Optically Anomalous Crystals Optically Anomalous Crystals begins with an historical introduction covering the contributions of Brewster Biot Mallard Brauns Tamman and many other distinguished crystallographers. From this follows a tutorial in crystal optics. Further chapters discuss the two main mechanisms of optical dissymmetry: 1. the piezo optic effect and 2. the kinetic ordering of atoms. The text then tackles complex inhomogeneous crystals and the complex optical properties resulting from the superposition of anomalies having various etiologies. The book treats the literature comprehensively but uses illustrations from the authors laboratories as the subjects of detailed analyses.This is an invaluable text for crystallographers mineralogists and petrologists interested in the growth of minerals and synthetic crystals and their optical properties. It is also ideally suited to students of optical mineralogy professional scientists and engineers as well as historians of science.
