Meanings
-
(uncountable) The phenomena associated with moving electric charges, and their interaction with electric and magnetic fields; the study of these phenomena.
Some of the most beautiful and thus appealing physical theories, including quantum electrodynamics and quantum gravity, have been dogged for decades by infinities that erupt when theorists try to prod their calculations into new domains. Getting rid of these nagging infinities has probably occupied far more effort than was spent in originating the theories.
