Newton's theory of gravitation is the grandest and the most enduring physical theory ever created. Today, more than 300 years after it was first conceived, Newton's theory of gravitation is still the basic working theory of astronomers and of all the scientists dealing with space exploration and celestial mechanics. However, Newton's theory of gravitation has serious defects: it is incapable of accounting for certain fine details of planetary motion; it does not provide any information on the temporal aspect of gravitational interactions; it cannot be reconciled with the principle of causality and with the law of conservation of momentum. This book extends and generalizes Newton's theory of gravitation, makes it free from the above defects, and provides a large variety of methods for calculating gravitational interactions between moving or stationary bodies of all shapes, sizes and configurations. The starting point of the generalization of Newton's theory of gravitation developed in this book is the idea that gravitational interactions are mediated by two force fields: the gravitational field proper created by all masses and acting upon all masses, and the "cogravitational" field created by moving masses only and acting upon moving masses only. In accordance with the principle of causality, the two fields are represented by retarded field integrals, which, for static or slowly-varying gravitational systems, yield the ordinary Newtonian gravitational field. An immediate consequence of the generalized Newtonian theory of gravitation developed on this basis is that gravitational interactions normally involve at least five different forces associated with velocities, accelerations and rotations of interacting bodies. The effects of these forces are quite remarkable. Some examples: a fast-moving mass passing a spherically-symmetric body causes the latter to rotate; a mass moving with rapidly-decreasing velocity exerts both an attractive and a repulsive f

<p>This textbook of electromagnetic theory, written for an advanced undergraduate course, is characterized by its pedagogical excellence and by an abundance of novel material, problems, and illustrative examples based on the author's original research and on his contributions to Maxwell's theory of electric and magnetic phenomena. Among the many unique and novel features of the book are: author's solutions of Maxwell's equations (now referred to in the scientific literature as the "Jefimenko's equations"), a comprehensive treatment of vector-analytical operations involving retarded field integrals, a detailed discussion of electric fields outside current-carrying conductors, spectacular line-of-force photographs of electric fields inside and outside current-carrying media, calculations of electric and magnetic fields from charge and current inhomogeneities, a remarkably simple derivation of Maxwell's stress integrals, the "thin shell" atomic model, Minkowski's equations for moving media, electromagnetic effects affecting space crafts moving through interplanetary or interstellar magnetic fields, a detailed analysis of Poynting's energy flux in and out a cylindrical conduit, the method of "equivalent currents," etc., etc. The presentation is clear, logical, thorough and thought-provoking. Employing the time-independent Maxwell's equations as the starting point, the theory is developed from the beginning on the basis of the Faraday-Maxwell concept of electric and magnetic fields. A generalization to the time-dependent Maxwell's equations is effortless and lucid. Vector analysis is introduced early in a self-contained chapter and is then used throughout the text as a standard mathematical tool. The exposition is purposeful and efficient. Careful distinction is made between the definitions, laws and consequences. The range of validity and the limitations of applicability of all the electric and magnetic laws are clearly stated. The book is written for the student and is designed to encourage a creative application of electromagnetic theory. For this purpose numerous carefully selected illustrative examples have been incorporated in the text and an excellent collection of problems has been supplied with each chapter. The format of the book is designed for easy readability. The book is set in the famous British Baskerville typeface, which is one of the most readable typefaces in existence. The format is further enhanced by numerous meticulously executed air-brush drawings. The book is printed on acid-free Fortune Matte paper and is bound in high grade "artificial leather" cloth. The book contains 598 pages of main text in 16 chapters, 544 problems, 243 illustrative examples, 249 figures, 12 plates of lines-of-force photographs and 10 tables. The DUST JACKET is no longer available, and is therefore not included.</p>
