Book Synopsis Infinite-Space Dyadic Green Functions in Electromagnetism by : Muhammad Faryad
Download or read book Infinite-Space Dyadic Green Functions in Electromagnetism written by Muhammad Faryad and published by Morgan & Claypool Publishers. This book was released on 2018-08-13 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: In any linear system, the input and the output are connected by means of a linear operator. When the input can be notionally represented by a function that is null valued everywhere except at a specific location in spacetime, the corresponding output is called the Green function in field theories. Dyadic Green functions are commonplace in electromagnetics, because both the input and the output are vector functions of space and time. This book provides a survey of the state-of-the-art knowledge of infinite space dyadic Green functions.

Book Synopsis Beyond Einstein's Unified Field by : John Brandenburg, Ph.D.
Download or read book Beyond Einstein's Unified Field written by John Brandenburg, Ph.D. and published by SCB Distributors. This book was released on 2011-08-07 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Veteran plasma physicist John Brandenburg reveals the new theory that finally accomplishes what Einstein failed to do: the GEM Unification Theory proves the mathematical and physical interrelation of the forces of gravity and electromagnetism! This theory vindicates Einstein's dedication to unifying the fields in the final labor of his life. His quest became legendary, then mythic, until the whole idea was dismissed as myth by other physicists; the gravity-electromagnetism problem pursued by Einstein until his death became regarded like the ancient Greek problem of squaring the circle-an epic puzzle with no solution. But the other physicists were wrong, as Brandenburg shows. It turns out the fields can be unified-the circle can be squared-and this has vast implications for the future of humankind. Brandenburg starts out by tracing the evolution of thought on the two long-term forces of nature, gravity and electromagnetism, from ancient times to the modern day. He shows the intricate interweaving of Einstein's work with that of other physicists, including Sarkharov and his "zero point” theory of gravity and the hidden fifth dimension of Kaluza and Klein. He also traces the surprising, hidden influence of Nikola Tesla on Einstein's life. This book shows how, despite Einstein's errors in the details, the successful GEM Unification Theory is built on his basic hypothesis that gravity and electromagnetic forces could be unified, and that both controlled gravity and a new view of the cosmos follow: hydrogen, the basic building block of the universe, can be unified with the vacuum itself! The universe is self-renewing, a sort of "evergreen cosmos.” Brandenburg describes control of space-time geometry through electromagnetism, and states that faster-than-light travel will be possible in the future. Anti-gravity through electromagnetism is possible, which upholds the basic "flying saucer” design utilizing "The Tesla Vortex.” A must read for any person interested in UFOs and leading-edge physics.

Book Synopsis Unification of Electromagnetism and Gravity by : Selwyn E Wright
Download or read book Unification of Electromagnetism and Gravity written by Selwyn E Wright and published by WestBow Press. This book was released on 2014-02 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a Unification of Electromagnetism and Gravity, author Selwyn Wright describes his New Relativity (NR) theory in a simple physical way, in order to help the lay person to understand. At the same time he seeks to update aspects of modern physics in a rigorous manner. NR removes confusion in Einstein's relativity, simplifies our understanding of the universe and challenges relativity as a more logical and comprehensive theory. Motional electromagnetic (EM) and gravitational theories are shown to have two inherent deficiencies that have prevented them from becoming a unified theory. Firstly they do not recognize that the propagation medium (ether) is the essential thread that runs through these developments. Secondly they do not realise that EM waves and gravity are two forms of the same field - unsteady electric and steady difference electric fields. Wright's new theory re-establishes a preferred frame of reference and restores the connection between classical and modern physics. It also forges new links between electrical sources and observers in motion and between electric fields and gravity. As explained in the Unification of Electromagnetism and Gravity the medium provides the bridge between the Lorentz transform, accelerating frames and gravity, providing a basis for the unification theory of the universe.

This book was released on 1996-12-03 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: "We owe Clerk Maxwell the precise formulation of the space-time laws of electromagnetic fields. Imagine his own feelings when the partial differential equations he formulated spread in the form of polarized waves with the speed of light! This change in the understanding of the structure of reality is the most profound and fruitful that has come to physics since Newton."--Albert Einstein

Book Synopsis Gauge Fields, Knots, and Gravity by : Associate Professor Department of Mathematics John C Baez
Download or read book Gauge Fields, Knots, and Gravity written by Associate Professor Department of Mathematics John C Baez and published by World Scientific Publishing Company Incorporated. This book was released on 1994 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an introduction to the basic tools of mathematics needed to understand the relation between knot theory and quantum gravity. The book begins with a rapid course on manifolds and differential forms, emphasizing how these provide a proper language for formulating Maxwell's equations on arbitrary spacetimes. The authors then introduce vector bundles, connections and curvature in order to generalize Maxwell theory to the Yang-Mills equations. The relation of gauge theory to the newly discovered knot invariants such as the Jones polynomial is sketched. Riemannian geometry is then introduced in order to describe Einstein's equations of general relativity and show how an attempt to quantize gravity leads to interesting applications of knot theory.
Book Synopsis Space-time-matter by : Paul S. Wesson
Download or read book Space-time-matter written by Paul S. Wesson and published by World Scientific. This book was released on 2007 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Albert Einstein, together with Theodor Kaluza and Oskar Klein, realized that extra dimensions can be used to unify the different fields of physics, as well as unifying the fields with their material sources. In fact, it was Einstein's dream to transpose the a base wooda of the matter term in his field equations to the ?marble? of the geometrical term. During his lifetime, this kind of unified theory achieved only partial success. But the modern approach, outlined in this bestseller, is elegant and agrees with all the classical tests. The basic idea is to unify the source and its field using the rich algebra of higher-dimensional Riemannian geometry. In other words, space, time and matter become parts of geometry."

Book Synopsis Deformed Spacetime by : Fabio Cardone
Download or read book Deformed Spacetime written by Fabio Cardone and published by Springer Science & Business Media. This book was released on 2007-09-04 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a detailed discussion of the mathematical aspects and physical applications of a new geometrical structure of space-time, based on a generalization ("deformation") of the usual Minkowski space, as supposed to be endowed with a metric whose coefficients depend on the energy. This new five-dimensional scheme (Deformed Relativity in Five Dimensions, DR5) represents a true generalization of the usual Kaluza-Klein (KK) formalism.
Book Synopsis Advanced Classical Electromagnetism by : Robert Wald
Download or read book Advanced Classical Electromagnetism written by Robert Wald and published by Princeton University Press. This book was released on 2022-03-22 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This is a concise, beginning graduate-level textbook on classical electromagnetism, the branch of physics that describes the interaction of electric currents or fields and magnetic fields. Electromagnetism (also called electrodynamics) is one of the pillars of modern physics and, as such, of the modern physics curriculum, with courses on electromagnetism required at the undergraduate and graduate levels. These courses traditionally proceed in a quasi-historical fashion, starting from equations and laws that were first formulated in the eighteenth and nineteenth centuries and still form the foundations of our understanding of electromagnetism. However, as Robert Wald argues, teaching in this way can be imprecise and tends to promote outdated ways of thinking about the subject. This book rethinks how electromagnetism is presented at the graduate level, offering a corrective that aims to bring teaching up to date with our more modern understanding of the topic. The book begins by debunking four common misconceptions, or "myths," that can hinder a deep conceptual understanding of electromagnetism. Wald then proceeds through the major topics first-year grad courses (and textbooks) in electromagnetism typically cover, including electrostatics, dielectrics, magnetostatics, electrodynamics, geometric optics, special relativity, gauge theory, and point charge. Wald's aim throughout is to explain to students how to think about electromagnetism from a modern and mathematically precise perspective, formulating all the key conceptual ideas and results in the field clearly and concisely, while forgoing extensive collections of examples and applications. The book could be used as the basis for or as a supplement to a course, or for self-study by students seeking a deeper understanding than traditional courses and books offer"--

Download or read book Electrodynamics written by William Baylis and published by Springer Science & Business Media. This book was released on 2004-01-12 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emphasis in this text is on classical electromagnetic theory and electrodynamics, that is, dynamical solutions to the Lorentz-force and Maxwell's equations. The natural appearance of the Minkowski spacetime metric in the paravector space of Clifford's geometric algebra is used to formulate a covariant treatment in special relativity that seamlessly connects spacetime concepts to the spatial vector treatments common in undergraduate texts. Baylis' geometrical interpretation, using such powerful tools as spinors and projectors, essentially allows a component-free notation and avoids the clutter of indices required in tensorial treatments. The exposition is clear and progresses systematically - from a discussion of electromagnetic units and an explanation of how the SI system can be readily converted to the Gaussian or natural Heaviside-Lorentz systems, to an introduction of geometric algebra and the paravector model of spacetime, and finally, special relativity. Other topics include Maxwell's equation(s), the Lorentz-force law, the Fresnel equations, electromagnetic waves and polarization, wave guides, radiation from accelerating charges and time-dependent currents, the Liénard-Wiechert potentials, and radiation reaction, all of which benefit from the modern relativistic approach. Numerous worked examples and exercises dispersed throughout the text help the reader understand new concepts and facilitate self-study of the material. Each chapter concludes with a set of problems, many with answers. Complete solutions are also available. An excellent feature is the integration of Maple into the text, thereby facilitating difficult calculations.

Book Synopsis Spacetime: Minkowski's Papers on Spacetime Physics by : Hermann Minkowski
Download or read book Spacetime: Minkowski's Papers on Spacetime Physics written by Hermann Minkowski and published by . This book was released on 2020-03-20 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Not only the general public, but even students of physics appear to believe that the physics concept of spacetime was introduced by Einstein. This is both unfortunate and unfair. It was Hermann Minkowski (Einstein's mathematics professor) who announced the new four-dimensional (spacetime) view of the world in 1908, which he deduced from experimental physics by decoding the profound message hidden in the failed experiments designed to discover absolute motion. Minkowski realized that the images coming from our senses, which seem to represent an evolving three-dimensional world, are only glimpses of a higher four-dimensional reality that is not divided into past, present, and future since space and all moments of time form an inseparable entity (spacetime). Einstein's initial reaction to Minkowski's view of spacetime and the associated with it four-dimensional physics (also introduced by Minkowski) was not quite favorable: "Since the mathematicians have invaded the relativity theory, I do not understand it myself any more." However, later Einstein adopted not only Minkowski's spacetime physics (which was crucial for Einstein's revolutionary theory of gravity as curvature of spacetime), but also Minkowski's world view as evident from Einstein's letter of condolences to the widow of his longtime friend Besso: "Now Besso has departed from this strange world a little ahead of me. That means nothing. People like us, who believe in physics, know that the distinction between past, present and future is only a stubbornly persistent illusion." Besso left this world on 15 March 1955; Einstein followed him on 18 April 1955. This volume contains Hermann Minkowski's four works, which laid the foundations of spacetime physics: Space and Time, The Relativity Principle, The Fundamental Equations for Electromagnetic Processes in Moving Bodies and A Derivation of the Fundamental Equations for the Electromagnetic Processes in Moving Bodies from the Standpoint of the Theory of Electrons. These papers have never been published together either in German or English and the second and the last paper have not been translated into English so far.
Book Synopsis A Spacetime Theory of Matter, Electromagnetism, and Gravitation by : Celestino John Gaeta
Download or read book A Spacetime Theory of Matter, Electromagnetism, and Gravitation written by Celestino John Gaeta and published by Createspace Independent Pub. This book was released on 2014-01-01 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: A six-dimensional spacetime with three temporal and three spatial dimensions, that is naturally perceived as a spacetime with one temporal and three spatial dimensions, allows both quantized-spacetime and freespacetime environments that do not exhibit singularities. Physical constraints imposed by the solutions avoid closed time loops for matter. Maxwell's equations, with the correct signs, are simply a subset of the equations resulting from setting the Ricci tensor elements equal to zero, and account for the presence of electric charge. The absence of observed magnetic charge is also explained. The equations that result from setting the diagonal Ricci tensor elements equal to zero, along with the equations-of-motion, yield solutions that describe thenucleus and the electronic structure of atoms, including spin and intrinsic magnetic moments. The solution for the nucleus explains the nature of mass and allows for calculation of nuclear size and mass consistent with experimental observations. Anti-matter, neutron mass being slightly larger proton mass, proton-to-neutron conversion within a nucleus, and instability of the neutron outside the nucleus are all naturally part of thesolution to the differential equations describing the spacetime. In the quantized spacetime description of the electronic structure of atoms, the Ricci tensor equations involving the diagonal elements of the Ricci tensor combine to form a Schrodinger equation leading to quantization of the speed of light in the spacetime. Using this result in Maxwell's equations produces an equation for photon frequency that is identical to the result from quantum theory for a hydrogen-like atom (effects of spin are not considered here), governed by a set of integer parameters identical to the quantum numbers. The expression for the energy of photons that are emitted or absorbed by this spacetime is obtained by matching curvature components between free and quantizedspacetime environments, resulting in a linear relationship between the energy and frequency of the photons. Furthermore, the solution is shown to conform to the Pauli exclusion principle so that Fermi-Dirac statistics apply. All of these features follow from requiring the Ricci tensor to be zero in six dimensions, matching curvature components between quantized spacetime and free spacetime at the hypersurfaces, and by applying the equations-of-motion.
