'This is an excellent textbook for undergraduate students to learn quantum mechanics. One thing that stands out in this book is the so-called 'spin first' approach: in my teaching experience, using this approach, I was able to introduce the most important concepts and their applications in the first three chapters. This promoted a lot of interest in the underlying physics, and the students were highly motivated to dive into more sophisticated details in later chapters.' Hebin Li, Florida International University
'Quantum Mechanics by David McIntyre is an excellent textbook for teaching undergraduate quantum mechanics. The book forefronts the concepts and postulates of quantum mechanics by starting with two-state systems and using Dirac notation and matrices from the very beginning. My students quickly learn Dirac notation and enjoy working with it. Additionally, I find that using the notation of physicists contributes to a student's own identity as a physicist. The end-of-chapter problems are well thought out and provide many opportunities for students not only to practice, but to sensemake, reflect on their ideas and assumptions, and learn new physics. In addition to being an excellent introduction to quantum mechanics, the book covers advanced topics in a clear manner and many students report finding it to be a useful resource as they continue into graduate school.' Gina Passante, California State University, Fullerton
'McIntyre's spins-first approach to quantum mechanics has been popular with students and faculty for many years at my institution. The text emphasizes the nature of science by grounding the starting topics in experiment. It focuses on meaning and physical sensemaking, not just formalism and symbol manipulation. The educational research base originating from the Oregon State Paradigms program shines through the text - the author is clearly sensitive to common student struggles early on in learning quantum mechanics. The text forefronts the postulates of quantum mechanics, using Dirac notation and relevant (but still reasonably elementary, at first) principles of linear algebra right away. Opportunities for sensemaking are present from the start (e.g., when considering chained Stern-Gerlach experiments, where considerable physical intuition and consistency of outcomes are emphasized). The homework problems are well thought out, and the text builds a solid and modern framework for students progressing to more advanced topics.' Steven Pollock, University of Colorado, Boulder
'McIntyre's spins-first quantum mechanics textbook provides a solid foundation for instructors looking to provide a thoroughly modern approach to the subject. A course based on this text will provide an excellent framework for future study at the graduate level and beyond.' Chandralekha Singh, Distinguished Professor of Physics, University of Pittsburgh, and past President, American Association of Physics Teachers
