In a world where religion is either frozen cold or exploding into flames, Christians and Muslims of good will must be ready to stand side by side. But mutual recognition must be hard-headed and sober, based on respect that grows out of firm understanding of the other's otherness: hence the need for this book. Here, Albert Walters takes Christians through fourteen centuries of Islamic history, the fundamentals of Muslim belief and practice, and the vivid diversity that makes up the Islamic world. He opens windows to show significant differences between Islam and Christianity, and helps the interested reader to make the first step of understanding and appreciation. Building on this, he deftly examines the history of Islam in his country Malaysia, and then discusses the difficulties between Christians and Muslim with realism and due concern for all the misapprehensions and misgivings that haunt moves to come closer together. At the end, he provides hints of how closeness can be attempted through systematic cooperation and the pre-requirement of respect and esteem for what is different. This book deserves to be read carefully by Christians who are concerned about impaired interfaith relationships, and to be studied by those who try to see God in the other, and also by those who do not.

This textbook represents a new approach in the teaching of quantum physics. The first seven chapters present nonrelativistic quantum mechanics and its interpretation as well as perturbations and scattering theory. They include Dirac's and Feynman's formalisms. The chapter on symmetry treats gauge transformations, too. The quantum theory of angular momentum includes the isospin of leptons and quarks. It uses as a new tool the graphical spin algebra. The second part of the book is devoted to quantum fields: Boson fields including Higgs fields, Dirac's theory of Fermion fields, quantum electrodynamic and quantum chromodynamics. A brief review is appended to raise the students' interests in quantum cosmology. The readers will also find many detailed worked examples and many problems to test their own understanding.

"Serious scientists, working off of theories, first developed by Einstein and his colleagues seventy years ago, have been investigating the phenomenon known as "entanglement," one of the strangest aspects of the strange universe of quantum mechanics.". "According to Einstein, quantum theory required entanglement - the idea that subatomic particles could become inextricably linked, and that a change to one such particle would instantly be reflected in its counterpart even if a universe separated them. Einstein felt that if the quantum theory could produce such incredibly bizarre effects then it had to be invalid. But new experiments in both the United States and Europe show not only that it does happen, but that it may lead to unbreakable codes and even teleportation."--BOOK JACKET.

This second edition of Exercises in Quantum Mechanics has been much revised, updated and enlarged in order to cater more comprehensively for the growing need of students of quantum mechanics to have a better insight and grasp of this fascinating but mathematically convoluted branch of physics. The number of illustrative problems solved has been increased from 114 to 228, and new exercises have been added to each of the chapters. The problems discussed have been carefully chosen so as to involve a minimum of technical complexity whilst emphasising the consequences of the quantum-mechanical formalism. Various chapters have been extended significantly and three new chapters are included to make this volume more complete and sophisticated in its coverage of elementary quantum mechanics, principally by including material dealing with angular momentum coupling and tensor algebra. The presentation of the material has also been made much more attractive. This revised edition will be especially useful to advanced undergraduate and graduate students of quantum mechanics and to all teachers of this subject.
