this math shit is NOT easy
@chrisisgr8 uh... that looks really bouba to me ._.
@SehrLesbisch @chrisisgr8 equations that use a/b/c for the variables are bouba, ones that use x/y/z are kiki

@funkula @chrisisgr8 no it's the numbers

they're very round

@SehrLesbisch @funkula @chrisisgr8 for me, even degree polynomials are bouba and odd degree polynomials are kiki
@chrisisgr8 interesting, I would think all parabolas are bouba
@chrisisgr8 honestly this sums up my mathematical career - I'm great at kiki math but struggle with the more advanced bouba math
@spacefinner but... bouba math is the smooth and continuous math... that should be the easy math
@photon @spacefinner No way, that's that scary physicist type of math. Kiki math is way easier for my CS brain
@photon
What's great about this reply is yes, you have it right! Smooth and continuous math is indeed bouba to me and also considerably less intuitive.
@chrisisgr8 I'm sorry, that answer is wrong, quadratic functions are inherently boba.
@skysailor  this math stuff is so hard
@skysailor @chrisisgr8 hmm i vote for quadratic functions are bouba IFF they only have integer roots
@skysailor @chrisisgr8
All continuously-differentiable functions are bouba. Functions with discontinuities in any of their derivatives are kiki.
@petealexharris @skysailor @chrisisgr8 but consider y = exp(-1/x^2), x != 0; y=0, x = 0. Infinitely differentiable and yet mathematically kiki.
@skysailor @chrisisgr8 can't believe people don't see this!
@chrisisgr8 @Sugui i'd say bouba, because it has very nice divisible numbers
@chrisisgr8 it can be either, depending on how you look at it
@chrisisgr8 the second question sounds a bit more interesting
@chrisisgr8 excuse me that's a non-degenerate parabola that's clearly bouba
@chrisisgr8 I love how the fediverse is full of people who noticed that this answer is clearly wrong, because parabolas are bouba :)
@chrisisgr8 but what was your answer to the second question about the function?
@chrisisgr8 it is bouba, obviously, because the numbers 3, 12 and 9 are bouba. #synaesthesia #coloredNumbers edit: corrected autocorrect nonsense
@chrisisgr8 I don't know if x^2 isn't also still kiki, but 3x^2 most def. is
@chrisisgr8
Wassit say at the bottom?
Seems like "Does the function fuck?" to me 😄
@chrisisgr8 bouba. It's a parabolic curve much like the "round" sound of "bouba"
@chrisisgr8 It is often said that real analysis is the study of how kiki a function can be, while complex analysis is the study of how bouba a function can be
@chrisisgr8 It's Kiki & it does NOT fuck.
@chrisisgr8 Well, since it's negative, it's Kiki because it's curved up instead of curved down. Also it fucks (the question below) since it has two solutions. Because it means it crosses the X axis twice. That's basically the Y axis fucking the X axis.
@chrisisgr8 Surely it's bouba? It's so factorable!
@chrisisgr8 there is only one parabola shape, so it only depends on whether any parabola displayed is Bouba or Kiki to you https://www.youtube.com/watch?v=hoh4TmPzu1w
There is only One True Parabola

@chrisisgr8 "does the function fuck?"
@smolbean32 @chrisisgr8 Yes, I thought this was the harder question... It's clearly boub-ki.

@chrisisgr8

looking at a quadratic function
ask the professor if the function is bouba or kiki
she doesn't understand
pull out illustrated diagram explaining what is bouba and what is kiki
she laughs and says "it's a good function"
mark my answer
its bouba

@chrisisgr8 But .... A kiki is a party for calming down your nerves?? 🥺 And booba supposed to be soft and warm when world hard and cold? 😶 What kinda Wachowskian shenanigans is going on here? 😬
@chrisisgr8 This is bouba. All the numbers (except the exponent) divide nicely by three. Big fan
@chrisisgr8 absolutely bouba, no question about it

@chrisisgr8

It's math with letters involved == automatic kiki.

@chrisisgr8 this function is obviously bouba
@chrisisgr8 if the academy will have it, i put forward that functions should be regarded as kiki if they have points of inflection where the second derivative changes sign and functions that do not as bouba
@Tessa @chrisisgr8 that's my first impulse too. or piecewise functions

@0x4d6165 @chrisisgr8 @Tessa I would say most algebraic functions are bouba, while step functions and any function with a discontinuity would be kiki.

And there is probably a kiki-bouba spectrum that functions can be ordered onto.

@chrisisgr8 this does however imply that the Cantor function is bouba which feels very wrong so maybe the definition should be broaded to define that functions that are not twice differentiable are also kiki
@chrisisgr8 Bouba but does fuck
@chrisisgr8 the function does not, indeed, fuck.
@chrisisgr8 What wonderful math-related learning opportunity! Nerd be with you!
@chrisisgr8 I feel like almost all functions that are differentiable across their entire domain are bouba.
