To effectively learn quantum physics, a solid mathematical background is essential, particularly in areas such as differential equations, matrix algebra, and imaginary numbers. While popular science books like "How to Teach Quantum Physics to Your Dog" by Chad Orzel can provide an introductory understanding, they often lack the depth needed for a comprehensive grasp of the subject. Classical mechanics knowledge is also crucial. Recommended resources include "The Theoretical Minimum" by Susskind for foundational concepts, "The Structure and Interpretation of Quantum Mechanics" by Hughes for a more structured approach, and "Quantum Mechanics: A Modern Development" by Ballentine for deeper insights. For those seeking advanced mathematical perspectives, "Geometry of Quantum Theory" by Varadarajan is suggested, though it is considered highly complex. Overall, while popular treatments can be engaging, they should be supplemented with rigorous study to fully understand quantum physics.
