Helo all. This is my first message in the forum, although I have been reading it for some months. I am self studying physics, I have some background on electromagnetism, since I am a Telecommunication engineer. Nowadays, I am refreshing my knowledge on classical mechanics (with Taylor's book), and on EM (with Griffiths' book), and when I am done, I would like to begin with special relativity and quantum mechanics. For SR, it seems that there is consensus about the best books to begin with (Taylor-Wheeler, French, Rindler), but not about the best first book on QM. I would really appreciate if you could suggest me a good book to begin with QM (Grriffiths, Zettili, Ballentine, Shankar...?). Thank you all so much.
