How colliding blocks act like a beam of light...to compute pi: Colliding Blocks - Part 3 of 3

The video explores the intriguing connection between mirror illusions and mathematical problems, particularly focusing on the block collision puzzle and its surprising link to π. It delves into using coordinate planes to transform dynamic problems into geometric ones, drawing analogies between optics and kinematics. The video explains the importance of rescaling coordinates for better mathematical understanding and uses the concept of momentum conservation through dot products. Finally, it employs a light beam and mirror analogy to elegantly solve the block collision problem, emphasizing the value of changing perspectives.
