2Quantum Mechanics is a fascinating but difficult subject. Mathematics is intimidating and intuition hard to find. The popular books do not go into details of the subject and textbooks are just too hard for self-study. This book aims to bridge the gap between the two. The emphasis of this book is to explain the meaning and intuition behind concepts and mathematics. There is extensive use of analogies from daily life to develop visualization and intuition. This book is well suited for a beginner who has limited physics and mathematics background. The material covered is broad, from elementary Quantum Mechanics to Quantum Field Theory. The topics beyond Quantum Mechanics are introduced as well including Supersymmetry and String Theory.
