. This topic is the end-all be-all topic when it comes to collision
detection. It covers many different types of collision geometry and all the possible
permutations between them. Be warned that this topic has a large amount of math,
so you might want to make sure you are comfortable with the math in this topic
before picking it up.

. This blog covers several different topics, but the physics articles
are of particular note. Fielder covers topics including how to implement fourth-or-
der Runge-Kutta as well as angular dynamics and springs.
