*Math Encounters*: "Primes and Zeros: A Million-Dollar Mystery" with Brian Conrey (4:00 pm)

**Due to the New Year holiday, the January Math Encounters will take place on Tuesday, January 7, instead of Wednesday, January 1.**

How can we quickly determine how many primes there are less than some huge number? The great mathematician Georg Friedrich Bernhard Riemann proposed a solution 160 years ago — but we still haven't been able to verify his hypothesis. Join mathematician Brian Conrey, founding Executive Director of the American Institute of Mathematics, as he shares some of the colorful history surrounding the world's greatest-ever math challenge.
