Math Encounters: "Mathematical Models and Card Shuffles — An Exploration in Group Theory and Probability"

Wednesday, December 1 at 4:00 pm ET (New York)


How can ordinary playing cards lead us into an adventure in group theory?  What are the chances that an ordinary shuffle will result in a random ordering of cards?  Are seven shuffles really enough to thoroughly mix up a deck of cards?  Join Dan Rockmore, Dartmouth Professor of Mathematics, to investigate the math behind the shuffle.

Special introduction by Steve Strogatz, Cornell University Professor of Mathematics and MoMath's Distinguished Visiting Professor for the Public Dissemination of Mathematics.
