108.162.221.220: add comment

This comic is obviously a take on the generation Z style of writing words without vowels so that they fit on T-Shirts, text messages or to avoid censorship, like "BRLN", "O RLY", "PIX PLZ". Some of the people from that generation are now established scientist, leading their respective fields forward. Obviously this is how they refer to common equations.

I think the wave equation is wrong based on units, but it's been a while. The wave speed ought to be squared. Of course, ''c'' could be a squared speed, but it's usually not. [[Special:Contributions/172.70.34.164|172.70.34.164]] 01:22, 22 July 2021 (UTC)

:I agree, normally it's written as C squared... The equations in order are 1: Gravitational Attraction, 2: Einstein's Mass / Energy Conversion, 3: Pythagorean Theorem (triangle side relations), 4: Area of a Circle, 5: Entropy equation, 6: Ideal Gas Law, 7: Euler's Identity, 8: Newtons Second law, 9: Wave equation, 10: The derivative of a function f, and, 11: The Quadratic Equation... I don't understand the linguistic rules being applied to the names, but they seem to be visual as much as anything [[Special:Contributions/108.162.237.66|108.162.237.66]] 02:04, 22 July 2021 (UTC)

My friends and I actually pretty often say "PəV-nert" for the ideal gas law. First syllable is kind of vowel-less, sort of a schwa if anything. But also stressed? Didn't know you could stress a schwa but, guess I did.

I tried to transcribe these pronunciations into IPA, because reading them like this is kind of ambiguous. I probably got a bunch of stuff wrong though.

The most similar time when equations are actually 'pronounced' a bit like this is the "soh cah toa" mnemonic for the trigonometric identities - should this be in the explanation? (the comic made at least me think that might be the original inspiration) [[Special:Contributions/141.101.99.204|141.101.99.204]] 06:42, 22 July 2021 (UTC)

:How is "soh cah toa" a mnemonic?? It's just a bunch of random letters. Normally you memorize random letters by coming up with words that fit together, not vice versa. I think this is much harder to remember than the thing it is supposedly a mnemonic for. If anyone actually finds it useful, can you explain how it works for you? I've seen this before so I suppose it's a real thing, but I find it baffling. [[Special:Contributions/108.162.221.220|108.162.221.220]] 04:15, 23 July 2021 (UTC)

:Mneumonics are supposed to make it easier to remember the equations; this collection would actually make it more challenging to remember these.

I don't think it's clear if the provided pronunciations are the ''Correct'' ones or the common ''mispronunciations''

It's worth noting that the majority of these equations are especially likely to be elided, and that the way they're routinely elided is generally incorrect - and more than that, the stressed syllable in particular is likely wrong. Especially notably "Fu-Jam-Er" should be "Fu-Gam-Er" and "Pav-Nert" should be "Piv-Nert". The joke works on the level of equation pronunciation being pretty intrinsically funny if you're not familiar with the specific equation, but also on the level of the specific equations having a standard pronunciation that pointedly isn't the one in the comic.

1533: Antique Factory

2015-06-03T11:46:15Z

108.162.221.220: /* Explanation */ Explained the title text.

{{comic
| number = 1533
| date = June 3, 2015
| title = Antique Factory
| image = Antique_Factory.PNG
| titletext = WARNING: This item was aged by the same inexorable passage of time that also processes nuts.
}}
==Explanation==
{{incomplete|This antique has just recently been constructed.}}
[[Beret Guy]] seems to have another new job with a confusing premise. When asked where he works, he says "an {{w|antique}} factory", which seems to be a contradiction. He walks up to a chair, table, and small cabinet, sits down in the chair, and does nothing else. Of course, one does not simply make antiques. Instead, one must wait. Beret Guy appears to be doing exactly this. The implication is that the "antique factory" is simply a place where furniture is stored until it gets old enough to be considered "antique", and that Beret Guy doesn't perform any useful function (except perhaps to keep an eye on the inventory so it doesn't get stolen).

The title text refers to allergy warning labels that say "Manufactured in a facility which processes nuts",
"Manufactured on equipment that processes products containing nuts",
"Manufactured on equipment that uses nuts", or similar. Sometimes these warnings are used for allergens besides nuts, but nuts may be the most common. The joke here is that of course time affects both antiques and nuts; time affects everything, and may even effect some things. (See [[326: Effect an Effect]].)

141: Parody Week: Achewood

2015-06-03T11:44:41Z

108.162.221.220: /* Explanation */ fixed your brackets for you

{{comic
| number = 141
| date = August 14, 2006
| title = Parody Week: Achewood
| image = achewood.png
| titletext = I always wanted to impress them with how well I could hear, didn't you? Also, this sets the record for number of awkward-pause panels in one strip (previously held by Achewood)
}}

==Explanation==
{{w|Achewood}} is a webcomic by {{w|Chris Onstad}}. It portrays the lives of a group of anthropomorphic stuffed toys, robots, and pets. The comic's humor often lacks a traditional punchline, and utilizes numerous awkward pause panels.

This comic includes three of the prominent characters from the strip: Phillippe, Ray and Roast Beef. In the first panel, Phillippe is dreaming of having his ears checked. There's an eye chart on the wall behind him. The doctor informs him that because of his superhearing power he is needed at Hogwarts.

Afterwards, the comic is a conversation between Roast Beef and Ray about Ray being invited to participate in what seem to be a talent show, with no further reference to Philippe.

The comic is written in the style of Onstad and his humor. The last 11 panels are "awkward-pause panels", which are used frequently in Achewood, in what appears to be a joke about overuse of dialogue-free panels. This joke is continued in the title-text, where [[Randall]] claims that this strip set the record for panels of this kind, previously held by Archewood.

Sweet Sweetback's Badasssss Song is a 1971 {{w|Blaxploitation}}film that is generally regarded as an exemplar of its genre.

This comic is a part of the Parody Week, just joking about other webcomics.
