Unabridged republication of the edition published by Interscience Publishers, Inc., New York, 1961.
The Theory of Relativity by R. K. Pathria Graduate-level text elaborates on physical ideas underlying relativity, examining special theory (space-time transformations, four-dimensional formulations, mechanics, optics, electromagnetism), and general theory (space-time continuum, gravitation, experiments, and relativistic cosmology). 1974 edition.
A Sophisticate's Primer of Relativity: Second Edition by P. W. Bridgman Geared toward readers already acquainted with special relativity, this book answers natural questions: What is a frame of reference? A "law of nature"? The role of the "observer"? 1983 edition.
The Unity of the Universe by D. W. Sciama This accessible approach uses compelling photos, figures, and examples to address and answer profound questions about the universe. "An engrossing book, an invigorating intellectual exercise." — Scientific American. 1959 edition.
