"What this monograph suggests is that experiments be done to measure the time it takes for a ray of light to travel from A to B without undergoing reflection, interference, refraction or any other internal rearrangement, and to similarly measure the time from B to A. In order to entertain the possibility of a difference in the transit times, between AB and BA it is necessary to propose or suggest what changes would be required in the Lorentz transformation equations and the transformation of Maxwell's equations. The monograph was designed to meet this goal. It was also designed to thrust into the arena of discussion the axiom defining time as presented in the Special Theory of Relativity."--BOOK JACKET.
