Math Encounters — Online:
"Bouncing Billiards: The Symmetries and Mathematics in the Path of a Rolling Ball" with Diana Davis
Wednesday, February 3 at 4:00 pm ET (New York)
If you hit a ball on a pool table, it will bounce around for a while — it might even return to where it started and repeat its path. It turns out that these periodic trajectories are very beautiful, forming a unique kind of mathematical art. Join Dr. Diana Davis, Phillips Exeter Academy Instructor in Mathematics, as she shares an amazing array of images, discusses how she and her colleagues figured out how to draw these intricate paths, and reveals some surprising properties — buddies, families, and symmetry — that they discovered along the way.
Special introduction by Amie Wilkinson, Professor of Mathematics, University of Chicago.
Purchase "math is beautiful" earrings created by Diana at Additions, the shop at MoMath.
