• p11 1909-11 Rutherford and Marsden bombard gold foil with alphas, 1/10000 bounce back, demonstrates dense positive nucleus less than 1e-12 by volume.
• p12 1913 Bohr "planetary" model for electron, except solar system planets denser than electrons in atoms
• p13 quarks smaller than 1e-4 nuclear radius

• p15 Patrick Blackett 1921-4 23,000 cloud chamber photographs of alphas bombarding nitrogen, eight examples of proton ejection and an oxygen

• p19 Chadwick neutron 1932

• p23 Pauli hypothesized neutrino 1931

  • proton, neutron, electron, neutrino spin 1/2

• p25Joliot-Curies irradiated aluminum with alpha (helium) particles from radium (or polonium?), produced phosphorus-30 with 3 minute half life

• p26 Al[13p14n] + He[2p2n] => n + P[15p15n] ( 3 min ) => Si[16p14n] + positron + neutrino

• p26 1935 Nobel, Frédéric suggests "transmutations of an explosive type"

• p27 Hahn and Strassmann fission 1938, Fermi slow neutrons with paraffin or water so they don't shatter nuclei

• 027 Lisa Meitner and Otto Frisch liquid drop model, instability, fission

• 028 Planck law E=hv

• 032 Strong force, neutron stability in nucleus

• 03 pions emitted when neutrons or protons "pummeled"
