Hi everyone. I'm currently at the second year to get a bachelor degree in physics. I'm not getting quantum mechanics classes yet, but I love physics since I was about 12 years old, so I started studying it on my own. I already know those things on introductory QM, like solving the Schrodinger equation for different situations. I'm actually reading (when I have enough time) Sakurai, Modern Quantum Mechanics and I'm finding that book very interesting. I find the theory easier to understand than it's in other books. The book don't have a indication of what it's intended for (undergraduate students or graduate, etc..). My questions are 1 - what level the book may be considered? And 2 - will I need more books on the theory of QM throughout my academic life? if so, could you list some of them (i.e. some of the most common books that are used in universities for graduate courses) Please excuse my poor English.
