Hello everyone I know that they are many threads already on this topic, but i'm still not convinced. I'm currently taking a course in modern physics, and, as i thought i would be, I'm fascinated with QM. Why i'm studyin engineering and not physics is something i don't have clear. Anyway, my courses us the Eisberg-Resnick book, so it's quite introductory. So what should be my next step? something rigorous, but with a introduction on the math formalism (i'm quite blind in bra kets). I was thinking of Townsend "A moder approach to Quantum Mechanics", but i need a little more background i think, i am right? My math background is four courses of analysis (real and complex calculus, DE) and two courses of linear algebra. Regards and thanks in advance.
