|History of XX Century Physics|
of physics by areas; history of quantum physics, of relativistic
physics and of relativistic cosmology.
* Initial situation: Physicists thought essentially everything was understood, with their theories of matter and energy, electricity and magnetism, heat, sound, and light; A few small outstanding problems would be fixed soon, like the failure to detect ether, the nature of X-rays, radioactivity, and the black body.
* Overview: Radical changes occurred in the structure of physical theories, due to special relativity and quantum mechanics in the first 30 years, then due to our increased understanding of dynamical systems and complexity from the 1970s, and of the subatomic world; Germany and then the US play prominent role in research.
* 1911: Rutherford postulated the existence of the atomic nucleus, which led him to his atom model; Max Planck introduced the quantum concept of zero-point motion; and Heike Kamerlingh Onnes announced the discovery of superconductivity in mercury below a critical transition temperature.
* 1920s: Neither relativity theory nor quantum theory were viewed by all as the future of physics (see J Larmor).
* 1930, particle physics: Matter is made of e, p, γ, interacting by electromagnetic and gravitational forces.
* 1930s: Jordan introduced annihilation and creation operators (who first realized that everything is made of field quanta), viewed with suspicion by Pauli.
* 1947: Bethe published a short calculation of the Lamb shift in agreement with experiment, and convinced the experts that QED was physically correct.
* 1962, particle physics: Headline makers are Chew, Mandelstam; Hot topics are bootstraps, N/D methods, strip approximations.
* 1964: Gell-Mann and Zweig proposed the quark model for hadrons.
* 1969: High-energy collisions between electrons and protons produced the first indications of quarks inside the protons.
* 1999, news: Speed of light in a medium reduced to 17 m/s.
* 2000, news: Discovery of ντ; Discovery of the quark-gluon plasma and some evidence for the Higgs boson.
