In this work, The Theory and Properties of ThermocoupleElements, Professor Pollock has written a singularly usefulmonograph which should appeal to a wide variety of readers, rangingfrom the advanced under-graduate or graduate student who is justbeginning to get his feet wet in this area to the sophisticatedspecialist who wants to brush up on his fundamentals. Moreparticularly, the work provides a worthwhile gathering ofinformation of a theoretical nature on metallic thermocouples.Consider only the topics included: here, under one cover, we findthe history, thermodynamics, mathematics, quantum mechanics, andphysics of thermoelectricity, all neatly compiled and stored forus. A careful perusal of this material is bound to lead to agreater understanding of the behavior of thermoelectric metals interms of the solid state physics involved.
