 * History of the Atom Timeline **


 * Date || Scientist || Accomplishment or breakthrough ||
 * 1803 || Dalton || In 1803, Dalton made a theory about different elements by differences in their weights. ||
 * 1901-1976 || Heisenberg || In 1927, Heisenberg stated that certain specific pairs of variables cannot be measured simultaneously with high accuracy. Most importantly he found out and showed that within an atom, it is possible to meaure the postion or momentum, of a particle such as a electron. It is not possible to measure them at the same time. ||
 * 1909 || Rutherford || Rutherford probed the structure of the atom. He found that the atom was too dense to break apart upon hitting a solid object. Instead of breaking apart, it would just bounce off of the item. ||
 * 1911 || Thomson || He ventured to find the interiors of the atom. He found that there were consuples in the atom. ||
 * 1915 || Bohr || The Bohr model was proposed by Niels Bohr ||
 * 1932 || Chadwick || Discovered The Neutron ||
