now been made good by the publication of Pacific Research Centres, a complement to Longman’s existing European Research Centres, Industrial Research in the United Kingdom, and Agricultural Research Centres. This new work lists some 3000 industrial, university, and government institutions within the area which conduct or support scientific research. A qualification for entry is a minimum annual research budget of X50 000: this may seem low, but ensures that significant university laboratories are not excluded. Each entry includes full name (with English translation and acronym where appropriate) and address, together with telephone and telex numbers; names of directors and heads of sections; number of research staff and budget; brief indication of principal activities and publications; and affiliations with other bodies. There is a 23-page subject index and a index of institutions comprehensive arranged alphabetically by title. The 21 countries here catalogued are very disparate, ranging in size from Vanuatu with a single entry and New Caledonia and Kirabati with two each, to China with 274, Australia with 784, and Japan with 1070. While institutions have a fair degree of permanence their staff and research programmes can change quite quickly: it is, therefore, satisfactory to note that updated editions will be produced regularly. Trevor I. Williams Atlas of Historical Eclipse Maps. East Asia 1500 BC-AD 1900. By F. R. Stephenson and M. A. Houlden. Pp. 431. Cambridge University Press. 1986. f40.00 ($79.50).

This is not the first Atlas concerned with eclipses of the Sun. As early as 1887 Theodor von Oppolzer prepared his Canon der Finsternisse, and more recently Jean Meeus and colleagues have prepared tables of superior accuracy. But this new specialised Atlas has specific advantages as far as precision is concerned. In particular, Stephenson and Houlden have taken account of changes in the Earths rotation due to tidal friction and other causes, and the consequent changes in the Moon’s distance which, of course, alters its orbital acceleration. And though these changes are slight, when one goes back far into the past their effects can be significant. Indeed in 1500 BC, the date at which this Atlas begins, neglect of the tidal effects would amount to 12 hours, giving eclipse tracks on the opposite side of the Earth. Because East Asian records of eclipses, both total and annular, are of considerable value for historical and astronomical research, this highly accurate Atlas with its 862 computer-drawn charts full of pertinent

information, all large enough to be useful, to say nothing of its excellent introduction, is an important and useful work. It should surely have a place in many reference libraries. Colin Ronan

Story of the W and 2. By Peter Watkins. Pp. 240. Cambridge University Press. 1986. Hardback f25.00 ($44.501, Paperback f7.95 ($13.95)

cosmic rays uncovered a host of other, equally ‘elementary’, particles and how the development, of high-energy accelerators transformed particle physicists from ‘hunters’ to ‘farmers’. The most recent developments are confined to the final 40 pages. The book is clearly written but is obviously aimed at the serious reader. It would be unsuitable for those with no scientific background and will demand concentration and perseverance from those whose background is limited to high-school physics. The overall impression is that of a good undergraduate textbook from which the equations have been deleted and to which a number of anecdotes (mainly in the form of marginal comments) have been added

Peter Watkins was one of a large group of experimentalists who used the world’s highest energy particle accelerator in the successful search for the W and Z, massive particles predicted by a theory that unifies the weak and electromagnetic forces. The R. Lambourne aim of the book is to give a personal account of this project accessible to scientifically educated laymen.
