So why do colliding blocks compute pi? Colliding Blocks - Part 2 of 3

The video explores a physics problem involving two sliding blocks in an idealized world with no friction and perfectly elastic collisions. The surprising result is that the number of collisions corresponds to the digits of π. The video explains this phenomenon using phase space, conservation of energy and momentum, and geometric representations. It highlights the inscribed angle theorem and how it relates to the number of collisions. The video concludes by emphasizing the importance of phase space in translating dynamic problems into geometric ones.
