For studying physics seriously, the Feynman Lectures on Physics are highly recommended for their clear presentation of complex topics. While they can be expensive, they are valuable for committed learners. Additionally, exploring library resources can provide a variety of books that align with personal interests. A solid understanding of calculus, particularly differential equations and vector calculus, is essential for grasping advanced concepts in physics. Overall, a mix of foundational texts and supplementary materials will enhance the learning experience.
