From the reviews of the second edition: "It is the book par excellence for the nonrelativist who is at home with mathematics...What gives the book its outstanding quality is Professor Rindler's profound understanding of the ideas behind the formulas ...
and his remarkable ability to share this understanding with the reader. In graceful prose he makes deep things simple. Under his guidance the basic concepts come vividly to life and acquire a force of their own so that the mathematics takes on a secondary role...With its combination of substantial mathematics, insight, and physical down-to-earthedness, the book is a delight in every way."
