Abstract

THE complex structure of modern physics has caused many obscurities and inaccuracies to creep into the formulation of its epistemological presuppositions. Even the cosmological value of the principles and equations of relativity is difficult to extricate clearly from the mass of speculations, dimensional and non-dimensional, to which they have given rise. In undertaking a clarification of the confused conditions of theoretical physics, Prof. Mackaye has performed a very useful task; and this he does by providing critical answers to a number of pertinent questions such as the following: What is the cause of gravitation? Is matter a form of radiation? What is the cause of the Lorentz contraction? Why are not material bodies retarded in their motion through space? Has the theory of relativity superseded the law of causation? Is the acceleration of material bodies relative exclusively to other material bodies?
