*The Mathematics of Simple Things*

Very simple objects can yield great mathematical richness. Join Paul Zeitz as he describes the surprising (and mathematical!) fun you can have with items as simple as strips of paper, business cards, and even toothpicks.

Paul Zeitz is a Professor of Mathematics at the University of San Francisco, an International Math Olympiad participant and trainer, co-founder and Board Chairman of Proof School, co-founder of the San Francisco Math Circle, co-founder of the Bay Area Math Olympiad, and author of *The Art and Craft of Problem Solving*.

**This is an occasional series; each presentation explores different entertaining topics. Join Paul for one, or come to them all!**
