Crazy-good animations and diagrams of mathematical and physical topics. He likes to use a home brew programming setup using PHP, GD, and the free raytracer POV-Ray. I think I need to revisit GD.

This Thing For Which We Have No Name |
A good read. He argues that capitalism is anything but rational -- indeed a purely rational actor(s) would quickly become predictable and be gamed. He argues that we go to McDonald's in a foreign country because it provides a guarantee of not being completely awful, that is it "satifices" -- a word he made up. He asserts (and I concur) that neoclassical economists created an imaginary species, "homo economicus" just so they could mathematically model it.

Very good article, at least the portion I've read. Covers topics such as what is a personality, limits of imagination, how loss of memory with age affects identity--when does a person stop being the same person? Just good stuff.
