Jordan Ellenberg with Peggy Pfeiffer and guest host Dr. Erica Litke

A great addition to the Arts Pod, mathematician and author Jordan Ellenberg calculates the multiplicity of areas covered by his mentor, Peggy Pfeiffer, who combined various factors to create a writers salon in their high school. We can only discuss a fraction of their infinite knowledge, but we divide and conquer hosting duties with Dr. Erica Litke, associate professor of mathematics education in the College of Education & Human Development at the University of Delaware. JORDAN ELLENBERG is the John D. MacArthur Professor of Mathematics at the University of Wisconsin-Madison. His research centers on number theory and arithmetic geometry. He is also the author of the New York Times bestsellers How Not To Be Wrong and Shape, the decidedly non-bestselling novel The Grasshopper King, and articles on mathematical topics for The New York Times, The Washington Post, and many other newspapers and magazines.
