TIMELINE of the Atomic Bomb.1942 May - Heisenberg and Dopel observe the first multiplication of neutrons.December 2 - First nuclear chain chemical reaction at Chicagos Stagg Field by Fermi. 1943 March 15 - Oppenheimer moves the bomb development to Los Alamos. 1944 August 26 - Bohr presents his memo on intentional control of nuclear weapons to Roosevelt.1945 January 20 - First Uranium-235 disordered at Oak Ridge.July 16 - U.S. explodes first atomic bomb, the Trinity test, at Alamogordo.August 6,9 - Atomic bombs dropped on Hiroshima and Nagasaki. (Blow)The atomic bomb gets its energy from nuclear fission (splitting) of the nuclei (core) of uranium or plutonium atoms. Albert Einstein explained how the fission of heavy atoms could bring forth energy released as dangerously high levels of heat and radiation. He published his theory in 1905 which is the well-known equation E = m c-squared. This states that a given mass (m), is associated with an inwardness of energy (E),equal to this mass cipher by the square of the speed of light (c).(Blow)A very humbled amount of matter is identical to a vast amount of energy. For example, 1 kg of matter converted completely into energy would be equivalent to the energy released by exploding 22 megatons of TNT. The neutron is the most effective particle to consume uranium fission. Only one neutron is needed to split an atom. When the atom fissions (splits), it splits into cardinal smaller atoms which are most always radioactive and releases an enormous amount of energy and two or three neutrons. The neutrons released could then possibly bear on other nuclei of uranium, which causes them to split in the same fashion. This is a chain reaction (a series of fissions).
