量子力學原理(第2版‧英文版)（簡體書）

Review: `An excellent text....The postulates of quantum mechanics and the mathematical underpinnings are discussed in a clear, succint manner. - American Scientist, from a review of the First Edition Book DescriptionReviews from the First Edition:An excellent text … The postulates of quantum mechanics and the mathematical underpinnings are discussed in a clear, succinct manner. (American Scientist)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. (Physics Bulletin)This massive text of 700 and odd pages has indeed an excellent get-up, is very verbal and expressive, and has extensively worked out calculational details――-all just right for a first course. The style is conversational, more like a co本書是優秀的量子力學教材，內容豐富，結構嚴謹，邏輯性強。作者從所需的數學知識開始，先複習經典力學，再通過一些實驗事實說明經典物理學遇到的困難和引入量子理論的必要性，然後詳細闡述量子力學的基本原理及其進一步應用，給出實際問題的具體解決方法和處理過程。本書敘述簡明易懂，數學推導和例題分析詳細，並附有大量的習題及其答案，是學習量子力學的理想教材。
本書是第２版，作者對第一版內容做了修訂和補充，例如重寫了數學知識簡介部分，新增了時間反演不變性和路徑積分等章節。新增的亮點有：（1）數學知識敘述更加簡潔明瞭；（2）增加了對牛頓力學，拉格朗日力學和哈密頓力學的綜述；（3）物理原理解釋和數學推導兩方面並重，加深讀者對量子理論的理解，提高讀者處理實際問題的能力；（4）較深入地討論了路徑積分及其在現代物理學中的應用。
