74How to become a Theoretical Physicist : A Textbook List for the Standard Physics Curriculum
A Textbook List for Undergraduate Physics - I here present a list of textbooks for the physics student. It is a compilation of books usually considered as being the “standard” or “classic” texts in physics. The motivated student can then begin a self-study of undergraduate level physics or get started for an upcoming course.
