This text gives students a clear and easily understood introduction to entropy - a central concept in thermodynamics, but one which is often regarded as the most difficult to grasp. Professor Dugdale first presents a classical and historical view of entropy, looking in detail at the scientists who developed the concept, and at how they arrived at their ideas. This is followed by a statistical treatment which provides a more physical portrait of entropy, relating it to disorder and showing how physical and chemical systems tend to states of order at low temperatures. Dugdale includes here a brief account of some of the more intriguing manifestations of order in properties such as superconductivity and superfluidity.; "Entropy and Its Physical Meaning" also includes a number of exercises which can be used for both self- learning and class work. It is intended to provide a complete understanding of the concept of entropy, making it valuable reading for undergraduates in physics, physical sciences and engineering, and for students studying thermodynamics within other science courses such as meteorology, biology and medicine.
The theory of how metals conduct electronically had for a long time
been confined to metals that are crystalline with the constituent
atoms in regular arrays. The discovery of how to make solid
amorphous alloys led to an explosion of measurements of the
electronic properties of these new materials, and the emergence of
a range of interesting low temperature phenomena. This 1995 book
describes in physical terms the theory of the electrical
conductivity, Hall coefficient, magnetoresistance and thermopower
of disordered metals and alloys. The author begins by showing how
conventional Boltzmann theory can be extended and modified when the
mean free path of the conduction electrons becomes comparable with
their wavelength and interionic separation. The consequence of this
is explored and the theory tested by application to experimental
data on metallic glasses. Designed as a self-contained review, the
book will appeal to non-specialist physicists, metallurgists and
chemists with an interest in disordered metals.
