Maths is Everywhere
The Bounce of the Superball by Professor John D. Barrow. The commercially available 'Superball' of hard rough rubber displays many counterintuitive properties which seem to violate Newton's laws of motion. We will see that the Superball can be understood but its behaviour is completely different to a billiard ball when it undergoes collisions with a wall. We will look also at some other unusual motions of swerving and spinning balls in sports. (from gresham.ac.uk)
