THE UNIVERSAL NUCLEAR THREAT OF THE ATOMIC BOMB

During World War II, the United States, with the assistance (collaboration) of physicists, mathematicians, and engineers from the U.S., Britain, Canada and Europe, completed the Manhattan Project to produce the first atomic bomb.
(The project started as the "Manhattan District Engineers" and only became "The Manhattan Project" some time later).

Germany was also working to develop atomic weapons, but was hampered by many technical and political problems (including sabotage and Allied bombings) which prevented their successfully completing their work. This left the U.S. as the only nation to ever unleash nuclear weapons in an attack.

In 1939, at the urging of Dr. Leo Szilard, Einstein wrote to President Roosevelt warning of a new discovery of a "nuclear chain reaction in a large mass of uranium." Einstein forewarned President Roosevelt that the discovery of such a reaction could lead to the construction of "extremely powerful bombs of a new type." Einstein also mentioned that Dr. Leo Szilard was working on this and urged the US to find this reaction before Germany. It was Einstein's letter that led President Roosevelt to funding uranium research and later to the Manhattan Project.

The physicist Albert Einstein did not participate directly in the invention of the atomic bomb-but was instrumental in facilitating its development. His Special Theory of Relativity emphasized that a large amount of energy could be released from a small amount of matter. This was expressed by the equation E=mc2 (energy = mass times the speed of light squared). The atomic bomb would clearly illustrate this principle.

The first demonstration of "the gadget" (the code name for the first atomic bomb) was at Trinity site in Alamogordo, New Mexico, and it proved that the weapon would detonate and that the chain would build as predicted. The second and third demonstrations were conducted in Japan, which brought a quick end to the Second World War. Just up to and during World War 2
