**Please can an administrator move this to the "Maths and Physics Learning Materials" section- I can't post there for some reason. Thank you!** Hello, I am interested in learning some more technical Quantum Mechanics, and was wondering how accessible the Peskin and Schroeder textbook is as it seems to be the most popular on university courses. Does it show you how to derive important results in step-by-step detail, or is the reader required to fill in lots of gaps? Is it significantly easier/harder than other textbooks on QFT? Is it very abstract or does it link back to lots of physical examples? How good is it for self-study? What level of physics knowledge does it assume? Do I need to be familiar with any extra maths not taught at undergraduate level? Thank you for any advice.
