'''Quantum electrodynamics''' is a modernized theory of [[electrodynamics]] that takes into account the principles of [[quantum mechanics]] and [[special relativity]]. Whereas classical electrodynamics is described in terms of fields and forces — the [[electric field]] and the [[Coulomb force]], specifically — quantum electrodynamics describes all interactions between electrically charged objects in terms of exchanges of [[photons]].
