Nuclear+Fission

====Nuclear Fission is the reaction when a nucleus of an unstable atom is splits spontaneously upon impact with another particle resulting in a strong release of energy. The reaction of fission can only be started by a neutral atomic particle called a neutron. Fission of heavy elements is called an exothermic reaction which releases large amounts energy in the form of kinetic and exothermic energy. Nuclear Fission is mostly used for atomic weapons of mass destruction and was witnessed first hand when the Americans dropped two on Hiroshima and Nagasaki and when the Russians tested their Tsar Bomb in Siberia.====
 * Introduction-**

An induced fission reaction. A slow-moving neutron is absorbed by a uranium-235 nucleus turning it briefly into a uranium-236 nucleus; this in turn splits into fast-moving lighter elements (fission products) and releases three free neutrons.

History-
Around 1911, New Zealander Lord Ernest Rutherford modeled an atom as the smallest particle in matter that could not be divided. Danish Physist Neils Bore, improved the model of the atom and depicted it as a mini solar system where the nucleus was constantly orbited by electrons and protons. It was concluded by scientists Marie Curie and Peirre Curie that the atom had a nucleus of protons and neutrons orbited by electrons. Albert Einstein confirmed that was the correct description of an atom. In 1917, Nuclear transmutation was accomplished by Ernest rutherford where he was able to make water by combining atoms of hydrogen and oxygen together. In 1938, German physist Otto Hahn showed that the new lighter elements were barium and others which were about half the mass of uranium, thereby demonstrating that __atomic fission had occurred__. This discovery quickly interested Hitler who spent an etimated over a third of Germany's GDP to scientific exploration of nuclear power. Hitler had occult beliefs that ancient Aryan civilizations used nuclear power. All Hitler wanted to do was to revive the power. Werner Heisenberg, who from April 1939 presided over the German nuclear energy project under the German Ordnance Office. Initially this was directed towards military applications, but by 1942 the military objective was abandoned as impractical. However, the existence of the German Uranverein project provided the main incentive for wartime development of the atomic bomb by Britain and the USA. Due to the cruelty the Third Reich had on its scientists (ex: Werner Von Braun), some defected to the Allies to help with their own nuclear project: the Manhattan Project. The Manhattan Project began in 1942 as a research and developmental program for the first atom bomb. media type="youtube" key="T6UujimddEc" height="326" width="363" align="right"media type="youtube" key="aLFliTyydSs" height="315" width="420" align="right"
