The whole development in the making of an atomic bomb was called the Manhattan Project. The first bomb was tested on July 16, 1945 in New Mexico. The end result was the dropping of two atomic bombs by the United States on Hiroshima. People had different opinions on the bomb, but they may have come to one conclusion had they known about the history of the atomic bomb, how it was created, and the effects the bomb had in the economy. The Germans tried to use this energy, as did the United States and Russia.
The Atomic Bomb The research for the first Atomic bomb took place in the United States, by a group of nuclear engineers; the name of this research was called, “The Manhattan Project”. On July 16, 1945, the detonation of the first atomic bomb was tested near Los Alamos, New Mexico. As the atomic bomb was detonated, it sent shock-waves across the globe, which demonstrated that nuclear power would forever change the meaning of war. To create a nuclear bomb, nuclear fission must occur. The process of nuclear fission was splitting the nucleus of an atom.
The fuel is usually either Uranium-235 or plutomium-239. Uranium-235 has an extra property that makes it useful for both nuclear power production and for nuclear bombs - it is one of the few materials that can undergo induced fission. If a neutron runs into a Uranium nucleus, the nucleus will absorb the neutron, become unstable and split immediately. As soon as the nucleus captures the neutron, it splits into two lighter atoms and throws off 2 or 3 new neutrons. These neutrons then hit other uranium atoms and a chain reaction is started.
British and US scientists concentrated on fission of U-235 which would lead to a new element of mass U-239 an atomic number of 94 in which would lead them to discover neptunium #93 and plutonium #94 which was based off the finding of the uranium element (“Outline History of Nuclear Energy” 1). Harnessing energy from this was the main intention in 1945 (“Outline History of Nuclear Energy” 1). The atomic bomb development most focused on through 1939 to 1945. The Manhattan Project was the creation and testing of the first atomic bomb, 1942-1945 (“Nuclear History Timeline” 1). The first atomic device was successfully tested in New Mexico on July 16, 1945 (“Outline History of Nuclear Energy” 1).
The first atomic bomb to ever be used against humanity was dropped on August 6th, 1945. On that day a new kind of war was invented. There were, of course, many events leading up to this catastrophe. Some would say it began as far back as when Democritus proposed the idea of an atom. Maybe the first step towards the atomic bomb was when Einstein sent his fabled letter to President Roosevelt.
The Germans discovered nuclear fission, which is the basis of the nuclear detonation, and Albert Einstein brought the theory to the United States (Alperovite 164). United States government applied the physics of nuclear fission/fusion in the 1942 Manhattan project during WWII to develop the atom bomb (Cochran). The Manhattan project was an attempt to create the atom bomb, the most powerful bomb of its time (Maddox 25). The United States finished the Manhattan Project before the Germans and on June 16, 1945 America detonated its first successful test in Trinity, New Mexico(Rhodes and Richard 88-93). Briliant lights and a massive mushroom clout that was an effect of the explosion was seen for miles around.
In 1945, uranium-235, pure enough for use in a bomb was produce and sent to Los Alamos, where it was made into a gun-type weapon. One small piece of Uranium-235, which was not big enough to hold a chain reaction itself, was fired at another small piece. This was done by means of a explosive charge, inside a cylinder shaped tube, which for... ... middle of paper ... ...he U.S. built thousands of atomic bombs, and different types of smaller of fission weapons. A much more powerful bomb, the Hydrogen Bomb, became the leader of the U.S. nuclear arsenal. In general, the Hydrogen Bomb was like an atomic bomb with a Hydrogen fuel.
When the neutrons hit the uranium atom, the atom splits apart releasing energy and more neutrons causing more atom separations, thus causing a nuclear reaction gone critical (Wisegeek.com). It wasn’t until 1945 when the atomic bomb was completed. There were many prototypes for the atomic bomb one of the methods used to create the atomic bomb was to use plutonium, an artificial element which is heavier then uranium 235. Plutonium is made when a uranium 238 atom, which cannot undergo nuclear fission, absorbs a stray neutron turning it into u-239, then decays into plutonium 239 (nuclearweaponarchive.org). The first atomic bomb was completed on July 16, 1945, it was tested in Alamogordo, New Mexico under the code name “Trinity” (Atom Central).

The plutonium bomb reached critical mass through an implosion-style detonation. With this method a sphere of plutonium is surrounded by explosives, which compress the inner sphere of plutonium to critical mass. The bomb dropped on Nagasaki and the famous Trinity test were all conducted using this type of bomb.
The leader of the Manhattan Project was U.S. Army Brigadier General Leslie R. Groves. His team, working in several locations but in large part at Los Alamos, New Mexico, under the direction of American physicist J. Robert Oppenheimer, designed and built the first atomic bombs. The first atomic explosion was conducted, as a test, at Alamogordo, New Mexico, on July 16, 1945. The energy released from this explosion was equivalent to that released by the detonation of 20,000 tons of TNT. Near the end of World War II, on August 6, 1945, the United States dropped the first atomic bomb on the Japanese city of Hiroshima.
