p. 192. A new technology is developed
- Maxwell Irvine
‘A new technology is developed’ explains the process of nuclear fission and charts the development of nuclear weapons during the Second World War. In August 1939 a letter to President Roosevelt drafted by Leo Szilard and signed by Albert Einstein stressed the danger that Germany might develop a weapon of enormous destructive capacity. By September 1941, the USA had been drawn into the war, and in 1942 the Allies' nuclear research was coordinated under the directorship of the American physicist Robert Oppenheimer. The resulting weapons destroyed the Japanese city of Hiroshima and Nagasaki and effectively brought the Second World War to an end.
