It is a well-loved fact that each closed connected surface is homeomorphic to either the sphere, a connect sum of tori, or a connect sum of real projective planes.  This has been known since the 1860's.  In the early 1990's, Conway developed what he called the "Zero Irrelevancy Proof" (ZIP).  This talk will cover Conway's proof.
