Math Encounters: "Navigating with Golden Rotations" with Peter Sarnak on November 3, 2021

Join Princeton University Professor of Mathematics Peter Sarnak in an exploration of some of the subtle features enjoyed by rotations in two- and three-dimensional space, from paradoxical decompositions to optimally efficient universal quantum gates. Special introduction by Dr. Terrence Blackman, Associate Professor of Mathematics, Medgar Evers College, CUNY.

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

$Math Encounters: Fun with Fractals: Finding patterns in the chaos— S. Koch A dynamical system pairs a set with a rule that transforms the set. Applying the rule over and over, or iterating the rule, often leads to remarkably beautiful objects that are called fractals. Join mathematician Sarah Koch in an exploration of different kinds of dynamical systems and the fractals that emerge from each. Along the way, meet many famous fractals including the Cantor set, the Sierpinski triangle, the Koch Snowflake, and several entertaining Julia sets. Special introduction by Dr. John H. Hubbard, Professor of Mathematics, Cornell University.
