This book establishes the concept that all existing or possible crystal systems can be derived from a single universal principle, and their characteristics are nothing more than the consequences of this principle. This concept drives the author to search for a universal classification system for crystal forms that can extend to any crystal structure observed or yet to be discovered. This search begins with an examination of symmetry, the most general property of crystal forms. The author posits that any two directions within a crystal can be designated as equal if a rotation of the crystal will make any two faces parallel that were initially parallel to those two directions. This is symmetry. The author further proposes that if a rotation of 180 degrees about an axis will make two faces parallel that were initially parallel to the same face, then that axis is a symmetry axis. The book explores these principles and more, ultimately using the universal principle of equal directions to define 32 distinct crystal groups. This text is a valuable resource for students of crystallography and the history of crystallography, as well as anyone interested in the relationship between mathematical principles and physical phenomena. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…
