【簡介】 The book gives a general introduction to classical theoretical physics, in the fields of mechanics, relativity and electromagnetism. It is analytical in approach and detailed in the derivations of physical consequences from the fundamental principles in each of the fields. This second edition has a new part, namely Classical Field Theory. Highlighting a close connection between this part and earlier parts of the book, where particles, rather than fields are the center of attention. As a general introduction to classical theoretical physics, the book is different from most textbooks at this level, which focus either on classical mechanics or classical electrodynamics but not both. The book will in particular be useful as a textbook for physics courses with such a broader approach to classical physics. For a wider group of students, the book may be of interest for self study. The new inclusion on classical field theory, will give students greater understanding on previous parts of the book, such as examining the Lagrangian formulation of Maxwell's equations with Noether's theorem. This is central in the use of Lagrangian on fields, as also discussed. The text is illustrated with many figures, most of these in color. There are many useful examples and exercises which complement the derivations in the text. 【目錄】 Analytical Mechanics: Generalized Coordinates Lagrange's Equations Hamiltonian Dynamics Relativity: The Four-Dimensional Space-Time Consequences of the Lorentz Transformations Four-Vector Formalism and Covariant Equations Relativistic Kinematics Relativistic Dynamics Electrodynamics: Maxwell's Equations Electromagnetic Field Dynamics Maxwell's Equations with Stationary Sources Electromagnetic Radiation Classical Field Theory: Lagrangian and Hamiltonian Formulations Symmetry Transformations Relativistic Fields

【簡介】 In this new edition of the standard undergraduate textbook on electricity and magnetism, David Griffiths provides expanded discussions on topics such as the nature of field lines, the crystal ambiguity, eddy currents, and the Thomson kink model. Ideal for junior and senior undergraduate students from physics and electrical engineering, the book now includes many new examples and problems, including numerical applications (in Mathematica) to reflect the increasing importance of computational techniques in contemporary physics. Many figures have been redrawn, while updated references to recent research articles not only emphasize that new discoveries are constantly made in this field, but also help to expand readers' understanding of the topic and of its importance in current physics research. New edition of the leading undergraduate textbook on electromagnetism for students in physics and electrical engineering Retains the widely lauded clarity of previous editions, demystifying difficult and subtle mathematical and physical concepts without sacrificing rigor Author is renowned within the physics community for this textbook and Introduction to Quantum Mechanics (Cambridge University Press, 3rd edition 2018) Includes a selection of new problems (and several applied computational problems in Mathematica), worked examples, and updated references to recent research Many figures have been revised or redrawn to provide enhanced pedagogical clarity 【目錄】 1.
