Converting elliptic curves between Weierstrass, Montgomery, and twisted Edwards form. Using Baby Jubjub and Tiny Jubjub as examples.

A prime number that looks like a blackand-white image of an American flag when written in a block.

Python integers can be arbitrarily long, but there are limits on the size of string that you can convert to an integer. How to get around this limit.

A simple random process that produces the Twin Dragon fractal.

If you remember the words in a seed phrase out of order, try permutations in order of their permutation distance from what you remember.

An ingenious device for factoring integers from the days before computers. A set of around 300 stencils could factor 9-digit numbers.

Creating interesting images by connecting the partial sums of a series involving the exponential of complex numbers.

When does log x equal x with the decimal place moved? First we look at the problem for base 10, then for more general bases.

A general recipe for creating randomly-generated fractals that tile the plane.

Knuth defines the twindragon fractal to be the set of complex numbers that are "fractions" in base 1-i. Implemented in Python code.

Pick's theorem computes the area of a figure drawn on a grid by counting the number of grid points inside and on the perimeter, but the formula isn't obvious.

Variations on Knuth's twindragon fractal by rotating the base.
