Werner Karl Heisenberg (/ ˈhaɪzənbɜːrɡ /; [ 2 ]German: [ˈvɛʁnɐ kaʁl ˈhaɪzn̩bɛʁk] ⓘ; 5 December 1901 – 1 February 1976) [ 3 ] was a German theoretical physicist, one of the main pioneers of the theory of quantum mechanics, and a principal scientist in the Nazi nuclear weapons program during World War II.
Heisenberg himself, in the transcript, said that, "quite honestly I have never worked it [the critical mass calculation for an atomic bomb] out as I never believed one could get pure [uranium-]235." A week after the bombing, Heisenberg had given a more formal lecture to his colleagues on the physics of the atomic bomb, which corrected many of ...
The Leipzig research group was led by Heisenberg until 1942 who in winter 1939/1940 reported on the possibilities and feasibility of energy extraction from uranium for a uranium reactor and nuclear bomb. After the report Heisenberg withdrew from practical experiments and left the execution of the experiments L-I, L-II, L-III and L-IV mostly up ...
June 23, 1942. Leipzig, Nazi Germany. Steam explosion and reactor fire. Leipzig L-IV experiment accident: Shortly after the Leipzig L-IV atomic pile – worked on by Werner Heisenberg and Robert Doepel – demonstrated Germany's first signs of neutron propagation, the device was checked for a possible heavy water leak.
Allied work on nuclear fission had been motivated by scientists, many of whom were refugees from Nazi Germany, who feared a German atomic bomb program was underway. The discovery of fission had taken place largely in Otto Hahn 's Berlin laboratory, and many scientists in the United States held the work of German scientists, especially Werner ...
Copenhagen. (play) Copenhagen is a play by Michael Frayn, based on an event that occurred in Copenhagen in 1941, a meeting between the physicists Niels Bohr and Werner Heisenberg, who had been Bohr's student. It premiered in London in 1998, at the National Theatre, running for more than 300 performances, starring David Burke (Niels Bohr), Sara ...
Heisenberg in 1933. Beyond Uncertainty: Heisenberg, Quantum Physics, and the Bomb is a biography of Werner Heisenberg by David C. Cassidy.Published by Bellevue Literary Press in 2009, the book is a sequel to Cassidy's 1992 biography, Uncertainty: the Life and Science of Werner Heisenberg and serves as an updated and popularized version of the work.
Karl-Heinz Höcker. Carl Friedrich Freiherr von Weizsäcker[a] (German: [kaʁl ˈfʁiːdʁɪç fɔn ˈvaɪtsɛkɐ] ⓘ; 28 June 1912 – 28 April 2007) was a German physicist and philosopher. He was the longest-living member of the team which performed nuclear research in Nazi Germany during the Second World War, under Werner Heisenberg 's ...
