Off topic, but where should one start learning writing physical simulation?

Several years ago I ran into this project [0] and got overwhelmed even the algorithm can be written in 88 lines of C++. I realized that out of all CS topics, physical simulation is probably the one I knew the less (not saying I'm a compiler/database expert or something, but at least I've implemented a toy compiler and some basic data structures used in database. When it comes to physical simulation my bran just draws a blank.)

Rigid body simulations are much much simpler. There’s a siggraph course from 2001 [0] which is a bit of a dense read but it will bring you all the way up to a full blown rigid body simulation and understanding the math behind it too.

Very nice, but probably a bit too expensive to just hand out.

I knew a chap that had a similar hardware business card (I don't remember exactly what it did, but it wasn't as cool as this one).

I remember that his card was pretty scuffed up, and he insisted I give it back, after he handed it to me. Bit weird.
