Abstract For nearly 60 years the book “Theory of Dislocations” by John P. Hirth and Jens Lothe has been the authoritative reference on the theory of dislocations. The reputation of the book was that it was not for the feint of heart. Rather it was widely considered to be the authoritative reference to be consulted only after the reader had started with more elementary books on dislocations like “Introduction to Dislocations” by Derek Hull and David J. Bacon or “Elementary Dislocation Theory” by Johannes and Julia R. Weertman. More recently the book by Wei Cai and William D. Nix, “Imperfections in Crystalline Solids” has provided an intermediate introduction to dislocations as a bridge between the more elementary books just cited and the book by Hirth and Lothe, which was written for experienced researchers. Now, with the Third Edition of “Theory of Dislocations,” with Peter M. Anderson as the lead author, the classic book by Hirth and Lothe has been made much more assessible to a wider audience of students and researchers. Without sacrificing any of the rigor found in the first two editions of “Theory of Dislocations,” the Third Edition provides a much more tutorial approach to understanding and appreciating the theory of dislocations.

Amiya Kumar Bagchi, an eminent economist of the modern Cambridge tradition, has produced a timely treatise, in a condensed form, on the development problems of the Third World countries. The author's general thesis is that economic development in the developing societies necessarily requires a radical transformation in the economic, social and political structures. As economic development is actually a social process, economic growth should not be narrowly defined as the growth of the stock of rich capitalists. Neither can their savings be equated to capital formation whose impact on income will presumably 'trickle down' to the working classes. Economic growth strategies must not aim at creating rich elites, because, according to the author, "maximizing the surplus in the hands of the rich in the Third World is not, however, necessarily a way of maximizing the rate of growth".

The external surface of a material has an atomic or molecular structure that is different from the bulk material. So does any internal interface within a material. Because of this, the energy of a material or any grain or particle within it increases with the curvature of its bounding surface, as described by the Gibbs-Thomson equation. This chapter explains how surfaces control the nucleation of new phases during reactions such as solidification and precipitation, the coarsening and growth of particles during heat treatment, the equilibrium shape of crystals, and the surface adsorption and segregation of solutes and impurities. The Gibbs-Thomson was predated by a number of related equations; it is not clear whether it is named after J. J. Thomson or William Thomson (Lord Kelvin); and it was not put into its current usual form until after Gibbs’, Thomson’s and Kelvin’s time. J. J. Thomson was the third Cavendish Professor of Physics at Cambridge University. He discovered the electron, which had a profound impact on the world, notably via Thomas Edison’s invention of the light bulb, and subsequent building of the world’s first electricity distribution network. William Thomson was Professor of Natural Philosophy at Glasgow University. He made major scientific developments, notably in thermodynamics, and he helped build the first trans-Atlantic undersea telegraph. Because of his scientific pre-eminence, the absolute unit of temperature, the degree Kelvin, is named after him.
