Maths for Divers

I started out from school doing maths because that was what I was good at but at university became infatuated with the physics side of the course and ended up doing mostly physics options. Somehow I have ended up doing computers because everything is computers but my sort of computers are for instruments and machine control because that's fun.
So when I took to scuba diving the engineer in me wanted to know what was going on and the mathematician wanted to know how to calculate it.
