From an old project of mine, now ported to marimo: the classic Littlewood fractal. What happens if you sample the ±1 coefficients of Littlewood polynomials from a 1D Ising model at different temperatures?

Two threads on calcalus in non-integer dimensions and how it is used in Quantum Field Theory.

Part I : What are fractional dimensions?

Or why the dimension of your brain surface isn't 2, but somewhere between the surface of crumpled paper and cauliflower.

1729 was the number of the cab that G.H. Hardy took when he visited S. Ramanujan in the hospital.

Hardy thought it was a "dull number" and Ramanujan replied "it is a very interesting number. It is the smallest number expressible as the sum of two cubes in two different ways"

Does P=NP? It’s one of the most fundamental problems in computer science. But, what is P? What is NP? We explain in our complexity class primer: https://t.co/gy9u8AC2v1

(Io sono ovviamente felice del consenso sempre più diffuso verso la scienza e le sue possibilità. Però devo dirlo, le crociate contro gli "infedeli" sono esattamente l'opposto dello spirito scientifico, le lascerei all'ambito religioso se proprio non se ne può fare a meno.)

Every odd integer is the difference of 2 squares
Proof:
1) Pick an odd number
░░ ░░ ░░ ░░ ░░

2) Bend it in half
░░ ░░ ░░
░░
░░

3) Fill in the rest
░░ ░░ ░░
░░ ▓▓ ▓▓
░░ ▓▓ ▓▓

The odd nbr is the area difference of the big and small squares
