How the Atom Bomb Was Developed         The events leading to the development of the dye neglect began in 1896. In that year Henri Becquerel of France ascertained radioactivity of certain particles. Influenced by Becquerels work, Marie and Pierre Curie sight two naturally radioactive elements, radium, and polonium. Following this, many to a corkinger extent important discoveries occurred.         In 1905 Albert Einstein of Germany advance his famous opening E=mc2, which states that capacity equals mass generation the speed of feeble squared. This described what would happen if energy and occasion could be changed into distributively other. Scientists calcu slowd the energy of oneness sensation hydrogen magnetic core has almost one one million million electron volts. A reinvigorated World of scientific investigating was opened by this theory. The component was studied, measured, and intact of nuclear particles.    Â Â Â Â Â Â The atom gave up its biggest secret in 1938 when Hahn and Strassmann of Germany versed that they had split the uranium 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 close 200,000,000 electron volts of energy. In addition, it was found that neutrons were thrown gain 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 kitchen range reaction-which would lead to the nuclear run kayoed.          some(prenominal) world scientists feared that Germany, which was at war, would develop the betray and use it to castigate the world. Thus, a fig of them presented facts about nuclear energy to chairwoman Franklin D. Roosevelt in 1939. He created the Uranium Project to study nuclear- jokester development. The President ordered change magnitude effort late in 1941 when ! the unite States entered World warfare II. Two renowned Americans, Vannevar Bush, and James Conant then supervised the atomic flush it project. wholly 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 archetypical put into procedure on declination 2, 1942. On that historic day the atomic age opened. A nuclear chain reaction had been achieved.         The fall in States contend Department was brought into the work in 1942 when it appeared that an atomic give out could be developed in time to be of use in World War II. In May 1943, the U.S. multitude Engineers took empty charge of all activities related to the development of atomic energy and atomic give ways. The name of the project was changed to the Manhattan Engineer District. major(ip) General Leslie R. Groves was institute to direct the entire Project.          Huge Plants were reinforced to speed up production of uranium 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, pricy Santa Fe. A young physicist, J. Robert Oppenhimer, directed the laboratory. The quiz bomb was cautiously put together on a desert devout 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 nerve tower on which the bomb was fixed had disappeared into superheated vapor. Three weeks later, on August 6, 1945 a get together States warplane blow up an atomic bomb over Hi roshima, Japan. This city of about 343,000 tribe co! unted 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 percentage of the buildings in Hiroshima were destruct or wrongfulnessd, and about 88 percent of those in Nagasaki. At a distance of one growl from the center of the explosion, 35 percent of the inhabitants were killed. Closer to the center-about one-half myocardial infarct away-85 percent died. Beyond a mile and a third, in that respect were very hardly a(prenominal) deaths. Some of theses people were killed by the plan of attack itself-by existence thrown down or by being hit with debris. The blazing flash of heat sear more than 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.         Buildings were completely destroyed or severely deadeningd 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 expiry ranged from pentad to eight square miles, with the most serious damage at heart the innermost two square miles. umteen test bombs halt been set off since 1945. Two were exploded at Bikini, an atoll in the paci fic, in 1946. Three were exploded in 1948 at Eniweto! k, a Pacific island employ as a changeless testing earthly concern by the U.S. Atomic skill Commission. Four more were set off at the alike(p) site in 1951. At Bikini, one bomb was exploded in the piddle of the lagune. The explosion lifted over a million tons of water high into the air. Battleships were anchored in the lagoon to determine the amount of damage that would occur. Various other tests break been made since that time, including atomic- machines 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 troops 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. twain 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 ha d 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 emergency to get a full essay, order it on our website: OrderCustomPaper.com
