"One of the greatest theoretical physicists of our time, Paul Steinhardt is extraordinary in terms of his range and depth. In this program he discusses two of his best known research projects: first, the theory of a cyclic universe; and second, his prediction and later actual discovery of an entity thought not to occur naturally, the quasicrystal. Both of these projects are changing our view of Nature. Paul Steinhardt, Ph.D., The Albert Einstein Professor in Science at Princeton University, and Director of the Princeton Center for Theoretical Science. Professor Steinhardt is a faculty member of both the Department of Physics and Department of Astrophysical Sciences at Princeton."
