The story of the atomic age began decades before Robert Oppenheimer watched a mushroom cloud form over the New Mexico desert at the Trinity nuclear test in mid 1945. It begins in 1895, with Henri Becquerel’s accidental discovery of radioactivity, setting in motion a series of remarkable and horrifying events. By the early 20th century, a brilliant group of scientists—including Ernest Rutherford, Leo Szilard, Enrico Fermi, and others—were pushing the boundaries of knowledge, seeking to answer fundamental questions about this source of energy that had 2 million times the energy density of oil: What is this mysterious radiation? Could it provide an infinite energy source, where a basketball of it was equal to an oil field? And, ominously, could it be weaponized?

Today’s guest is nuclear physicist Frank Close, author of “Destroyer of Worlds: The Deep History of the Nuclear Age.” We look at the complete history of the atomic age, from the initial curiosity about radioactivity to the creation of the hydrogen bomb—a weapon of almost unimaginable destructive potential, capable of eradicating life on Earth. This is an account of the scientific discoveries that unlocked the atom’s power, the ethical dilemmas faced by scientists, and the horrifying realization that this newfound energy could lead to humanity’s undoing.
