The Good ol' Atom Bomb

1. The OLD Eldred Nelson and Stanley Frankel went to Los Alamos in the spring of 1943 to begin working on make the atom bomb. They used the same desk calculators,Marchant and Friden, that they used in the Radiation Laboratory at the University of California, Berkeleyto to make the calculations required in the design of nuclear weapons. These mechanical calculators tended to break easily when they being heavy used, and would be shipped back to the manufacturer until physicists Richard Feynman learned to repair them. Then they switched to the use of the IBM punched-card machines which were use for the calculations to simulate implosion. Brief History • The creation of the atomic bomb starts with the "The Manhattan Project" when Albert Einstein wrote to President Franklin D. Roosevelt, on August 2, 1939, that Nazi Germany were trying t to purify uranium-235, which is the key element in the Atom Bomb. • “The Gadget”, the first Atom bomb to be tested, dropped in northern New Mexico on July 16, 1945 starts the Atomic Age. • “Little Boy” dropped on Hiroshima on August 6, 1945 by the US, being the first Atom bomb used in war. • “Fat Man”, the second and last Atom bomb use in warfare, was dropped on Nagasaki on August 9, 1945 by the US. The Good ol' Atom Bomb The NEW The PEAC software was designed from the result of Hiroshima and Nagasaki to calculate the theretical result of any size atom bomb at any time.
