Today’s Google doodle honors mathematician Benoit Mandelbrot. He would have been 96 today. If you’re interested in learning more about his life and work, the Google doodle link contains a short summary. If you want to go deeper, you can read the Wikipedia article on him.
I only have one small thing to add. A few years ago I wrote an interactive text-based game, A Beauty Cold and Austere. You can read some reviews of it and play it here, and you can read some of my thoughts about it here. The connection to Mandelbrot is that I used part of the Mandelbrot set for the cover art for the game, as you can see below.
