Book Description
This book explores the fundamental but often overlooked connection between Maxwell's equations, as they are taught in undergraduate electrical engineering courses, and special relativity. Written for an audience of practicing engineers instead of theoretical physicists, it exposes the underlying contradictions brought about by the emergence of electromagnetic theory, one of the greatest triumphs in mathematical physics of all time that unified the phenomena of electricity, magnetism, and light, into a world in which the classical Galilean principle of relativity was thought incontrovertible. It explains how Einstein redefined the concepts of space and time and what it means to measure them, while altogether disbanding the notion of global simultaneity. A manifestly relativistic formulation of electromagnetic laws is first presented and then applied to common engineering problems, like the interaction of electromagnetic fields at dynamic interfaces, the derivation of propagating modes in closed metal waveguides, and the foundations of microwave network theory. Mathematical toolkits for relativistic analysis, such as tensor notation and spacetime algebra, are explained. These tools are then used to analyze the consequences of motion at relativistic speeds upon otherwise well-known electromagnetic circuit behaviors. Well-drawn and insightful diagrams along with articulate explanations help the reader to gain an intuitive understanding of four-dimensional spacetime and the nature of the electromagnetic field in that context, while summary tables and comprehensive appendices serve as a resource for further self-directed exploration. Readers trained in microwave engineering will learn to see their field from a new perspective, and shall gain from that new insight the ability to conceive of unexpected solutions to practical engineering problems that might otherwise defy one's intuition.

Book Description
Annotation Classical field theory is employed by physicists to describe a wide variety of physical phenomena. These include electromagnetism, fluid dynamics, gravitation and quantum mechanics. The central entity of field theory is the field which is usually a multi component function of space and time. Those multi component functions are usually grouped together as vector fields as in the case in electromagnetic theory and fluid dynamics, in other cases they are grouped as tensors as in theories of gravitation and yet in other cases they are grouped as complex functions as in the case of quantum mechanics. In order to know the value of the field one needs to solve a set of coupled partial differential equations with given boundary and initial conditions. The book covers a selection of recent advances in classical field theory involving electromagnetism, fluid dynamics, gravitation and quantum mechanics. Advances in Classical Field Theory will benefit readers by saving them the effort to read through numerous journal articles which would be needed to obtain a coherent picture of classical field theory otherwise. The book is unique in its aim and scope and is not similar to any existing publication.

Book Description
There exist essentially two levels of investigation in theoretical physics. One is primarily descriptive, concentrating as it does on useful phenomenological approaches toward the most economical classifications of large classes of experimental data on particular phenomena. The other, whose thrust is explanatory, has as its aim the formulation of those underlying hypotheses and their mathematical representations that are capable of furnishing, via deductive analysis, predictions - constituting the particulars of universals (the asserted laws)- about the phenomena under consideration. The two principal disciplines of contemporary theoretical physics - quantum theory and the theory of relativity - fall basically into these respective categories. General Relativity and Matter represents a bold attempt by its author to formulate, in as transparent and complete a way as possible, a fundamental theory of matter rooted in the theory of relativity - where the latter is viewed as providing an explanatory level of understanding for probing the fundamental nature ofmatter indomainsranging all the way fromfermis and lessto light years and more. We hasten to add that this assertion is not meant to imply that the author pretends with his theory to encompass all ofphysics or even a tiny part of the complete objective understanding of our accessible universe. But he does adopt the philosophy that underlying all natural phenomena there is a common conceptualbasis,and then proceeds to investigate how far such a unified viewcan take us at its present stage of development.

Book Description
"UKRAY" - UNIFIED FIELD THEORY - - A New Unification Theory on Electromagnetic Gravitation- PREFACE “This study which aims to prove that all forces and laws of physics exist in a single unified structure at the Starting and Ending moment of the Universe analyzes all laws of physics within the framework of a unified structure from Newton Mechanics to Quantum Theory, Einstein Relativity to modern 11-dimensional Super string theory. The study may also be considered as a "MODERN ERA PRINCIPIA" since it was started to be written in about 300 years (early 2007) after the publication of the great study of Newton named "PRINCIPIA" (1703-1707) on the topic of gravity theories. The volume includes SEVEN CHAPTERS in the form of SEVEN different articles which follow each other and make clear the subject when they are read consecutively. In addition, FOUR additional chapters in the form of APPENDIXES in nature of FUNDAMENTALS OF MATHEMATICS were also included at the end of the volume for readers who have a less degree of technical knowledge about the topic... THIS THEORY, GETS THESE QUESTIONS INTO; - A CHANGE into Gravitational field and field equations, STATIC AND UNIVERSAL GRAVITATIONAL CONSTANTS, - THE DYNAMICS OF Gravitational field with Combining the Electromagnetics Theory. - THE VELOCITY OF LIGHT COULD BE EXCEEDED? THIS THEORY WAS PREPARED AS A CONSEQUENCE OF APPROXIMATELY 16 YEARS STUDY, - WHOLE "666" PAGE - INCLUDES ABOUT 100 THEOREMS, - AND 1000 ILLUSTRATED DRAWINGS, - ASSERTS THE NEW PHYSICS OF THE UNIVERSE. AND MUCH MORE... This oriented me to a series of researches to study and create this theory for years and then directed me to create a unified electromagnetic gravity theory composed of SEVEN ARTICLES in total I will submit here in order and step by step. Even though the theory includes a deductive mathematical approach, tensor calculation and geometric modellings, I will give solutions of Einstein-Maxwell Equations with a different mathematical 4x4 Pauli-Dirac Spinors and Tensor calculation construction in direction of closed extra dimension of the space (5 Dimension Effect) What Does the Theory Tell? {Short Abstract and Philosophy of the Theory} The THEORY summarizes the general and simple mathematical description of the universe in the form of general conclusion items and forecasts the followings; Basic Projections of the Theory? - NEW MODEL OF AN ATOM, - NEW MODEL OF THE UNIVERSE, - CHANGE IN GALILEO Inertia Principle, - A Fundamental Change in the Structure of MAXWELL's EQUATIONS, AN ADDITIONAL TERMS AND ADDITIONS, - A CHANGE IN POYNTING ENERGY THEORY, - A NEW ATOMIC MODEL, - A NEW UNIVERSE MODEL, - CHANGE IN GALILEO'S PRINCIPLE OF INERTIA, - A FUNDEMENTAL CHANGE AND AN ADDITIONAL TERM IN THE STRUCTURE IF MAXWELL EQUATIONS, - A CHANGE IN STATIC FIELD EQUATIONS OF THE GRAVITY FIELD AND IN THE UNIVERSAL GRAVITY CONSTANT. - CHANGE IN POYNTING ENERGY THEOREM, - HOW CAN THE VELOCITY OF LIGHT BE EXCEEDED?

Book Description
Despite the rapidly expanding ambit of physical research and the continual appearance of new branches of physics, the main thrust in its development was and is the attempt at a theoretical synthesis of the entire body of physical knowledge. The main triumphs in physical science were, as a rule, associ ated with the various phases of this synthesis. The most radical expression of this tendency is the program of construction of a unified physical theory. After Maxwellian electrodynamics had unified the phenomena of electricity, magnetism, and optics in a single theoretical scheme on the basis of the con cept of the electromagnetic field, the hope arose that the field concept would become the precise foundation of a new unified theory of the physical world. The limitations of an electromagnetic-field conception of physics, however, already had become clear in the first decade of the 20th century. The concept of a classical field was developed significantly in the general theory of relativity, which arose in the elaboration of a relativistic theory of gravitation. It was found that the gravitational field possesses, in addition to the properties inherent in the electromagnetic field, the important feature that it expresses the metric structure of the space-time continuum. This resulted in the following generalization of the program of a field synthesis of physics: The unified field representing gravitation and electromagnetism must also describe the geometry of space-time.
