Although this explosion was spectacular, the deadly force of an atomic bomb was shown when the United States dropped an atomic bomb on Hiroshima during War II. The bomb destroyed the city. Then again on August 9th, a bomb dropped on Nagasaki. The devastation was widespread and quick. The economy was utterly a disaster.
At this site, scientist and laborers were separating U-235 from U-238. Here the Hiroshima bomb was built in huge buildings and the locals could only imagine... ... middle of paper ... ...s. 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 Atomic Bomb The research for the first Atomic bomb took place in the United States, by a group of nuclear engineers; the name of this research was called, “The Manhattan Project”. On July 16, 1945, the detonation of the first atomic bomb was tested near Los Alamos, New Mexico. As the atomic bomb was detonated, it sent shock-waves across the globe, which demonstrated that nuclear power would forever change the meaning of war. To create a nuclear bomb, nuclear fission must occur. The process of nuclear fission was splitting the nucleus of an atom.
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.
They were given the code name Project Y. One bomb, using plutonium, was successfully tested on July 16, 1945, at a site 193 km south of Albuquerque, N.M. The first atomic bomb to be used in warfare used uranium. It was dropped by the United States on Hiroshima, Japan, on Aug. 6, 1945. 3 days later, Nagasaki got bombed badly.
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).
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”.
Showing to be the fastest slaughter that we have ever observed, the bomb in Hiroshima killed about 280,000 civilians and 40,000 members of the military. For those not killed by the immidiate consequences of the bomb, radiation destroyed cells within the human body and still claims the lives of people today. It was estimated that by December 1945, around 140,000 people died from radiation related illnesses. One factor that created much immediate damage was the spread of the blast and its shock waves. In only ten seconds after the landing of the bomb i... ... middle of paper ... ...about.
For this reason, he established a national defense research Committee to further develop Einstein’s researches with the aim of building the atomic bomb before the Germans do”(manythings). To close a dramatic chapter of brutal fighting during World War II, the United States used the atomic bomb in august 6, 1945 bombarding Hiroshima, Japan. The second bombing was “three days later when the United States dropped another atomic bomb over the city of Nagasaki, Japan”(Teachinghistory).

Atomic bombs were the first nuclear weapons to be developed, tested, and used. In the late 1930s physicists in Europe and the United States realized that the fission of uranium could be used to create an extremely powerful explosive weapon. In August 1939, German American physicist Albert Einstein sent a letter to U.S. president Franklin D. Roosevelt that described this discovery and warned of its potential development by other nations. The U.S. government established the top secret Manhattan Project in 1942 to develop an atomic device. The leader of the Manhattan Project was U.S. Army Brigadier General Leslie R. Groves.
