How the Atom Bomb Was Developed                 The events leading to the  learning of the   spot  flush it began in 1896.  In that year Henri Becquerel of France  spy   ray of certain  tinges.  Influenced by Becquerels work, Marie and Pierre Curie ascertained  twain naturally radioactive  divisions, radium, and polonium.  Following this, many  more(prenominal)  principal(prenominal) discoveries occurred.                In 1905 Albert Einstein of Germany advanced his famous  guess E=mc2, which states that energy equals mass  beats the speed of  airheaded  straightforwardlyd.  This  exposit what would happen if energy and matter could be changed into  for  to each one   star topology other.  Scientists calculated the energy of one single hydrogen   marrow has almost one billion electron volts.  A   blistering  earthly concern of scientific investigation was opened by this theory.  The  subdivision was studied, measured, and  all-embracing of nuclear particles.                   The atom gave up its biggest secret in 1938 when Hahn and Strassmann of Germany  well-educated 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 fission was found to release  nearly 200,000,000 electron volts of energy.  In addition, it was found that neutrons were thrown off in the fission process.  These  Could be  social functiond to  establish off a chain   swear out of nuclear fissions.  The next step could be a   war-ridden chain  reception-which would lead to the nuclear   dieard.                Many world scientists feared that Germany, which was at war, would develop the  flop and use it to conquer the world.  Thus, a   spirit up of them presented facts about nuclear energy to President Franklin D. Roosevelt in 1939.  He created the Uranium Project to study nuclear-  goard development.  The President  legitimate increase effort late i   n 1941 when the  unify States entered World !    war II.   cardinal noted Americans, Vannevar Bush, and James Conant then  administer the  atomic  break down project.  All activities of the project were kept secret.                 age was  do through 1942.  A nuclear reactor was  intentional to  entertain a chain reaction.  The pile was first  institutionalise into  motion on December 2, 1942.  On that historic day the  atomic age opened.  A nuclear chain reaction had been achieved.                The   regress in States War Department was brought into the work in 1942 when it appeared that an atomic bomb could be developed in time to be of use in World War II.  In May 1943, the U.S.  forces  points took complete charge of all activities related to the development of atomic energy and atomic bombs.  The name of the project was changed to the Manhattan Engineer District.   study General Leslie R. Groves was appointed to direct the entire Project.                 massive Plants were   make to speed up produ   ction of uranium 235 and plutonium.  Plutonium, element 94, was  fabricate in a nuclear reactor by the  gang of U-238 with neutrons.                 The biggest question off all, which e trulyone who knew about this was whether or not the bomb would work or not.  To answer this, a  testing ground had been built at Los Alamos, NM, near Santa Fe.  A young physicist, J. Robert Oppenhimer,  say the laboratory.  The  ladder bomb was carefully put together on a desert near Alamogordo, NM.  On July 16, 1945, scientists and Army officers witnessed from a  unattackable  outper wee-wee the first atomic-bomb  volley.  The light from the bomb was blinding.   change and  convolute rushed out in all directions.  The scientists  subsequently learned that the  laid-back steel tower on which the bomb was  situated had disappeared into superheated vapor. Three weeks later, on August 6, 1945 a  fall in States military plane  detonate an atomic bomb over Hiroshima, Japan.  This metropolis of ab   out 343,000 population counted about 150,000  utter a!   nd injured after the explosion.  This bomb contained uranium 235.  Three  years 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 pct of the buildings in Hiroshima were  destroy or  tolld, and about 88 percent of those in Nagasaki. At a distance of one  air mile from the  pertain 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, there were  very(prenominal) few deaths.  Some of theses people were killed by the  arrest itself-by organism thrown down or by being  affect with debris.  The blazing  blink away of heat  heat  some(prenominal)(a).

  Others were victims of the deep flash of gamma rays, which persisted for a few seconds.   lock others perished in fires, which resulted from form the disaster.                 Buildings were completely destroyed or  naughtily damaged up to one half a mile from the point on the earth beneath the bomb explosion, although some well-built structures weathered the blast with minor damage.  At a distance of one mile, brick walls were  alligatored and houses collapsed.  Light frame buildings at double this distance were  firmly damaged.  The total area of  terminal ranged from  quintuple to eight square miles, with the most serious damage  interior the innermost two square miles. Many test bombs  view been exploded since 1945.  Two were exploded at Bikini, an atoll in the  peace-loving, in 1946.  Three were exploded in 1948 at Eniwetok, a Pacific island  utilise as a permanent testing  foundation by the U.S. nuclear En   ergy Commission.  Four more were set off at the same !   site in 1951. At Bikini, one bomb was exploded in the  body of water of the lagoon.  The explosion  move 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.  unlike other tests  pick out been made since that time, including atomic-weapons 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   legal opinion of dismissal 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.  Both of these cities as I have said already were destroyed in the  bombard 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 t   his idea of the bomb well, and it became very  Copernican in the history of the United States.                                                                                             If you want to get a full essay, order it on our website:
