Showing results for "Nuclear War" in Physics

J. Robert Oppenheimer was one of the iconic figures of the 20th century, a brilliant physicist who led the effort to build the atomic bomb but later confronted the moral consequences of scientific progress. When he proposed international controls over atomic materials, opposed the development of the hydrogen bomb, and criticized plans for a nuclear war, his ideas were anathema to powerful advocates of a massive nuclear buildup during the anti-Communist hysteria of the early 1950s.

The world is currently closer to superpower conflict than at any time since the 1962 Cuban Missile Crisis. World War III is a real possibility, and with 12,000 warheads in the arsenals of more than half a dozen countries, we are standing on a nuclear knife edge. Despite receiving very little attention, nuclear war is a far greater threat to humanity's immediate survival than climate change. While climate heating threatens humanity over many decades, nuclear war could destroy civilisation in just a few hours.

The justification for the atomic bomb was simple: it would defeat Hitler and end the Second World War faster, saving lives. The reality was different. Fallout dismantles the conventional story of why the atom bomb was built. Peter Watson has found new documents showing that long before the...

Drawing on troves of declassified files, including records released by the government for the first time through the author's efforts, Restricted Data traces the complex evolution of the US nuclear secrecy regime from the first whisper of the atomic bomb through the mounting tensions of the Cold War and into the early 21st century. A compelling history of powerful ideas at war, it tells a story that feels distinctly American: rich, sprawling, and built on the conflict between high-minded idealism and ugly, fearful power.

After a devastating run of German victories, Allied troops are beginning to halt Hitler’s advance. But far from the battlefields, Allied scientists are struggling. Intelligence reports put them a distant second behind the Germans in a competition that could determine the outcome of the war: the race to build the world’s first nuclear weapon. For the Allies’ top scientists, the race is deeply personal. J. Robert Oppenheimer, Enrico Fermi, and Samuel Goudsmit have known Hitler’s chief atomic scientist, Werner Heisenberg, for years.
