'... this book is a fine introduction and exposition of many of the theory's features. ... A beautiful approach is taken: the authors show that a consistent theory of electromagnetism can be derived from the simple supposition that there is a force ... I strongly recommend this book for a very wide range of readers. Advanced undergraduates will obtain a good first understanding of GR; postgraduates will find it a useful reference book, and will no doubt learn a great deal that they have not fully covered at undergraduate level. Researchers and lecturers will also find it an invaluable book, not only for recommending to students, but also for obtaining significant new insights themselves.' The Observatory 'What I enjoyed was the clarity. The text was erudite and thorough, and flowed beautifully.... It was clear that students, with diligent application, could work their own way through the text and benefit hugely from self discovery of this fascinating subject.' The Times Higher Education Supplement 'The book is well-written and easy to follow because it is essentially self-contained and every new concept is carefully motivated and justified. Exercises are given at the end of every chapter and numerous examples appear throughout the text.' General Relativity and Gravitation General Relativity is written clearly... gives a good, readable introduction to the foundations and applications of general relativity theory, and it is a good choice for a general relativity course emphasizing astrophysical and cosmological applications. Lawrence H. Ford, Tufts University for Physics Today Like any good book on general relativity, much is expected of the reader, but the writing is concise and elegant, with plenty of good exercises for the student to work on. The authors strike an excellent balance between the demands of mathematical rigor and physical significance. Alan S.McRae, Mathematical Reviews
