From the reviews"[It] is a pleasure to read and distraction to review. The book provides a comprehensive and thorough explication of current cosmology at a level appropriate for a beginning graduate student or an advanced and motivated undergraduate. It covers all relevant concepts of cosmology and pertinent general relativity and contains a significant number of exercises, with solutions to a sample set. This book clearly is the result of the refining of notes from a course on cosmology#x2B26; It provides a summary of current observations and mathematical underpinnings of the physical principles. This is an extremely valuable contribution in the field, which has been changing rapidly as a result of new technology and new theoretical motivations from the related field of high-energy physics#x2B26; This book provides a good look at the intellectual effort and a solid foundation for the new discoveries soon to come." (Physics Today, September 2002)"All these exciting developments are laid out in a very accessible form in this textbook especially written for senior undergraduates or graduates from various backgrounds. It deals in a very nice and explicit form with the basic ideas of cosmology and general relativity (.).

This is a fine textbook and would be very enjoyable for private study. (The Physicist, 2001).
