Delbarton alumnus James Owen Weatherall ’01 has been elected to the American Academy of Arts and Sciences for his contributions in the field of Philosophy of Physics. Election to the American Academy of Arts and Sciences is considered one of the highest honors in the United States, recognizing distinguished scholarship, leadership, and creativity. 

Weatherall is a physicist, mathematician, and philosopher and holds a permanent position as Chancellor's Professor at the University of California, Irvine with a primary appointment in the Department of Logic and Philosophy of Science and a courtesy appointment as Professor of Mathematics. He currently is Department Chair for Logic and Philosophy of Science. 

His most recent book is The Misinformation Age: How False Beliefs Spread, co-authored with his wife, philosopher Cailin O’Connor, and published in 2019 by Yale University Press, in which the authors use  network models to investigate how social factors contribute to the persistent spread of false beliefs, even when there is strong evidence indicating that those same beliefs often lead to poor outcomes.  His 2016 book Void: The Strange Physics of Nothing explores historical and conceptual ideas relating to the physics of nothing, from 17th century controversies about empty space to odd features of vacuum states in contemporary quantum field theory. His first book, The Physics of Wall Street, published in 2013, explains how, over the past hundred years, ideas have moved from physics into financial modeling. Amazon describes Weatherall's first book as "taking us from fin-de-siècle Paris to Rat Pack–era Las Vegas, from wartime government labs to Yippie communes on the Pacific coast, James Owen Weatherall shows how physicists successfully brought their science to bear on some of the thorniest problems in economics, from options pricing to bubbles."

Today, Weatherall’s academic research focuses on the conceptual and mathematical foundations of classical and quantum field theories, and he pursues serious side interests in category theory and the foundations of mathematics, atomic physics and quantum control, and in non-relativistic quantum theory. Weatherall and O'Connor  have twin daughters, Evenstar and Vera, and a son, James, "who is [truly] the 8th of his name." 

A Teaching Moment: The American Academy of Arts and Sciences

The American Academy of Arts and Sciences was founded in 1780 by John Adams, John Hancock, and 60 other scholar-patriots who recognized that the new republic would require institutions able to gather knowledge and advance learning in service to and for the public good. The Academy is a premier honorary society that acknowledges excellence across academia, arts, industry, and public policy, including over 250 Nobel and 60+ Pulitzer Prize winners. Election is by one’s peers. Individuals must be nominated and elected by current members, making it a distinction conferred by peers in their field. This recognition is typically achieved later in one’s career based on a lifetime’s body of work and contributions to their field. This year’s class of honorees will be inducted in a ceremony in Cambridge, MA in October 2026.

The Delbarton community salutes James Owen Weatherall '01 for his induction into the American Academy of Arts and Sciences at the tender age of 42.
