Current recommendations for Modern Physics textbooks at the upper undergraduate and graduate levels emphasize the need for resources that align with top-tier university standards. While Beiser's "Concepts of Modern Physics" is noted, it may be too elementary for advanced studies. David Tong's lecture notes from the University of Cambridge are highlighted as exceptionally informative, often surpassing traditional textbooks. Tong also provides a list of recommended textbooks at the start of his lectures, which can serve as valuable resources for deeper understanding in areas such as Relativity, Quantum Mechanics, Nuclear Physics, and Particle Physics.
