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 first atomic bomb was tested on July 16,1945 at Alamogordo, New Mexico and was developed, constructed and tested by the Manhattan Project. The new device represented a completely new type of explosion. All explosives before this time got their power for the rapid burning of a chemical compound like gunpowder. These bombs could only do a limited amount of damage. This new group of nuclear explosives involved getting energy sources from within the nucleus of the atom.
The Atomic Bomb: Effects on Hiroshima and Mankind The nuclear bomb was the most devastating weapon ever created by man. It was developed between 1942 and 1945 during the second World War. The project to build the worlds first atomic weapon was called The Manhattan Project. The nuclear bomb was based on the idea of splitting an atom to create energy, this is called fission. Three bombs were created, “Trinity”, “Little Boy”, and “Fat Man”.
The only two atoms suitable for fissioning are the uranium isotope U-235 and the plutonium isotope Pu-239 (Outlaw Labs). Fission occurs when a neutron, a subatomic particle with no electrical charge, strikes the nucleus of one of these isotopes and causes it to split apart. When the nucleus is split, a large amount of energy is produced, and more free neutrons are also released. These neutrons then in turn strike other atoms, which causes more energy to be released. If this process is repeated, a self-sustaining chain reaction will occur, and it is this chain reaction that causes the atomic bomb to have its destructive power (World Book, 1990).
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.
The Manhattan Project was established by the U.S. government in 1942 so the country could develop an atomic device. A team under the command of United States Army Brigadier General Leslie R. Groves designed and built the first atomic bombs, directed by J. Robert Oppenheimer. This type of bomb was first tested at Alamogordo, New Mexico, on July 16, 1945. The amount of energy that was released by this explosion alone was equivalent to twenty thousand tons of TNT. Many nations have tested nuclear devices, in the atmosphere, under the earth, and under the oceans.

The locations for the second bomb were Kokura, Kyoto, and Niigata. The bomb detonated over Nagasaki was a implosion device that was tested in the first nuclear detonation at Alamogordo, New Mexico in 1945. The radiochemical reaserch of the nuclear fallout and fireball formation measurements of the test was used to establish the yield of the Nagasaki bomb as twenty kilotons). The Hiroshima bomb was a gun-type device in which two sub-critical pieces of enriched uranium were propelled together to create the explosion.

On April 6, 1945 at about 8:15 AM, before air raid alarms could go off, little boy exploded. The temperature was estimated to reach over 1,000,000 degrees Celsius. This bomb initially killed about a hundred thousand people, then injured about the same amount, and that does not include how many it killed after the blast from exposure to the radiation. Two days after the first bomb was dropped the U.S.S.R declared war on Japan.
The hydrogen bomb, a thermonuclear weapon is an explosive device that creates its explosion by fusing two atoms together, to create a reaction similar to the processes that happens on the sun. The concept was first developed in 1952, during the cold war, and the bombs continually grew in destructive potential until the Tzar bomb, a 50 megaton bomb, that was detonated by the Soviets in 1961. The hydrogen bombs were unique to atomic bombs, because unlike the atomic bombs, hydrogen bombs had no conceivable limit to their size. This in turn made it possible for scientists to build as big as they wanted. The hydrogen bomb was a definite step up from the kiloton range of the atomic bombs.

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.
