Hahn's Fission Discovery: The Chemist Who Made the Atomic Bomb Inevitable documentary

Hahn's Fission Discovery: The Chemist Who Made the Atomic Bomb Inevitable documentary This documentary explores the pivotal scientific discovery of nuclear fission in Berlin 1938. At the Kaiser Wilhelm Institute, chemist Otto Hahn and his colleagues Lise Meitner and Fritz Strassmann were investigating uranium and radioactivity. Their work with the neutron led to the unexpected identification of barium, revealing that the atom had been split. This breakthrough in chemistry and nuclear physics set off a race to understand the chain reaction, culminating in the Roosevelt Letter co-signed by Albert Einstein. As World War Two raged, this knowledge led to the Manhattan Project and the atomic bomb, with devastating consequences for Hiroshima. We examine Hahn's controversial Nobel Prize, his time at Farm Hall, and the lasting legacy of nuclear energy, the Cold War, and the immense moral responsibility that forever changed our world. 0:00 - Intro & The Scientific Spark in 1938 Berlin 7:08 - The Kaiser Wilhelm Institute and Otto Hahn’s Early Research 14:16 - Political Turmoil and Mitner’s Imminent Departure 21:24 - Competing Labs and the Transuranic Race 28:32 - Fritz Strassmann’s Role and Ethical Stance 35:40 - The Barium Puzzle: Chemical Results vs. Physical Expectations 42:48 - Radical Discovery: The Atom is Split 49:56 - Hahn Writes to Mitner: The Cry for Explanation 57:04 - The Christmas Epiphany in Sweden 1:04:12 - Naming Fission and Proving it Experimentally 1:11:20 - The Chain Reaction and the Threat of a Bomb 1:18:28 - The Einstein Letter and Roosevelt's Involvement 1:25:36 - Hahn’s Guilt After Hiroshima 1:32:44 - The Nobel Prize Controversy and Mitner’s Exclusion 1:39:52 - Hahn’s Legacy and the Moral Weight of Discovery SOURCES Rhodes, R.
