... 1930s physicists in Europe and the United States realized that the fission of uranium could be used to create an extremely powerful explosive weapon. In August 1939, German American physicist Albert Einstein sent a letter to U.S. president Franklin D. Roosevelt that described this discovery and warned of its potential development by other nations (Tibbets). The U.S. government established the top secret Manhattan ... left over.

... been around for 100 years. Discovered by Antoine Henri Becquerel in 1896, it was quickly studied by the scientific community. Albert Einstein formulated his "Theory of Relativity" in 1905, stating if mass could be transformed into energy, the energy liberated would be massive. Einstein's theory would be proved thirty-three years later by Otto Hahn, along with his partner Fritz Strassman ("World Mysteries ... we only recently began to understand the enormous power contained in these tiny molecules.

... Americans soon became part of the race to build the bomb. Leo Sziland, a brilliant Hungarian went to warn Einstein about the atomic progress in Germany (Knebel and Bailey 504). Albert Einstein was in Long Island at his summer home when Sziland informed Einstein of the Germans progress. Einstein sent President Franklin D. Roosevelt a letter to warn him about the news he had heard. The letter arrived ... ...

... City. An atomic bomb is a weapon that uses the energy from a nuclear reaction called Fission for its destruction. The idea that mass could be changed into energy was predicted by Albert Einstein in the earlier part of the 1900's. John D. Cockcroft and Ernest Walton confirmed this by experiments in 1932. Then in 1938, nuclear fission was discovered by German scientists, and it ... was feared by many of the U.S. scientists, that Hitler would try to build a fission bomb.
