| Book | Best For | Style | | :--- | :--- | :--- | | | Conceptual Understanding | Narrative, rigorous, physics-integrated. | | H.K. Dass | Exam Prep / Engineering | Formula-heavy, recipe-based, easy to pass exams with. | | Mary L. Boas | Undergrad Physics Standard | Comprehensive, standard textbook for physics majors worldwide. | | Arfken & Weber | Graduate Physics | The "Bible" of math physics, but often drier and more encyclopedic. | | Sadri Hassani | Math Physics | Very rigorous, bridges the gap to pure math very well. |
The official PDF is elusive (and legally gray to share). But the heart of the book—Balakrishnan’s teaching—is freely available on NPTEL. Start there, then buy the ebook if you need the polished, problem-solved reference.
