### Quick journey into physics

I'm quite good at maths but I always sucked at physics. I can simulate simple particle systems, and have a decent knowledge into fluid dynamics, even if not enough to truly understand it. Electromagnetism is magic to me and I didn't know how to simulate constrained rigid bodies. As the game I've almost finished relies heavily on physics, I decided to go and find some tutorials on rigid body simulation for games. The following is a list of what I've found useful, in the order it should be read:

12. more to come... suggestions appreciated (especially good tutorials on solvers of the Lagrange multiplier constraits, PGS and sequential impulses, and simple tutorials of the reduced coordinates approach)
