There's been a buzz - mostly from Tech Bros - about AI getting gold medals in the International #Mathematics Olympiad, including a remark "Now this *is* impressive". No it isn't, here's why...

TL;DR computers aren't human. Shocking, I know. 😂 The standards are established based on what's reasonable for humans to achieve in #Maths. Humans have limited ability to think, and fallible memory. In contrast computers have vast amounts of processing power and infallible memory...

Tiens, j'ai une question pour la team #maths et théorie des cardinaux. On suppose l'axiome du choix et l'hypothèse du continu, donc tout intervalle réel a pour cardinal aleph_1.
Je prend l'intervalle [0,1]. Je peux lui mettre un bon ordre dessus, en vertu de l'axiome du choix/théorème du bon ordre de Zermelo. A priori, je sais rien de ce bon ordre. Tout ce que je sais, c'est que pour tout nombre x, le segment initial ayant pour extrêmité x est dénombrable (enfin, de cardinal fini ou aleph_0). Donc pour tout x, la mesure de Lebesgues de de l'ensemble des nombres plus petits que x est de mesure nulle. Vous le voyez arriver le problème ?
Si je prends deux nombres au hasard, la probablilité que chacun soit plus petit que l'autre est 0. Enfin, à condition qu'un certain ensemble soit mesurable, mais je suis pas sûr de mettre le doigt dessus : l'ensembles des paires (x,y) telles que x soit plus petit que y ?

**Math Is Erotic**

"_The purely mental activity of doing mathematics can be a mode of access to something that transcends the human mind. That this should be the case would seem to indicate that there is a deep resonance between mind and cosmos—almost as if cosmos participates in mind._"

A neat little trig relationship arose in class today.

In answering a question some students "panicked" and chucked it into "solve" in their TI Nspire graphics calculator (let's not get distracted by my hatred of such tech) and as part of the solution got:

π/2 - arctan(1/10)

Whereas if one did it (very simply) by hand, this term was:

arctan(10)

One hopes anyone marking this would understand they're the same, but it baffled the students... queue learning moment. 1/n

_By age 16, “being on some occasion made ashamed of my ignorance in figures, which I had twice failed in learning when at school,” Franklin continued, “I took Cocker’s book of arithmetic and went through the whole by myself with great ease.”_

#TIL, that books† that teach Proof Writing are the Wren and Martin / Strunk and White of the #Maths world. Tactical knowledge that makes everything else easier.

WHY THE HELL DID NO ONE TELL ME THIS BEFORE?!
I would have started my Maths self study journey so much sooner 😂
