Otto Hahn was a German chemist who discovered fission, fission is the action of dividing or splitting something into two or more parts. When Hahn discovered nuclear fission he unintentionally discovered how to create an atomic bomb. Hahn discovered nuclear fission by having a speed neutron hit a uranium atom, the uranium atom spit. When the speeding neutron hit the nucleus of the uranium atom the atom stretched until it split. Before this, Niels Bohr had a theory that a nucleus must be “like a wobbly droplet of liquid.” Hahn discovered that this theory was indeed accurate. When Hahn split the atom there was enough energy to make a grain of sand jump, but he was curious to see if he used a larger piece of uranium what would happen, if
