    Quantum Better advanced Quantum Mechanics book than Sakurai?

    Sakurai's Modern Quantum Mechanics is 1/2 of a very good graduate textbook. Unfortunately Sakurai passed away midway through writing it, and it is very obvious exactly where it swapped from their writing to just using their notes. The back half of the book, while by no means bad, is notably less...

    Astrophysics Looking for an Advanced Introduction to Astrophysics text

    I'm a physicist familiar with QM, QFT and GR etc but I've never really sat down and learned astrophysics properly. Would Steven Weinberg's new book be considered a good advanced introduction or would people recommend another text. Half tempted to get it anyway to complete the Weinberg collection.
