Abstract: Who doesn’t like one of these three: geometry, topology, and combinatorics? 
And even if you don’t, you will still love Sperner’s lemma, which is a combinatorial 
statement that is equivalent to the Brouwer fixed point theorem in topology. I’ll 
explain what it is, why it’s so amazing, give heartwarming old and new proofs, and 
present a recent generalization tio polytopes that has surprised me with diverse 
applications: to the study of triangulations, to fair division problems, and the 
Game of Hex.
