E=mc 2 so simple and yet. . . Lise Meitner, in cooperation with other scientists discovered this amazing power. A physicist, Lise Meitner was experimenting with uranium. She attempted to make it bigger my bombarding the nucleus with neutrons. Unknowingly, Meitner fissioned the nuclei. She and her partner, Otto Hahn (a chemist), noticed that mass seemed to be missing.

She was forced to leave Germany as the Nazis gained power. She continued correspondence with Hahn, and also continued her research. Meitner and her nephew, Otto Robert Frisch, discovered that uranium nuclei fission when bombareded by neutrons. She also calculated the energy release of the observed fission; the numbers concurred with Einstein's E=mc 2.

The Manhattan Project. Leo Szilard and Albert Einstein presented the issue to President F.D. Roosevelt. A commitee was organized and assigned to uranium research. Upon hearing the success of the Nazis in Europe, the U.S. reconsidered research in the nuclear field. Research needed to advance more quickly if a bomb was going to be used in the war. A month after the Japanese bombed Pearl Harbor, FDR gave "his tentative approval to proceed with the construction of an atomic bomb (The Atomic Bomb An Interactive History)."

The Manhattan project culminated to the detonation of atomic bombs on Japan.media type="youtube" key="40E1HH3JYz0" height="385" width="480"
