I wonder if mathematical research breakthroughs can only become more complex and niche over time, or if there are still simple discoveries out there lurking in everybody's blind spots

Just found out that 15 April is Euler's birthday :euler: ๐ŸŽ‚ ๐ŸŽ‰

Adding "not-a-knot" to the growing glossary of annoyingly confusing mathematical terminology

The PPAP operator is recursively defined:

PPAP(x, y) = (y, x) if |x| = |y| = 1

PPAP(X, Y) = (PPAP(Y), X) if |X| = |Y| = 2^n > 1

E.g.

PPAP(๐Ÿ–‹, ๐Ÿ) = (๐Ÿ, ๐Ÿ–‹)

PPAP(๐Ÿ–‹, ๐Ÿ) = (๐Ÿ, ๐Ÿ–‹)

PPAP(๐Ÿ, ๐Ÿ–‹, ๐Ÿ, ๐Ÿ–‹) = (๐Ÿ–‹, ๐Ÿ, ๐Ÿ, ๐Ÿ–‹)

Huh, dunno if it's because of the hype around (or in spite of it), but SIAM is starting a new journal focused on that domain soon: siam.org/journals/pdf/flyer_si

I've finally got round to writing a code of conduct for mathstodon.xyz, guided by the MathsJam gathering code of conduct.
It's on the instance's about page at mathstodon.xyz/about/more
Looks reasonable?

Not sure how many of you may have seen this, but here's a pretty neat execution of on a game show (disclaimer: there's only sound from the right channel) youtube.com/watch?v=S0qjK3TWZE

Recent shenanigans involve wrestling with and for assignments, trying to translate the dang algorithms to working code

I've started with a general account on mstdn.io not too long ago, but I thought I might as well be here on mathstodon too, since I'm also a current applied maths undergrad. Think this place might be more receptive of my more mathematical activities :p
