The Atomic Bombing of Hiroshima and Nagasaki

World War II began on September 1st, 1939 when the Germans invaded Poland and then ended on September 2nd, 1945 with the signing of the surrender documents from Japan aboard the American Battleship USS Missouri. During the course of 1941 when the US joined WWII, and 1945 when it ended over 291,000 US American Soldiers died. To shorten the span of the war and to save the lives of countless American soldiers the United States would have to produce the greatest possible blow upon the Japanese. The Atomic Bomb provided such a blow.          The idea of creating an atomic bomb first came from a letter to President Franklin Roosevelt from Albert Einstein in 1939. The letter had stated the Germans were trying to enrich uranium-235 in which the process would allow them to build an atomic bomb. This letter from Albert Einstein prompted President Roosevelt to create the Manhattan Project, in which the US will enrich and create an atomic bomb using uranium-235 before the Germans. The Manhattan Project had span over the course of six years, from 1939-1945 and more than $2 billion dollars were spent over that time period.         To make an atomic bomb is very hard even for the physicists and engineers who put it together, but they pulled it off with the help of the most brilliant minds of the time. Uranium-235 was the main element used to create the atomic bomb “Little Boy.” To extract the Uranium-235 from pure Uranium is very difficult because Uranium-235 is 0.7% concentrated in the ore. To be useful in a nuclear weapon the concentration needed to be increased, this process is called enrichment. The rest of the Uranium ore however is Uranium-238 which is useless for Atomic Fission (splitting the atom for an explosive reaction) and nuclear warfare. The process of enriching the Uranium is...
