The book describes the functioning of the material universe with the use of an intermediate mathematical language and is based entirely on physical phenomena, on reality, and does not use philosophical or theological argumentation based on abstract reasoning not anchored in physical observations.

Jacques Vanier is retired from the National Research Council of Canada and as adjunct professor in the Physics Department at the University of Montreal, Canada. He is a fellow of the Royal Society of Canada, the American Physical Society, and the Institute of Electrical and Electronic Engineers. He has written more than 120 journal articles and proceedings papers and is the author of several books on masers, lasers, and atomic clocks, addressing the physics involved in the functioning of that type of instrumentation. His main research work is oriented toward the understanding and physical application of quantum electronics phenomena.
