"Principles of Quantum Mechanics" (book by R. Shankar)

"Principles of Quantum Mechanics" by R. Shankar explores how the universe at tiny scales behaves differently from our everyday experience. It explains concepts like particles acting as both particles and waves, uncertainty in their properties, and how they exist in multiple states simultaneously. The book covers the fundamental rules—called principles—that govern these behaviors, providing a logical framework to understand phenomena like atomic structures and quantum interactions. It presents complex ideas with clarity, balancing mathematical rigor with accessible explanations, making it a valuable resource for readers seeking a deeper, yet understandable, grasp of quantum physics.
