The video explores a mathematical puzzle involving a room with mirrored walls and a laser that can bounce indefinitely. The challenge is to determine the minimum number of blockers needed to ensure safety from the laser. The solution involves using reflections to transform the problem into a linear path problem, ultimately requiring 16 blockers to guarantee safety. The video also acknowledges contributions from mathematicians Peter Winkler and Martin Gardner.
