Quantum Mechanics- central not only to physics but also chemistry, materials science and other fields- is notoriously abstract and difficult. Essential Quantum Mechanics is a uniquely concise and explanatory book that fills the gap between introductory and advanced courses, between popularizations and technical treatises. By focusing on the fundamental structure, concepts and methods of quantum mechanics this introductory yet sophisticated work emphasizes both physical and matehmeatical understanding. A modern perspective is adopted throughout-the goal in part, being to gain entry into the world of "real" quantum mechanics, as used by practicing scientists. With over 60 original problems, Essential Quantum Mechanics is suitable as either a text or a reference. It will be invaluable to physics students as well as chemists, electrical engineers, philosophers, and others whose work is impacted by quantum mechanics, or who simply wish to better understand this fascinating subject.

Why? Because in this book you will find the fundamentals and the structure of quantum mechanics explained directly and clearly, with you in mind, without the naive tone of those common popularizations centered on the "weirdness of the quantum", nor the atoms, molecules and complicated physical systems of comprehensive textbooks, so focused on the applicability of the theory."-- Mathematical Reviews A concise, lucid development of the fundamental structure of quantum mechanics from a thoroughly modern perspective.
