Title: Unified physics
Description: The life work of R. I. Gray, published in 1988, on the unification of physics, summarized by this excerpt from the book's preface:

From a largely extra-mural study of this subject since 1936, it appeared that significant progress towards unification might be facilitated by a broad-based analysis/synthesis linking the physics of the zero-point, 'vacuum' or aether background to the fundamental particles and cosmology, in an embodiment of Mach's Principle. By exploiting the fact that physics is overdefined by overlapping, complementary theories, it is shown that there is a unifying set of length/mass/temperature scale relationships that include the well-known Large Cosmic Numbers but extends to the Hubble parameter, the cosmic background radiation (CBR) and the rest mass spectra of the photon and the graviton. Using well-established and quantal theories, such an approach to a program of unification has been developed.
