History Of The First Atomic Bomb Essay

Then he went to teach at Berkley University.4 Another main person in the research project was Enrico Fermi. Fermi was a graduate of the University of Pisa, where he received his Ph.D. Fermi then went to the University of Rome teaching chemistry and biology. Fermi played a major role in the development of the bomb by creating a sustained nuclear fission chain reaction, which was critical to making the atomic bomb.4 Richard Feyman was another scientist which worked on the atomic bomb. Feyman graduated from Princeton where he excelled in physics and other scientific studies. Feyman's big duty on the Manhattan Project was to break big problems into smaller easier to do problems.4 The Manhattan Project, also had to have facilities for the research and testing of the atomic bomb. Some of the facilities built by U.S. Army Corps of Engineers included: power stations, factories, steel works, hospitals, laboratories, and housing for everybody that worked on the project.. Other facilities that were built for the construction of the bomb were plants to make the radioactive material needed to construct the bomb. Oak Ridge, Tennessee was used to make uranium which was used as an explosive to react with plutonium. The plutonium itself was made in Hanford, Washington.5 To make this explosion possible, a piece of uranium was fired at another piece of uranium to make the critical mass that was needed for an explosion. Critical mass is the exact amount of

The dropping of the Atomic Bomb changed not only warfare forever, but also all international relations. With that being said, the decision to do so was one of the biggest decisions made by any government in the history of time. Nuclear warfare was way more destructive and way faster than any other form of warfare preceding. With the United States seemingly always viewed to be “the good guys” it is puzzling that this country is the same one who killed hundreds of thousands of people all at once and essentially ruined not one but two entire cities within minutes of dropping two single bombs. This decision was not taken lightly, and with basically two schools of thought, liberalism vs. realism, insisting to do so or not to do so, and realism won out. Realism and the many counterparts that strengthen this school of thought is what drove the decision to go ahead and drop the atomic bomb.

Bombing two major cities may seem wrong but it was necessary in order to come out as a successful nation. During World War 2 on August 6th and 9th of 1945 the United States was the first country to use an atomic device against an enemy. This enemy was the country of Japan. After the Japanese killed thousands of U.S soldiers with their ruthless and unexpected attack on Pearl Harbour the United States released two atomic bombs on their two major cities. These cities were known as Nagasaki and Hiroshima. After the bombs were dropped the war was put to an end. The use of the atomic bombs is a widely debated topic on whether their use was necessary or not. The bombings of Hiroshima and Nagasaki were not only necessary to end the war but it was also necessary because many American lives were lost.

In 1945, the Japanese attacked Pearl Harbor without a warning and killed about 2,400 Americans. Later in 1945, the Americans attacked Hiroshima without a warning. The Americans also bombed Nagasaki, but the Japanese were warned and were given three days to evacuate or surrender. The United States’ decision to drop the atomic bombs on Hiroshima and Nagasaki was a military measure to destroy the Japanese military, force Japan’s surrender, and save American lives.

The Manhattan Project was a research and development project that produced the first nuclear weapons during World War II. The Manhattan project was the invention of the first two nuclear bombs, Fat man and little boy. These two bombs were dropped on Japanese islands to end World War II.

In the 20th century- 1945 to be exact- during World War 2 a burst of light followed by an immense explosion with more power than 20,000 tons of TNT headed for Hiroshima, Japan. This was the world’s first atomic bomb, and 3 days later another one was dropped but this time on the city of Nagasaki. The U.S. dropped these bombs in order to trap Japan in a corner and leave them no choice but to surrender. This controversial event has led many to wonder if it was in fact a military necessity and yes it was, not only did it stop the war, it saved the lives of many American and Japanese soldiers, and it stopped Japan from breaking the international laws of warfare.

Secretary of War, Stimson was able to raise the possible outcomes that will come from the use of the bomb on non-combatants. It would taint the United States ‘international standing and reputation” . However, Truman did not take the location of the city into consideration. Furthermore, he was not particularly concern with the targets because he believed the air force would take of that. He left that to the military officials that were in charge of the operation, but he wanted to women or children to get hurt in the process. Ultimately, Truman trusted his officials in the matters of the atomic bomb. He’s faith in his official determined the consequences that would erupt.

On the morning of August 6, 1945, a B-29 Bomber that was names Enola Gay had flew over the City of Hiroshima Japan and dropped the first atomic bomb to have ever been made. The motive for the creation and research of the bomb was a direct result of the Japanese bombing on Pearl Harbor. When the bomb was finalized after all the research of splitting atoms and combining plutonium and uranium and knowing what to use, many tests were done and the bomb was presumed ready. But no one could have guessed the magnitude of this bomb. The city was engulfed in flames as the power of the bomb being equivalent to 20,000 tons of TNT being dropped exploded. There was much work that went into making this project a success amongst all others. There was a wide variety of scientific brain knowledge, civilian knowledge and much military knowledge and assembly to make this project happen.

The Atomic Bomb was the deadliest weapons in the history of war. Throughout World War II one of the most stubborn countries to surrender was Japan who relentlessly fought against the United States of America. After failing to defeat America, Japan was overwhelmed by allied forces. Staying with tradition however, Japan would rather die in battle than to surrender. The Soviet Union also fought against America but that was towards the end of the war. The United States dropped both of the Atomic Bombs in order to intimidate the Soviet Union and to make Japan to surrender unconditionally.

Christian Meza SLIDE 1: Specifics of the historical topic or issue WHO was involved?Both America and Japan and been involved in this event. It started when Japan attacked Pearl Harbor with no warning. WHAT happened?An atomic was dropped on the city of hiroshima to end the war between America and Japan quickly. The Japanese had been using extreme tactics and the U.S finally realized it was time to end it.

During World War II, the U.S., Germany, and Japan we’re all at war. Germany expanding, Hitler rising in power, Japan fighting, and the U.S. At the start of the war, the bomb was not yet invented. People realized that one of the only ways to defeat the others in war was by large explosions, but nobody had that kind of technology yet. There was a task set for scientists. With the approval of president Franklin D. Roosevelt, they began the Manhattan project. This was the creation of the Atomic Bomb.

World War Two and the Atomic Bomb World War II is one of the most historic points in the history of the world. The war was by far the most devastating in the history of the world. There were many controversial actions during the war, but one of the biggest was the decision by the United States to drop atomic bombs. The atomic bomb should have been used to end the war because it saved more lives than continuing the war. The official bombing order was signed on July 25, 1945, by Thos.

In early 1900’s scientist of the world discovered that a few German physicists had learned the secret of splitting atoms, and they would be able to utilize energy to produce a bomb that would cause total destruction. Albert Einstein, who fled Nazi Germany and fled to United States, informed President Roosevelt about the capability of splitting atoms. Along with Einstein fellow scientist Fermi convinced Roosevelt to develop an atomic research program. In 1941 United Stated begin to design and build the atomic bomb which coded the Manhattan project. In 1942 Fermi had produced nuclear chain reaction. The development of the atomic bomb took place in Los Alamos, New Mexico. Oppenheimer was the leading scientist in putting all the pieces together. There were over a hundred thousand people involved in preparing the bomb to be tested. December of 1945 the testing for the first atomic bomb took place in New Mexico.

The research of the bomb took place in over 30 locations across the United States and Canada, and the development of the bomb took place in Los Alamos, Mexico (Siracusa 34). Through extensive research by many world-renowned physicists, it was concluded that uranium-235 was the best choice for the atomic bomb and was chosen as the energy source of the first bombs. Once tested, the bombs were built and used as the final assaults in World War II against Japan.

Some regard the atomic bomb as “the thank God for the atom bomb”. This places God on the U.S. side and regards the bombs as our saving grace. This bomb forced the Japanese to surrender which in turn proved the U.S. to be the heroes who saved the American’s lives.1 The Americans intended on ending the war but did not expect to end it with such a large number of casualties. The results of the atomic bomb and how it effected the Japanese people both emotionally and physically will be addressed. “The bombs marked both an end and a beginning—the end of an appalling global conflagration in which more than 50 million people were killed and the beginning of the nuclear arms race and a new world in which
