30. The Impossible Bomb: The Hidden History of British Scientists and the Race to Create an Atomic Weapon
Henge

The remarkable story of the forgotten British scientists who enabled the Manhattan Project to create the atomic bomb. In this gripping talk, Gareth Williams uncovers the crucial, often overlooked role played by British scientists in the race to build the world’s first nuclear weapon. Working in secrecy under the codename ‘Tube Alloys,’ a remarkable group of physicists, many of them refugees from Nazi Europe, grappled with the terrifying possibility of a bomb capable of destroying entire cities. Their ideas, persistence, and breakthroughs would prove vital to the success of the wider Allied effort. Blending science, espionage, and high-stakes wartime politics, this is a fascinating story of innovation under pressure, and a sobering look at how one of humanity’s most devastating inventions came into being.
