Ed Witten, Charles Simonyi Professor in the School of Natural Sciences, and Helmut Hofer, Professor in the School of Mathematics, along with Marc Lackenby, Martin R. Bridson, and Rahul Pandharipande, have co-authored *Lectures on Geometry *...

In 2016, Professor Nathan Seiberg celebrates his sixtieth birthday and reaches his twentieth year as a Professor at the Institute for Advanced Study. The conference celebrating these occasions was...

In 2006, Edward Witten, Charles Simonyi Professor in the School of Natural Sciences, cowrote with Anton Kapustin a 225-page paper, “Electric-Magnetic Duality and the Geometric Langlands Program,” on the relation of part of the...

Prospects in Theoretical Physics is summer program designed for graduate students and postdoctoral scholars considering a career in theoretical physics. First held by the School of Natural Sciences at the Institute for Advanced Study in the...

We felt like we were in uncharted territory: no mathematicians we knew had ever received grants of this magnitude before. Normally, mathematicians receive relatively small individual grants from the National Science Foundation. This sounded a bit scary . . . We turned to the Institute for Advanced Study as the place to foster innovation. As they say, the rest is history.

It is indeed an endless cycle of imagination and concentration, of divergence and convergence, of playing and thinking that determines the rhythm of science and scholarship. The Institute is devoted to creating and supporting these experiences and the resulting, often surprising, advancements in knowledge.

*On November 14, the Institute for Advanced Study announced the appointment of Robbert Dijkgraaf as its ninth Director, succeeding, as of July 1, 2012, Peter Goddard, who has served as Director since January 2004.*

The ancients thought that space and time were preexisting entities on which motion happens. Of course, this is also our naive intuition. According to Einstein’s theory of general relativity, we know that this is not true. Space and time are dynamical objects whose shape is modified by the bodies that move in it.

*In the twentieth century, mathematicians developed a deep theory of knots, which was revolutionized by the discovery of the Jones polynomial—a way to calculate a number for every knot—by Vaughan F. R. Jones in the early*...

The fundamental lemma has been described as a gross understatement. Says Andrew Wiles, a Visitor in the School of Mathematics and an Institute Trustee, “At first, it was thought to be a minor irritant, but it subsequently became clear that it was not a lemma but rather a central problem in the field.”

When Friedrich Hirzebruch was a Member in the School of Mathematics in 1954, his paper, "Some problems on differentiable and complex manifolds", was published in the *Annals of Mathematics*. In it he asked whether Chern numbers in...

Physicists have used Feynman diagrams as a tool for calculating scattering amplitudes that describe particle interactions for more than six decades. Their broad utility was due initially in large part to the seminal work of Freeman Dyson,...
