Julian Seymour Schwinger (February 12, 1918 – July 16, 1994) was an American theoretical physicist. He is best known for his work on the theory of quantum electrodynamics, in particular for developing a relativistically invariant perturbation theory, and for renormalizing QED to one loop order.

The book gives a streamlined introduction to quantum mechanics and describes the basic mathematical structures underpinning it. From the reviews: "This book is an introduction to the mathematics of quantum mechanics...The strength of the book is where it shows how the mathematical treatment of quantum mechanics brings insights to physics...It will be useful to the experienced ...(展开全部)

Reviews 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 s...(展开全部)

在线阅读本书 Beginning students of quantum mechanics frequently experience difficulties separating essential underlying principles from the specific examples to which these principles have been historically applied. Nobel–Prize–winner Claude Cohen–Tannoudji and his colleagues have written this book to eliminate precisely these difficulties. Fourteen chapters provide a clarity of org...(展开全部)

Simple enough for students yet sufficiently comprehensive to serve as a reference for working physicists, this classic text is celebrated for its clarity and coherence of presentation as well as the author’s fluid and literate style. Subjects include a detailed treatment of formalism and its interpretation, an analysis of simple systems, symmetries and invariance, methods of ap...(展开全部)

"The standard work in the fundamental principles of quantum mechanics, indispensable both to the advanced student and to the mature research worker, who will always find it a fresh source of knowledge and stimulation." --Nature "This is the classic text on quantum mechanics. No graduate student of quantum theory should leave it unread"--W.C Schieve, University of Texas
