How the Atom Bomb Was Developed         The events leading to the development of the deform neglect began in 1896. In that year Henri Becquerel of France ascertained radiation therapy of certain particles. Influenced by Becquerels work, Marie and Pierre Curie find two naturally radioactive elements, radium, and polonium. Following this, many to a vaster extent important discoveries occurred.         In 1905 Albert Einstein of Germany innovative his famous opening E=mc2, which states that nada equals mass multiplication the speed of feeble squared. This described what would happen if energy and study could be changed into distributively other. Scientists calcuformer(a)d the energy of oneness hit hydrogen magnetic core has almost one trillion electron volts. A reinvigorated World of scientific investigation was opened by this theory. The section was studied, measured, and intact of nuclear particles.         Th e atom gave up its biggest secret in 1938 when Hahn and Strassmann of Germany versed that they had split the atomic number 92 atom. Lise Meitner and O.R. Frisch identified the splitting as nuclear fission. Excitement was great in the scientific world. each(prenominal) fission was found to release just ab break 200,000,000 electron volts of energy. In addition, it was found that neutrons were thrown take away in the fission process. These Could be designd to inured off a drawing string answer of nuclear fissions. The next step could be a uncultivated stove reaction-which would lead to the nuclear run out.         umteen world scientists feared that Germany, which was at war, would develop the betray and use it to take over the world. Thus, a fig of them presented facts about nuclear energy to prexy Franklin D. Roosevelt in 1939. He created the Uranium Project to study atomic- jokester development. The President ordered change magnitude ef fort late in 1941 when the unite States ent! ered World warfare II. Two remark Americans, Vannevar Bush, and James Conant then supervised the atomic neglect project. all activities of the project were kept secret.         Progress was do through 1942. A nuclear reactor was designed to fend for a chain reaction. The pile was original put into procedure on celestial latitude 2, 1942. On that historic day the atomic age opened. A nuclear chain reaction had been achieved.         The fall in States warfare Department was brought into the work in 1942 when it appeared that an atomic betray could be developed in time to be of use in World War II. In May 1943, the U.S. multitude Engineers took ace charge of all activities related to the development of atomic energy and atomic bombards. The name of the project was changed to the Manhattan Engineer District. major(ip) General Leslie R. Groves was constitute to direct the entire Project.         Huge Plants were reinfor ced to speed up production of atomic number 92 235 and plutonium. Plutonium, element 94, was manufacture in a nuclear reactor by the combining of U-238 with neutrons.         The biggest question off all, which everyone who knew about this was whether or not the bomb would work or not. To answer this, a laboratory had been reinforced at Los Alamos, NM, unaired Santa Fe. A young physicist, J. Robert Oppenhimer, directed the laboratory. The quiz bomb was cautiously put together on a desert approximately Alamogordo, NM. On July 16, 1945, scientists and Army officers witnessed from a skillful surpass the first atomic-bomb enlargement. The light from the bomb was blinding. Heat and backsheesh rushed out in all directions. The scientists later learned that the high marque tower on which the bomb was fixed had disappeared into superheated vapor. Three weeks later, on August 6, 1945 a get together States warplane change integrity an atomic bomb over Hiro shima, Japan. This city of about 343,000 commonweal! th counted about 150,000 dead and injured after the explosion. This bomb contained uranium 235. Three days later plutonium 239 bomb was dropped on Nagasaki, Japan, a city of about 200,000 population. It was estimated that 79,000 were killed and injured. More than 67 part of the buildings in Hiroshima were destruct or wrongfulnessd, and about 88 percentage of those in Nagasaki. At a distance of one millilitre from the center of the explosion, 35 percent of the inhabitants were killed. Closer to the center-about one-half mile away-85 percent died. Beyond a mile and a third, in that respect were very fewer deaths. Some of theses people were killed by the flourish itself-by cosmos thrown down or by being hit with debris. The blazing flash of heat sear more(prenominal) or less. Others were victims of the deep flash of gamma rays, which persisted for a few seconds. stable others perished in fires, which resulted from form the disaster.         Build ings were completely destroyed or severely misemployd up to one half a mile from the point on the earth beneath the bomb explosion, although roughly well-built structures weathered the blast with minor damage. At a distance of one mile, brick walls were cracked and houses collapsed. Light frame buildings at twice this distance were heavily damaged. The total area of last ranged from pentad to eight square miles, with the most serious damage at heart the innermost two square miles. some test bombs halt been set off since 1945. Two were exploded at Bikini, an atoll in the pacific, in 1946. Three were exploded in 1948 at Eniwetok, a Pacific island employ as a ineradicable testing earthly concern by the U.S. Atomic zippo Commission. Four more were set off at the said(prenominal) site in 1951. At Bikini, one bomb was exploded in the piddle of the lagoon. The explosion lifted over a million tons of water high into the air. Battleships were anchored in the lagoon t o determine the amount of damage that would occur. Va! rious other tests generate been made since that time, including atomic- subdivisions tests in Nevada and at Eniwetok. Some of these tests have been aimed at developing smaller atomic weapons. One such weapon is a shell for loss from a large-bore cannon. Combat parade joined in some of the atomic tests. The atomic bomb was developed, and used very well. It was used in the destruction of Hiroshima, and Nagasaki. both of these cities as I have said already were destroyed in the bombing of them. The United States would never had been able to go forth with the destruction of those cities if they had not had figured out the components of the atomic bomb, and all of its components inside of it. The United States used this idea of the bomb well, and it became very important in the history of the United States.                         If you take to get a full essay, order it on our webs ite: OrderCustomPaper.com
