This new edition of A concise dictionary of physics contains over 2500 entries covering commonly encountered terms and concepts in physics, and key terms from mathematics, astrophysics, metallurgy, electronics, and physical chemistry. Many new terms have been included, particularly in the fields of nuclear and particle physics, quantum theory and solid-state physics. The entries are written in a clear and explanatory style to provide both straight-forward definitions and background information. This approach, combined with a cross-referencing system, enables the reader to place each entry in a broader scientific context. Line drawings are included whenever the meaning of a word can best be conveyed by means of a diagram and a range of tables of scientific information is provided.
