Can a square be dissected into an odd number of equal-area triangles? In this episode of The Deep Dive, we trace Fred Richmond's 1965 challenge, Paul Minsky's 1970 resolution, and the surprising blend of geometry, number theory, and combinatorics—using p-adic absolute values and Sperner's lemma—to prove the puzzle impossible.
