If you're looking for Hans C. Ohanian's book, I found that he is the author of "Classical Electrodynamics" and other physics books. If you provide more context or clarify which book you're interested in, I'll do my best to help.
Style and accessibility Ohanian’s exposition is concise and often dense; readers with a solid background in undergraduate physics and mathematics will gain the most. The book is more compact than multi-volume tomes, which is an advantage for focused courses or self-study, but some topics are treated more tersely and may require supplemental reading. ohanian hans c. principles of quantum mechanics pdf
While not as widely used as Griffiths (for undergrads) or Shankar/Sakurai (for grads), Ohanian’s Quantum Mechanics is a respected, if somewhat overlooked, text. Its strength is bridging the gap for students who find Griffiths too terse but Shankar too formal. If you're looking for Hans C
