Quote: "In particle physics, quantum electrodynamics (QED) is the relativistic quantum field theory of electrodynamics."
Quantum mechanical theory that combines electromagnetism and quantum mechanics.
Quote: "It describes how light and matter interact."
Quote: "It is the first theory where full agreement between quantum mechanics and special relativity is achieved."
Quote: "QED mathematically describes all phenomena involving electrically charged particles interacting by means of exchange of photons."
Quote: "It represents the quantum counterpart of classical electromagnetism."
Quote: "It gives a complete account of matter and light interaction."
Quote: "QED...described light and matter beyond the wave-particle duality proposed by Einstein in 1905."
Quote: "Richard Feynman called it 'the jewel of physics.'"
Quote: "Extremely accurate predictions of quantities like the anomalous magnetic moment of the electron and the Lamb shift of the energy levels of hydrogen."

Quote: "QED can be described as a very accurate way to calculate the probability of the position and movement of particles."
Quote: "QED can be described as a very accurate way to calculate...even those massless such as photons."
Quote: "The quantity depending on position (field) of those particles."
