:42, 21 November 2024 (UTC)&lt;br /&gt;

A related oddity occurs in the City of The Gold Coast, in Australia, which straddles the Queensland/New South Wales border. The border runs through a built up area, and as NSW has DST but Queensland does not, there are places that are, for one hour each year, in different years, despite being only a few metres apart. You can celebrate the New Year at a bar in Tweed Heads, then cross the road to a bar in Coolangatta, and celebrate the New Year all over again an hour later. I believe this is the only border in the world that runs through a built up area and has different timezones at New Year; New Year being in winter in the Northern Hemisphere means that such DST related anomolies are strictly a Southern Hemisphere phenomenon.

I couldn't inagine the difficulties of setting a lunch date with a group and having to confirm the timezone as well as the time, every single time. In most locations with cross-border cities, the smaller one is permitted to observe the time zone of the larger one, allowing Gary Indiana to watch Chicago television on &amp;quot;local time&amp;quot;.

: ... but seriously, folks, there's no telling what the game position is from the cartoon. If one takes the drawing at face value (dangerous, given its low resolution and angle of presentation), then it is &amp;lt;em&amp;gt;White&amp;lt;/em&amp;gt;, not Black, who is up a piece (what piece cannot be determined). Inference that White Hat is Black is from the tallest pieces on the board (presumably the Kings) being Black on White Hat's side of the board, and White on Cueball's. Even that's chancy. The least risky guess is that both Queens are off the board. [[Special:Contributions/172.68.23.82|172.68.23.82]] 01:07, 22 November 2024 (UTC)&lt;/div&gt;</summary>

&lt;br /&gt;
The ''{{w|Europa Clipper}}'' space probe was launched from the {{w|Kennedy Space Center}} in Florida on [https://europa.nasa.gov/mission/about/ October 14, 2024]. It is expected to arrive at Jupiter and begin exploration of Jupiter's moons, particularly {{w|Europa (moon)|Europa}}, in April of 2030. &lt;br /&gt;
&lt;br /&gt;
Europa is an icy moon. Water ice covers its surface. Around 15 to 25 kilometers (10 to 15 miles) beneath the ice, there is expected to be liquid water which may contain some [https://europa.nasa.gov/why-europa/ingredients-for-life/ basic forms of life]. To sample this liquid, its icy crust would need to be breached. The thickness of the ice dwarfs the ''Europa Clipper's'' 31 meter span.&lt;br /&gt;
&lt;br /&gt;
Europa's surface of ice over liquid water can be compared to the caramelized crust on the popular dessert {{w|crème brûlée}}, perhaps because the {{w|Cassini-Huygens}} probe, after landing on Saturn's moon Titan in January of 2005, found that its surface had what was described as [https://www.sciencenews.org/article/world-unveiled-cr%C3%A8me-br%C3%BBl%C3%A9e-titan a &amp;quot;crème brûlée&amp;quot; consistency]. The hard surface of the caramel cream dessert is traditionally cracked open with a spoon, and so [[Randall]] posits that such equipment will be deployed by the ''Europa Clipper''.&lt;br /&gt;
&lt;br /&gt;
In truth, no such spoon is present on the probe, and Europa's icy crust is too thick to be penetrated by a spoon of such size. Advanced measures are needed to prevent contamination of liquid water by Earth's organisms such as {{w|tardigrade}}s, {{w|deinococcus radiodurans}}, or {{w|bacillus subtilis}}. The ''Europa Clipper's'' course has been charted to avoid any contact with the surface of Europa (although it will fly through some sparse material it ejects into space) so as to prevent {{w|Planetary protection|contamination by microorganisms from Earth}}.&lt;br /&gt;
&lt;br /&gt;
The successful deployment of any spacecraft's instrument is considered a cause for celebration because deployable spacecraft instruments often fail to correctly extend, unfurl or undock. The ''Clipper'' has a magnetometer that will be used at the end of a 8.5 meter boom (not apparent in the comic which, spoon extension aside, is an otherwise fairly accurate depiction) as part of its study of the moons' environment.&lt;br /&gt;

In {{w|Greek mythology}}, {{w|Europa (consort of Zeus)|Europa}} was said to be a {{w|Phoenician}} princess who {{w|Zeus}}, the king of the gods, abducted after transforming himself into a bull. The name of the continent Europe derives from a northern province and/or river of ancient Greece that may have been associated with this legend.

Jupiter's moon was thematically {{w|Europa (consort of Zeus)#Moon of Jupiter|named after the princess}} in relatively recent times, much as the {{w|Tethys (mythology)|Oceanid Europa's mother}} features in a differently themed naming of Saturnian moons. With the caramel cream dessert believed to have been [https://archive.org/details/lagastronomieaug00sabb/page/272/mode/2up invented in Europe], there is an extremely vague and contrived possibility that mythology, rather than any more mundane cullinary analogy, could have inspired [[Randall]] to start down the path of eventually suggesting that the spacecraft may encounter crème brûlée and require a spoon.&lt;br /&gt;

A mission goal is to achieve a 6:1 {{w|orbital resonance}} with Europa by September 2034.[https://www.researchgate.net/profile/Martin-Ozimek/publication/383115312_AAS_24-433_Europa_Clipper_Mission_Analysis_Pump_Down_Trajectory_Design/links/66bcd845311cbb094938dbd6/AAS-24-433-Europa-Clipper-Mission-Analysis-Pump-Down-Trajectory-Design.pdf] ]]&lt;br /&gt;
&lt;br /&gt;
The ''{{w|Europa Clipper}}'' space probe was launched from the {{w|Kennedy Space Center}} in Florida on October 14, 2024. It is expected to arrive at Jupiter and begin exploration of Jupiter's moons, particularly {{w|Europa (moon)|Europa}}, in April of 2030. &lt;br /&gt;
&lt;br /&gt;
Europa is an icy moon. Water ice covers its surface. Beneath the ice, there is expected to be liquid water, which might contain some basic forms of life.[https://europa.nasa.gov/why-europa/ingredients-for-life/] To sample this liquid, its icy crust would need to be breached.&lt;br /&gt;
&lt;br /&gt;
Europa's surface of ice over liquid water can be compared to the caramelized crust on the popular dessert {{w|crème brûlée}}, perhaps because the {{w|Cassini-Huygens}} probe, after landing on Saturn's moon Titan in January of 2005, found that its surface had what was described as [https://www.sciencenews.org/article/world-unveiled-cr%C3%A8me-br%C3%BBl%C3%A9e-titan a &amp;quot;crème brûlée&amp;quot; consistency]. The hard surface of the caramel cream dessert is traditionally cracked open with a spoon, and so Randall implies that this equipment [https://europa.nasa.gov/mission/about/ will be used] by the ''Europa Clipper''.&lt;br /&gt;
&lt;br /&gt;
In truth, no such spoon is present on the probe, and the ice-layer would be far too thick to be so easily penetrated by the illustrated size of cutlery. More than that, its course is explicitly designed to avoid contact with Europa (though it will fly through sparse material ejected into space from it) so as to prevent {{w|Planetary protection|contamination by microorganisms from Earth}}. The successful deployment of ''any'' instrument is considered a cause for celebration, however, as deployable instruments on spacecraft have often failed to correctly extend, unfurl or undock, and the craft is equipped with a magnetometer that will be used at the end of a 8.5 meter boom as part of its closer studies.&lt;br /&gt;

&lt;br /&gt;
==Trivia==&lt;br /&gt;
Initially, the ''Europa Clipper'' mission was planned to include a lander component, but it was removed from the project early on. As of now, the Europa Lander proposal lags significantly behind the Clipper in development and has not secured funding. An actual sample return mission is currently far into the future of {{w|Ocean Worlds Exploration Program|the pertinent plans for exploration}}.&lt;br /&gt;
&lt;br /&gt;
In Arthur C Clarke's novel '''2010''', the monolith aliens tell humanity ''&amp;quot;All these worlds are yours - except Europa. Attempt no landing there.&amp;quot;'' Contrary to the suggestion of the comic, no landing or any other physical interaction beyond observation of the surface of Europa is planned.&lt;br /&gt;
&lt;br /&gt;
In {{w|Greek mythology}}, {{w|Europa (consort of Zeus)|Europa}} was said to be a {{w|Phoenician}} princess who {{w|Zeus}}, the king of the gods, abducted after transforming himself into a bull. The name of the continent Europe derives from a north-western province of ancient Greece that may have been associated with this legend. Jupiter's moon was {{w|Europa (consort of Zeus)#Moon of Jupiter|named after her}} in relatively recent times. With the caramel cream dessert believed to have been [https://archive.org/details/lagastronomieaug00sabb/page/272/mode/2up invented in Europe], this could explain why [[Randall]] suggests that the spacecraft may encounter crème brûlée and require a spoon.&lt;br /&gt;

I'm not brave enough to actually add an explanation myself, quite yet, but ...

:: The issue of the continent and the moon coming from the same classical source (for different reasons) rather stretches the link between the dish (from the country, from the country's region/continent, from the region of Greece, ''possibly'' from the pantheon) and the moon (directly from the pantheon). I agree with the 'stretch' assessment. You can probably find easier and more plausible (but wrong) links worth alluding to than that, which relies upon several steps and a ''possible'' polysemic pair of original links.

::I can ''not'' believe I got ChatGPT to make this for me:&lt;br /&gt;
{{cot|You have been warned}}&lt;br /&gt;
So, here's the thing about Zeus and Europa, but told from a kind of career-minded, millennial perspective:&lt;br /&gt;
&lt;br /&gt;
Europa was this smart, ambitious woman just trying to make it out there in the Mediterranean startup scene. She had her plans, her own thing going on, some solid friends, and a bright future. She wasn’t looking for anything too complicated; she just wanted to keep her options open and figure out her next big move.&lt;br /&gt;
&lt;br /&gt;
Enter Zeus. Now, picture him as that intense CEO type—big, powerful, kind of legendary for his influence (and his *questionable* reputation). He’s been around the block a few times, always looking for the next exciting project or, well… person. Zeus saw Europa, and she was exactly his type: sharp, resourceful, had a lot of potential. He was like, &amp;quot;Yeah, I need *that* in my portfolio.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
But Zeus was a little extra with his tactics. Instead of just, you know, scheduling a coffee chat or reaching out on LinkedIn like a normal person, he came up with this elaborate scheme. He disguised himself as this beautiful white bull (yeah, Zeus was *that* guy who would make things way more complicated than necessary). He wandered down to the shore near Europa and her friends, looking majestic and mysterious, and let her come to him.&lt;br /&gt;
&lt;br /&gt;
Europa, understandably, was like, &amp;quot;This bull is kind of weirdly friendly and actually pretty cool.&amp;quot; She got curious, went closer, and Zeus played it super smooth, staying calm and approachable. When she got comfortable enough, she even climbed onto his back for a ride—just for fun! I mean, who hasn’t hopped onto a crazy idea because it seemed cool at the time, right?&lt;br /&gt;
&lt;br /&gt;
But then things got wild. Suddenly, Zeus took off, sprinting across the beach and straight into the sea. He didn’t just want to show her the local scene; he was taking her across the entire Mediterranean to Crete, like some super intense onboarding retreat she hadn’t signed up for. By the time they got there, she was probably exhausted, confused, and questioning her life choices.&lt;br /&gt;
&lt;br /&gt;
And here’s the kicker: once they arrived, Zeus was like, “Oh hey, it’s me! Not just some chill bull—surprise, I’m Zeus.” At this point, Europa realized she was in way deeper than she’d ever expected. She ended up staying in Crete, becoming queen and building a legacy, which, sure, sounds great on paper. But you have to wonder if that’s what she really wanted in the first place, or if she was just swept up in the whirlwind of Zeus's charm and grand promises.&lt;br /&gt;
&lt;br /&gt;
So, in the end, Europa's career ended up in a place she never saw coming. She became a name people would remember for centuries, but not necessarily on her own terms. It’s the classic millennial dilemma: she got a high-profile &amp;quot;role&amp;quot; with Zeus, but did she really get to build her own brand, or was she just another line in Zeus’s impressive (and very long) resume?&lt;br /&gt;
&lt;br /&gt;
Maybe Europa would look back on this “opportunity” and think, “Did I even want this? Or did I just get pulled into someone else’s grand plan?” A classic case of getting lost in the allure of “networking,” and honestly, a pretty good reminder to always check out who’s really behind the bull.&lt;br /&gt;

&lt;br /&gt;
The ''{{w|Europa Clipper}}'' space probe was launched from the {{w|Kennedy Space Center}} in Florida on October 14, 2024. It is expected to arrive at Jupiter and begin exploration of Jupiter's moons, particularly {{w|Europa (moon)|Europa}}, in April of 2030. &lt;br /&gt;
&lt;br /&gt;
Europa is an icy moon. Water ice covers its surface. Beneath the ice, there is expected to be liquid water, which might contain living microbes.[https://europa.nasa.gov/why-europa/ingredients-for-life/] To sample this liquid, its crust (water ice) would need to be broken.&lt;br /&gt;
&lt;br /&gt;
In the comic, Europa's surface ice is likened to the caramel crust on the dessert ''{{w|crème brûlée}}'' which to eat typically has its crust broken with a spoon. The carmel cream dessert is believed to have been [https://archive.org/details/lagastronomieaug00sabb/page/272/mode/2up invented in Europe], after which the moon and the space probe were named. Thus [[Randall]] suggests the spacecraft might encounter crème brûlée, and has therefore been equipped with a spoon for the purpose of collecting samples, as spoons are the traditional {{w|tableware}} provided for eating such desserts. Perhaps because the {{w|Cassini-Huygens}} probe, after landing on the surface of Saturn's moon Titan in January of 2005, found that ''its'' surface had what was described as [https://www.sciencenews.org/article/world-unveiled-cr%C3%A8me-br%C3%BBl%C3%A9e-titan a &amp;quot;crème brûlée&amp;quot; consistency], although there are significant differences between the two moons.&lt;br /&gt;
&lt;br /&gt;
No such spoon is present on the ''Europa Clipper.''{{cn}} Its course is designed to avoid contact with Europa so as to prevent {{w|Planetary protection|contamination by microorganisms from Earth}}. The spacecraft is, however, equipped with a magnetometer at the end of a 8.5 meter deployable boom. Deployable instruments on spacecraft have often failed to deploy correctly, so the successful deployment of any instrument is considered a cause for celebration.&lt;br /&gt;
&lt;br /&gt;
The title text expands on the joke by stating that the spacecraft &amp;quot;had BETTER&amp;quot; return samples of Europa to Earth. However, the ''Europa Clipper'' is not a {{w|sample-return mission}}.&lt;br /&gt;

&lt;br /&gt;
Does the phrase &amp;quot;maximum likelihood&amp;quot; have any relationship to phylogenetics?  [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 03:01, 12 November 2024 (UTC)&lt;br /&gt;
: {{w|Computational_phylogenetics#Maximum_likelihood|Profoundly so}}. Most contemporary analyses, especially of large datasets, use either maximum-likelihood methodologies or Bayesian inference (q.v.). I will see if I can say something coherent and comprehensible about this in the explanation. [[Special:Contributions/172.71.147.58|172.71.147.58]] 03:30, 12 November 2024 (UTC)&lt;br /&gt;

&lt;br /&gt;
&amp;quot;Pointy circle&amp;quot; is, of course, an oxymoron. Randall is also making a joke about how older phylogenetic trees were  based on anatomy, like saying that squares and triangles are close because they have exoskeletons with straight lines and joints. Now, the tree is (where possible) based on genetic similarity. [[User:Nitpicking|Nitpicking]] ([[User talk:Nitpicking|talk]]) 05:10, 12 November 2024 (UTC)&lt;br /&gt;

&lt;br /&gt;
Why was phylogenetic analysis required to establish this relationship? Reuleaux triangles are an intermediate form, demonstrating a close relation between circles and triangles. [[Special:Contributions/172.71.130.208|172.71.130.208]] 06:24, 12 November 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
''Obviously'', he's doing phylogenetics wrong: the pentagons (&amp;amp; hexagons, not shown) should also be shown as descending from the circles. Plus, the ovoids (far more than a middle step between lentiform &amp;amp; triangle, truly an extant branch in their own right) are not represented ''at all''. A major oversight, to cut such corners, given the point he's circling about?   &lt;br /&gt;

&lt;br /&gt;
Someone should add something about how circles and triangles are related through trig in a way that the rest aren't. Sorry I am new to this and don't know how to format my comment correctly.&lt;br /&gt;
&lt;br /&gt;
I'm sure you could develop a 'DNA' sequence for geometric shapes. [Number of active vertices + angle, Number of curves in each side + variation from straight + orientation from centre, thickness of stroke, etc] basically the sort of data in any drawing data of said shape. Thus you could have two circles that look every similar, but one being an extreme Reulaux triangle and the other a 10,000 sided polygon with no side curvature at all! C.f. Swift and swallow!

: The result would be a taxon x character data matrix, the first step in all forms of phylogenetic analysis. On such a small matrix, you could probably perform maximum parsimony analysis by hand, as Hennig did. However, with such a small number of characters per taxon, taxon resolution would probably be low (lots of polytomies instead of fully resolved dichotomies), and [https://wiki.christophchamp.com/index.php?title=Bootstrapping bootstrap support values] would be horrible. The resulting consensus tree would likely be [&amp;lt;em&amp;gt;ahem&amp;lt;/em&amp;gt;] sharply criticized - not least because it would be a &amp;quot;mere&amp;quot; {{w|Analysis_of_similarities|similarity analysis}} and not a true phylogeny (not a reconstruction of descent with modification of progeny).

:Farther - does is mean father back, or further ahead in time? If ahead it could mean Randall do not think there will be any eyes left to see in 500 million years time. Which is not unlikely. Earth will not stay inhabitable much longer than that (probably 800 million years, then the seas will have evaporated). --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 08:30, 7 November 2024 (UTC)&lt;br /&gt;
:A few ways. Fusion likely formed many elements, and neutron star death possibly the rest of the naturally occurring ones. When those started sticking together they would form rocks. The type likely being referred to here is probably sediment being compressed and former a cohesive stone, magma crystalizing, or compression of the latter two types of rocks into different types of rocks.

Oh, I ''like'' that title text. It has a poetic quality. (It refers to when various part of animal anatomy first evolved, but does so in a really nice way.) --[[Special:Contributions/162.158.74.24|162.158.74.24]] 08:47, 7 November 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
I'd suggest that the explanation should at least include the other interpretation of &amp;quot;farther&amp;quot;, namely &amp;quot;farther back in time&amp;quot;.  I think that's the more obvious one, personally: he's saying these rocks are a billion years old, eyes evolved 500 million years ago and that vast abyss of time &amp;quot;stretches back as far as the eye can see ... and then 500 million years farther&amp;quot; [back].  As in, these rocks existed for 500 million years in a world where there were no eyes.  Right?  I don't know how the future got involved, it seems to be pretty clearly about the past.[[User:ModelD|ModelD]] ([[User talk:ModelD|talk]]) 14:25, 7 November 2024 (UTC)&lt;br /&gt;
:Yeah, that description of 'farther back in time' really seems to make more sense here, since the comic talks about how the rocks were there for roughly that long before eyes existed, and it keeps with the poetic, reflective nature of the rest of the comic, while the future interpretation feels like a bit of a jump from one theme to another. [[User:UnbiasedBrigade|UnbiasedBrigade]] ([[User talk:UnbiasedBrigade|talk]]) 15:03, 7 November 2024 (UTC)&lt;br /&gt;
: I concur. This is the interpretation I had before coming to explainxkcd. I think that efforts to make the cartoon be about current events impose a meaning on it that the cartoonist is not yet ready to express. The cartoon appeared very late, and (speaking of imposing a meaning on a cartoon) I imagine Randall struggled mightily to come up with an idea that was not some variation on a fireball of wrath consuming the USA and everything in it. I would also remove the climate-change reference as an overreaching interpretation. For what it's worth, Randall's living depends on computer use by his audience, and computer use is a massive contributor to anthropogenic climate change. I have read repeatedly that, in order to persuade someone to adopt a desired behavior, the proponent has to model it. In this case, by massive reductions in personal energy usage ... which will simultaneously make your life miserable and put you out of the public eye, where no one can see the correct behavior you're modeling. How I learned to stop worrying and love carbon dioxide. [[Special:Contributions/162.158.42.96|162.158.42.96]] 15:13, 7 November 2024 (UTC)&lt;br /&gt;
::Possibly that was my own doomsday mindset. I see it's been edited to correct this. :-D (N.B.: Fwiw, Randall depending on computers does not mean he can't be worried about and active against climate change.) [[User:Transgalactic|Transgalactic]] ([[User talk:Transgalactic|talk]]) 17:21, 7 November 2024 (UTC)&lt;br /&gt;
::: Many (most? all?) of us (profess to) worry about topics such as climate change, and sell actions we (think we) have taken to promote &amp;quot;correct&amp;quot; policy and behavior. My point is that, if the actions we sell do not conform to our daily practices, we present ourselves as clueless at best, and deliberately, and self-servingly, hypocritical at worst. Speaking of last Tuesday ... A Doonesbury cartoon, some (egad) decades ago, which I wish I could find, forcefully made the point, by having a Black man respond to Michael D's pontifications about climate change, &amp;quot;You've [deleted] the world with your energy use, so now &amp;lt;em&amp;gt;we&amp;lt;/em&amp;gt; don't get to have any?&amp;quot; Ultimately, we will say and do anything that makes us look good to our homies ... until it means &amp;lt;em&amp;gt;me&amp;lt;/em&amp;gt;. [[Special:Contributions/172.71.150.179|172.71.150.179]] 18:31, 7 November 2024 (UTC)&lt;br /&gt;
::::Most of those ideas to promote &amp;quot;correct&amp;quot; policy are stupid. The POINT of prevent climate change is to ensure our civilization can continue. If we stop living, figuratively OR literally, who will we be preserving the climate for? I don't really care what shape we leave the Earth in for cockroaches, besides, they won't mind either, they can adapt. Therefore, we need to find a way how to make climate better (or not as bad as currently predicted) WITHOUT destroying ourselves. Most likely it means new technology, because new technology solved MUCH more problems in history than appeal to people's altruism and better self. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 20:19, 7 November 2024 (UTC)&lt;br /&gt;

: There's really no good reason for imaginging the &amp;quot;further&amp;quot; is &amp;quot;further forward&amp;quot; if you've just been talking of looking back. Imagine being given directions to go back towards where you noted a prior landmark and then go further, that wouldn't mean return to here and then go onward again. As such, I've reworded the &amp;quot;future extinction&amp;quot; bit entirely in the other direction (it might mean a different treatment of the &amp;quot;mood explanation&amp;quot; now in the Trivia, but meshes with the comic itself). I pondered adding that, even before 'eyes', there were different phases of light/illumination (and/or shadow) sensitivity that would have meant that day/night (or at least hot vs. cold rocks) and things such as looming predators or overhanging shelter would still have been 'sensed', so being &amp;quot;dark-blind&amp;quot; would have been not necessarily a thing, but instead I just alluded to the Sun still shining (or glowing lava still illuminating, as with the Moon and its pre-fragments whenever they were up above) to aid an actual visit to that era by a time-tourist, and that it's just a selective regression (or a limited degree of retro-posession of any contemporary entity) that leads to &amp;quot;having nothing to see with/by&amp;quot;. But to properly expand these extended philosophies in the Explanation would probably clutter up the existing text too much.

: It seems at least mildly relevant. It's a huge, recent event; of a sort that Randall is known to care a lot about; and the meditative mood being evoked seems appropriate. I wouldn't call it an &amp;quot;election comic&amp;quot; or anything, but the trivial is certainly relevant. [[Special:Contributions/172.69.58.132|172.69.58.132]] 16:18, 7 November 2024 (UTC) &lt;br /&gt;
: I would not be surprised to see this sort of thing unrelated to the current events (it shares a viewpoint given in such as [[1198: Geologist]], which is &amp;lt;s&amp;gt;almost&amp;lt;/s&amp;gt; worth an in-article back reference), but I also think that it's not unlikely that the &amp;quot;mood&amp;quot; of the piece (looking back into &amp;quot;the black&amp;quot;, perhaps) is prompted by what we can assume Randall is feeling about current events.  Not quite the old &amp;quot;Sad Comics&amp;quot; category, but reflective, and different from what we might have seen under more jubilant (for Randall, at least, but also for many others) times down the different trouser-leg of time.

&lt;br /&gt;
I removed the climate change stuff from the Trivia section, since it seems so far removed from this comic.  Tying the meditative mood of the comic to the presidential elections was a stretch, in my opinion, but I left that portion there, as I could see someone making that connection, especially given Randall's political opinions. {{unsigned ip|172.71.154.141|18:48, 7 November 2024 (UTC)}}&lt;br /&gt;
