Editing Talk:2492: Commonly Mispronounced Equations

<!--Please sign your posts with ~~~~ and don't delete this text. New comments should be added at the bottom.-->

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.

:"Doot-ca-doox" is so funny.  I'm imagining Pingu saying that.  !!!!

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)
::You ask how it's a mnemonic, yet you say you've seen it before. Think about that for a sec.
[[User:Klo876|Klo876]] ([[User talk:Klo876|talk]]) 01:58, 24 July 2021 (UTC)
::Not sure it's a mnemonic, no, but I was taught SOHCAHTOA by a very good (but strict) maths teacher as in "... (like?) that volcanic eruption". Given we were 10, 11 years old, I don't think we even ''knew'' about {{w|Krakatoa}} at that point (despite having also a very good Geography teacher who readily identified lumps of 'Gneissian schist' that I may have brought back from holiday - he also had a much better sense of humour...) so whether I (or the teacher?) was mistaken in understanding "Sohcahtoa" to be purported to be a (now ironically memorable) volcano rather than it was a "it rhymes with..." mnemonic, I don't now know. But since then I have always used SOHCAHTOA to confirm in my mind which trigonometric identity I should use. And, later, I learnt and never forgot that {{w|Krakatoa,_East_of_Java|Krakatoa is/was ''west'' of Java}}! [[Special:Contributions/141.101.98.230|141.101.98.230]] 08:20, 23 July 2021 (UTC)
::(PS - If I ever have to use the "Many Very Elderly Men Just..." mnemonic (or whatever it is, I was sure it had had Earthenware Vases, but maybe only in a reversed version!), I tend to have to ''backform'' it from my unclear recollection of the mnemonic(s) I've been told plus just ''knowing'' that it's "Mercury, Venus, Earth, Mars, **, Jupiter, Saturn, Uranus, Neptune*, Pluto-if-we're-counting-it*" (* - except between 1979 and 1999 when it was "...Pluto-definity-counted-at-this-time, Neptune") (** - and then there's possibly an A, B or C here for Asteroid, Belt or Ceres; nobody I know has ever added Kuiper and/or Oort into the string of words to need remembering, though) using very non-mnemonical direct or indirect knowledge about the solar-system, like Clarke's written version of 2001 aiming at Saturn but Kubrik's film 'only' going as far as Jupiter. So I "(Sometimes?) Might Very Earnestly Make And Join Something Unprecedented Never Known Originally" on the spur of the moment.)
:: The point of soh-cah-toa is that you learn to say it aloud as one word (which is therefore memorable), and then can expand it out as an acronym for sin(x) = o/h, cos(x) = a/h, tan(x) = o/a, which wouldn't be memorable. Much like BIDMAS/PEDMAS is pronounced as one word to learn an acronym. [[Special:Contributions/162.158.158.176|162.158.158.176]] 18:32, 26 July 2021 (UTC)
::: BIDMAS/PEDMAS '''is/are''' the acronym (a string of initials pronouncible/pronounced as a word), used as a mnemonic to recall and learn the maths.
:The circle area might be meant to read out like "upper two", referencing the square. I can't see the same for any of the others though. / [[Special:Contributions/162.158.183.157|162.158.183.157]] 06:52, 22 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.  Mind you, as a math tutor, my first thought was that these were attempts at mnemonics that missed the mark, '''badly'''.

The Pythagorean Theorem one made me think of the AT-AT debate for Star Wars

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.


It would be interesting to try and reverse-engineer the original equations behind, for example, "Fus ro dah", or "Avada Kedavra". [[User:Cavaler|Cavaler]] ([[User talk:Cavaler|talk]]) 12:53, 23 July 2021 (UTC)

What is the pronounciation notation this comic is using?? I can't even find them in Oxford/Cambridge/Merriam-Webster/Collins dictionary, though I think I occasionally see them somewhere else. --[[User:Lamty101|Lamty101]] ([[User talk:Lamty101|talk]]) 08:43, 24 July 2021 (UTC)
: It's probably not actually right to consider it a notation, ''per se''. It's a trivial method that anyone can use (no need to use funny stuff like ɛ, ʑ or ɖʐ in IPA notation - or remember what they mean!), but it's also liable to inconsistency as you can be inconsistent in both production (some might consider "DOO" ''or'' "DU" an acceptible rendering for the same thing) or understanding (if "BAI" is written used, was that as in "good''bye''" (see also "BIE") or "e''Bay''" (also could have been "BAE"), etc?). How would you indicate syllable boundaries, "IN-DUH-KAYT" or "IND-UCK-ATE" or ? A Cockney or a Kiwi or a Cajun might each produce ''and'' voice notations completely differently. But it's better than nothing. And with either bolding (as in here), italicising or uppercase-contrasting-with-the-rest-in-lowercase you can indicate the stressed syllable(s). Maybe look at {{w|Pronunciation respelling for English}} (I didn't see a further link to qualify any 'standards' for this non-phonomic system, and doubt that there are any that travel well beyond any actual particular narrow dialectical territory).
: I actually think it's part of the joke that it's an imprecise 'pronunciation guide', rather than a technically advanced one like /aɪ pʰiː eɪ/ itself is, further confusing the deliberately confused issue. [[Special:Contributions/141.101.99.29|141.101.99.29]] 19:45, 24 July 2021 (UTC)

We teach the impulse-momentum equation f*(delta)t = m*deltaV as FAT MAV. And you're far more likely to hear a mentor remind a student to use 'FAT MAV' than 'the impulse-momentum equation' this comic seemed an obvious evolution that idea.

Something similar does indeed happen in reality, when you have to read things like tan y = sinh x, cot y = csch x. Many people read sinh like sin-ch, while some others read it as shine, etc. [[User:Yosei|Yosei]] ([[User talk:Yosei|talk]]) 23:22, 17 August 2021 (UTC)
