Physics Colloquium - Christy Lecture

Today's nuclear arsenals pose enormous risks for all humanity. Many agreements that reduced the threat of nuclear weapons have been abandoned and we now face a new, multi-country nuclear arms race that could have devastating consequences. Enormous resources are being expended by the United States, Russia, China, and North Korea to deploy new nuclear weapons and nuclear-armed long-range missiles. New countries are considering acquiring nuclear weapons. The war in Ukraine and other factors have increased the threat they might be used. In past times of danger, scientists and especially physicists have played a critical role in helping citizens and decision makers understand and reduce the threat posed by nuclear weapons, and they can do so again. I will describe a project initiated by the American Physical Society to inform, engage, and mobilize physical scientists and engineers to act now to reduce the current nuclear threat.

Speaker Bio: Frederick Lamb is a Research Professor of Physics and of Astronomy, the Brand and Monica Fortner Chair of Theoretical Astrophysics Emeritus, and a core faculty member in the Program in Arms Control and Domestic & International Security at the University of Illinois. An expert on space policy, ballistic missiles and missile defenses, and the technical aspects of nuclear test bans, he has been a consultant to the Defense Department, national laboratories, and Congressional committees. He co-chaired the American Physical Society's 2003 study of Boost-Phase Missile Defense and chaired its 2025 study of Strategic Ballistic Missile Defense. The current focus of his scientific research is high-energy and relativistic astrophysics and dense matter. He is a Member of the American Academy of Arts and Sciences and a Fellow of the APS. Among other awards, he shared the 2005 Leo Szilard Award of the APS for his leadership of the 2003 study of missile defense and the 2022 Bruno Rossi Prize of the American Astronomical Society for his contributions to the success of NASA's NICER X-ray astronomy mission.
