The twentieth century made enormous technological, scientific and healthcare advances. Two of the greatest of these advances were landing a man on the moon and splitting the atom. Afraid the Nazis were going to manufacture an atom bomb, the United States government spent billions on the Manhattan Project. Adolph Hitler's Third Reich failed in their efforts. Finally, in 1945, the scientists of the Manhattan Project, led by J. Robert Oppenheimer, accomplished its goal. Upon seeing the detonation of the first atom bomb during the Trinity test in New Mexico, Oppenheimer quoted The Bhagavad Gita, "Now I am become death, the destroyer of worlds." Humanity now had a weapon that could not only completely destroy nations, but the whole planet.
