It provided the quick but still violent end to WWII with the surrender of Japan. What was first believed to be just a "bigger" bomb caused over 200000 deaths in Nagaski and Hiroshima in Japan. The rise of nuclear technology helped end WWII but gave way to the Cold war with the Soviet Union. This war brought fear to both the U.S. and the Soviet Union citizens.
Also present in science and nuclear technology are nuclear power plants. Just 38 years after the drop of the first atomic bomb on Japan, such devestating power is used in a more useful and beneficial way: producing a source of energy. Nuclear power plants provide a more cleaner
