BOOK REVIEW C e n e ~ Dleflmmry of Pbysks, Market House Books Ltd--Oxford University Press. US$16.95. £7.95. This dictionary of nearly 300 pages is derived from the Concise Science Diet~nary (OUP 1984) and comprises the physics entries therein as well as extra entries from astrophysics, physical chemistry, mathematics and other sciences. Companion volumes are Concise Dictionary of Chemistry and Concise Dictionary of Biology. The entries at about 10 per page total approximately 3000 and appear to cover an immense range of physical terms with s~mple ~___*~_-n'_'ptionsor definitions which in the fimited space available can be extremely useful especially to those active in adjacent fields of science, or to remind one of definitions and relationships. Under radiation for example two clearly differentiated definitions are given in terms of energy in the form of elm waves or photons, and of a stream of particles, especially alpha or beta particles. Other
entries are radiation pressure, radiation temperature, radiation units. Radiation collision is defined as a collision between chargedparticlesin which part of the kinetic energy is radiated in the form of photons. Many items are crossreferenced. The Appendices comprise short tables; base and supplementary S.I. units; derived S.I. units with special names; decimal multiple names; conversion of other units to S.I. units; fundamental constants; information on the solar system. These helpful tables could well be extended in future editions without infringing on far more massive volumes of Physical and Chemical Constants. A useful book to Imve at one's side when reading or writing review articles or papers on less familiar topics. Perhaps a paper-backed version would he well received by a wider readership. A.C.
