This text offers a comprehensive, thorough presentation of modern physics. It is distinguished from other texts in the field by its clear and accessible presentation. Sandin introduces each new topic with relevant examples and uses numerous analogies throughout to clarify difficult concepts. There are over 250 in-text worked examples, and over 1100 end-of-chapter problems. In addition to the standard topics of modern physics, the text includes material on cosmology, the Big Bang theory, and grand unified theories.

This text presents a summary of the basic theoretical structures of classical mechanics, electricity and magnetism, quantum mechanics, statistical physics, special relativity and modern field theories.

Our understanding of the physical world was revolutionized in the twentieth century — the era of “modern physics''. This book, aimed at the very best students, presents the foundations and frontiers of today's physics. It focuses on the following topics: quantum mechanics; applications in atomic, nuclear, particle, and condensed-matter physics; special relativity; relativistic quantum mechanics, including the Dirac equation and Feynman diagrams; quantum fields; and general relativity. The aim is to cover these topics in sufficient depth such that things “make sense'' to students and they can achieve an elementary working knowledge of them. Many problems are included, a great number of which take dedicated readers just as far as they want to go in modern physics. Although the book is designed so that one can, in principle, read and follow the text without doing any of the problems, the reader is urged to attempt as many of them as possible. Several appendices help bring the reader up to speed on any additional required mathematics. With very few exceptions, the reader should then find the text, together with the appendices and problems, to be self-contained.

Essentials of Modern Physics Applied to the Study of the Infrared covers topics about the essentials of modern physics. The book starts with the situation of research into the infrared and the problems to which it gives rise, and then discusses instrumentation in the infrared: optics, sources, receivers and electronics. The book describes the interaction between the infrared and matter within the framework of Lorentz's general theory and in the particular case of solids using Born's theory and introducing the notion of phonons. The region of the electromagnetic spectrum and the developments in science and industry, including X-ray analysis, molecular beam experiments, radio, and television are considered. The book tackles the sources of infrared as well as infrared detectors. The text will be useful to physicists, engineers, and laboratory technicians.
