• Wolfgang Pauli Neutrons

    In a famous letter written by him, Pauli said that, in addition to electrons and protons, atoms also contained an extremely light neutral particle which he called the "neutron".
  • Enrico Fermi Nuclear Chain Reaction

    He Invented The First Nuclear Chain Reaction
  • Clemens C. J. Roothaan and George G. Hall

    Derived the Roothaan-Hall equations, putting rigorous molecular orbital methods on a firm basis.
  • Clauss Jönsson

    Performed Young's double-slit experiment for the first time with particles other than photons by using electrons and with similar results, confirming that massive particles also behaved according to the wave–particle. that is a fundamental principle of quantum field theory.
  • Pier Giorgio Merli

    Performed Young's double-slit experiment using a single electron with similar results, confirming the existence of quantum fields for massive particles.
