So far I got: Griffiths => easy, ok it's not so easy,not really what I ment, but it covers the basics without going much into the real deeper algebraïc stuff, emphasis on calculus, that's what I mean with easy, I mean a decent, solid book for undergraduate level. But suppose I tackle Griffiths and I want a deeper understanding after that, what book should I read then. Shankar? Sakurai? That book from Dirac? Cohen-Tannoudji Vol 1? If I complete at least one of these, and I want to take a grasp on beginning Relativistic QM or maybe QFT. Or a different direction and Quantum Entanglement /Quantum Information or Path Integral formulation, what should I do then? Oh, and most beginning books, they say: let's take an Hamiltonian that is not time-dependent, what if the Hamiltion is time dependent, what books should I read then?
