@JDHamkins Fails in the 2-adics too.
But that’s to be expected, it looks like a chaotic map with lots of orbits.
Don’t know much about the natural ring of ordinals
English
I have realized that the Collatz conjecture fails in the natural ring of ordinals...

Any field extension E → F of finite degree n can be represented as a sub-algebra of nxn E- matrices.
Proof: Choose E-basis for F, and represent every element x of F by matrix corresponding to multiplication by x.

i just had the realisation that multiplication of complex numbers is basically just matrix muplication.

@chloeallegra228 @miniapeur no. same as video but in reverse. start from tail, go clockwise round

@Almost_Sure @miniapeur like the way u write a p? ρ I write like bro does in vid

Here’s an English mnemonic for π that’s always worked for me
“three point one four one five nine two six five”

@aryehazan @pli_cachete sorry, it is just a day. Feels like a week at least!
English
@Almost_Sure @pli_cachete geesh, it's been a day
patience my good man 😅

this sphinx has fallen
@pli_cachete has found a proof
it's gorgeous
stay tuned
Aryeh Kontorovich@aryehazan
perhaps the simplest-looking Sphinx inequality to date, still very challenging (I don't have a proof) @Almost_Sure @t0tientqu0tient ideas? (yes, I know -- find the right Markov kernel to apply data processing inequality. good luck)

tbf it’s exactly the same when Americans say Let’s do drinks/coffee sometime

An Arab tells you “you must come to my house for dinner.” You get excited. You wait for the invitation. It never comes. You think they were being fake. They weren’t. And not understanding this is one of the biggest mistakes expats make in the Arab world.

this could be useful if you’re running out of symbols to use in your maths

@heart_ That's nice. Here's a little aid from 1912:

@star_stufff @Kaju_Nut I saw a YT video recently working out how fast the surface would have to move if it was a rotating ball (and, yes, faster than light)
English
If it was a rotating ball
-- its surface would have to move faster than light
-- it could not return to its starting state after a full 360 degree rotation, only after a 720
and it would still get magnetic field wrong by a factor of 2.

it's funny because it's true 🤣

@DeGatchi Next steps
integral domains
Noetherian domains
Euclidean domains
Principal ideal domains
Unique factorization domains
Dedekind domains (here’s the real black magic)

@ElliotGlazer @plain_simon somewhere between 7 and 9

It’s that time of the year again. Please provide your current viewpoint regarding how many real numbers there are.

@miniapeur hockey is a game played in a field by schoolgirls. I guess boys can play it too, but usually they don’t.
Do you mean ice hockey?
English
@wtgowers @ElliotGlazer Not the full proof, just compress enough to be able to work it out
English
@wtgowers @ElliotGlazer Thing is, could the proof be compressed into 10000 bits, then we are just asking the value of each bit
English
Aliens reveal to Terry Tao a proof of the Riemann Hypothesis, which he understands. The rest of humanity gets to ask him 10,000 yes-or-no questions, which he'll answer to the best of his ability. How confident are you we would be able to prove RH within a year?

Please explain why you put in such an utterly strange sentence (this is kindergarten in China stuff). Thank you in advance.

@Almost_Sure @OneArmedBoh I'm thinking a dedicated face massage stick could potentially be sold for bone smashing purposes

A “facial massager” featured in a 1971 Montgomery Ward catalog was promoted as delivering a “gentle, penetrating massage.”
Priced at $4.99, it was marketed as a beauty tool designed to ease tension, boost circulation, and enhance the application of creams and lotions.
