About Parixai

Free games and lessons that teach physics, AI and more from first principles, for anyone curious about how things work.

Why games?

People remember what they figure out themselves. Each game turns one idea into something you can poke at: change the angle, change the planet, see what happens. The lessons come after, when you already have a feel for the answer, and they build up from the simplest ideas so that nothing is taken on trust.

If we add visitor counts later, we will use a cookieless analytics tool that counts page views without identifying anyone, and update this page first.
