Reflecting the continually growing vocabulary in science, the Concise Science Dictionary has made a wealth of terms encountered in all of the scientific disciplines accessible to non-scientists and scientists alike. The New Scientist praised it as "an essential book." Now, derived from that invaluable work, these three newly expanded dictionaries each focus on one particular branch of science. Written in a clear and explanatory style, the entries in each provide both straightforward definitions and invaluable background information. This approach, combined with an extensive cross-referencing system, enables readers to place each entry in a broader context. Each dictionary contains a range of tables containing essential scientific information and line drawings whenever the meaning of a word can best be conveyed by means of a diagram. The new edition of A Concise Dictionary of Biology contains over 2,500 entries on commonly encountered terms and concepts in biology, biophysics, and biochemistry, and key terms from medicine and palaeontology. It also contains many new terms in genetics (including genetic engineering), molecular biology, and immunology, taking into account the recent advances in these fields. The new edition of A Concise Dictionary of Chemistry contains over 3,000 entries on commonly encountered terms and concepts in chemistry, physical chemistry, and biochemistry. It also includes many new terms which reflect recent advances in techniques, concepts, and materials. The new edition of A Concise Dictionary of Physics contains over 2,700 entries on commonly encountered terms and concepts in physics and key terms from mathematics, astrophysics, metallurgy, electronics, and physical chemistry. It also includes many new terms encountered in the fields of nuclear and particle physics, quantum theory, and solid-state physics. Anyone seeking concise and accurate definitions of words encountered in biology, chemistry, or physics will find each of these dictionaries indispensable.
