In an exploration of this year's University of Washington's Common Book, "The Meaning of it All" by Richard Feynman, guest lecturer Persi Diaconis, mathematician and magician, discusses the connections between his work and Feynman's physics. What are the physics of coin tossing? What does it mean to be random? How can we use randomness to understand the world around us and how do you make decisions in the face of uncertainty? In this enlightening talk, Diaconis exposes how mathematical thinking makes the world come alive and how simple questions can unravel what we thought we knew.
