The math has been around for decades - but nobody noticed it gives a new framework for quantum mechanics from which the Standard Model gauge group and its representation on one generation of quarks and leptons falls out pretty naturally:

I will probably explain this in a bit, but I'm still recovering from writing the paper! We sprinted to finish it in time for our

Wow! If the side length of this "Sierpiński triangle" is 1, the average distance between its points is 466/885.
Double wow! The average number of moves in a shortest path between two random states in the n-disc Tower of Hanoi puzzle is asymptotically (466/885)·2ⁿ as n → ∞.

BUT, we now have much nicer counterexamples to the Jacobian Conjecture than the one originally found by Fable on July 19th. It took just a day.
If the math here makes no sense, try the explanation here:

Why do paths through the nth approximation to the Sierpiński triangle correspond to allowed sequences of moves in the n-disc Tower of Hanoi?
Well, suppose you have 3 discs. Draw the allowed states of the Tower of Hanoi puzzle as below. For example, (3,2,1) means "biggest disc on post 1, second biggest on post 2, third biggest on post 3". Draw edges for allowed moves between states. You get

Someone on Bluesky asked what's the relevance to quantum field theory.
The first step is to find polynomials P with E[Pⁿ] = 0. After some thinking we notice P(x,y) = x + iy has this property, and indeed the Gaussian Moments Conjecture hol…
The Gaussian Moments Conjecture is a pretty conjecture connected to probability and quantum field theory. Two days ago we suddenly learned it's false! - since it implies the Jacobian conjecture.
Let me explain this conjecture - it's very…

But suppose we measure distance between points in the plane in the usual way. What's the average distance between two points in the Sierpiński triangle with side length 1? I'm getting
0.4226884 ± 0.00004
This is close to 41/(56√3). B…
But be careful:
By "distance", I mean the length of the shortest path moving inside the Sierpiński triangle, not the usual distance between points in the plane.
Also: we compute the "average" distance using the natural measure on the Si…

The exceptional groups E₈, E₇ and E₆ are famous - but in fact we can define Eₙ groups for smaller n too. E₃ is the gauge group of the Standard Model! Some larger ones are gauge groups of famous grand unified theories. I used to think …
