"The aim of this book is to demonstrate that using "Conventional Wisdom" and "Conventional Logic", classical physics can explain all the observed phenomena attributed to relativity. The arbitrary principles of Einstein's relativity are thus useless. It is very important to recognize the fundamental importance of the principle of mass-energy conservation. It took thousands of years of development for scientific thought to finally reject the magic of witchcraft. During the nineteenth century, scientists became convinced that matter cannot be created from nothing. Conversely, matter cannot be destroyed into nothing. It seems that even Einstein believed this, since he is the one who, at the beginning of the twentieth century, introduced the equation E = mc2 implying mass-energy conservation. However, he later developed general relativity which is not compatible with that principle.^

Indeed, according to Straumann, the: "general conservation law of energy and momentum does not exist in general relativity". Twentieth century science moved backward in accepting again the magical creation of matter or energy from nothing, even if this is hidden in complicated mathematics. Contrary to what Einstein did, all the demonstrations in this book are compatible with the principle of mass-energy and momentum conservation. Using classical mechanics, we demonstrate that length contraction is a real physical phenomenon. We examine how this leads to the Lorentz equations. Then, we show how classical principles are sufficient to explain the advance of the perihelion of Mercury and derive Einstein's equation. The fundamental reason for this advance is illustrated with a classical apparatus. We also study the Lorentz transformations in three dimensions and the Doppler phenomenon.^

Then we see how the problems brought by the relativity of simultaneity and by the principle of equivalence can be explained using conventional logic. We also show how classical mechanisms produce perturbations in the internal structure of atoms and molecules. Finally, we show that the presence of intense gravitational potentials leads to degenerate matter corresponding to Schwarzschild's black holes."--Preface, page 11.
