infinite in the equations of electromagnetics, since in these equations
represents the velocity of light. But then all the terms in these equations in which
entered as denominator would disappear. Since these terms are those responsible for induction, in a world in which the velocity of light was infinite, no such phenomenon as induction could exist. There would be no dynamos, no radio; in fact, there would be no light rays, since light is itself a phenomenon of electromagnetic induction. Obviously such a world would not be the one in which we live.
Summarising, we must say that in classical science the velocity of light
is finite and that the invariant velocity is infinite. In relativity,
