Choose a scientist and explore his or her discoveries. Be able to explain how those discoveries have had an impact on our world today. In class, you will speak as if you are that person to create a living timeline about the history of atomic advancements.
Nagaoka: Postulated a "Saturnian" model of the atom with flat rings of electrons revolving around a positively charged particle.
Albert Einstein: Published the famous equation E=Mc2

Hans Geiger: Developed an electrical device to "ping" when hit with alpha particles. Known as a Geiger counter.
R.A. Millikan: Determined the charge and the mass of an electron.
E. Rutherford: He established that the nucleus was very dense, very small and positively charged.
H.G.J. Moseley: Using x-ray tubes, determined the charges on the nuclei of most atoms.
Niehls Bohr: Developed an explanation of atomic structure that underlies regularities of the periodic table of elements
De Broglie: Discovered that electrons had a dual nature-similar to both particles and waves
Heisenberg: Described atoms by means of formula connected to the frequencies of spectral lines
Schrodinger: Viewed electrons as continuous clouds and introduced "wave mechanics" as a mathematical model of the atom
Paul Dirac: Proposed "anti-particles"
James Chadwick: Discovered the neutron
Enrico Fermi: Called the "architect of the nuclear age" and the "architect of the atomic bomb"
