## Dr. Robbert Dijkgraaf - The End of Space and Time: The Mathematics of Black Holes and the Big Bang

This lecture was filmed at the 2017 National Math Festival in Washington, D.C. and features Dr. Robbert Dijkgraaf of the Institute for Advanced Study (IAS).

Einstein showed more than a century ago how his theory of relativity captures gravity and the evolution of the cosmos in the geometry of space and time. However these laws of the universe break down at the frontiers of science: at the Big Bang, where time begins, and inside black holes, where time stops. New mathematical ideas about quantum geometry suggest a structure even more fundamental than space and time.

Dr. Robbert Dijkgraaf, Director and Leon Levy Professor of the Institute for Advanced Study in Princeton, is a mathematical physicist who has made significant contributions to string theory and the advancement of science education. Dijkgraaf is President of the InterAcademy Partnership, past President of the Royal Netherlands Academy of Arts and Sciences, and a distinguished public policy adviser and advocate for science and the arts.
