General Math and Physics
The things here either don't fit in the other sections or they so largely encapsulate more than one section that putting them there wouldn't do the material justice.
- 3Blue1Brown's differential equation series: Rudimentary look at vector fields, ODEs, and PDEs.
- 3D Math Primer for Graphics and Game Development: Free online book for game math.
- Improved Collision detection and Response by Kasper Faubery: Includes C++ code.
