Albert Einstein came up with the proton theory and his special theory of relativity

1905

Hermann Minkowski discovered space time

1908

the nucleus was discovered

1911

Niels Bohr created specific-orbits model of atom

1913

Lois de Broglie discovered matter waves. Niels Bohr and H.A. Kramers discover probability waves

1924

Wolfgang Pauli put forward exclusion principle

1925

Werner Heisenberg discovered matrix mechanics

1925

Max Born contributed the probability interpretation of wave function

1926

Erwin Shrodinger thought up the wave equation that was later named for him and equated matrix mechanics with wave mechanics

1926

- Clinton Davisson and Lester Germer performed the Davisson-Germer experiment which demonstrated the wave nature of the electron.

1927

Neils Bohr contributed hugely with the idea of complementarity, that particle and wave function could be simultaneous

1927

J.S.Bell formed Bells theorem which states that no physical theory of local hidden variables can ever reproduce all of the predictions of quantum mechanics.

1964

Quarks were hypothesized

1964

David Bohm came up with the idea of implicate order.

1970

Henry Stapp studied nonlocal connections re: Bell's theorem

1971

Stuart Freedman and John Clauser performed the experiment which proved Bell's theorem based on the correlation of paired particles. It was later called the Freedman-Clauser experiment.

1972

Twelve new particles were discovered

1974 - 1977

Alain Aspect (born1947) performed the Aspect experiment verified the statistical predictions of quantum mechanics.
