= Lorentz covariant

{synonym}

Same motivation as <Galilean invariance>, but <relativistic> version of that: we want the laws of physics to have the same form on all inertial frames, so we really want to write them in a way that is Lorentz covariant.

This is just the relativistic version of that which takes the <Lorentz transformation> into account instead of just the old <Galilean transformation>.
