Up for sale is my “Principles of Quantum Mechanics” hardcover textbook by R. Shankar. I purchased this textbook new in 2008 when I started self-studying quantum mechanics. I used it very lightly for about 6 months in 2015 when I was studying for the physics preliminary exam, and it has been on my bookshelf ever since. I think it’s time to find it a new home. Please take a look at the photos carefully and be sure to ask any questions you may have before purchasing. I am selling this book as-is is with no returns accepted. I will very carefully package this book to protect it from the ordinary and expected rigors of shipping. Shipping will be by USPS Media Mail (slow but inexpensive). I’ve set the shipping cost calculator charge whatever the shipping label costs me.
