Principles of Quantum Mechanics is a textbook by Ramamurti Shankar.

[2][3][4] Physics Bulletin said about the book, "No matter how gently one introduces students to the concept of Dirac’s bras and kets, many are turned off.

Shankar attacks the problem head-on in the first chapter, and in a very informal style suggests that there is nothing to be frightened of".

[5] American Scientist called it "An excellent text … The postulates of quantum mechanics and the mathematical underpinnings are discussed in a clear, succinct manner".
