PLAYING POOL WITH π

Explanation

This project shows a principle first shown by Gregory Galperin in his paper titled Playing Pool with π.
One block is moving towards another in a completely elastic system (obeys the law of conservation of
momentum and the law of conservation of kinetic energy). When one block is 'n' power of 100 times heavier
than the other, the number of collisions between the two blocks and the block and wall computes 'n' digits of π.
