EXPLANATIONS BELOW
Concept note-1: -It looked increasingly likely that the United States would have to commit itself to a land invasion, which could have claimed many American lives. Instead, the atomic bomb served as a tool to bring the war in the Pacific to a close sooner.
Concept note-2: -The first atomic bomb, named Little Boy, was dropped on Hiroshima from the Enola Gay, a B-29 bomber, at 8:15 AM on August 6, 1945. The second bomb, named Fat Man, was dropped on Nagasaki from the Bockscar, also a B-29 bomber, at 11:02 AM on August 9, 1945.
Concept note-3: -The two atomic bombs dropped on Japan in 1945 killed and maimed hundreds of thousands of people, and their effects are still being felt today. By the end of 1945, the bombing had killed an estimated 140, 000 people in Hiroshima, and a further 74, 000 in Nagasaki.
Concept note-4: -On 6 August 1945, at 08:15, the first bomb was dropped on the centre of Hiroshima. ‘Little Boy’ was a gun-type fission bomb, using a conventional explosive charge to fire one sub-critical mass of uranium into another. This kind of device had never been tested before, but the scientists were confident it would work.
