Nuclear Weapons

In the first decades of the 20th century, physics was revolutionised with developments in the ground of the nature of atoms. In 1898, cut physicists Pierre curie and Marie Curie had discovered that pitchblende, an ore of uranium, contained a substancewhich they named radiumthat emitted large amounts of radioactivity. This raise hopes among scientists and laymen that the divisions around us could contain tremendous amounts of unseen energy, postponement to be harnessed.
In 1934 the idea of chain reaction via neutron was proposed by Leó Szilárd, who patented the idea of the atomic bomb. The patent was assign by him to the Admiralty (the controlling organisation for Britains Royal Navy) in 1936, this sleight of hand beingness necessary to prevent wider publication of the idea, as an Admiralty patent could be covered by the Official Secrets Act. In a truly real sense, Szilárd was the father of the atomic bomb academically.
In 1934, French physicists Irène and Frédéric Joliot-Curie discovered that kitschy radioactivity could be induced in stable elements by bombarding them with alpha particles, and in the same year Italian physicist Enrico fermi reported similar results when bombarding uranium with neutrons.




In December 1938, the German chemists Otto Hahn and Fritz Strassmann sent a manuscript to Naturwissenschaften reporting they had detected the element barium after bombarding uranium with neutrons;[2] Lise Meitner and her nephew Otto Robert Frisch correctly interpreted these results as being nuclear fission.[3] Frisch confirmed this experimentally on January 13, 1939.[4]
blush before it was published, Meitners and Frischs interpretation of the work of Hahn and Strassmann cut through the Atlantic Ocean with Niels Bohr, who was to lecture at Princeton University. Isidor Isaac Rabi and Willis Lamb, two capital of South Carolina University physicists working at Princeton, heard the news and carried it back to Columbia. Rabi verbalize he told Fermi; Fermi gave credit to Lamb. Bohr...If you want to stay a full essay, order it on our website: Orderessay
