Math Encounters — Online:

"Fun with Fractals: Finding patterns in the chaos" with Sarah Koch

Wednesday, May 5 at 4:00 pm ET (New York)

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.

This is a live-streamed event.  Occasional video recordings are made available for a fee at
