Thomas Mason’s Interview

Thomas (Thom) Mason is the President and CEO of Triad National Security, LLC and the director designate of Los Alamos National Laboratory. A condensed matter physicist, he previously served as the director of Oak Ridge National Laboratory from 2007-2017, and as Senior Vice President for Global Laboratory Operations at Battelle. In this interview, Mason describes some of the major scientific projects at Oak Ridge from the Manhattan Project to today, including the Spallation Neutron Source, nuclear reactor development, scientific computing, and nuclear nonproliferation efforts. He also explains why he believes that the science done at universities and national laboratories creates “a fertile ground” for innovation.

Spencer Weart’s Interview

Spencer Weart is a historian of science. Originally trained as a physicist, Weart served for many years as director of the Center for History of Physics of the American Institute of Physics (AIP) in College Park, Maryland. In this interview, Weart discusses the French nuclear program, starting with its origins with Marie and Pierre Curie. He examines the prominent role of their daughter, Irene, and her husband, Frédéric Joliot, who together won a Nobel Prize in 1935 for their discovery of artificial radioactivity. Irene and Frédéric’s work made enormous contributions to the development of nuclear physics during the late 1930s. Weart goes on to explain how, during World War II, key members of the French program became part of the Manhattan Project, as well as Joliot’s role in the French Resistance. He concludes with a discussion of the postwar nuclear program in France.
