In the 1930's scientists were finding very intriguing things about the use of the atom's power and atomic fission. Fission is the process by which the nucleus of a heavy element absorbs a neutron, which forces it to split into two nearly equal halves. Scientists discovered that when an atom split, the sum of all the parts it split into did not, in fact, add up to the original mass (weight) of the atom. In fact, well over 99.9% of the mass was accounted for, but some small amount appeared to have vanished. According to Einstein, matter and energy are related. …
