Mathematical billiards has been a playground for various topics within geometry and dynamical systems for the last 100 years. In this talk, we give an introduction to mathematical billiards and explore the importance of counting collisions in a billiard system. We show that by simply following the laws of physics we can use a billiard system to produce the first NN digits of ππ for any natural number NN. If time allows, we will also cover some theorems regarding collisions in a billiard system.
