Books on relativity cover a wide spectrum of styles. At one end are the turgid formal tomes, full of tensors, which convey little physical insight and are extremely unexciting. At the other are the popular accounts for the layman which aim to propagate one of the wonders of the twentieth century, but contain very few equations. So where in between should one write for the instruction of an undergraduate? The author of this book knows exactly where he stands, having been himself subjected to an over-mathematical teaching, with lamentable lack of excitement. He has therefore adopted the approach of developing the subject with maximum interest and minimal mathematics. In this he succeeds admirably. Whether this is the best way to teach relativity is a matter of personal opinion. An undergraduate with reasonable mathematical competence might prefer the elegance of more formal methods of proof of such results, but, at the same time, he is in danger of losing insight by being buried in the algebra. The ideal - at least for some - would be a formal book, with an `interest' book as essential background reading. However, this would be time consuming, since the latter, with carefully expounded arguments, can be as demanding on the IQ as a formal textbook. But for those wanting an `interest' book, the one reviewed here is most recommendable. There are quotations from Aristotle through Galileo to Einstein, interspersed with some imaginative artwork by the author's brother. The coverage of the usual topics of elementary special relativity is full, and there are numerous problems, including solutions. In the first major chapter, the author starts from basics (inertial frames, Michelson-Morley experiment). By simple arguments and thought experiments, he produces all the well-known results (time dilation, length contraction, etc). It is only at this point that the Lorentz transformations appear. The following chapter on the geometry of space and time is somewhat more formal, and includes Minkowski diagrams, 4-vectors and the Doppler effect. The chapter on general relativity and cosmology is absorbing. Worth mentioning in passing is the summary of the general theory: `Matter tells space how to bend; space tells matter how to move'. Familiar exposition follows of the experimental evidence supporting the general theory, together with discussion of possible universes. Matters of more recent interest, such as pulsars, black holes and gravitational waves are included. One might have thought that a book in which the Lorentz transformations do not appear until page 111 would have little to say quantitatively about general relativity, but this is not the case. It surprised this reviewer to discover what can be achieved with simple physics: for instance, the resolution of the twins paradox and the explanation of the 'factor of 2' in the deflection of light by a star. And did you know that the radius of curvature of space-time at the Earth's surface is m (about 9 light-minutes)? If not, read this book and find out.
