The Lighter Side of Gravity

Description

Gravity is the most enigmatic of all known basic forces in nature. Yet it controls everything from the motion of ocean tides to the expansion of the entire Universe. Many books use technical jargon and high-powered maths to explain what gravity is all about. In The Lighter Side of Gravity, the presentation is beautifully clear and completely non-technical. Familiar analogies, interesting anecdotes and numerous illustrations are used throughout to get across subtle effects and difficult points. The coverage is, however, comprehensive and makes no compromise with accuracy. This second edition has been brought completely up to date and expanded to include the discovery of gigantic gravitational lenses in space, the findings of the COBE satellite, the detection of MACHOS, the investigations of the very early Universe and other new ideas in cosmology. In short, this lucid and stimulating book presents 'the lighter side' of the intriguing phenomena of 'gravity' to the student and general reader.

'an accessible account of gravity, black holes and the Universe ... A refreshing alternative to the received wisdom.' New Scientist 'For readers who really want to get to grips with the concepts and don't mind a few simple equations (on the level of F=ma), Narlikar's exposition is masterly, a model of clarity and illumination. And it is enlivened wtih many interesting side-lights and touches of humour ... This book is not only full of insights, it is also fun.' Werner Israel, Physics World 'This pocket-sized text on a difficult subject makes good reading (a trip home on the train!) for the general reader.' Irish Astronomical Journal ' ... a refreshing read ... rewards await those who concentrate on its contents.' Quentin Stanley, Journal of the British Astronomical Association ' ... clear and simple explanations of basic gravitational phenomena: it does not try to rush headlong into exotica, but takes time to coax the reader through orbits, motions and the fate of stars.' John D. Barrow, The Observatory
