... The first theory that justified this was done by Wilson and Sommerfeld: they conjectured that electron orbits can be elliptical, of which a circular orbit is a special case. Each orbit is specified by 2 parameters instead of 1. Geometrically by semi-major and semi-minor axes a,b, no just radius r. T ...

... If an electron behaves as a wave, how do you specify a position of a wave at a particular moment? Maybe its wavelength, E, and amplitude could be measured, but the idea of position becomes nebulous. Heisenberg uncertainty principle: there is a limit to which both the eposition and momentum can be ...

Quantum electrodynamics
In particle physics, quantum electrodynamics (QED) is the relativistic quantum field theory of electrodynamics. In essence, it describes how light and matter interact and is the first theory where full agreement between quantum mechanics and special relativity is achieved. QED mathematically describes all phenomena involving electrically charged particles interacting by means of exchange of photons and represents the quantum counterpart of classical electromagnetism giving a complete account of matter and light interaction.In technical terms, QED can be described as a perturbation theory of the electromagnetic quantum vacuum. Richard Feynman called it ""the jewel of physics"" for its extremely accurate predictions of quantities like the anomalous magnetic moment of the electron and the Lamb shift of the energy levels of hydrogen.
