 <​blockquote>​I would suggest that you don't do any preliminary reading, and just learn QM directly. There is not much to it, the requisite background is very primitive linear algebra, and Dirac'​s book "The Principles of Quantum Mechanics"​ and Feynman'​s "​Lectures on Physics Vol III" can be read with Wikipedia help without any prerequisites. <​blockquote>​I would suggest that you don't do any preliminary reading, and just learn QM directly.

-The classical mechanics you need to know is not very sophisticated either--- you just need to know Newton'​s laws, and how they come from a Lagrangian or Hamiltonian,​ which is covered in standard sources. You don't need so much deep stuff, although knowing Poisson brackets is handy for seeing the vestigial quantumness in the classical mechanics structure.+The classical mechanics you need to know is not very sophisticated either--- you just need to know Newton'​s laws, and how they come from a Lagrangian or Hamiltonian,​ which is covered in standard sources.

 It is usually a waste of time to try to go through prerequisites,​ as these are usually boring and most of the material doesn'​t end up getting used. For QM, you need to come in knowing what a matrix is, and what an eigenvalue is, which is probably best learned from Dirac. It is usually a waste of time to try to go through prerequisites,​ as these are usually boring and most of the material doesn'​t end up getting used.

 +<​blockquote>​For quantum mechanics, the original is still the best: 
 + 
 +  * Dirac'​s "The Principles of Quantum Mechanics"​. 
 + 
 + 
 +It's clear, it's terse, and it's comprehensive. All other books take most of their material from this source. 
 + 
 +For a basic short introduction to quantum mechanics, you can't beat: 
 + 
 +  * [[http://​www.feynmanlectures.caltech.edu/​III_toc.html|Feynman Lectures on Physics Vol III]] 
 + 
 +This is very good and intuitive, and complementary to the remaining books. 
 + 
 +Landau and Lifschitz "​Quantum Mechanics"​ 
 +is heavy on good exercizes and mathematical tools. L&L include topics not covered everywhere else. The standard undergraduate books on quantum mechanics are not very good in comparison to these, and should not be used. 
 + 
 +A book which requires minimum of calculus or continuous mathematics is 
 + 
 +  * Nielsen & Chuang: "​Quantum Computation and Quantum Information"​ 
 + 
 + 
 +This focuses on modern research, and discrete systems in quantum computation. If you don't know calculus, learn it, but you might find this book the most accessible. It's long though. 
 + 
 +On advanced quantum mechanics, there are good books are by Gottfried and by Sakurai. Berezin'​s book is also a great classic. 
 + 
 +For the path integral, you can read Feynman and Hibbs, but I like Feynman'​s 1948 Reviews of Modern Physics article more. There is also a good book which covers the path integral: 
 + 
 +Yourgrau & Mandelstam: Variational Principles in Classical and Quantum Physics. 
 +The original source for the Fermionic path integral is still the best, in my opinion: 
 + 
 +  * D.J. Candlin: [[https://​link.springer.com/​article/​10.1007%2FBF02745446|Il Nuovo Cimento 4 no. 2, 231 (1956)]] 
 + 
 + 
 +If you want to convince yourself quantum mechanics is necessary, you should recapitulate the historical development. For this, the following source is good: 
 + 
 +Ter Haar's "The Old Quantum Theory"​ (it's short) to learn Bohr Sommerfeld quantization 
 +You can also read the Wikipedia page on [[https://​en.wikipedia.org/​wiki/​Old_quantum_theory|old quantum theory]] for a sketchy summary, then look at the page on [[https://​en.wikipedia.org/​wiki/​Matrix_mechanics|matrix mechanics]]. This explains the intuition Heisenberg had about matrix elements, something which is not in Dirac'​s book or anywhere else. Heisenberg'​s reasoning is also found to certain extent in the first chapters of this book: 
 + 
 +Connes "​Noncommutative geometry"​. 
 +This book is also very interesting for other reasons.<​cite>​Ron Maimon (https://​physics.stackexchange.com/​users/​4864/​ron-maimon),​ What is a good introductory book on quantum mechanics?, URL (version: 2015-10-02):​ https://​physics.stackexchange.com/​q/33260</​cite></​blockquote>​
