The language of science continues to grow at an astounding rate. When Isaac Asimov's book, Words of Science, was published in 1959, term such as "quasar," "laser," and "transfer RNA" were not included; since they were not yet a part of the common scientific vocabulary. More Words of Science takes up where the earlier volume left off and provides the reader with 250 more clearly and interestingly written explanations. Very often, books of this sort are useful only as references; by contrast, More Words of Science is so well written that many people will want to read it cover to cover. The book is not a dictionary of science terms. Each word is given a page-long narrative which goes considerably beyond the minimum. Drawn from all fields of science, the terms and their explanatory essays are thoroughly indexed. Cross-references have been avoided, however, in order to do away with the annoyance of flipping from one page to another. More Words of Science can be highly recommended to general readers who seek a pleasant and non-threatening introduction to a broad spectrum of words from the language of science.
