TIMELINE of the Atomic Bomb.1942 May - Heisenberg and Dopel observe the first contemporaries of neutrons.December 2 - First nuclear chain reaction at Chicagos Stagg Field by Fermi. 1943 March 15 - Oppenheimer moves the break development to Los Alamos. 1944 imposing 26 - Bohr presents his memorandum on intentional control of nuclear weapons to Roosevelt.1945 January 20 - First Uranium-235 separated at Oak Ridge.July 16 - U.S. explodes first nuclear bomb, the Trinity test, at Alamogordo.August 6,9 - Atomic bombs dropped on Hiroshima and Nagasaki. (Blow)The atomic bomb gets its vigour from nuclear fission ( change integrityting) of the nuclei (core) of uranium or plutonium atoms. Albert Einstein explained how the fission of heavy atoms could produce energy released as dangerously high levels of agitate 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 amount of energy (E), fair to middling to this mass multiplied by the square of the speed of light (c).(Blow)A very small amount of matter is equivalent to a long 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 stiff particle to cause uranium fission. Only one neutron is needed to split an atom. When the atom fissions (splits), it splits into two smaller atoms which are most always hot and releases an enormous amount of energy and two or three neutrons. The neutrons released could indeed possibly hit other nuclei of uranium, which causes them to split in the same fashion. This is a chain reaction (a series of fissions).
