{{incomplete|CreAAAAAAAAAted by AAAAAAAAAAA BOT - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This is a crossword puzzle where every single answer consists only of the letter "A". On a surface level, however, the answers seem extremely difficult, with some involving base conversions, and some involving the wordplay typical of the crossword style.

{| class=“wikitable” style=“margin:auto”
|-
! Location !! Clue !! Explanation
|-
| 1-Across || Famous Pvt. Wilhelm quote || Reference to the {{w|Wilhelm scream}}.
|-
| 11-Across || IPv6 address record || An IPv4 record is an "A" record, an IPv6 record is four times the length and is designated an "AAAA" record.
|-
| 15-Across || “CIPHERTEXT” decrypted with Vigenère key “CIPHERTEXT” || A "{{w|Vigenère Cipher}}" translates the original text by the distance from A from the key, letter by letter. For instance, if the plaintext is "XK" and the key is "CD", the C shifts X 2 forward to become Z, and the D shifts K 3 forward to become N, yielding a ciphertext of "ZN". Since the ciphertext and the key are the same in this case, decryption just shifts all the letters back to A, akin to subtracting a number from itself and getting 0.
|-
| 16-Across || 8mm diameter battery || A {{w|AAAA battery}} is a 1.5V battery that measures 8.3mm in diameter, 2.2mm smaller than the more common AAA battery.
|-
| 17-Across || “Warthog” attack aircraft || The {{w|A-10 Warthog}} is a well-known attack aircraft. Here, A-10 has been turned into AAAAAAAAAA (ten As).
|-
| 18-Across || Every third letter in the word for “inability to visualize” || Aphantasia is the inability to visualize. Following the instruction, we determine that '''A'''ph'''a'''nt'''a'''si'''a''' gives us the word "aaaa".
|-
| 19-Across || An acrostic hidden on the first page of the dictionary || The first page of the dictionary (if you ignore the copyright page and the index) is the list of words starting with A. An acrostic of this page, taking the first letter of each line and arranging them in order, would just be a sequence of A's, as most of the answers to this crossword are {{citation needed}}.
|-
| 21-Across || Default paper size in Europe || {{w|A4 paper}} (here written as AAAA) is the default size in Europe. At 210x297mm, it is approximately 0.24" narrower and 0.71" longer than the 8.5"x11" paper used in the United States, and due to having an aspect ratio of 1:sqrt(2), can be cut in half to create two half-sized sheets with exactly the same aspect ratio.
|-
| 22-Across || First four unary strings || Unary's when you get to use just the one symbol. E.g. 32 in unary would be 11111111111111111111111111111111. The first four strings in unary, if you used A as the first (and only) symbol, would be A, AA, AAA, AAAA.
|-

He famously [https://www.youtube.com/watch?v=l6i-gYRAwM0 yelled at a rally] in a way that was thought to be bizarre and which, it is thought, doomed his campaign.
|-

The scream could be transcribed as "AAAAAAAAAAA"
|-

|-

|-

|-
| 4-Down || It’s five times better than that other steak sauce || 5 times better than {{w|A1 steak sauce}} would be A5, stylized in this puzzle as "AAAAA"

|-
| 6-Down || Freddie Mercury lyric from Under Pressure ||
|-
| 7-Down || Full-size Audi luxury sedan || Second of three Audi references. As mentioned previously, the A8 is their full-size luxury sedan.
|-
| 8-Down || Fast path through a multiple choice marketing survey || The "fast path" is just to select the first option over and over again. Usually the options are labeled A, B, C, and D (or more) - choosing the first option for every question would be answering entirely with A's.

|-

|-
| 20-Down || Mario button presses to ascent Minas Tirith’s walls || {{w|Minas Tirith}}. In Mario games you typically use the A button to jump. In games where you don't press a button to move (e.g. games with a joystick) then the button presses required to ascend a vertical structure would probably all be A. This clue might have been inspired by the {{w|A-button challenge}} / [https://ukikipedia.net/wiki/A_Button_Challenge A Button Challenge], which tallies the amount of A presses needed to beat ''Super Mario 64''. Additionally, Minas Tirith is a city with seven concentric rings, each with a wall around it and higher than the last ring. Presumably, it takes seven jumps to get to the highest area of the city, so the answer is "AAAAAAA"

2541: Occam

2021-11-20T01:03:24Z

162.158.62.56: removed extraneous sentence

{{comic
| number = 2541
| date = November 12, 2021
| title = Occam
| image = occam.png
| titletext = Oh no, Murphy just picked up the razor.
}}

==Explanation==
{{incomplete|Created by a BOT THAT CREATES ALL PAGES NOT MENTIONING ITSELF AND NO OTHER PAGES - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic conflates three philosophical topics: {{w|Occam's Razor}}, the {{w|Barber paradox|Barber Paradox}} and {{w|Murphy's Law}}.

Occam's Razor is the principle that explanations should not postulate more entities than necessary. It is often phrased as "the simplest explanation is best". The word '{{w|Philosophical razor|razor}}' is intended to evoke the image of shaving off superfluous elements.

The Barber Paradox postulates a town barber who shaves all those, and those only, in the town who don’t shave themselves, and asks whether the barber shaves himself. The paradox is that if he does, then he shouldn’t, and if he doesn’t, then he should. It is an attempt at a concrete, real-world analogue of {{w|Russell's paradox|Russell's Paradox}} in set theory.

Megan references Occam's Razor with the words "the simplest explanation" and the name Occam, and goes on to propose a solution to who shaves the barber. Strictly speaking, Occam (or {{w|Ockham}}) is a village in Surrey, where the friar and philosopher William of Occam lived, so it would be more correct to say that "William shaves the barber," but that wouldn't get her meaning across as clearly. (Her proposal is humorous and does not of course resolve the paradox, as the barber is still not shaving himself, so he should shave himself, so he shouldn't shave himself...)

The title text invokes Murphy's Law: the expectation that "anything that can go wrong will go wrong." When you shave with a {{w|Straight razor|cut-throat razor}}, there's multiple things that could {{w|Sweeney Todd|go wrong}}, many of which would cause harm to the person being shaved. Alternatively, invoking Murphy's law makes the principle of Occam's Razor itself, or its use in the comic, "go wrong", possibly rendering the solution invalid.

2532: Censored Vaccine Card

2021-10-22T22:46:33Z

162.158.62.56:

{{comic
| number = 2532
| date = October 22, 2021
| title = Censored Vaccine Card
| image = censored_vaccine_card.png
| titletext = CVS's pharmacies are fine, but I much prefer their [censored]s.
}}

==Explanation==
{{incomplete|Created by a B[Censored]T - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
This comic is loosely related to a series of comics related to the 2020 pandemic of the coronavirus SARS-CoV-2, which causes COVID-19.

The comic hinges on sharing photos on social media of vaccination cards as proof that the user has been vaccinated (in this case, gotten a booster shot). Such cards contain personal identification that should probably not be made public. The irony is that the user has censored some impersonal lines, such as the instructions that are identical on all vaccination cards, and many easy-to-guess lines, while not censoring any of said personal information.
The fourth line, labelled "other" is probably completely blank (as the third dose was on the current date), but is completely blacked out.

The caption indicates that his intention is to "seem more mysterious". This is best exemplified by blanking most of the word "clinician" to leave "CIA".

The current incomplete tag asks why voice 1 calls Joe Biden "the man" and voice 2 calls him J.B. As far as I can see, there is no deeper/cryptic meaning to the choice of these words, other than possible space saving. Both 'J.B.' and 'the man' are shorter than 'Joe Biden'.

I do take a funny sense of satisfaction in Joe Biden being VP at the time of this comic's publishing and now being President. I don't know why; I don't even like the man's politics.

Talk:2529: Unsolved Math Problems

2021-10-16T13:21:35Z

162.158.62.56:

Center panel possibly related to "The drunkards walk" and theories on randomised motion.
https://www.quantamagazine.org/random-walk-puzzle-solution-20160907/
More references https://mathworld.wolfram.com/RandomWalk.html

Someone's gotta point out that "walking randomly on a grid, never visiting the same square twice" would rapidly trap you in a corner (even the example has a 50/50 chance of that happening on the next move) [[Special:Contributions/172.70.130.125|172.70.130.125]] 04:29, 16 October 2021 (UTC)

Not if it's an infinite grid.

I think there's two different ways to interpret the question - as a uniform random element of the set of all non-self-intersection NxK length paths, in which case it's fine, or as a path defined by a random walk in which moves onto your own path are not allowed, which doesn't seem well defined, since you might end up in a situation where you are surrounded by your own path and cannot continue for all NxK steps.

An early example of a cursed problem is the Cantor Function. https://en.wikipedia.org/wiki/Cantor_function

I admire whoever wrote the description of the curve in the "cursed" panel. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 05:36, 16 October 2021 (UTC)

"Algebreic" is a misspelling of "algebraic". Could Randall really have made this mistake, or is it another malamanteu? What does "breic" come from? [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 06:10, 16 October 2021 (UTC)

I wonder if Randall was actually referring to that quote about "Into the Woods", or he just thought "Sondheim calculus" sounded cool and it was a total coincidence. I found it when I googled "sondheim calculus" to make sure it wasn't a real thing. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 06:29, 16 October 2021 (UTC)

To me, the cursed curve looks a bit like a crosier https://commons.m.wikimedia.org/wiki/File:Crosiere_of_arcbishop_Heinrich_of_Finstingen.jpg

--> I had the same impression and added it. --[[Special:Contributions/162.158.94.219|162.158.94.219]] 11:40, 16 October 2021 (UTC)

No explanation of the "Euler Field Manifold Hypergroup (Isomorphic to a)..." part?

The cursed curve looks almost like someone took a graph of the Binet formula, stretched it out a bit, and rotated it onto the y axis.

162.158.62.56: added Re for pneumatic tires

Great work by whomever did this, but is it possible R_e is something else? I agree that the numerical aspect makes it seem like a fluid mechanics problem, but I've never seen the Reynolds number with a subscripted e... only a regular size e, such that it is Re, not R_e.

: R sub e (not Re) is Effective Reproduction Number. This is related to infection rates. I'm pretty sure it's R sub e, not Re given that infection rates are very much on his mind right now.
:: It would be out of place relative to all the other entries, though, which are all physics related. IMO it's more likely this was an error.
: Earth's radius is abbreviated "R sub e" [[Special:Contributions/162.158.107.4|162.158.107.4]] 21:30, 24 September 2021 (UTC)
: Could be the remainder of a series (i.e. the error when using the first terms of the series as an approximation). Determining upper bounds on this error is usually very tedious.
: R sub e is tire effective rolling radius (or effective radius)--a radius based on the distance traveled by one rotation of a pneumatic tire. Re is similar to the unloaded radius (for radial tires) and normally larger than the loaded radius (distance from axle to ground).

T to the fourth power looks like blackbody radiation, any ideas what specifically that formula represents? [[Special:Contributions/162.158.203.22|162.158.203.22]] 20:40, 24 September 2021 (UTC)
:There's an equation for what reflects off a spherical object that is a quartic equation (although I'd expect concave reflectors, not convex ones, to risk skin-burn. Or, more likely something to do with UV (non-)absorbtion or generation, but I imagine someone knows ''exactly'' what it is, without someone like me just guessing wildly. ;) [[Special:Contributions/141.101.99.82|141.101.99.82]] 21:05, 24 September 2021 (UTC)
This wiki does not seem to have a consistent formatting structure for lists

The ''NA'' could also soon become NAN (not a number) thus being only a step away from the dangerous arthmeric error. --[[Special:Contributions/162.158.88.43|162.158.88.43]] 21:38, 24 September 2021 (UTC)

'''Bold Title'''
:Content starting with a tab

*'''Bold title''' content continues on same line

*Regular title
Content on a new line, but not starting with a tab

As well as tables and mixes of these formats. Maybe someone should pick one and apply it to all the explanations. I just noticed it because of the inconsistencies as people are quickly throwing something together for this new comic.

I read the penultimate line as "Mg" and was trying to imagine a meaning for "megagrams per kilogram". Sloppy Greek letter there, Randall. [[User:Nitpicking|Nitpicking]] ([[User talk:Nitpicking|talk]]) 03:17, 25 September 2021 (UTC)

Why are partial derivatives considered graduate-level? They're typically covered in first level undergraduate science courses, along with gradients and such. [[User:FPSCanarussia|FPSCanarussia]] ([[User talk:FPSCanarussia|talk]]) 03:34, 25 September 2021 (UTC)
