Abstract
Maxwell?s equations of electrodynamics are only special-case formulae of more generalized equations published in 1892 by Heinrich Hertz. Maxwell?s equations were derived for scenarios involving a stationary detector. Consequently, only a partial time derivative was taken, and so the measured current density was equal to the current density measured at the source. An important implication of Hertz? invariant, general equations of electrodynamics is that there is no space-time symmetry.
