This comprehensively revised - essentially rewritten - new edition of the 1990 edition (described as "e;extremely useful"e; by MATHEMATICAL REVIEWS and as "e;understandable and comprehensive"e; by Scitech) guides readers through the dense array of mathematical information in the International Tables Volume A. Thus, most scientists seeking to understand a crystal structure publication can do this from this book without necessarily having to consult the International Tables themselves. This remains the only book aimed at non-crystallographers devoted to teaching them about crystallographic space groups. - Reflecting the bewildering array of recent changes to the International Tables, this new edition brings the standard of science well up-to-date, reorganizes the logical order of chapters, improves diagrams and presents clearer explanations to aid understanding- Clarifies, condenses and simplifies the meaning of the deeply written, complete Tables of Crystallography into manageable chunks- Provides a detailed, multi-factor, interdisciplinary explanation of how to use the International Tables for a number of possible, hitherto unexplored uses- Presents essential knowledge to those needing the necessary but missing pedagogical support and detailed advice useful for instance in symmetry of domain walls in solids
