Black Hole Entropy: From Shannon to Bekenstein
... For the particle entropy, it is numerically equal to maximum entropy ln 2 if the chances of the particle existing or not are both equal to 1/2. Hence it was not clear if the Shannon formula was capable of giving the BH entropy. Also it is important to note, (as was stressed by Bekenstein [2]), a qua ...

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.
