How did the most powerful force in history begin with a faint smudge on a photographic plate?

In this episode, Adam McCauley speaks to physicist and award-winning science writer Frank Close about his new history of the development of nuclear power and the extraordinary minds behind it.

Beginning with Henri Becquerel’s accidental discovery in 1896 Paris, Close explores the unlikely origins of the nuclear age through the chain reaction of scientific breakthroughs and personal obsessions that set the stage for the splitting of the atom. It is the ultimate story of how pursuit of this hidden source of nuclear power, which began innocently and collaboratively, was overwhelmed by the politics of the 1930s, and following devastation of Hiroshima and Nagasaki opened the way to a still more terrible possibility: a thermonuclear bomb, the so-called “backyard weapon”, that could destroy all life on earth – from anywhere.

Frank Close is a Fellow of the Royal Society, Professor Emeritus of Theoretical Physics at Oxford University and Fellow Emeritus in Physics at Exeter College, Oxford. His new book is Destroyer of Worlds: The Deep History of the Nuclear Age: 1895-1965.
