The 100 foot tower which housed the bomb was totally destroyed by the blast. ("World War II", 1997, 1-2). After the bomb exploded, Robert Oppenheimer, the head of the Manhattan Project, said, "Behold. I have become death, destroyer of worlds." (Hoare, 1987, 18) When Harry Trum... ... middle of paper ... ...p; The United States, as well as the Allied forces, saved many lives by dropping the atomic bomb.
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 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 The Manhattan Project was the code name of the America’s attempt to construct an atomic bomb during World War II. It was named after the Manhattan Engineer District of the U.S. Army Corps of Engineers, because a lot of it’s earlier research was done in New York City. An atomic bomb is a weapon that uses the energy from a nuclear reaction called Fission for its destruction. The idea that mass could be changed into energy was predicted by Albert Einstein in the earlier part of the 1900’s. John D. Cockcroft and Ernest Walton confirmed this by experiments in 1932.
However, on August 29, 1949, the Soviet Union shocked the entire world with their first nuclear bomb named “First Lightning”. The world did not think that the Soviet Union was this far along in their nuclear weapons. The United States felt threatened. The nuclear arms race had began. The Hydrogen bomb The hydrogen bomb, a stronger version of nuclear bomb, which uses a fission bomb to ignite thermonuclear fuel, marked a new and extremely important stage in the nuclear arms race.
In 1939 rumor came to the U.S. that Germans had split the atom. The threat of the Nazis developing a nuclear weapon prompted President Roosevelt to establish The Manhattan Project. Oppenheimer set up a research lab in Los Alamos, New Mexico and brought the best minds in physics to work on the problem of creating a nuclear weapon. Although most the research and development was done in Los Alamos, there were over 30 other research locations throughout the project. After watching the first nuclear bomb test Oppenheimer was quoted as saying simply “It works.”.
Atomic Bomb On August 2, 1939 Albert Einstein wrote to President Franklin D. Roosevelt. This was right before the start of World War 2. In this letter Einstein and several other scientists told Roosevelt of the efforts Hitler was making to purify U-235 in which he hoped to make an atomic bomb. This is when the United States started the Manhattan Project. This was the project of making an atomic bomb.
Two days after the first bomb was dropped the U.S.S.R declared war on Japan. On August 9, we dropped the bomb on Nagasaki at about 10:58 AM. The results were slightly greater than the Hiroshima bomb. This bomb caused these cities to turn into complete rubble, there was nothing left standing with in a four square mile radius of where the bomb hit. So on September 2, 1945; General MacArthur accepts Japans formal surrender aboard battleship Missouri in Tokyo Bay.
The need for a nuclear bomb became present in 1941 after the attack on Pearl Harbor when the United States entered World War 2. Albert Einstein and Enrico Fermi who were the fathers of the Manhattan Project. Einstein and Fermi were worried about what would happen if the Axis powers got their hands on an atomic bomb (US History.com). An atom bomb works by firing stray neutrons at closely pact uranium atoms. 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).
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).
