Videos from “The Universe Speaks in Numbers” , On May 29, the Institute hosted a celebration of The Universe Speaks in Numbers by frequent Director's Visitor Graham Farmelo in an event that brought together some of the world's foremost science communicators, including Nima Arkani-Hamed, Kyle Cranmer, Robbert Dijkgraaf (left), Freeman Dyson, Thomas Lam, Karen Uhlenbeck, Edward Witten (right), and Natalie Wolchover, for an afternoon of talks on the close relationship between math and physics. The day ended with a discussion between Witten and Dijkgraaf ranging from the gap between theory and experimentation to some of the outstanding questions in quantum gravity, quantum field theory, and number theory. Watch the videos.
