In the discussion about preparing for the Physics Olympiad, participants emphasize the importance of selecting the right study materials. Key recommendations include "Fundamentals of Physics" for foundational knowledge, "Irodov's Problems in General Physics" for advanced problem-solving skills, and the "Feynman Lectures" for conceptual understanding. The consensus is that while "Fundamentals of Physics" covers essential theory, it may not delve deeply into advanced topics like quantum physics or electromagnetic waves, which are also necessary for Olympiad preparation. MIT lectures by Lewin are highlighted as a valuable resource for visual learning. Participants suggest that completing all odd-numbered problems in "Fundamentals of Physics" is crucial for mastery. They also recommend practicing past Olympiad questions and engaging with problem books to enhance skills. Overall, a strong grasp of calculus is deemed necessary for tackling most physics problems effectively.
