Ep 58S4 E4: 70 Years of Atoms for Peace

70 years ago, President Dwight D. Eisenhower went before the United Nations and delivered a speech unlike anything the world had ever heard. The president spoke in sweeping terms about the terrible destructive power of new atomic weapons. But he also had a message for the assembly, one with a more optimistic tone: Join us in harnessing the power of the atom for good — not evil. From the dawn of the atomic age, nuclear power branched into two distinct paths: nuclear energy, and nuclear weapons. A chain reaction of historical events would lead down one path to the creation and eventual detonation of the world’s first atomic weapons in 1945. Down the other path, work forged ahead on peaceful uses of nuclear power. Join us on a trip through nuclear history, from "Atoms for Peace" to today.
