On the Physics of Crystals. Part I

Abstract

This review on the physics of crystals is divided into a number of parts. The first parts deal with the experimental aspects of the problem of the solid state. In the last part a general solution of this problem will be proposed and developed. The experimental facts which distinguish the solid state, particularly those which have not been explained on the basis of the theory of ideal crystallographic lattices will be selected. It is our contention that these obnoxious observations are peculiar to the solid state and to incorporate them into the theory constitutes the present problem of the solid state.
