Math Encounters: "Hidden Patterns: the shape of multiplication" with Federico Ardila Mantilla on September 7, 2022

You probably had to memorize the multiplication table at some point in your life, but you may not have noticed that there are two beautiful shapes hiding within. Join mathematician Federico Ardila Mantilla as he helps us discover these hidden polyhedra and shares some other unexpected places where they also — surprisingly — appear.

Special introduction by Daniel Alarcón, novelist, journalist, radio producer, and professor at the Columbia Journalism School.

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