Strange “S” in the Light

Unexpected discoveries are one of the joys of mathematics, even for amateurs. And computers help you make more of them, because computers make it easy to adjust variables or search faster and further through math-space than any unaided human ever could (on the downside, computers can make you lazy and blunt your intuition). Here’s an unexpected discovery I made using a computer in November 2020:

A distorted and dissected capital “S”


It’s a strange “S” that looks complex but is constructed very easily from three simple lines. And it’s a fractal, a shape that contains copies of itself at smaller and smaller scales:

We Can Circ It Out

It’s a pretty little problem to convert this triangular fractal…

…into its circular equivalent:

Sierpiński triangle as circle

But once you’ve circ’d it out, as it were, you can easily adapt the technique to fractals based on other polygons:
