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.

Past Members in the School of Natural SciencesRobert J. Vanderbei (2019–20) and Michael A. Strauss (1991–95), along with Neil deGrasse Tyson and J. Richard Gott, have authored a unique journey into the cosmos titled Welcome to the Universe in 3D: A Visual Tour, the fourth in a series of astrophysical tours for Princeton University Press

In colloquial speech the word “duality” connotes two contrasting facets of a single entity, often at odds with one another. The concept is anthropomorphized in mythology by deities or monsters with multiple faces, like the two-faced Janus, Roman god of doorways. It is also enshrined in pop culture in the double visages of Jekyll and Hyde, and in the Batman villain Harvey Dent (alias Two-Face). In physics and mathematics, the concept of “duality” takes on a more positive connotation because of its ubiquity, utility, and power. 

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.

Rediscovering One of the Institute's First Women of Color

In the Spring 2023 edition of The Institute Letter, archivist Caitlin Rizzo outlined her research into Thayyoor K. Radha, one of the earliest women of color at the Institute. Radha joined IAS in 1965–66 as a Member, but her continued success was rendered virtually undiscoverable after her marriage saw her change her surname. After reading The Institute Letter, Radha’s daughter reached out to the Archive, allowing more elements of her story to be collected.

The Curriculum of the Woods

Predicting thousands of years of forest growth with just an afternoon of fieldwork and a simple calculator might seem like an impossible task, but Jonathan Levine, Chair of Princeton’s Department of Ecology & Evolutionary Biology, who runs annual classes in “Forest Succession” in the Institute Woods, enables his students to achieve precisely this.
