Math Encounters: "The Biggest Secrets in the World: Everything We Know We Don’t Know" with Rogério Martins (7:00 pm)

The world is full of simple questions without answers; secrets for which only Mother Nature knows the answer.  Join Rogério Martins, mathematician and Portuguese TV star of Isto é Matemática (This is Mathematics) on a journey into the unknown.  Fold a map, observe a levitating chain, and see an odd tumbler toy floating in an aquarium.  But, no worries, because... this is math!  Special introduction by Portuguese Consul General in NYC, Maria de Fátima Mendes.
