Universal Newton Time in Classical Electrodynamics: Elements of Physical Interpretation
G. A. Kotel\'nikov
It is shown that the universal time of Newton can be introduced into classical electrodynamics. This possibility results from the existence within Maxwell equations of a generalized symmetry with respect to Galilei transformations. In the case of the extended Galilei transformations, the postulate of invariant speed of light can be made compatible with the concept of Newtonian universal time. Some physical consequences of the extended Galilei symmetry are considered.
