The Manhattan Project

Definition

The Manhattan Project is when the United States started and finished the development of the atomic bomb, and ultimately we used it to try and end the war that we where in.

Detail Cause:

How the project came about is when then united Sates was in World War ll. We where fighting against the Axis, and received information from Albert Einstein that the germans where building some type of mass destruction weapon. So it was a race to see who could develop first, and the Americans had won the race.

Detail Characteristics:

In June 1944, the Manhattan Project employed some 129,000 workers, of whom 84,500 were construction workers, 40,500 were plant operators and 1,800 were military personnel. As construction activity fell off, the workforce declined to 100,000 a year later, but the number of military personnel increased to 5,600. Some famous scientists that advised over the project where Dr. James B. Conant, Richard Tolman, and Robert Bacher. In todays money the $20 billion project resulted in the production of the first uranium and plutonium bombs. On August 6, 1945, an American B-29 "Flying Fortress," the Enola Gay, dropped the uranium bomb over Hiroshima. Sixty thousand people were killed instantly, and another 200,000 subsequently died as a result of burn and radiation injuries. Three days later, a plutonium bomb was dropped over Nagasaki. Although it missed its actual target by over a mile, the more powerful plutonium bomb killed or injured more than 65,000 people and destroyed half of the city. In Nagasaki, a smaller area of the city was actually destroyed than in Hiroshima, because the hills which enclosed the target area restricted the spread of the great blast; but careful examination of the effects of the explosion gave evidence of even greater blast effects than in Hiroshima. The bomb that went off above Hiroshima, was set off at 600 meters above the ground. The Nagasaki bomb was detonated at 500 meters.

Detail Characteristics:

The lasting effects of the Manhattan Project are undoubtedly greatly significant. The project had both positive and negative effects. The significance of the Manhattan Project was that it put an end to WWII by using weapons of mass destruction and forced Japan to surrender.The legacy is without doubt great, it produced great advances in physics, engineering and is the origins for many areas such as nuclear energy and nuclear medicine. As well as this, a national network of laboratories remain: The Lawrence Berkeley Laboratory, Los Alamos National Laboratory as well as many others. The justification for whether it was morally correct and necessary to drop the nuclear bombs on the two civilian populations has constantly caused debate even to the current day. Regardless, the project itself is an amazing story of scientific and military development with impacts lasting to the current day. The dropping of the bomb forever changed the meaning of war for all citizens of the world.
