Event description: 
In this talk I will explain my recent solution of the Halpern-Weaver Conjecture.  The result is that a strip of paper that is 1 unit wide must be more than sqrt(3) units long in order for it to be smoothly folded into a paper Moebius band, and this bound is sharp. The proof is elemetary enough that I can explain the whole thing during the talk.  I’ll also talk about lots of related unsolved problems.
