The discovery of nuclear fission made by Otto Hahn, Lise Meitner and Fritz Strassman, allowed the first atomic bomb to be built.
It was first built in a laboratory in Berlin, Germany. Nazi Germany never got around to using it, however. -
Einstein, working as a professor of Physics at the University of Berlin, found out about the discover of nuclear fission, and sent a letter to the President of the United States, warning him of the dangers.

This date marks the 50th anniversary of the bombings. Japan is thrust on the world stage as it remembers what happened there half a century ago.
-
Scientists and physicists are still developing technology for weapons and bombs, but hopefully it will not be needed.
