Electromagnetic theory is a fundamental subject in physics, and there has been a long-standing need for a standard textbook that provides a concise summary of its basic principles and illustrates them with practical examples. Prof. William R. Smythe's textbook fills this need by directly relating the theory of electricity and magnetism to research problems. The book is well-structured, with a detailed index and appendix comparing different unit systems. It uses vector notation throughout and includes an introduction to relativity and wave mechanics. The mathematical analysis is developed as needed, with references to integral tables for simpler results. The book is highly practical, providing results in a form suitable for research. The reviewer has found the book to be very useful since its publication. It is recommended as an essential resource for researchers in electromagnetic theory. Dr. Surendranath Dasgupta's third volume of "A History of Indian Philosophy" continues the excellent work of the first two volumes. It focuses on the religious philosophy of southern Indian schools, which are not orthodox in relation to Brahmin thought. The volume discusses various schools, including the Pañcavātras, Bhaskara, Visistadvaita, and Nimbarka. It also includes a detailed exposition of selected Puranas and bibliographies. The analysis of these teachings highlights the depth and alertness of Indian thought. The discussion of time and other philosophical issues shows the closeness of Indian views to some Western doctrines. This volume is an important contribution to the study of Indian philosophy.Electromagnetic theory is a fundamental subject in physics, and there has been a long-standing need for a standard textbook that provides a concise summary of its basic principles and illustrates them with practical examples.
