Download or read book The Relativity of the Observer and the Gravity written by Karl-Herbert Darmer and published by BoD – Books on Demand. This book was released on 2022-04-21 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book describes in a very unconventional way the role of man as an observer in the universe that surrounds us. Many physical phenomena are described from an unfamiliar point of view. These include wave-particle duality of light, the speed of light, why are space and time relative, what does reality mean, what are reference systems, what do the Lorentz transformations link, without necessarily having to deal with mathematics. The book should be of interest to anyone who considers himself an observer. It doesn't matter what he wants to watch. It is about the principles that arise when observing. What can generally be regarded as secured. Unfortunately, that's not much, because in order to draw conclusions from what has been secured, you have to make assumptions. These do not have to be correct and results that are logically incompatible with these assumptions are excluded from the outset by these assumptions. If one is willing to break away from some of these assumptions, possible solutions could arise for puzzling observations in the sky.
Download or read book Gravity Black Holes and the Very Early Universe written by Tai L. Chow and published by Springer Science & Business Media. This book was released on 2007-10-24 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here it is, in a nutshell: the history of one genius’s most crucial work – discoveries that were to change the face of modern physics. In the early 1900s, Albert Einstein formulated two theories that would forever change the landscape of physics: the Special Theory of Relativity and the General Theory of Relativity. Respected American academic Professor Tai Chow tells us the story of these discoveries. He details the basic ideas of Einstein, including his law of gravitation. Deftly employing his inimitable writing style, he goes on to explain the physics behind black holes, weaving into his account an explanation of the structure of the universe and the science of cosmology.
Download or read book Gravitation and Relativity written by M. G. Bowler and published by Elsevier. This book was released on 2016-06-06 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: International Series in Natural Philosophy, Volume 86: Gravitation and Relativity provides information pertinent to the fundamental aspects of the theories of gravitation. This book applies the elementary tools of special relativity to the problem of generalizing Newton's theory of gravitation. Organized into 10 chapters, this volume begins with an overview of the principle of relativity, which asserts theta there is no meaningful way of defining absolute velocity. This text then presents a discussion of the Eötvös–Dicke experiments that established the identity of inertial and gravitational mass. Other chapters consider the equations of electrodynamics derived by starting from the equations of electrostatics. This book discusses as well gravitational redshift, deflection of light, and radar echo delay. The final chapter attempts to establish the connection with general relativity and discusses how black holes may manifest themselves to the astronomer. This book is a valuable resource for physicists and undergraduate students in physics.
Download or read book Space Time and Gravitation an Outline of the General Relativity Theory written by Arthur Eddington and published by . This book was released on 2013-03-26 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: By his theory of relativity Albert Einstein has provoked a revolution of thought in physical science.The achievement consists essentially in this: Einstein has succeeded in separating far more completely than hitherto the share of the observer and the share of external nature in the things we see happen. The perception of an object by an observer depends on his own situation and circumstances; for example, distance will make it appear smaller and dimmer. We make allowance for this almost unconsciously in interpreting what we see. But it now appears that the allowance made for the motion of the observer has hitherto been too crude a fact overlooked because in practice all observers share nearly the same motion, that of the earth. Physical space and time are found to be closely bound up with this motion of the observer; and only an amorphous combination of the two is left inherent in the external world. When space and time are relegated to their proper source the observer the world of nature which remains appears strangely unfamiliar; but it is in reality simplified, and the underlying unity of the principal phenomena is now clearly revealed. The deductions from this new outlook have, with one doubtful exception, been confirmed when tested by experiment.It is my aim to give an account of this work without introducing anything very technical in the way of mathematics, physics, or philosophy. The new view of space and time, so opposed to our habits of thought, must in any case demand unusual mental exercise. The results appear strange; and the incongruity is not without a humorous side. For the first nine chapters the task is one of interpreting a clear-cut theory, accepted in all its essentials by a large and growing school of physicists although perhaps not everyone would accept the author's views of its meaning.Chapters x and xi deal with very recent advances, with regard to which opinion is more fluid. As for the last chapter, containing the author's speculations on the meaning of nature, since it touches on the rudiments of a philosophical system, it is perhaps too sanguine to hope that it can ever be other than controversial.A non-mathematical presentation has necessary limitations; and the reader who wishes to learn how certain exact results follow from Einstein's, or even Newton's, law of gravitation is bound to seek the reasons in a mathematical treatise. But this limitation of range is perhaps less serious than the limitation of intrinsic truth. There is a relativity of truth, as there is a relativity of space. "For is and is-not though with Rule and Line and up-and-down without, I could define."Alas! It is not so simple. We abstract from the phenomena that which is peculiar to the position and motion of the observer; but can we abstract that which is peculiar to the limited imagination of the human brain? We think we can, but only in the symbolism of mathematics. As the language of a poet rings with a truth that eludes the clumsy explanations of his commentators, so the geometry of relativity in its perfect harmony expresses a truth of form and type in nature, which my bowdlerized version misses.But the mind is not content to leave scientific Truth in a dry husk of mathematical symbols, and demands that it shall be alloyed with familiar images. The mathematician, who handles x so lightly, may fairly be asked to state, not indeed the inscrutable meaning of x in nature, but the meaning which x conveys to him. Although primarily designed for readers without technical knowledge of the subject, it is hoped that the book may also appeal to those who have gone into the subject more deeply. A few notes have been added in the Appendix mainly to bridge the gap between this and more mathematical treatises, and to indicate the points of contact between the argument in the text and the parallel analytical investigation.

Download or read book Introduction to Einstein s Theory of Relativity written by Øyvind Grøn and published by Springer Nature. This book was released on 2020-05-27 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: The revised and updated 2nd edition of this established textbook provides a self-contained introduction to the general theory of relativity, describing not only the physical principles and applications of the theory, but also the mathematics needed, in particular the calculus of differential forms. Updated throughout, the book contains more detailed explanations and extended discussions of several conceptual points, and strengthened mathematical deductions where required. It includes examples of work conducted in the ten years since the first edition of the book was published, for example the pedagogically helpful concept of a "river of space" and a more detailed discussion of how far the principle of relativity is contained in the general theory of relativity. Also presented is a discussion of the concept of the 'gravitational field' in Einstein's theory, and some new material concerning the 'twin paradox' in the theory of relativity. Finally, the book contains a new section about gravitational waves, exploring the dramatic progress in this field following the LIGO observations. Based on a long-established masters course, the book serves advanced undergraduate and graduate level students, and also provides a useful reference for researchers.

Download or read book Gravity s Time written by C. S. Unnikrishnan and published by CRC Press. This book was released on 2022-04-28 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is unique and exceptional in dealing with the notion of physical time rigorously, both logically and empirically. The central theme is the intimate relation between physical time and cosmic gravity. It establishes and explains, in an accessible manner, the one crucial physical fact that has been missed in the development of modern physics—that the enormous gravity of the matter and energy in the Universe is the controller and cause of the relativistic time. The material in the book is accurate and free of the ambiguities in the discussion of time and its modifications (dilation), synchronization of clocks, and simultaneity. The contents go beyond the current theories of relativity that fail to incorporate the cosmic gravity in their structure. The discussion of clocks in satellite navigational systems (like the GPS) is the most complete and accurate. The book offers several new insights, and it is the only available treatise on the complete physical truth about time. The contents are addressed to a wide range of readers, from general readers and students to experienced researchers, and will also appeal well to philosophers and historians of physics. This book has the enabling quality to deal with difficult questions about physical time, with unprecedented clarity and without paradoxes.

Download or read book Unification of Electromagnetism and Gravity written by Selwyn E Wright and published by Trafford Publishing. This book was released on 2014-02-27 with total page 258 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.
