Abstract

(1) THOSE who had the opportunity of hearing Prof. Nernst deliver his short course of lectures at University College, London, on the Quantum Theory as applied to the solid state of matter will welcome this somewhat belated publication. The book is a masterpiece of lucid condensation, covering as it does in a small number of pages the whole range of modern work on the thermal properties of solids. The limitations of the Dulong Petit generalisation are briefly discussed. The necessity for the introduction of some new hypothesis in place of equipartition is made clear, and the fortunate application of Einstein of the Planck quantum concept to the heat capacity of vibrating atoms is shown to point the way to a new understanding of the baffling problem of the solid state. The Nernst Lindemann empirical modification of the Einstein formula is touched upon, and later the more theoretically significant expression of Debye. (1) The Theory of the Solid State.
