Fundamental Physics in the Twenty-first Century | Nima Arkani-Hamed

Nima Arkani-Hamed, Professor, School of Natural Sciences, Institute for Advanced Study http://www.ias.edu/people/faculty-and... In this talk, Nima Arkani-Hamed, Professor in the School of Natural Sciences, discusses the direction of fundamental physics in coming years and decades, including efforts to replace the concept of spacetime and understand how the macroscopic world is formed by microscopic quantum mechanical laws. A key influence in the search for answers will be a new "golden age of experiments." The lecture was part of the Institute for Advanced Study's celebration of its eightieth anniversary in 2010.
