Explore firsthand accounts of research and questions posed by IAS scientists and scholars. From art history to string theory, from moral anthropology to the long-term fate of the universe, contributions span the last decade to the research of today.

The idea of trespassing is basic to my thinking. Attempts to confine me to a specific area make me unhappy. When it seems that an idea can be verified in another field, then I am happy to venture in this direction. I believe this is a simple and...

One of the oldest subjects in mathematics is the study of Diophantine equations, i.e., the study of whole number (or fractional) solutions to polynomial equations. It remains one of the most active areas of mathematics today. Perhaps the most basic...

The Electronic Computer Project (ECP) that was based at the Institute from 1945 to 1957 produced one of the world’s first large computers, and the very first with a stored-program design. 

The project was led by IAS Professor John von Neumann, who...

Taking Theory to Traffic

The largest live autonomous vehicle traffic experiment ever conducted began the week of November 18, 2022, in Nashville, Tennessee. While this experiment used 4 miles of highway, 288 cameras, and an impressive command center, one of its most vital resources was equations on a blackboard. In front of one of these blackboards was Benedetto Piccoli, Visitor in the School of Mathematics.
