Roosevelt in 1939, the year WWII began, that there was plenty of evidence in Germany to suggest that an extremely powerful and devastating atomic bomb could be created. The power in an atomic bomb comes from the nuclear fission of uranium, breaking the atoms for a release of energy, amidst the explosion. At 8:15 in the morning on August 6, 1945, Little Boy was dropped from Enola Gay onto Hiroshima. The mechanism of the bomb was designed so that it detonated about 600 meters above the city. The target was a bridge that crossed the Ota River and was in a “T” shape, Aioi Bridge. Within a tenth of a second of exploding, the huge fireball was already 30 meters in diameter. At one second the explosion was at its maximum size of 370 meters in diameter and had an initial temperature of over 10,000,000 ºC (18,000,000
