In the history of Americas, there have been a lot of interesting events. But like all of them or most, change America or break it, like the American Revolution, civil war. These event are just two of the many that America has. But the event that happened on August 9, 1945 is another accolade that can be added to America’s history. The bombing of Hiroshima and Nagasaki. This one event showed America’s power. Not only that the bomb that was used was never used again.

The bombs that were used were called the atomic bomb. Or what we now it knows as nuclear bomb. There are two types of atomic bombs fission and fusion. Fission in the dictionary means the splitting of an atomic nucleus resulting in the release of large amounts of energy. Fission bomb “simply put, is a nuclear reaction in which an atomic nucleus splits into fragments, usually two fragments of comparable mass, emitting 100 million to several hundred million volts of energy.” The second is fusion. Fusion in the dictionary is the union of atomic nuclei to form heavier nuclei resulting in the release of enormous quantities of energy when certain light elements unite. The fusion reaction is starts just like the fission but the difference is the fusion gets its power from fusing of nuclei and a lot of hydrogen isotopes.

Know that we know about the bombs and how they work. The person who started the theory is Albert Einstein. In 1905 Albert Einstein made an equation E=mc2. This equation means energy= mass times the speed of light squared. At first Einstein didn’t want to use the equation for bombs. But in 1939 a letter sent to president Roosevelt a rather convincing letter signed by Albert Einstein convincing him to build the bomb. Once that happened the United States started work on the atomic bomb.
Three years later thanks to the letter by Albert Einstein The Manhattan Project was created. This project was made to develop and build a atomic bomb. Also the Manhattan project was to compete with the...
