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.

Math Encounters is a public presentation series celebrating the spectacular world of mathematics, presented by the Simons Foundation and the National Museum of Mathematics.
