Paul's blog@Wildbunny - Physics engines for dummies
"This time i’m going to talk about the basic components that make up a physics engine and how to put them together; this tutorial is aimed at programmers who have a basic grasp of maths and geometry but would like to step into the world of simulation.
It is my hope that if, at the beginning of this article, you are able to code the physics behind the 1972 game Pong, by the end of the article you will be equally happy writing your own constraints to use in your own physics solver!

A pretty cool article and tutorial about physics engines and gaming.
Note that while there's a good bit of source in the article, the complete source for the article (ActionScript) is available for purchase only ($3.99). I'm not sure how I feel about that. I can TOTALLY see that a great deal of work went into this post and that free isn't free. Also everyone has to pay the mortgage. Also there's enough "free" information in the article that paying for this source is more of a thank you to the author than anything. Still, it's not something you see often and I think it pretty bold and thought provoking move...
