05366063183 -Turkey/Denizli Quantum electrodynamics (QED) is a
relativistic quantum field theory of electromagnetism. QED
mathematically describes all phenomena involving electrically
charged particles interacting by means of the electromagnetic
force, whether the interaction is between light and matter or
between two charged particles. It has been called "the jewel of
physics" for its extremely accurate predictions of quantities
like the anomalous magnetic moment of the muon, and the Lamb
shift of the energy levels of hydrogen. 1 Physical

interpretation of QED In classical physics, light is observed to
take the quickest path between two points; but how does light
`know where it's going'? That is, if the start and end points
are known, the path that will take the shortest time can be
calculated. However, when light is first emitted, the end point
is not known, so how is it that light always takes
