I got told to introduce myself here... So, hi! I'm a games programmer with an occasional need to implement unusual physics things. Working on racing games currently. I have a maths A-level, and a degree in Computer Games Technology which included a fair bit of dynamics and other reasonably advanced mathsy things, but that was all 15 years ago and I've forgotten most of it. I'm likely to ask questions about how to fake things semi-convincingly, rather than how to build precise and accurate physical models.
