Features: This book organizes its content along the historical development of quantum mechanics, focusing on the coexistence of wave and particle properties of systems, the concept of continuous and discontinuous (i.e., particle and quantum) values of mechanical quantities, and the formation and application of these concepts. Written in a style close to popular science books, it first establishes the overall framework and main lines of thought of quantum mechanics. This approach may better align with readers' cognitive patterns while also providing teachers with flexibility to adapt to different teaching objectives and time constraints. Compared to widely used quantum mechanics textbooks in China, this book emphasizes the explanation of fundamental concepts, principles, and computational methods. Each chapter includes concepts, principles, and thought questions, with particular emphasis on the elaboration of three key concepts—quantum, state, and operator—as well as the seven fundamental principles. It also strengthens the practice of solving eigenvalue equations and calculating commutation relations of operators. Chapters 1 and 2 are dedicated to fundamental concepts and principles, aiming to help readers first establish a clear learning goal and framework for quantum mechanics. Chapters 1–6 present the rigorous theory of non-relativistic quantum mechanics for single particles, while Chapters 7–9 cover applied and advanced content. This book is suitable as a textbook for undergraduate students in science and engineering disciplines, as well as a reference for non-physics majors, graduate students, and various science and technology professionals for self-study and work.
