As you heard in the last episode, Oak Ridge National Laboratory is celebrating its 80^th anniversary. The lab was born out of the Manhattan Project, a top-secret mission that would bring an end to World War II with the production of the world’s first nuclear weapons. Clandestine sites across the country worked unique pieces of the puzzle that would become the atomic bomb. While sites in Oak Ridge, Tennessee, and Hanford, Washington, studied and produced the material for the weapons, scientists in Los Alamos, New Mexico, were focused on the design and assembly of the bomb. Those efforts in Los Alamos were led by renowned physicist J. Robert Oppenheimer – a name that should sound particularly familiar this summer. Oppenheimer was the Manhattan Project mastermind behind the atomic bomb, and now his story is the focus of a new blockbuster film based on the Pulitzer Prize-winning biography, “American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer,” by Kai Bird and Martin Sherwin. As part of the 80th celebration, Kai Bird recently visited ORNL and joined us for a discussion on the legacy of Oppenheimer and the Manhattan Project.
