商品描述

Unlike most textbooks on electromagnetic theory, which treat electricity, magnetism, Coulomb's law and Faraday's law as almost independent subjects within the framework of the theory, this well-written text takes a relativistic point of view in which electric and magnetic fields are really different aspects of the same physical quantity.
Suitable for advanced undergraduates and graduate students, this volume offers a superb exposition of the essential unity of electromagnetism in its natural , relativistic framework while demonstrating the powerful constraint of relativistic invariance. It will be seen that all electromagnetism follows from electrostatics and from the requirement for the simplest laws allowable under the relativistic constraint. By means of these insights, the author hopes to encourage students to think about theories as yet undeveloped and to see this model as useful in other areas of physics.
After an introductory chapter establishing the mathematical background of the subject and a survey of some new mathematical ideas, the author reviews the principles of electrostatics. He then introduces Einstein's special theory of relativity and applies it throughout the rest of the book. Topics treated range from Gauss's theorem, Coulomb's law, the Faraday effect and Fresnel's equations to multiple expansion of the radiation field , interference and diffraction, waveguides and cavities and electric and magnetic susceptibility.
Carefully selected problems at the end of each chapter invite readers to test their grasp of the material. Professor Schwartz received his Ph.D. from Columbia University and has taught physics there and at Stanford University. He is perhaps best known for his experimental research in the field of high-energy physics and was a co-discoverer of the muon-type neutrino in 1962. He shared the 1988 Nobel Prize in Physics with Leon M. Lederman and Jack Steinberger.

商品描述(中文翻譯)

與大多數關於電磁理論的教科書不同,這本寫得很好的書籍採取了相對論的觀點,將電力、磁力、庫倫定律和法拉第定律視為理論框架內幾乎獨立的主題。在這個相對論的框架下,電場和磁場實際上是同一物理量的不同方面,這本書適合高年級本科生和研究生閱讀,以其自然的相對論框架提供了對電磁學基本統一性的出色闡述,同時展示了相對論不變性的強大約束力。可以看到,所有的電磁學都源於靜電學和在相對論約束下允許的最簡單法則的要求。通過這些見解,作者希望鼓勵學生思考尚未開發的理論,並將這個模型視為物理學其他領域有用的工具。

在介紹了主題的數學背景和一些新的數學思想後,作者回顧了靜電學的原則。然後,他介紹了愛因斯坦的特殊相對論並在整本書中應用了它。所涉及的主題包括高斯定理、庫倫定律、法拉第效應和菲涅爾方程,以及輻射場的多重展開、干涉和繞射、波導和腔體以及電磁感應和磁化率。

每章末尾精心挑選的問題邀請讀者測試他們對材料的理解。Schwartz教授在哥倫比亞大學獲得博士學位,並在那裡和斯坦福大學教授物理學。他可能最為人所知的是他在高能物理領域的實驗研究,並於1962年與Leon M. Lederman和Jack Steinberger共同發現了μ型中微子。他與他們共同獲得了1988年的諾貝爾物理學獎。
