Classical Electromagnetism via Relativity One of the arts of teaching is to attack a problem from a different point of view, if the conventional approach has not been fully appreciated. This often helps the class to appreciate the conventional approach more fully. Maxwell's equations are generally introduced during a long course on electromagnetism, in which the correct interpretations and experimental bases of Maxwell's equations are sometimes obscured by the large amount of time of necessity devoted to the important applications of individual laws. The displacement 'current' is often introduced in a way that gives the wrong impression of its role in contemporary electromagnetic theory. There have been refinements of interpretation since Maxwell's time, particularly following the abandonment of the ether theories and the introduction of the theory of relativity. This is particularly true of the displacement 'current'. In this monograph, Maxwell's equations are approached from a different point of view from the conventional approach, namely using Coulomb's law and the transformations of the theory of special relativity. This approach illustrates the essential unity of Maxwell's equations, and the modern interpretation of the various terms in Maxwell's equations. It is the reverse of the historical approach, since the theory of special relativity arose out of optics and electromagnetism. Buy Premium To Support Me & Get Resumable Support & Max Speed
Bernard Schutz, "Gravity from the Ground Up: An Introductory Guide to Gravity and General Relativity" English | ISBN: 0521455065 | 2003 | 483 pages | PDF | 10 MB This book invites the reader to understand our Universe, not just marvel at it. From the clock-like motions of the planets to the catastrophic collapse of a star into a black hole, gravity controls the Universe. Gravity is central to modern physics, helping to answer the deepest questions about the nature of time, the origin of the Universe and the unification of the forces of nature. Linking key experiments and observations through careful physical reasoning, the author builds the reader's insight step-by-step from simple but profound facts about gravity on Earth to the frontiers of research. Topics covered include the nature of stars and galaxies, the mysteries of dark matter and dark energy, black holes, gravitational waves, inflation and the Big Bang. Suitable for general readers and for undergraduate courses, the treatment uses only high-school level mathematics, supplemented by optional computer programs, to explain the laws of physics governing gravity.
