It is August 6th, 2015. Seventy years ago an atomic bomb was dropped on Hiroshima, Japan. This bomb had the equivalent energy of about 20,000 tons of TNT. This HUGE amount of energy was generated by converting one GRAM of matter into energy. (One gram of matter is about the mass of ONE PAPER CLIP !!!)
