The Nature, Origin, and Interpretation of the Etch Figures on Crystals

Abstract

IT is probably evident to many others besides specialists how greatly the science of crystals has lately progressed by the introduction of the X-ray method. Brilliantly created some fifteen years ago by Laue, and simplified and developed by Sir William and W. L. Bragg, the method early led to convincing deductions of the atomic arrangements within certain crystals; and almost immediately was also applied by Moseley to the elucidation of the atom itself. After a marked pause due to the War, the method has been systematically developed in many directions, not least actively in its original role as a crystal probe. The purely crystal development has in fact been so rapid that a general halt is now recognisable, not in the number of workers or of their results, but in the kind of results. It is probably true to say that there has been no advance in principle for the last three years.
