This comprehensive and well-written book provides a thorough understanding of the principles of modern physics, their relations, and their applications. Most of the developments in physics that took place during the twentieth century are called "modern"-something to be treated differently from the "classical" physics. This book offers a detailed presentation of a wide range of interesting topics, starting from the special theory of relativity, basics of quantum mechanics, atomic physics, spectroscopic studies of molecular structures, solid state physics, and proceeding all the way to exciting areas such as lasers, fibre optics and holography. An in-depth treatment of the different aspects of nuclear physics focuses on nuclear properties, nuclear models, fission, fusion, particle accelerators and detectors. The book concludes with a chapter on elementary interactions, symmetries, conservation laws, the quark model and the grand unified theory. Clear and readable, this book is eminently suitable as a text for B.Sc. (physics) course.
