In Newtons theory of classical mechanics system set up for our shadowat, omic nucleus physics and after how many scientists of derivation and validation is born again and again! The long river of years may obscure past dust, but it cannot block the shine like gold of course! In this article, we will through the literature research and survey method and steps of scientists, to the cognitive development of nuclear physics. And emphatically based on the research of the rutherford to alpha rays, especially of alpha particles, large Angle scattering experiment, after found to experience personally the nucleus. Finally discussed the discovery and development of atoms and physical brings to the human, the advantages and disadvantages of the correct treatment of science, applied science, make our home more beautiful.
