In the first part of our 80th anniversary series, you heard how the Manhattan Project helped end World War II with the development and use of the world’s first nuclear weapons. The success of this top-secret endeavor ushered in a new era of nuclear science. The expertise used to build the atomic bombs was applied in peacetime to a range of nuclear-inspired research. This research would spawn significant advances in existing fields like chemistry and materials science, and establish completely new ones like neutron scattering and health physics. In this episode, we'll explore the lab's growth and evolution in the decades that followed the war.
