Why did Robert Oppenheimer make the atomic bomb?

Following the 1939 invasion of Poland by Nazi Germany, Oppenheimer was selected to administer a laboratory to carry out the Manhattan Project, a U.S. Army experiment aimed at harnessing atomic energy for military purposes. He led the scientific end of the Manhattan Project in Los Alamos, New Mexico, beginning in 1942.Click to see full answer. Keeping this in view, what did Robert Oppenheimer say about the atomic bomb?As he witnessed the first detonation of a nuclear weapon on July 16, 1945, a piece of Hindu scripture ran through the mind of Robert Oppenheimer: “Now I am become Death, the destroyer of worlds”. It is, perhaps, the most well-known line from the Bhagavad-Gita, but also the most misunderstood.One may also ask, why did Oppenheimer quote Bhagavad Gita? I remembered the line from the Hindu scripture, the Bhagavad-Gita; Vishnu is trying to persuade the Prince that he should do his duty and, to impress him, takes on his multi-armed form and says, “Now I am become Death, the destroyer of worlds.” I suppose we all thought that, one way or another. Likewise, people ask, why did the US decide to use the atomic bomb? President Harry S. Truman, warned by some of his advisers that any attempt to invade Japan would result in horrific American casualties, ordered that the new weapon be used to bring the war to a speedy end. On August 6, 1945, the American bomber Enola Gay dropped a five-ton bomb over the Japanese city of Hiroshima.How did they create the atomic bomb?This is known as a chain reaction and is what causes an atomic explosion. When a uranium-235 atom absorbs a neutron and fissions into two new atoms, it releases three new neutrons and some binding energy. Two neutrons do not continue the reaction because they are lost or absorbed by a uranium-238 atom.
