Dúthomhas:

did anyone else wait for the screensaver to hit the corner? [[Special:Contributions/216.25.182.141|216.25.182.141]] 20:13, 1 April 2026 (UTC)
:Yes. I watched waaay too long to see if it would, but lost patience and I don’t want to put effort into determining if it will happen. Can anyone confirm whether or not it will eventually happen either for some people or for all people? [[User:Dúthomhas|Dúthomhas]] ([[User talk:Dúthomhas|talk]]) 23:06, 2 April 2026 (UTC)

I can't work out what Modem mode is meant to do... on my machine it just freezes the whole page. [[Special:Contributions/78.213.151.110|78.213.151.110]] 20:22, 1 April 2026 (UTC)
:It plays the sound of an old-style phone modem, and scrolls the comic into view slowly. It's supposed to represent the early days when downloading an image would take a long time. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 20:31, 1 April 2026 (UTC)
:can confirm on android firefox it seems to render the page unresponsive to input - [[User:Vaedez|Vaedez]] ([[User talk:Vaedez|talk]]) 21:18, 1 April 2026 (UTC)
:Same here on Desktop Firefox - under "Modem mode", the whole page freezes up and the browser prompts me to close it ("this page is slowing down Firefox", or words to that effect). I wonder if it's a Firefox thing - odd if so, because I imagine Randall of all people would test on browsers other than Chrom* - or some weird side-effect of my ad/popup/script/cookie-blockers. A shame because all the other modes seem to work - "Greyscale mode" is far too subtle, and I'm ashamed to admit I missed the change from "math" to "maths"! - but this is a great April Fools' comic.

:Firefoxer here, and ''without'' any particular add-ons that might interact badly with it... It does (seem to) lock up and it does (sometimes... didn't on at least one occasion) prompt Firefox to ask if I want to stop the page. But if I wait long enough it 'wipes off' the last seen comic image, starts to 'scanline' it back (note: not actually accurate to the real days of modems, as you'd probably be loading up images in interlaced mode) and ''then'' starts to give a modem-shriek.
:I wonder, without delving into the code used, if it's the method used to 'sleep' (could it be using busy-busy NOP-like code, rather than true sleep-interupts?), or just a slightly different asynchronous script-handling method that Firefox uses instead of other test-platforms.

: For me (in Chrome) it scrolled the whole page in from the bottom, but then kept scrolling so that you got the top of the page appearing beneath the bottom of it - like a TV with vertical hold problems (kids - ask your grandparents). Then changing to other modes it was stuck in that position. However, on subsequent attempts it only scrolled open the comic portion of the page.

I see the mobile site m.xkcd.com was left out on this change😔 [[Special:Contributions/104.28.215.219|104.28.215.219]] 20:37, 1 April 2026 (UTC)
:I have been viewing via a tablet, though I think I've permwnently set my browsers to ''not'' use mobile version sites (they tend to assume viewing everything in portrait, I have found, whereas I almost always browse in landscape, so it gives me badly relocated on-page menu bars, or other wierdnesses).
:Everything seems to work nicely, as I bounced back and forth between modes (and occasionaly went to other comics to see how something like Stained Glass worked with them). Until I tried out the Star Wars scrolling one. Earlier on, I'd checked it out on a desktop, so I left it until one of the last few because it was hardest on the desktop to move on from (unless you used the cursor key, when you'd let the select-drop-down element drift to far 'away' to easily click.
:However, on the tablet, it ''just'' goes black, no appearance of the scrolly-scrawled page contents. (No way to use cursors to change the in-focus drop-down element to a neighbour.) Back-paging just takes me back through the various Random-comic pages I'd passed through, then the plain xkcd.com latest-comic default, all completely black, no animation. (Plane/Boat/Spring/Screensave mode dynamics, etc animated/transformed properly in their various ways.) Back-paging to before landing on xkcd.com (the tab I'd set off from) then forward again landed me in the all-black page with no space-sprawl in evidence...
:...''until'' I turned the tablet sideways (portrait proportions), and there it was. And rotated back to landscape to find it ''still'' properly visible, still scrolling away. Also, discovered I could drag (without pinch-dragging, which is zooming) the scrawl back 'towards me' (essentially scrolling down the skewed page, not an interaction that I'd attempted on the desktop computer), so that I could intercept the dropdown box and shift myself onto a different mode again.
:This is on Chrome For Android. I have other tablet browsers handy, but would need to check them properly before committing to ''their'' compatabilities or peculiarities. But sort of works, after you get over a funny hurdle (as just described), and ''perhaps'' need to have set Desktop Site as default rather than letting your device attempt to automatically use the "m." site version.

I read “Modern mode” instead of Modem mode and I spent a while making wild theories about what it could be referencing. But I’m also quite sleepy. [[Special:Contributions/146.70.116.107|146.70.116.107]] 20:51, 1 April 2026 (UTC)

I deminified the code if anyone wants it. There are no hidden options or anything like right-click has, but it would be extremely easy to add modes to it. [[Special:Contributions/2601:441:4B7E:7660:0:0:0:AC72|2601:441:4B7E:7660:0:0:0:AC72]] 20:59, 1 April 2026 (UTC)

Not gonna lie, I got nerd-sniped hard here. I thought the noise in the modem mode might be real modem noises, and I tried to demodulate it. With Gnuradio, I got to the point of guessing that it's 4FSK at 2400 baud, with a center frequency of about 1700 Hz and a frequency deviation of about 300 Hz. I couldn't find the corresponding modem standard, so I started deminifying the source code that generates it. The good news is that I was correct. It's 4FSK, 2400 baud, center frequency 1710 Hz, frequency deviation 270 Hz. The bad news? The data is Math.random(). That feels bittersweet. I saw a puzzle where there was none. I want to post the relevant snippet of deminified code. Am I allowed to do that? Is the site itself also under CC-BY-NC, or just the comics?

Honestly, I'd love a real dark mode for xkcd.com. But one where the comic isn't inverted. Sometimes I prefer to read the comic here on explainxkcd.com since I have mediawiki settings for dark mode, but those don't invert the comic. (I don't think I can make mediawiki settings for space opera mode...) [[User:Orion205|Orion205]] ([[User talk:Orion205|talk]]) 00:28, 2 April 2026 (UTC)
:You should be able to force a custom CSS on this site (with or without any browser-helpers, but there are ones out there that streamline/automate/augment this ability). The AFD-code is applying a full visual filter (over the top of the comic; maybe or maybe not above the mode-selection 'widget', depending upon browser implementation), but sounds like you just want to apply foreground/background inversion as priority (above anything xkcd.com normally 'suggests' via CSS/tag-attributes) to all markup, but leave the comic image (and any other images, like the thumbnails) as is. Might he tricky if any element is "black-on-transparency" image, which assumes white but now has your code turning it black behind the non-transparent black, but you could probably live with it (or make it 75% dark-grey or so?), and non-transparent black-on-white (presuming white all around it) could look strange.
:But you can't tell for sure without trying to tweak your end (or actually checking the source HTML, on the way to doing just that).
:Alternatively, maybe you can isolate the on-site code for just the Dark Mode of the entire-page treatment, modified to 'demask' the filter exactly over the limits of the comic img-rendering area. If it's been done the way I think it's been done (not gonna try to check, 'til I'm not on mobile platform myself) should be a fairly trivial job to add to the fraction of the code you 'borrow'. Or at least a learning experience, as you work out what tweaks do what. [[Special:Contributions/82.132.237.40|82.132.237.40]] 12:22, 2 April 2026 (UTC)

:fyi ive found that the comic panels bounce on the edges of the viewport but move with reference to page coordinates--which means if you scroll just right you can place a corner of your screen where it's going to hit, without having to wait for it to get there on its own - [[User:Vaedez|Vaedez]] ([[User talk:Vaedez|talk]]) 03:39, 2 April 2026 (UTC)

I wonder if the choice of the actual text in the comic is a reference to the Apollo 8 Christmas broadcast of Genesis, due to the Artemis II launch today... or maybe I'm overthinking it and it's simply a joke about light and dark mode.

The current explanation of dark mode as 'inverting black and white pixels' isn't quite correct. For example, on [[2623]] a pale yellow colour gets flipped to black. On the other hand, other colours elsewhere are left untouched. So it must be doing 'some very light area of colour palette > black' and presumably 'some very dark area of colour palette > white'.

: Writing a script to solve Minesweeper is a great exercise and helps to build a guaranteed-solvable game (which, IMO, is a good thing), but it won't usually start with image recognition. I'm not sure how hard it would be to write an image solver, especially if - unlike in this example - you'd need to dig some cells to finish solving it. [[Special:Contributions/108.162.250.59|108.162.250.59]] 16:20, 30 July 2021 (UTC)

I think that it would be better to explain why there is mine in B3 and D3 (due to the ones) because you then have the full solution. I think that the curent explanation isn't complete enough for someone who don't know minesweeper to understand the solution
Maybe it is only me but I think that it would be less confusing to have column marked with letter and line with number. i don't know if there is any standard for that. I am used to excel way of doing it [[Special:Contributions/162.158.50.27|162.158.50.27]] 16:10, 30 July 2021 (UTC)

:As a native German speaker I do not think the title sounds similar. The German Mein is a bit more open than the English Mine which is spoken a bit longer.

I think that explanation misses the fact that images in captcha are in randomized order and do not match with actual position on real board and are actually, which can be deducted from fact it's using different colors and font, from multiple separate games. Therefore 'solving' it gives no actual information.
[[User:Kalumniatoris|Kalumniatoris]] ([[User talk:Kalumniatoris|talk]]) 20:39, 30 July 2021 (UTC)

Using the Excel numbering, here’s one verbose way of solving it:
If someone is confused, it may be helpful to draw a diagram and follow along, step by step.

Fact 1: C1 indicates that 1 of its 4 open neighbors is a mine.
Fact 2: A1 indicates that 2 of its 3 open neighbors are mines.
Conclusion 1: Looking at B1 and B2, Fact 1 says at most 1 is a mine and Fact 2 says at least 1 is a mine. Therefore exactly 1 is a mine.
Conclusion 2: Looking at the three open cells around A1, we now know from Conclusion 1 that B1 and B2 account for exactly one mine next to A1, so the other mine adjacent to A1 must be in A2.
Conclusion 3: Looking at C1, from Conclusion 1 we know that B1 and B2 account for the 1 mine next to C1, so there can be no mine in D1 or D2.

Fact 3: A3 indicates that 3 of its 4 originally open neighbors are mines.
Fact 4: B4 indicates that 1 of its 4 open neighbors is a mine.
Conclusion 4: Looking at A4 and B3, Fact 3 indicates that at most 1 is empty (or equivalently, that at least one is a mine) and Fact 4 indicates that at most one is a mine. Since these two contain at least 1 mine and at most 1 mine, they must contain exactly 1 mine.
Conclusion 5: Looking at Fact 4, we know that A4 and B3 account for the 1 mine adjacent to B4, so C3 and C4 must be empty.

Fact 5: D4 indicates that 1 of the 3 originally open neighbors must be a mine.
Conclusion 6: Looking at fact 5, we see that Conclusion 5 ruled out 2 of the 3 neighbors, so D3 must be the mine.

(We’ve now determined the state of all cells in columns C and D, as well as A2. We’ve also identified two pairs (B1+B2 and A4+B3) that each contain exactly one mine.)

Fact 6: C2 indicates that exactly 3 of its 5 originally empty neighbors contain mines.
Conclusion 7: From Conclusion 1 we know that exactly 1 of B1 and B2 is a mine, from Conclusion we know C3 is empty, and from Conclusion 6 D3 is a mine. Having accounted for 4 of the 5 neighbors, and 2 of 3 mines, we know that the remaining cell, B3, must be a mine.
Conclusion 8: Based on Conclusion 5 and Fact 3, we can see that exactly one of A4+B3 is a mine and therefore the other two cells adjacent to A3 must account for its other two mines. Therefore B2 is a mine.

I don't think it's that relevant that the captcha-solver shall click on the mines, opposite to the standard game. (The problem obviously is that if you were supposed to click on non-mines, you might simply click the number fields.

I guess no one thought to mention that it is possible to have technically unsolvable (by logic) minesweeper puzzle boards, either when there is a very high, or very low, concentration, usually at an edge or a corner. I was kinda disappointed that he didn't do that and make it interactive so that the (usually) 50/50 choice always came out wrong, or you had to trick it by clicking down on one (internally making it the mine) and releasing on the other (revealing the now safe square)... or maybe I'm just a sadist >.> [[Special:Contributions/172.69.63.143|172.69.63.143]] 09:12, 31 July 2021 (UTC)

I do not work for this game, I just play it: If you really dig the difficult logic required to solve this minesweeper puzzle, check out Fill-a-Pix. It's essentially huge puzzles exactly like this. There are many avenues of solving this puzzle. 3@A3 & 1@B4 for example, require that A2&B2 both be mines. 1@C1,3@C2,1@B4,and 1@D4 all collectively require that B3 and D3 are mines. C1 & C2 require that there are 2 mines within the 3 cells: B3,C3,D3. The 1's at B4 and D4 force C3 to be empty, and thus B3 and D3 are the only places those 2 mines could be.

What if what's being signed up for is a messageboard for robots, and it is a reverse CAPTCHA; It only lets robots through (although a much better method of allowing only robots is to ask them to factor something like 702923316547 (the factors are 758141 and 927167)). --[[Special:Contributions/172.70.126.68|172.70.126.68]] 01:38, 2 August 2021 (UTC)

My working method:
* A3's 3 and B4's 1 mean A4 & B3 are mutually exclusively mined, forcing confirmation of A2,B2 as the other two definite mines around A3 and excluding C3&4 as alternate mined neighbours to B4.
* This immediately fulfills A1's 2 and C1's 1; the latter of which, in turn proves D1&2 are unmined.
* D4 can only refer to D3.
* C2 is only fulfilled by confirming A3 (nailing B4's ambiguity in the process).
* Done..?
...I'm surprised it's so simple (excluding errors in putting my thoughts down), even for a 4x4, and expected a tricky logic-chain before some initial assumption was confirmed by an "if..., then if..., then if..., but only if the first assumption was right" chain of some kind (e.g. a soft-commit to one or other of A4/B3, which only resolves, or not, after following the repurcusions half way round the rest of the board and back again - which is how I might need to solve a numeric Kakuro (sp?) puzzle, only I actually send both/''all'' soft possibilities around the relevent parts of the puzzle at the same time if I have to do that. Still, it entertained me to unwrap it my own way. [[Special:Contributions/162.158.159.130|162.158.159.130]] 12:20, 2 August 2021 (UTC)

There are some Minesweeper sites that have a no-guessing mode, which is the only way I like to play since discovering it. Here's one: https://minesweeper.online/game/2111023635. Also, here's a couple logic puzzles with a similar idea: https://www.puzzle-minesweeper.com/mosaic-5x5-easy/ [[User:Blerp|Blerp]] ([[User talk:Blerp|talk]])

Came across this today, and have a few thoughts:
1. The instructions say to click “pictures of mines” — there are ''no mines pictured'' in this puzzle.
2. The (very long) explanation does not make note of the fact that a good number of minesweeper fields ''are not solvable'' from just the presented information.

: Scratches on the DATA layer of any optical disk destroys that DATA. There is also the consideration that the plastics of the majority of optical disks degrade with time and heat. There are some optical media that are designed to prevent such scratching or corruption like the commercially available M-Disk or laser etching into a micro format into a crystal like a 5D disk. Even then the DATA stored must be in an ISO format to read as well as the equipment to read the media needs to be maintained. I have often told people that their data is never safe unless there is a constant effort to copy, check for quality, and make multiple backups using multiple modern mediums as often as humanly possible. All form of digital media can fail, even the extended warranty on a high end HDD will not cover the data lost and most EULAs for cloud storage will say the same.

::Pressed commercial CD-ROMs carry their information between two 0.6 mm thick plastic discs which are glued together, which makes them pretty resilient against scratches on either side – just remove some material with abrasive methods like toothpaste. Often the glue is the bigger issue with low-quality pressings in the long run. This is in contrast to recordable CDs, which are coated with the reflective layer on top of a single disc. –[[User:TisTheAlmondTavern|TisTheAlmondTavern]] ([[User talk:TisTheAlmondTavern|talk]]) 12:24, 31 October 2017 (UTC)

::: CD-ROMS *always* carry their information directly below the reflective layer on the "printed" side of the 1.2mm disk (so around 0.1mm below the print). That's necessary because otherwise the laser would not correctly focus on the data. The recordable CDs have the problem that the reflective layer may not be 100% air resistent and so oxydise the data layer, which is a dye. It's DVDs that have two 0.6mm disks, so in theory you cold flip the DVDs like an LP and use both sides - but then you don't have a surface to print information on it (except the few square cm just around the hole). BlueRay Disks inverted the CD: now the data layer is behind a 0.1mm "thick" coating on the data side. -- [[Special:Contributions/162.158.88.74|162.158.88.74]] 11:23, 8 November 2017 (UTC)

Nothing lasts forever (or at least that's what seems to be true for anything observed by humanity). Data becomes corrupted and lost over time and usage, and books become damaged and lost over time and usage. Not to mention, thousands of books were burned during the Nazi regime. Human minds are inevitably subject to corrupted memories as well. We lose information all the time, and we try to recover what remains. However, it is also worth mentioning that our digital technology is still pretty young compared to books and other sources of information. Information used to be recorded on papyrus, tablets (I understand that this contradicts my point as some tablets have stood the test of time), etc. Some of the earliest Chinese inks were created with soot and animal glue. The first (attempts of) photographs required hours of light exposure and would fade away quickly. Over time, we discovered ways to improve upon these sources of information. The same could apply to our digital information today. We are essentially in the "papyrus" phase of electronic technology (one could argue with other descriptions, but this isn't significant to my statements). In time, we may achieve more successful long-term solutions to maintaining original data. There are so many avenues for the advancement of technology, and those avenues continue to multiply with each step. At this time, we just need to continue to work on our projects and experiments for the progress of humanity. [[User:NAE|NAE]] ([[User talk:NAE|talk]]) 14:29, 31 October 2017 (UTC)

:I think you're kind of right, but it's a weird situation. Disjunction elimination does not require LEM. I can imagine that we have established some list of ''n'' "possibilities" ''p''0, ''p''1, ..., ''p''''n''. What does it mean that these are the only possibilities? Naturally, it means ''p''0 ∨ ''p''1 ∨ · · · ∨ ''p''''n''. Now, if we eliminate all but the ''k''th possibility, that means we have ¬''p''0, ¬''p''1, ..., ¬''p''''k''-1, ¬''p''''k''+1, ..., ¬''p''''n''. By repeated use of disjunction elimination, this proves ''p''''k'' intuitionistically, so the ''k''th possibility ("whatever remains") is provable ("must be the truth"). The problem with this approach is proving the original disjunction. How did we show to begin with that one of those ''n'' possibilities must hold? To do that intuitionistically requires actually proving one of those statements to begin with. And since only one of them is true, we must have already proved ''p''''k'', rendering this argument pointless. Still, it technically is valid.

Dúthomhas: Nah, the reading is consistent with Holmes’s assertion

I’ve found that when looking for an item, I’ll search harder and more thoroughly in the places where the item is supposed to be, which is just frustrating and usually unsuccessful.
Then I realized that if the item isn’t where it’s supposed to be, then it’s somewhere ''it isn’t supposed to be'' - so I start looking in those places.

:I think you're kind of right, but it's a weird situation. Disjunction elimination does not require LEM. I can imagine that we have established some list of ''n'' "possibilities" ''p''0, ''p''1, ..., ''p''''n''. What does it mean that these are the only possibilities? Naturally, it means ''p''0 ∨ ''p''1 ∨ · · · ∨ ''p''''n''. Now, if we eliminate all but the ''k''th possibility, that means we have ¬''p''0, ¬''p''1, ..., ¬''p''''k''-1, ¬''p''''k''+1, ..., ¬''p''''n''. By repeated use of disjunction elimination, this proves ''p''''k'' intuitionistically, so the ''k''th possibility ("whatever remains") is provable ("must be the truth"). The problem with this approach is proving the original disjunction. How did we show to begin with that one of those ''n'' possibilities must hold? To do that intuitionistically requires actually proving one of those statements to begin with. And since only one of them is true, we must have already proved ''p''''k'', rendering this argument pointless. Still, it technically is valid.

::I originally interpreted it as taking the collection of all (relevant?) propositions, excising the false ones, and deducing that anything that was not excised must be true.

Sorry, I know this has got nothing to do with explaining the above comic, but when I read the title text a thought struck me: if the cat is getting cuter and cuter as it shrinks, a cat lover will get happier and happier as it increases in cuteness. However there will be a point that the cat lover will become sadder as they realise that the cat is going to disappear from their view forever.

i added important fact --[[Special:Contributions/172.69.79.164|172.69.79.164]] 09:13, 20 February 2024 (UTC)
:'u' added extra info (which I had to actually go looking for {{w|Yandere Simulator#Grooming allegations against YandereDev|possible justification}}), but it had nothing to do with the quote being explained. If this guy said "Woooah, ....", and you'd rather he not be mentioned because of another aspect of his life is beyond the pale, then find someone else ({{w|Bill & Ted|like?}} {{w|Shaggy Rogers|or?}}) who might be a more likable example. Or at least link the fact, so that it doesn't look so contextless to the mention.
:But it isn't important in that, even if Randall was obliquely quoting that exact one person, in 2017 he couldn't (and likely wouldn't, if he could) have been referencing the actions/allegations which weren't a thing until years later.

Dúthomhas: an 'iota' is the smallest considerable amount

I'm wondering whether this could be a joke about autocorrect/suggested completion as found in smartphone texting apps.

According to Wikipedia Will Wheaton is not from Washington [[Special:Contributions/162.158.133.150|162.158.133.150]] 08:56, 2 December 2016 (UTC)
:He is most famously (that is, to pen-and-paper rpg gamers as well as those young enough not to have watched TNG and old enough to have watched The Big Bang Theory) a player, fan, and long-time celebrity face of D&D, a tabletop roleplaying game presently made by Wizards of the Coast, who ARE based in Washington; the Seattle coast is "The Coast" the name refers to. That's the immediate reference I got, but I'm nervous enough about adding this note that I'm not sure I should go editing the article itself.

I think the starting point is the ambiguity of the standard "Name all 50 states" challenge. I'm no native speaker but "Name" means both "invent a new name" and "give the correct name for", and Randall is misunderstanding this on purpose. Maybe that's obvious to some, but it seems the sort of thing worth explaining here?--[[User:Blaisorblade|Blaisorblade]] ([[User talk:Blaisorblade|talk]]) 09:02, 2 December 2016 (UTC)
:Clever! That's certainly true, it could be a pun on the word "name". Although Randall has done similar things in the past (putting objects in states, reordering states, drawing physically cumbersome bicycles) that suggest he likes playing with the idea that people who ''sort of'' know how things work but ultimately end up mixing things up and creating something that's not all that accurate (but nonetheless very interesting and creative).

"Colocated" is technically misspelled (it's either "co-located" or "collocated"), though that could be for the sake of matching it to "Colorado." However, the word is used in many situations other than "co-location center" (e.g. workers being collocated in the same office), so unless Colorado is particularly notable for its co-location centers, I don't think it makes sense to claim that that's what it's specifically referring to. –[[User:PhantomLimbic|PhantomLimbic]] ([[User talk:PhantomLimbic|talk]]) 09:36, 2 December 2016 (UTC)
:Hmm, it looks like "colocated" is a spelling used specifically within the industry, so perhaps the claim is warranted after all. –[[User:PhantomLimbic|PhantomLimbic]] ([[User talk:PhantomLimbic|talk]]) 09:50, 2 December 2016 (UTC)

:Collocate is not a synonym for co-locate; [https://www.merriam-webster.com/dictionary/collocate collocate] (pronounced like "kallocate") has the sense of juxtaposing things with each other, especially placing them side by side. This is subtly different from co-locate (housing them in the same location). "Colocate" is an industry [http://www.nytimes.com/2007/10/07/weekinreview/07mcgrath.html shortening] of "co-locate", not a misspelling of "collocate".

Dear, it's old to complain of xkcd's various quality drops, but I think this is my turn. A good number of recent comics have just been variously exaggerated text lists of stuff.

The explanation for "More Dakota" says that "More Dakka" (which I believe to be referenced here) is possibly too obscure to be a shoutout here, as XKCD does not usually mention Warhammer 40,000. However, there is a TV Trope named "More Dakka", and it is well-established that Randall is an avid reader of TV Tropes. (This is also the only way I know about "More Dakka".)

I've taken the liberty to make a description list out of the table (and sort it alphabetically), so it is easier to read on small screens.

Changed the explanation for 'Iota'. An ''iota'' is not an ''in''-considerable amount, but the ''smallest possible'' amount, so named because ''iota'' is the smallest letter in the Greek alphabet (''Ι'' or ''ι''). Hence, when people say, for example, “not one iota of evidence” they are saying the equivalent of “not one shred of evidence” — that is, there isn’t even the smallest piece of evidence.

1767: US State Names

2025-03-29T08:33:18Z

Dúthomhas: /* Explanation */

{{comic
| number = 1767
| date = December 2, 2016
| title = US State Names
| image = us_state_names.png
| titletext = Technically DC isn't a state, but no one is too pedantic about it because they don't want to disturb the snakes.
}}

==Explanation==
[[Randall]] has taken a {{w|map}} of {{w|the United States of America}} labeled "Geography Challenge: Name all 50 States" and filled in the states with words that sound similar to the states' names. The joke is that Randall is apparently terrible at remembering states by heart, or else that he interpreted "name" as "give a name to" and is giving each state a name similar to but different from its previous name. A similar joke is also seen in [[1554: Spice Girls]]. Songs such as the [https://www.youtube.com/results?search_query=fifty+nifty+united+states+song 50 Nifty United States] make these issues seem rarer, thus making it funnier. Below is the list.

This also may be a play on the ambiguity of the phrase "Name all 50 states". When you are asked to "name" something, it can be a request to supply its given name or to come up with a new name for it. Randall has apparently taken the latter interpretation. He also may be playing with the distinction between an object's identity and its label, e.g., "The state of Texas (identity) is named Hexxus (label)", though you can argue that "Texas" is also a label.

This comic is similar to [[1759: British Map]]. Also note that the text at the top of the comic is not in all caps.

===List of States===
Below are the Randall's fictional state names, next to the actual ones in parenthesis, and a short explanation for each one.

; Alberta ({{w|Alaska}})
: {{w|Alberta}} is a Canadian province known for being parochial, politically conservative, and having a strong independence movement, similarly to Alaska.
; Arkanoids ({{w|Arkansas}})
: {{w|Arkanoid}} is an arcade game, developed by Taito in 1986.
; Bandana ({{w|Alabama}})
: A {{w|Kerchief|bandana}} is a large handkerchief cloth, worn either around the head or neck. Often used in Westerns.
; Cafeteria ({{w|California}})
: A {{w|cafeteria}} is both a kind of restaurant and a name for a lunch room that serves food. California is large and diverse, offering a wide variety of choices. California also grows a large proportion of common vegetables available in the US ([http://www.slate.com/articles/health_and_science/explainer/2013/07/california_grows_all_of_our_fruits_and_vegetables_what_would_we_eat_without.html Source]), making it a 'Cafeteria' for the country.
; Candice ({{w|Kansas}})
: {{w|Candice}} is an alternate spelling of the girl's name "{{w|Candace_(given name)|Candace}}", which comes from the Latinized version of "{{w|kandake}}," a title used in the {{w|Kingdom of Kush}} (an ancient African monarchy) for a reigning queen, queen consort, or queen mother; possibly used for female members of the royal family in general.
; Colocated ({{w|Colorado}})
: May refer to computer servers located in a {{w|colocation centre}}, or to {{w|collocation}}, a linguistic term for words or terms that appear together with a frequency greater than chance.
; Connectfour ({{w|Connecticut}})
: {{w|Connect Four}} is a two-player game, in which the objective is to connect four of your checkers in a row while preventing your opponent from doing the same. It has already been mentioned in [[1002: Game AIs]].
; Dakota ({{w|South Dakota}})
: Setting up the joke in North Dakota.
; Delorean ({{w|Delaware}})
: The {{w|DeLorean_DMC-12|DeLorean DMC-12}} is a car, made famous as the {{w|DeLorean_time_machine|time machine}} in the {{w|Back to the Future}} movies.
; District of Colubrids ({{w|District of Columbia}})
: The {{w|Colubridae}} are the biggest family of snakes, accounting for about two thirds of the world's species. As the title text mentions, the District of Columbia, although not part of any state, is technically not a state itself, but is usually labeled on the maps like the 50 others for practical reasons. Here, Randall humorously explains the reason as people not wanting to upset the aforementioned snakes by dismissing their district for this pedantic reason.
; Fallout New Vegas ({{w|Nevada}})
: {{w|Fallout New Vegas}} is a video game set in post-apocalyptic Nevada.
; Fyoridor ({{w|Florida}})
: Possibly derived from the Russian name Fyodor, as in {{w|Fyodor Dostoyevsky}}.
; George ({{w|Georgia}})
: Georgia was named for {{w|George II of Great Britain}}.
; Hexxus ({{w|Texas}})
: The antagonist of {{w|FernGully:_The_Last_Rainforest|FernGully}}. Ferngully is said to be the model for the later film {{w|Avatar_(2009_film)|Avatar}}. This is the second time Hexxus was mentioned in xkcd, the first occurrence being in [[1750: Life Goals]] and the third being in [[1918: NEXUS]]. May allude to the Texas oil industry and the state's general reputation for a lack of environmental protection.
; Idolatry ({{w|Idaho}})
: {{w|Idolatry}} is the worship of a physical object as a god, forbidden in the Abrahamic religions.
; Iota ({{w|Iowa}})
: {{w|Iota}} is the [https://en.wikipedia.org/wiki/Iota ninth letter of the Greek alphabet]. In English, the word [https://en.wiktionary.org/wiki/iota#English iota] may also mean "the ''smallest'' considerable amount".
; Kawaii ({{w|Hawaii}})
: A {{w|Kawaii|Japanese term}} for cute, commonly romanized similar to Hawaii. Not to be confused with {{w|Kauai}}, a Hawaiian island.
; Kennedy ({{w|Kentucky}})
: {{w|Kennedy Fried Chicken}} is a New York City–based fast food brand that shares its initials with KFC, which was formerly (and still conventionally) Kentucky Fried Chicken. "Kennedy" is also the name of a former US president ({{w|John_F._Kennedy|John}}) and two former US senators ({{w|Robert_F._Kennedy|Robert}} and {{w|Ted_Kennedy|Ted}}).
; Louisa ({{w|Louisiana}})
: Louisa, feminine of Louis, is an Old German name meaning "famous warrior". Louisiana was named after King Louis XIV when it was founded as a French colony.
; Masseuses ({{w|Massachusetts}})
: Women who give {{w|massage}}s professionally. A contentious term in the therapeutic massage industry due to its appropriation by prostitutes. Randall might be making fun about how difficult he thinks it is to spell Massachusetts.
; Maybelline ({{w|Maryland}})
: {{w|Maybelline}} is a make-up brand.
; Minestrone ({{w|Minnesota}})
: {{w|Minestrone}} is a thick vegetable soup, originating in Italy.
; Mishy ({{w|Michigan}})
: According to the Urban Dictionary, "mishy" means "[http://www.urbandictionary.com/define.php?term=Mishy mushy and horny at the same time]". Or it could just be a nickname, the way a lot of people's names, often children, get shortened with a trailing y (Bobby, Becky, Johnny, Suzy, Davey, Jimmy, etc.).
; Misstate ({{w|Mississippi}})
: The word "misstate" means to state improperly. "Mis-" is also a prefix meaning "wrong," "incorrect," or simply negating. "Misstate" could be a non-state. {{w|Mississippi State University|Miss State}} is a university in Mississippi. This may also be a joke on the fact that Mississippi is one of the most commonly misspelled state names.
; More Dakota ({{w|North Dakota}})
: Might be a reference to [http://knowyourmeme.com/memes/more-dakka "More Dakka"], a catchphrase by Orks from the {{w|Warhammer_40,000|Warhammer 40000}} universe which is also a page on {{tvtropes|MoreDakka|TVTropes}} referring to the large-scale use of ammunition. May also allude to the idea that North Dakota is less visible in popular culture than its Southern neighbor, owing to the fact that the latter contains Mount Rushmore but the former does not have any major landmarks.
; mount -a ({{w|Montana}})
: A command to {{w|Mount (computing)|mount}} all disk volumes in fstab (except for ones with the noauto flag).
; Mossouri ({{w|Missouri}})
: The single different letter represents probably a typo (O is adjacent to I in a keyboard). This typo has about 22,000 results on Google. Alternatively, this could be an attempt to "correct" the spelling of the state name to match its non-intuitive {{w|List_of_U.S._state_abbreviations|postal abbreviation}}, MO, which is sometimes used as a pronounceable acronym. Or it could be a reference to [https://en.wikipedia.org/wiki/Katie_Moussouris Katie Mossouris].
; Namaste ({{w|New Mexico}})
: {{w|Namaste}} is a Hindu greeting. Probably unabbreviated from NM (postal code for New Mexico).
; Nebrunswick ({{w|Nebraska}})
: {{w|New Brunswick}}, a Canadian province. New Brunswick is abbreviated "NB" in the {{w|Canadian_postal_abbreviations_for_provinces_and_territories|Canadian postal system}}, and "NB" was also as the postal abbreviation for Nebraska until 1969. It was then changed to "NE" specifically to avoid the confusion between the two. Nevertheless, people sometimes still use "NB" to refer to Nebraska.
; New Hamper ({{w|New Hampshire}})
: A {{w|hamper}} is a large basket, often with lid, used for laundry. Also another name for a picnic basket.
; Newark ({{w|New York (state)|New York}})
: The city of {{w|Newark,_New_Jersey|Newark}} is a suburb of {{w|New York City}} (NYC), and many people who live in Newark commute the 14 miles to work in NYC, however it is actually located in the state of New Jersey rather than New York. Other references: {{w|Newark Liberty International Airport}} (a major flight hub serving the {{w|New York metropolitan area}}), the village of Newark, New York (near Lake Ontario), and {{w|Newark_element14|Newark element14}} (or simply "Newark"), the official distributor of Raspberry Pi. Possible reference to William Gibson's works. A mispronunciation of New York.
; Nude Juggalos ({{w|New Jersey}})
: {{w|Juggalo}} is a name given to fans of the group Insane Clown Posse or any other Psychopathic Records hip hop group. Also shares the same initials as New Jersey.
; Oh Hi ({{w|Ohio}})
: Oh (expression of surprise), Hi (greeting). A common utterance upon meeting an acquaintance unexpectedly.
; Okay ({{w|Oklahoma}})
: OK is the {{w|List_of_U.S._state_abbreviations|state's abbreviation}}. Okay is a spelling of another abbreviation OK, which means "yes" or "good", and has {{w|OK#Proposed etymologies|quite a few possible origins}}. There's also a town in Oklahoma called Okay.
; Organs ({{w|Oregon}})
: Could refer to either {{w|Organ (anatomy)|body parts}} that perform vital functions, or large {{w|Organ (music)|musical instruments}} having rows of tuned pipes. Also a possible reference to {{w|Organ Trail}}, a retro survival video game that parodies {{w|The Oregon Trail (video game)|The Oregon Trail}}.
; Pencilmania ({{w|Pennsylvania}})
: [http://www.imdb.com/title/tt0151935/ Pencil Mania] is a 1932 {{w|Tom and Jerry}} cartoon in which they pull out a pencil and proceed to draw figures in the air. Probably joking about how the first part of Pennsylvania sounds like the word "pencil".
; Roald Dahl ({{w|Rhode Island}})
: A {{w|Roald Dahl|British writer}}, famous for child novels such as {{w|Charlie and the Chocolate Factory}}. This name does not actually rhyme well with Rhode Island. Dahl used the Norwegian pronunciation of his name (roo-ahl dahl, rather than ro-ahld dahl), as he had Norwegian parents. Because of how the pronunciation of the name has not been wildly known by readers, Randall may not have been aware of this.
; Sk8rbois ({{w|Illinois}})
: "Skater Boys" or just "Skater Boy" if the '-ois' is pronounced the same as it is in "Illinois". {{w|Sk8er Boi}} is a song by {{w|Avril Lavigne}}.
; South Caroline ({{w|South Carolina}})
: A further reference to {{w|Sweet_Caroline|song 'Sweet Caroline'}} by Neil Diamond, similar to 'Dakota' and 'More Dakota.' Plays on similarity between the names 'Caroline' and 'Carolina'.
; Spanish Maine ({{w|Maine}})
: The {{w|Spanish Main}} was the mainland Spanish colonial possessions around the Gulf of Mexico. Also refers to the surrounding sea, as in the opening of the (children's?) song, "Sailing, sailing, over the bounding main, ...". May also refer to the {{w|USS Maine (ACR-1)}}, which, upon sinking, started the Spanish-American war.
; Sweet Caroline ({{w|North Carolina}})
: A {{w|Sweet_Caroline|song}} by Neil Diamond.
; That Other One ({{w|Indiana}})
: 'That Other One' is something someone might say if they were trying to name all the states from memory, and knew where a state was but not what it was called. Appropriate for Indiana, due to being a state with relatively few distinguishing features.
; Thennessy ({{w|Tennessee}})
: {{w|Hennessy}} is a brand of cognac.
; Uhaul ({{w|Utah}})
: {{w|U-Haul}} is a company that rents moving vans which are frequently decorated with scenes from places that most people have never visited.
; Verizona ({{w|Arizona}})
: {{w|Verizon}}, a telecommunications company, has the shared text "Rizon" with Arizona (Ve''rizon'', A''rizon''a).
; Vermouth ({{w|Vermont}})
: {{w|Vermouth}} is an Italian alcoholic beverage.
; Virjayjay ({{w|Virginia}})
: Virginia is similar to {{w|vagina}}. Vajayjay is slang for vagina.
; Wainscot ({{w|Wisconsin}})
: {{w|Panelling#Wainscot_panelling|Wainscot}} is a type of wood {{w|panelling}} covering only the lower half of a wall.
; Wilwheaton ({{w|Washington_State|Washington}})
: {{w|Wil Wheaton}} is an actor and writer, famous for his role as {{w|Wesley Crusher}} on {{w|Star Trek}}.
; Wysiwyg ({{w|Wyoming}})
: Acronym for "{{w|WYSIWYG|what you see is what you get}}". A reference to [[Types of Editors]].
; Wyvern ({{w|West Virginia}})
: A {{w|Wyvern}} is a mythical creature.

[[Randall]] has taken a {{w|map}} of {{w|the United States of America}} labeled "Geography Challenge: Name all 50 States" and filled in the states with words that sound similar to the states' names. The joke is that Randall is apparently terrible at remembering states by heart, or else that he interpreted "name" as "give a name to" and is giving each state a name similar to but different from its previous name. A similar joke is also seen in [[1554: Spice Girls]]. Songs such as the [https://www.youtube.com/results?search_query=fifty+nifty+united+states+song 50 Nifty United States] make these issues seem rarer, thus making it funnier. Below is the list.

This also may be a play on the ambiguity of the phrase "Name all 50 states". When you are asked to "name" something, it can be a request to supply its given name or to come up with a new name for it. Randall has apparently taken the latter interpretation. He also may be playing with the distinction between an object's identity and its label, e.g., "The state of Texas (identity) is named Hexxus (label)", though you can argue that "Texas" is also a label.

This comic is similar to [[1759: British Map]]. Also note that the text at the top of the comic is not in all caps.

===List of States===
Below are the Randall's fictional state names, next to the actual ones in parenthesis, and a short explanation for each one.

; Alberta ({{w|Alaska}})
: {{w|Alberta}} is a Canadian province known for being parochial, politically conservative, and having a strong independence movement, similarly to Alaska.
; Arkanoids ({{w|Arkansas}})
: {{w|Arkanoid}} is an arcade game, developed by Taito in 1986.
; Bandana ({{w|Alabama}})
: A {{w|Kerchief|bandana}} is a large handkerchief cloth, worn either around the head or neck. Often used in Westerns.
; Cafeteria ({{w|California}})
: A {{w|cafeteria}} is both a kind of restaurant and a name for a lunch room that serves food. California is large and diverse, offering a wide variety of choices. California also grows a large proportion of common vegetables available in the US ([http://www.slate.com/articles/health_and_science/explainer/2013/07/california_grows_all_of_our_fruits_and_vegetables_what_would_we_eat_without.html Source]), making it a 'Cafeteria' for the country.
; Candice ({{w|Kansas}})
: {{w|Candice}} is an alternate spelling of the girl's name "{{w|Candace_(given name)|Candace}}", which comes from the Latinized version of "{{w|kandake}}," a title used in the {{w|Kingdom of Kush}} (an ancient African monarchy) for a reigning queen, queen consort, or queen mother; possibly used for female members of the royal family in general.
; Colocated ({{w|Colorado}})
: May refer to computer servers located in a {{w|colocation centre}}, or to {{w|collocation}}, a linguistic term for words or terms that appear together with a frequency greater than chance.
; Connectfour ({{w|Connecticut}})
: {{w|Connect Four}} is a two-player game, in which the objective is to connect four of your checkers in a row while preventing your opponent from doing the same. It has already been mentioned in [[1002: Game AIs]].
; Dakota ({{w|South Dakota}})
: Setting up the joke in North Dakota.
; Delorean ({{w|Delaware}})
: The {{w|DeLorean_DMC-12|DeLorean DMC-12}} is a car, made famous as the {{w|DeLorean_time_machine|time machine}} in the {{w|Back to the Future}} movies.
; District of Colubrids ({{w|District of Columbia}})
: The {{w|Colubridae}} are the biggest family of snakes, accounting for about two thirds of the world's species. As the title text mentions, the District of Columbia, although not part of any state, is technically not a state itself, but is usually labeled on the maps like the 50 others for practical reasons. Here, Randall humorously explains the reason as people not wanting to upset the aforementioned snakes by dismissing their district for this pedantic reason.
; Fallout New Vegas ({{w|Nevada}})
: {{w|Fallout New Vegas}} is a video game set in post-apocalyptic Nevada.
; Fyoridor ({{w|Florida}})
: Possibly derived from the Russian name Fyodor, as in {{w|Fyodor Dostoyevsky}}.
; George ({{w|Georgia}})
: Georgia was named for {{w|George II of Great Britain}}.
; Hexxus ({{w|Texas}})
: The antagonist of {{w|FernGully:_The_Last_Rainforest|FernGully}}. Ferngully is said to be the model for the later film {{w|Avatar_(2009_film)|Avatar}}. This is the second time Hexxus was mentioned in xkcd, the first occurrence being in [[1750: Life Goals]] and the third being in [[1918: NEXUS]]. May allude to the Texas oil industry and the state's general reputation for a lack of environmental protection.
; Idolatry ({{w|Idaho}})
: {{w|Idolatry}} is the worship of a physical object as a god, forbidden in the Abrahamic religions.
; Iota ({{w|Iowa}})
: {{w|Iota}} is the [https://en.wikipedia.org/wiki/Iota ninth letter of the Greek alphabet]. In English, the word [https://en.wiktionary.org/wiki/iota#English iota] may also mean "the _smallest_ considerable amount".
; Kawaii ({{w|Hawaii}})
: A {{w|Kawaii|Japanese term}} for cute, commonly romanized similar to Hawaii. Not to be confused with {{w|Kauai}}, a Hawaiian island.
; Kennedy ({{w|Kentucky}})
: {{w|Kennedy Fried Chicken}} is a New York City–based fast food brand that shares its initials with KFC, which was formerly (and still conventionally) Kentucky Fried Chicken. "Kennedy" is also the name of a former US president ({{w|John_F._Kennedy|John}}) and two former US senators ({{w|Robert_F._Kennedy|Robert}} and {{w|Ted_Kennedy|Ted}}).
; Louisa ({{w|Louisiana}})
: Louisa, feminine of Louis, is an Old German name meaning "famous warrior". Louisiana was named after King Louis XIV when it was founded as a French colony.
; Masseuses ({{w|Massachusetts}})
: Women who give {{w|massage}}s professionally. A contentious term in the therapeutic massage industry due to its appropriation by prostitutes. Randall might be making fun about how difficult he thinks it is to spell Massachusetts.
; Maybelline ({{w|Maryland}})
: {{w|Maybelline}} is a make-up brand.
; Minestrone ({{w|Minnesota}})
: {{w|Minestrone}} is a thick vegetable soup, originating in Italy.
; Mishy ({{w|Michigan}})
: According to the Urban Dictionary, "mishy" means "[http://www.urbandictionary.com/define.php?term=Mishy mushy and horny at the same time]". Or it could just be a nickname, the way a lot of people's names, often children, get shortened with a trailing y (Bobby, Becky, Johnny, Suzy, Davey, Jimmy, etc.).
; Misstate ({{w|Mississippi}})
: The word "misstate" means to state improperly. "Mis-" is also a prefix meaning "wrong," "incorrect," or simply negating. "Misstate" could be a non-state. {{w|Mississippi State University|Miss State}} is a university in Mississippi. This may also be a joke on the fact that Mississippi is one of the most commonly misspelled state names.
; More Dakota ({{w|North Dakota}})
: Might be a reference to [http://knowyourmeme.com/memes/more-dakka "More Dakka"], a catchphrase by Orks from the {{w|Warhammer_40,000|Warhammer 40000}} universe which is also a page on {{tvtropes|MoreDakka|TVTropes}} referring to the large-scale use of ammunition. May also allude to the idea that North Dakota is less visible in popular culture than its Southern neighbor, owing to the fact that the latter contains Mount Rushmore but the former does not have any major landmarks.
; mount -a ({{w|Montana}})
: A command to {{w|Mount (computing)|mount}} all disk volumes in fstab (except for ones with the noauto flag).
; Mossouri ({{w|Missouri}})
: The single different letter represents probably a typo (O is adjacent to I in a keyboard). This typo has about 22,000 results on Google. Alternatively, this could be an attempt to "correct" the spelling of the state name to match its non-intuitive {{w|List_of_U.S._state_abbreviations|postal abbreviation}}, MO, which is sometimes used as a pronounceable acronym. Or it could be a reference to [https://en.wikipedia.org/wiki/Katie_Moussouris Katie Mossouris].
; Namaste ({{w|New Mexico}})
: {{w|Namaste}} is a Hindu greeting. Probably unabbreviated from NM (postal code for New Mexico).
; Nebrunswick ({{w|Nebraska}})
: {{w|New Brunswick}}, a Canadian province. New Brunswick is abbreviated "NB" in the {{w|Canadian_postal_abbreviations_for_provinces_and_territories|Canadian postal system}}, and "NB" was also as the postal abbreviation for Nebraska until 1969. It was then changed to "NE" specifically to avoid the confusion between the two. Nevertheless, people sometimes still use "NB" to refer to Nebraska.
; New Hamper ({{w|New Hampshire}})
: A {{w|hamper}} is a large basket, often with lid, used for laundry. Also another name for a picnic basket.
; Newark ({{w|New York (state)|New York}})
: The city of {{w|Newark,_New_Jersey|Newark}} is a suburb of {{w|New York City}} (NYC), and many people who live in Newark commute the 14 miles to work in NYC, however it is actually located in the state of New Jersey rather than New York. Other references: {{w|Newark Liberty International Airport}} (a major flight hub serving the {{w|New York metropolitan area}}), the village of Newark, New York (near Lake Ontario), and {{w|Newark_element14|Newark element14}} (or simply "Newark"), the official distributor of Raspberry Pi. Possible reference to William Gibson's works. A mispronunciation of New York.
; Nude Juggalos ({{w|New Jersey}})
: {{w|Juggalo}} is a name given to fans of the group Insane Clown Posse or any other Psychopathic Records hip hop group. Also shares the same initials as New Jersey.
; Oh Hi ({{w|Ohio}})
: Oh (expression of surprise), Hi (greeting). A common utterance upon meeting an acquaintance unexpectedly.
; Okay ({{w|Oklahoma}})
: OK is the {{w|List_of_U.S._state_abbreviations|state's abbreviation}}. Okay is a spelling of another abbreviation OK, which means "yes" or "good", and has {{w|OK#Proposed etymologies|quite a few possible origins}}. There's also a town in Oklahoma called Okay.
; Organs ({{w|Oregon}})
: Could refer to either {{w|Organ (anatomy)|body parts}} that perform vital functions, or large {{w|Organ (music)|musical instruments}} having rows of tuned pipes. Also a possible reference to {{w|Organ Trail}}, a retro survival video game that parodies {{w|The Oregon Trail (video game)|The Oregon Trail}}.
; Pencilmania ({{w|Pennsylvania}})
: [http://www.imdb.com/title/tt0151935/ Pencil Mania] is a 1932 {{w|Tom and Jerry}} cartoon in which they pull out a pencil and proceed to draw figures in the air. Probably joking about how the first part of Pennsylvania sounds like the word "pencil".
; Roald Dahl ({{w|Rhode Island}})
: A {{w|Roald Dahl|British writer}}, famous for child novels such as {{w|Charlie and the Chocolate Factory}}. This name does not actually rhyme well with Rhode Island. Dahl used the Norwegian pronunciation of his name (roo-ahl dahl, rather than ro-ahld dahl), as he had Norwegian parents. Because of how the pronunciation of the name has not been wildly known by readers, Randall may not have been aware of this.
; Sk8rbois ({{w|Illinois}})
: "Skater Boys" or just "Skater Boy" if the '-ois' is pronounced the same as it is in "Illinois". {{w|Sk8er Boi}} is a song by {{w|Avril Lavigne}}.
; South Caroline ({{w|South Carolina}})
: A further reference to {{w|Sweet_Caroline|song 'Sweet Caroline'}} by Neil Diamond, similar to 'Dakota' and 'More Dakota.' Plays on similarity between the names 'Caroline' and 'Carolina'.
; Spanish Maine ({{w|Maine}})
: The {{w|Spanish Main}} was the mainland Spanish colonial possessions around the Gulf of Mexico. Also refers to the surrounding sea, as in the opening of the (children's?) song, "Sailing, sailing, over the bounding main, ...". May also refer to the {{w|USS Maine (ACR-1)}}, which, upon sinking, started the Spanish-American war.
; Sweet Caroline ({{w|North Carolina}})
: A {{w|Sweet_Caroline|song}} by Neil Diamond.
; That Other One ({{w|Indiana}})
: 'That Other One' is something someone might say if they were trying to name all the states from memory, and knew where a state was but not what it was called. Appropriate for Indiana, due to being a state with relatively few distinguishing features.
; Thennessy ({{w|Tennessee}})
: {{w|Hennessy}} is a brand of cognac.
; Uhaul ({{w|Utah}})
: {{w|U-Haul}} is a company that rents moving vans which are frequently decorated with scenes from places that most people have never visited.
; Verizona ({{w|Arizona}})
: {{w|Verizon}}, a telecommunications company, has the shared text "Rizon" with Arizona (Ve''rizon'', A''rizon''a).
; Vermouth ({{w|Vermont}})
: {{w|Vermouth}} is an Italian alcoholic beverage.
; Virjayjay ({{w|Virginia}})
: Virginia is similar to {{w|vagina}}. Vajayjay is slang for vagina.
; Wainscot ({{w|Wisconsin}})
: {{w|Panelling#Wainscot_panelling|Wainscot}} is a type of wood {{w|panelling}} covering only the lower half of a wall.
; Wilwheaton ({{w|Washington_State|Washington}})
: {{w|Wil Wheaton}} is an actor and writer, famous for his role as {{w|Wesley Crusher}} on {{w|Star Trek}}.
; Wysiwyg ({{w|Wyoming}})
: Acronym for "{{w|WYSIWYG|what you see is what you get}}". A reference to [[Types of Editors]].
; Wyvern ({{w|West Virginia}})
: A {{w|Wyvern}} is a mythical creature.

Talk:1166: Argument

2025-03-28T23:44:52Z

Dúthomhas: Humor?

Anyone know if there really is a thread for this? I Googled the title as shown in quotes and it didn't give me any results. Without quotes gave me the xkcd forums as well as some Creationist stuff. [[Special:Contributions/76.122.5.96|76.122.5.96]] 07:39, 28 January 2013 (UTC)

The explanation for the third post should make note of the situation where you hang a flywheel (e.g. a bicycle wheel) by each end of its axis using cords, spin the wheel then cut one cord, and the bicycle wheel will keep spinning in the same position! There was a YouTube video for this, but I cannot find it, there must be more people who know what I'm talking about.

Can anyone identify the icons at the left of the three postings in the comic? The first looks to be a generic head, but the second is a device of some kind, with (perhaps) a push-button, and a wire leading from and connecting back to the device. The third might be a person standing next to a Tesla coil or Van de Graaff generator. [[User:Vere Nekoninda|Vere Nekoninda]] ([[User talk:Vere Nekoninda|talk]]) 14:42, 31 January 2013 (UTC)

The second device is a power strip plugged into itself. Free energy, after all.

''the total time any perpetual motion machine has been running is 0 seconds''

Pretty sure that, while literally true in the sense that no perpetual motion machine exists and therefore has never run for any length of time, that's not what Randall meant: I'm sure he meant the total time any '''attempted''' perpetual motion machine has run may be in the weeks and months but not the many years since he started the argument. I will edit in 24 hours if nobody objects. [[User:AmbroseChapel|AmbroseChapel]] ([[User talk:AmbroseChapel|talk]]) 00:50, 1 September 2017 (UTC)

Alas for missed opportunities. Remember, the total time any perpetual motion machine has been running is 0 seconds (rounded up).

The delivery of freshly boiling water on to the bag is the major issue with microwaves, not the nucleation thing in my experience. Bear in mind I don't even actually like tea, still care enough to right this, but i'll be signing this anonymously to avoid shame being bought on my family and my family's familys.

"...to the point virtually every home has an electric tea kettle as a standard appliance". If I'm reading it correctly, this and the comic suggests we (though not I, as I'm not a tea-drinker) make tea ''in the electric kettle''. Electric tea-urns, yes, or maybe a setup like a samovar. But, generally, the kettle itself (and, so far as I'm aware, always with an electric kettle) is used to heat the water, which you then pour into the tea''pot'' into which the requisite number of tealeaves/teabags are also put to steep. (Or, for the lazy way, into the mug-with-teabag.) I wouldn't be able to use my electric kettle to (for example) make my instant mashed-potato into the actual mash, if I'd have regularly used it to mash tea. Or top up the boiling saucepan that I'd realised I'd not quite enough water in to cover the pasta/vegetables/whatever. Or to easily add nust a little more heat (with less new water) to the washing-up bowl than would be possible from the hot tap, back to as hot as possible without scalding me. – Whether intentional or not, I suspect Randall has the role of kettle and teapot mixed up, and so (without the intent to parody) has the editor who wrote the above. [[Special:Contributions/172.70.160.135|172.70.160.135]] 05:49, 10 December 2024 (UTC)
:: Agree, we make tea in a mug using water from a kettle. I'd be furious if an American made tea in my kettle, how will I then make up my instant Nescafe? [[User:Kev|Kev]] ([[User talk:Kev|talk]]) 18:28, 10 December 2024 (UTC)

I don't think the section on 'Boiling the water in a pot' refers to a teapot - I think it means boiling the water in a pot on the hob, and then making tea with it (in a pot/mug). [[Special:Contributions/172.69.195.27|172.69.195.27]] 07:53, 10 December 2024 (UTC)
:I agree, but I also think there's a language issue with the use of pot vs. pan that makes things more confusing. I think there are several types of cookware that Americans call pot and British call pan. So British would not say they boil water in a pot but rather in a saucepan (if there's no kettle available of course). [[User:Mtcv|Mtcv]] ([[User talk:Mtcv|talk]]) 09:03, 10 December 2024 (UTC)

I (as Brit) am uncommon in using an electric filter coffee machine to make tea (two bags in what is supposed to be the coffee filter). Set up, press the button and come back to a not jug of fresh tea which is not stewed. If later, the hot plate has shut off and it is cold, you can zap it in a mug in the microwave.

: As another brit, what? I do not understand the mechanics of this, please elaborate. Additionally, my understanding is that the water would be *briefly acquainted* with the tea, thus would be a poor facsimile of "tea" and would rather be closer to something the americans would attempt.

::I'm guessing the water would drip on to the teabags, then soak all the way through them and drip out into the jug, without allowing sufficient to accumulate that it would run straight out without passing fully through the bag.

:::Your guess is right. It works because the (finely cut) leaves are exposed to boiling hot water for a few minutes, you wouldn't drink any before you have half a jug and that is quite 'bright'. Better than a teabag in a mug! Want it stronger, use more bags. Big advantage - you set it up, press button, come back in 5 to 25 minutes and your tea is waiting, including a second mug, not and not stewed. Wrong - but works so right.

You Westerners have literally no idea how to make proper, good tea! SMH [[User:TPS|TPS]] ([[User talk:TPS|talk]]) 13:00, 10 December 2024 (UTC)

As a Brit who grew up in sight of the Yorkshire Tea factory – and worked there on occasion – and having travelled very widely around the world – including in the US – I feel I'm supposed to have an opinion. However, I have ''never'' encountered the microwaving of water as mentioned here, and I would not object to it as supposedly problematic for tea-quality reasons. I'd object for reasons of common sense. What mystifies me is the idea that kettles are tea-specific. They are for heating water, not making tea. Coffee uses hot water. Pasta, rice and potatoes use hot water. Peas, carrots, cabbage, sweetcorn...

Baking bread often involves a pan of steaming water in the oven.

"But I can boil water in a pan for cooking pasta or vegetables."

Yes, but you'll be waiting a l-o-o-o-ng time. I'll heat my water in the kettle, pour it into the now-hot pan, cook my pasta, and I'll be eating before your water is boiling.

A kettle is not a tea-making item any more than a frying pan is an omelette-making item; tea is simply one of the things you can make with water from a kettle. Hot water is a basic civilised human commodity, predating recorded history. That we should live in a mechanised world, and the Consumer Nation doesn't have water-boiling appliances as standard (saying instead "I don't have a kettle because I don't drink tea") is ludicrous.

Using a microwave rather than buying a kettle is a bit like not buying a hammer for driving in nails because you've got a big pair of pliers that will do. Sure, they're heavy lumps of metal than live in your toolbag, but they're not the right thing.

The Brits, incidentally, are not tea lovers. They are prolific consumers of awful tea that actual tea lovers wouldn't use for cleaning their drains. The most enthusiastic tea enthusiasts I've ever met were from Maryland.

It's all just social ceremony in the UK. Milk first, tea first, must use a saucer, must use a pot...tea is a British religion, not a British drink.[[User:Yorkshire Pudding|Yorkshire Pudding]] ([[User talk:Yorkshire Pudding|talk]]) 14:23, 10 December 2024 (UTC)
: How long does it take you to boil water for, let's say enough water for four people's worth of pasta, using an electric kettle? I reckon that's about 4 liters of water? I'm genuinely curious. Now also double the time, because as mentioned in the explanation, American outlets produce half the power of British outlets. And let me not fail to mention that almost all American homes have either special higher power outlets for stoves or gas powered stoves, and frequently have special high-power outlets for microwaves as well. 4 liters of water to boil takes about 5-6 minutes on a low-end American stove, about 3-4 minutes on a gas stove, and about 2 minutes on an induction stove. None of which strikes me as a particularly long time, especially when the most popular varieties of pasta in America all need to be boiled for 8+ minutes. How does this compare to twice the length of time as your electric kettle? Because if your Electric Kettle actually allows you to be eating your pasta before our water has even boiled, that would require your kettle to boil water in around -2min to -6min. And if your electric kettle can time travel, then that is truly an astonishing device. Honestly my takeaway from this is that British Stoves must be apparently heated by a single candle if "boiling water for pasta" is considered to take a "l-o-o-o-ng time". {{unsigned ip|162.158.126.161|21:51, 10 December 2024 (UTC)}}

I wonder what the Brits would feel about repurposing a single-cup coffee maker. These days, I usually put a tea bag in a mug and place it in a Keurig machine and run it (without a K-cup, of course) to deliver the hot water. Probably the wrong temperature, but fast and easy and the result is good enough. [[User:Shamino|Shamino]] ([[User talk:Shamino|talk]]) 14:52, 10 December 2024 (UTC)

Would any British person care to evaluate my tea making practices? Boil water in electric kettle. Pour water over teabag, allow to steep, remove teabag. Add sugar and ice cubes. [[User:RegularSizedGuy|RegularSizedGuy]] ([[User talk:RegularSizedGuy|talk]]) 15:54, 10 December 2024 (UTC)
:...well, seems a fairly standard "making one mug of tea for oneself" process. It lacks a milk-adding stage (thus no arguments about whether before or after the water). Removing the teabag at that point probably means it's not going to become a Builders' Brew, which is your choicd. Sugar is ok. And... Waitwhat... ''Ice Cubes?!?'' ...can I get back to you on that?

I can confirm (by inadvertent experiments conducted on flatmates) that they indeed do not like tea being make in the kettle. What really makes them angry though is making coffee in the teapot. It ruins the taste of the teapot forever apparently. There is also a faction that insists that a teapot should never be washed, and washing it invokes a lesser anger.[[User:Gopher|Gopher]] ([[User talk:Gopher|talk]]) 15:56, 10 December 2024 (UTC)

On rare occasions where I don't have a kettle available, I use a microwave oven to boil water for tea. But it doesn't look and taste quite the same, and often leaves an ugly foam at the surface when the tea bag is added. This phenomenon is investigated here: https://cooking.stackexchange.com/a/22264.

There is a [https://www.tumblr.com/elodieunderglass/669449994039853056/wizardlyghost-silverjirachi-pidoop tumblr thread] about the topic of teamaking in microwaves, kettles, etc. Funnily enough it showed up in my Instagram reels feed just a few hours before this comic was posted. I was thinking perhaps Randall saw it too and was inspired by it? Both of them have to deal with the different ways of making tea and how "absurd" or "unconventional" (etc.) they are.

I'm guessing my occasional summertime practice of filling a gallon jar with water and lots of tea bags, setting it on the back porch in the sun for a few hours until the water turns dark brown, then putting the whole thing in the refrigerator and later drinking it over ice would be toward the more angry end of the spectrum.[[Special:Contributions/172.70.126.204|172.70.126.204]] 16:39, 10 December 2024 (UTC)Pat

There are several comics with unmarked scales. It would be interesting if the descriptions started using pixels to point where each mark is along the line. As a rough estimate, the four points mentioned here are at X-values: 90px, 115px, 345px, and 645px, indicating that the pot method is 10% as infuriating as the chalice method - or that making tea in a pot ten times would be equally as infuriating as making it once in a chalice (at least, assuming the kettle method causes zero furons.

I would argue that the more pessimistic interpretation of the two low-end options makes sense, rather than the more generous versions offered in the current explanation. I think the first one does literally mean making tea in the kettle, and the second one does mean boiling water in a teapot. Making tea *using* a kettle isn't anything to get mad about, it's the default practice. That should put it at the zero point of the line, but it isn't, it's to the right. On the other hand, obviously making tea *in* the kettle would incite a modest amount of rage (on the scale of zero to microwaving a mug), and it makes sense that boiling water in a teapot would incite about 50% more, as shown.[[Special:Contributions/172.69.134.160|172.69.134.160]] 19:51, 10 December 2024 (UTC)
: An American making tea in the correct way by boiling water in the kettle and then pouring that into a teapot with the tea would still probably conspire to make it badly and make the Brit angry.

There is a standard for making tea, ISO 3103: https://en.wikipedia.org/wiki/ISO_3103, and apparently from the Royal Society of Chemistry.

''Ultimately, the real difference comes down to convenience: In the USA, the standard voltage for electric appliances (including an electric kettle) is 120 volts, while it is twice that (240 volts in practice, though nominally 230V) in the UK. Since the amperage for an electric kettle is the the same in both countries (15 amps), this means that an equivalent kettle in the UK has twice the power (3.2kw versus 1.6kw), and can heat the water in a fraction of the time. Meanwhile, a standard microwave has a similar power in both countries (from 700 to 1000 watts), for reasons unrelated to the supply voltage it is equipped to use. Therefore, heating a small cup in a microwave might take a few moments longer than a kettle in the USA, but is many times slower to wait for compared to using an electric kettle in the UK.'' Electric kettles are a bit faster in the UK due to the voltage difference, but it's not that much and I highly doubt speed is the main concern here. The main 'convenience' difference between boiling water in a kettle vs a microwave is quantity: Brits usually don't just make one cup/mug of tea! On the rare occasion Americans drink tea, it's more often just the one person drinking one cup, making a microwave a convenient choice.[[Special:Contributions/162.158.233.90|162.158.233.90]] 21:40, 10 December 2024 (UTC)

It's not about voltage. They use different gauge heater wire to get the Watts wanted/allowed.

The classic UK plug is nominal 13 Amps. (The circuits may be nominal 16A but there is now better insulation than in 1949.) At 230 Volts that would be 3KW (near enuff). That will be the "legal numbers". At 240V it may be 3,250W true. OTOH a 10V sag might be expected in all but the poshest wall-wiring.

amazon.co.uk sells kettles nearly all rated 3KW. Exceptions are Greepas at 1800W ("However, some customers have reported that it's very slow to boil"); also Philips 2200W, Daewoo 1400W, and OLEGA 1500W 'Fast Boiling'.

OTOH!!

On Amazon US site nearly all kettles are 1500W, a few lower like 1100W. At assumed 120V 1500W is 12.5Amps. 15Amp circuits are still common in older houses (despite changes in 1960s) but we supposed to de-rate for 'long-running' (not clearly specified in old code) so 12 Amps is in a ballpark.

Note that all US kettles are lower power than all but the tamest UK kettles. Essentially half power.

And IIRC, the 13/16A rating which allows super-power kettles in the UK was not for tea but for "electric fire", room heat. In post-War rebuilding, smokey coal was already depreciated in cities, steam plumbing and chimneys are expensive. Copper wire is costly too, but you "have" to have electric, and low-cost plans like ring-main were investigated.

"accept that tea-appropriate boiling water can be obtained directly from the sink's plumbing" - unless it comes out literally at boiling temperature, it isn't tea appropriate. I live in France now, and order catering bags of tea from Amazon because French tea is dismally awful, not helped at all by this fairly widespread belief that black tea steeps at 60C.

}}

==Explanation==
This is the second part of five in the "[[:Category:1337|1337]]" series. The title 1337 is "L-eet," or "elite," using the {{w|Leet}} alphabet, a coding system used primarily on the internet (and on early text messaging systems), meant to provide a bit of {{w|obfuscation}} to plain text both to make it harder to read and to show off in a creative way using in-group jargon.

This series was released on five consecutive days (Monday to Friday) and not over the usual schedule of three comics a week. These are all the comics in [[:Category:1337|1337 series]]:
* [[341: 1337: Part 1]]
* [[342: 1337: Part 2]]
* [[343: 1337: Part 3]]
* [[344: 1337: Part 4]]
* [[345: 1337: Part 5]]

"Like a ring in a bell" appears to be a reference to the {{w|Chuck Berry}} song {{w|Johnny B. Goode}}, in which Berry describes a young boy (like himself) who becomes a guitar-playing prodigy. The original lyric was "just like a-ringing a bell." Apparently, [[Help I'm trapped in a driver's license factory Elaine Roberts|Elaine Roberts]] learned to program as quickly, easily, and skillfully as Johnny (and Chuck) learned to play rock 'n' roll.
[[Donald Knuth]] is a computer science Professor Emeritus at {{w|Stanford University}} who is famous for writing {{w|The Art of Computer Programming}} and developing the TeX computerized typesetting system. He may not have a mountain hideaway (a reference to ''{{w|Kill Bill}}'', by the way, as is the whole training sequence), but he would be one of the best mentors a budding hacker could have.

The {{w|A* search algorithm}} and {{w|Dijkstra's algorithm}} are {{w|Graph traversal|graph search}} {{w|algorithm}}s. And what study of algorithms would be complete without a healthy study about finding complexities? {{w|Computational complexity theory|Time complexity}} is the amount of time an algorithm takes to execute. Upper bounds for complexity is written in {{w|Big O notation}}. Best possible execution of an algorithm is constant time, or O(1), said in words, for any given data set, no matter how large, the algorithm will always return the answer at the same time. However, constant time is extremely difficult to achieve; linear time (O(n)) is also very good. For more complex algorithms, [https://www.wolframalpha.com/input/?i=plot+x*log%28x%29 O( n*log(n) )] is good, but [https://www.wolframalpha.com/input/?i=plot+x*log%28log%28x%29%29 O( n*log(log(n)) )] is better. (Note that logarithms in different bases are proportional to each other. So, this would hold true for any base >1.)

Knowing that [[Mrs. Roberts]] has two children, this daughter named Elaine and the son named Bobby, is the key indicator that this is the mother previously noted as having given her children particularly strange names. Of course, the title text here explains that Elaine is only her middle name (assuming canonicity of title-text), but it was in the title text to [[327: Exploits of a Mom]] that we learned that her first name is "Help I'm trapped in a driver's license factory". Mrs. Roberts appears to have had fun naming her children.

==Transcript==
:[Cueball standing and looking down at his Cueball-like friend, who is sitting on the floor near an armchair holding a cloth to his face.]
:Friend: So the greatest hacker of our era is a cookie-baking mom?
:Cueball: Second-greatest.
:Friend: Oh?

:[The next panel is only half height as Cueball's narration is written as a caption above the panel without a frame around it. In the panel to the left lies a young Elaine with a ponytail on the floor typing at a keyboard while looking at a screen connected to a computer behind it with lots of wires and open case. The computer appears to have been pieced together and there is a screwdriver lying next to her and an open box lies behind her. Little Bobby Tables (a kid version of Cueball) is painting with a broad brush at an easel to the left. There is a clear drawing with two parts going up and one down, but it's not easy to see what it should look like. He is holding his other hand up in the air, like he is enjoying the painting.]
:Cueball (narrating): Mrs. Roberts had two children. Her son, Bobby, was never much for computers, but her daughter Elaine took to them like a ring in a bell.

:[The front of a car is in frame with side mirror and steering wheel visible. Mrs. Roberts is waving goodbye to her daughter who is wearing a backpack and is holding a walking stick. She is about to begin climbing a staircase built into a rocky mountain side. The first 11 step are visible. Behind the two and the stair are two distant mountain peaks, and above them two clouds. Cueball continues to narrate, this time inside the panel:]
:Cueball (narrating): When Elaine turned 11, her mother sent her to train under Donald Knuth in his mountain hideaway.

:[Donald Knuth, drawn with hair only around his neck, is standing with a pointing stick at a chalk board with graph traversal patterns on it and two blocks of unreadable text the top may be a matrix. This small panel is also lower than the next panel, with Cueball's narration above:]
:Cueball (narrating): For four years she studied algorithms.
:Donald Knuth: Child—

:[Donald Knuth whips around from the board slashing the stick like a sword. Elaine jumps, making a somersault (indicated with a line curving on it self from floor to sword) and lands on the stick balancing with her arms out.]
:Donald Knuth: Why is A* search wrong in this situation?
:Stick: ''swish''
:Elaine: Memory usage!
:Donald Knuth: What would you use?
:Elaine: Dijkstra's algorithm!

:[Donald Knuth and Elaine are outside, seen from behind while they are both writing on a chalkboard with a thick line down the middle to separate their work. On both sides their writing can be seen but it is unreadable. Where there is only text visible on Donald Knuth's side there is also what appears to be a drawing or matrix at the top of Elaine's. But a similar thing could be behind Donald Knuth's head. Elaine is no longer wearing her hair in a ponytail but have long straight white hair like her mom, Mrs. Roberts. To the left there is a stump from a tree, some grass and maybe a puddle of water. Further back there is a small jagged hill and a flat horizon. To the right there are four mountain peaks and a flat high plateau towards the horizon. The frame of the panel does not include the top-left and bottom-right corners, but cuts round a rectangular section of both places. In these two sections, outside the panel, are the last two paragraphs of Cueball's narrating:]
:Cueball (narrating): Until one day she bested her master
:Donald Knuth: So our lower bound here is O(n log n)
:Elaine: Nope. Got it in O(n log (log n))
:Cueball (narrating): And left.

==Trivia==
*In this [https://www.youtube.com/watch?v=zJOS0sV2a24#t=21m30s Google-speech] Donald Knuth personally asked [[Randall]] what his ''n*log(log(n))'' algorithm for searching was, and Randall referred him to Elaine.
*Elaine is actually her middle name.

I did a bit of a deep dive into wikipedia and the googology wiki and the answer to the last question depends on a few things (along with assuming ZFC). If transfinite ordinals count as numbers, then those at the end of {{w|List of large cardinal properties}} take the cake (if i'm reading it right). Otherwise, something based off [https://googology.fandom.com/wiki/Rayo%27s_number Rayo's number] is the best googologists have come up with so far.

:How about "On, in the context of MK set theory"? MK is a standard way to extend ZFC by allowing classes as mathematical objects, so On (the class of all set-size ordinals) is a class-sized "ordinal". But MK doesn't allow proper classes to be contained in any object, so "On+1" doesn't exist except as a definable hyperclass. Thus, On is the biggest "number" in a model of MK set theory.{{unsigned ip|172.68.205.151}}

::I qualify as a "post-grad math", and yet, I think infinity would have been a perfectly valid answer. Let me explain. The term "number" without further context is a bit vague, because there are several possible generalizations of natural numbers (something that presumably everyone agrees to call a "number"), and they are not compatible, ie. there is not a single generalization that generalizes them all. So we have to choose which generalization makes sense in the current context. Since the question is about thinking how big a number is, I naturally thought that the adequate generalization would be one that focuses on the order on natural numbers, ie. ordinals. In that case, my answer to this question would be "the class of numbers I can think of is not bounded, therefore there is no such thing such as a 'biggest number I can think of'". But if I had to write down a big number, I would write ε_{ε_{ε_{...}}} up until I filled the page, because that's the most efficient way I know to write a big, *big* infinity. Which is a number.

A number, by definition, is a construct used to classify and/or compare values. How rigorous this needs be for one limits the extent to which they accept things as being a number. Even things like "apple" could be interpreted as (dimensioned) numbers, with a possible value being "1 fruit"; In that regard, one may consider things like apple=orange<grapes.

Just "infinity" is nearly useless in this regard, as it's "no end thing". Usually interpreted (when necessary) as the countable infinite cardinal x=aleph_null, this prevents most useful comparisons, including dimensional analysis since x^n=x for all counting (aka. finite positive integer) n. Spacetime may or may not be boundless, but we can't tell how many edges may or may not loop. Is it infinity? Yes. Is it infinite? God only knows. Can you *count to it*? God can. Does that make it a number? Depends. Is "infinity plus one" a sane concept? No, it can't be finite, ordinal, and/or real in a way addition is defined; It's without end, and if you could add to it, that would indicate an end.

In contrast, classification has its roots in trade, and barter, and tipping. How much of a thing is enough, but not too much. Somebody may accept between 1/2 and 2/3 of a pie you're splitting, because less wouldn't be fair and more may give them a stomach ache; Is 3<=6x<=4 a number? It's similar in uselessness to "infinity", but whether something is less or more can at least still be established within its range. In the limit, Surreal numbers are the principal example of classification, taking the arithmetic mean of the maximum and minimum of their lower and upper bounds, or the predecessor or successor, or zero. For example, y={y|1} is the biggest number less than one, with z<=y<1 for all z<1. It's less than one, but not any "smaller" than one, with an immeasurably infinitesimal difference 0<1-y.

Choice of axioms is very important for all this, since its full extent can render everything except finite non-negative integers "not a number" (by Presburger Arithmetic), or allow everything up to and including unique antichain cardinalities (by Martin's Maximum).

The sixth power of the smallest ordinal with the cardinality of the continuum in the constructed universe (w_1^6 where beth_n=C(w_n)) is the biggest number I can personally conceptualize, although I can consistently work with w_2 in this system as well. Does the fact that this is infinite make it any less useful as a number than 2.5? No. It says I can think accurately about all the standard ways of comparing things in up to 6 infinitely divisible dimensions. Just because one cannot necessarily picture something others can't doesn't mean it doesn't exist. If a one-eyed person can only see a 2 spatial + 1 temporal dimensional image, that doesn't mean depth doesn't exist, it just means it's "hidden" from that perspective. 3+1+2 has two "hidden" dimensions compared to normal 3+1 spacetime, and beth_1 is infinitely divisible unlike the quantum (at most beth_0) nature of our known universe, but I can still work with 3+1+1, and 3+1+2 in the same way people can think about a (possibly looping) universe where everything can be bigger or smaller, and spatial geometry itself may be some degree of spherical, and people have been working with fractions since antiquity, so why should I limit myself to what other people can grasp?

In summary: "number" is too vague for claiming most things "aren't" to be reasonable. Infinite values (that aren't just "infinity", that's vague enough by itself to be almost as unreasonable) are just one one example of a valid answer most people seem to be up in arms about.

:From the image you can assume an 9/20 aspect ratio. Assuming each rotation reduces the image dimensions by that fraction after 9 rotations the dimensions would be reduced 1322 times so the resolution would be something between 1322x595 pixels (anything less than that would made it require 8 rotations or less) to 2935x1321 pixels (anything beyond that would require 10 rotations or more). 1600x720 or 2400x1080 maybe? Applying the same formula for the phone width and assuming atoms are typically around 100 picometers across then the phone width is close to 4.67 cm, too small, but maybe that's because rounding. In the other hand that formula does not work with Planck length at all: using it the phone width would be 1.69 meters.

::I took almost the reverse approach. Estimate phone height is 0.2 metres, Planck length is 1.6e-35 metres, ratio is 1.25e34, then take the 101th root. That would give about 2.176 as the reduction factor, which is also the screen aspect ratio. Then ask, "how far off might this be?" I assumed the 101th reduction is just barely smaller than the Planck length, it could be almost another reduction and still work. In other words, the aspect ratio is constrained to be between the 101th root and the 102nd root of the screen height in Planck units. With a 20 cm high screen, that puts the aspect ratio between 2.159 and 2.176 -- so the 9:20 aspect ratio (2.222) is completely ruled out. However <s>all the</s> [https://mediag.com/blog/popular-screen-resolutions-designing-for-all/ latest iPhone sizes] work just fine: 1792/828=2.164, <s>2436/1125=2.165, 2688/1242=2.164, 2436/1125=2.165</s>. I'll just guess that Randall has one of those. [[User:Mrob27|Mrob27]] ([[User talk:Mrob27|talk]]) 06:41, 13 September 2022 (UTC)
::Adding: I forgot to apply your method to constrain the width in pixels. 1125 and 1242 is ruled out because they are bigger than 2.159^9.

This seems like it could actually be really cool. Can anyone do this and put the picture here as an example? Also, if possible, include an AI upscale of the one pixel. [[Special:Contributions/172.69.90.83|172.69.90.83]] 19:07, 12 September 2022 (UTC)

There's a '''minor''' counting error: instead of pointing to the 9th rotation, the 'nine rotations' statement points to the 8th as the first phone has no rotations.[[Special:Contributions/172.70.90.77|172.70.90.77]] 19:10, 12 September 2022 (UTC)
:That error is also on the 25 rotation, in both cases he counts the first screen with, and thus is one rotation behind. Also there are only 99 screens and thus 98 rotations so he missed the last 3 rotations, and screens, as there should have been 102 screens. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 09:06, 13 September 2022 (UTC)

Doing this with an jpeg does the same. When rotating an image and saving it the lossy compression will lose more pixels. This makes it more blurry each step. [[Special:Contributions/162.158.203.38|162.158.203.38]] 22:41, 12 September 2022 (UTC)

:Who said it had to be something like JPEG? Since the information added at each step is known and finite, you could easily devise an iterated rotated image format that perfectly preserves the detail at every level down to the Planck length, and provide the possibility of zooming in on the screen all the way down. Of course you couldn't *display* all the detail at every level at the same time, but you could certainly store it in a hypothetical IRI (tm) format.

I'm skeptical of "details at a sub-pixel level but that would have been significant if recorded at a greater resolution ''cannot'' emerge" -- this is subjective at a couple levels, and not as entirely impossible as opposed to just vaguely unlikely as the italics imply.

:Well, after finding the context... Using pixel-multiplying techniques on low-res pixels (either direct, a poor imaging source, or upon previously downsampled high-res one) will either never recreate features 'lost' in the lower resolution or will ''always'' do (or at least always in a given non-zero proportion of pixel-patternations indistinguishable from the more justified one) even in situations where there was no justification for such an algorithmically-invoked artefact.
:But I suppose the most perfect fractal-compression, if it matches 'reality' well enough, could be rediscovered by the statistical pixel analysis which then extrapolates (or interpolates) all kinds of image details that were never even present even in the rawest of raw digital images but were always there to be discovered in the real-world had only the correct zoom level and framing been used. And, if you've got something that can do that, I'll up the stakes with the Photo Enhancer/Inferrer thing that Rick Deckard used... It can even interpolate ''around corners''!

I thought Randall was poking fun at all the dumb movies and TV programs that have the magic ability to “enhance” images and recover sub-pixel detail. It’s such an egregious plot point that you can recognize computer scientists by their groans in movie theaters. There’s even a TV Trope about it: https://tvtropes.org/pmwiki/pmwiki.php/Main/EnhanceButton — Also, the infinitely regressing image is called a ''Droste Image''. --[[User:Dúthomhas|Dúthomhas]] ([[User talk:Dúthomhas|talk]]) 08:08, 14 September 2022 (UTC)
