With each new edition the book has expanded and been brought up to date; in this edition particular attention has been given to revising and updating the physics entries (especially the particle physics). In addition the coverage of life sciences has been considerably broadened.
The many new entries reflect developments in science over the past five years. The dictionary provides a reliable and clear explanation of the basic vocabulary of physics and chemistry, with a fair coverage of the words used in mathematics, astronomy and biology. All numerical information is given in SI units.
As a student's handbook and for the specialist outside his or her own field, this dictionary remains an indispensable aid; for the general reader it provides an up-to-date guide to the numerous scientific and technical words that are now so much a part of our daily life.
