Introduction to Quantum Mechanics

[higgsnerd137]

One of my friends has wanted to learn an introduction to quantum mechanics for a while. What books would any of you say as a good book for this?

Claude Cohen-Tannoudji, Bernard Diu, Frank Laloe "Quantum Mechanics" (2 vol. set)

This didactically unrivalled textbook and timeless reference by Nobel Prize Laureate Claude Cohen-Tannoudji separates essential underlying principles of quantum mechanics from specific applications and practical examples and deals with each of them in a different section. Chapters emphasize principles; complementary sections supply applications. The book provides a qualitative introduction to quantum mechanical ideas; a systematic, complete and elaborate presentation of all the mathematical tools and postulates needed, including a discussion of their physical content and applications.
The book is recommended on a regular basis by lecturers of undergraduate courses.
