The General Principle Of Relativity In Its Philosophical And Historical Aspect (1920)

Relativity: The Special and the General Theory began as a short paper and was eventually published as a book written by Albert Einstein with the aim of giving:
. . . an exact insight into the theory of relativity to those readers who, from a general scientific and philosophical point of view, are interested in the theory, but who are not conversant with the mathematical apparatus of theoretical physics.
- from the Preface
It was first published in German in 1916 and later translated into English in 1920. It is divided into 3 parts, the first dealing with special relativity, the second dealing with general relativity and the third dealing with considerations on the universe as a whole. There have been many versions published since the original in 1916, the latest in December, 2011. The work has been labeled by whom?] unique in that it gives readers an insight into the thought processes of one of the greatest minds of the 20th century.

'Quantum mechanics is perhaps the most successful theory ever formulated. The only problem with it, argues Lee Smolin, is that it is wrong ... a fount of provocative ideas ... lucid, upbeat and, finally, optimistic' Graham Farmelo, Nature Human beings, says Lee Smolin, author of The Trouble With Physics, have always had a problem with the boundary between reality and fantasy, confusing our representations of the world with the world itself. Nowhere is this more evident than in quantum physics, which forms the basis for our understanding of everything from elementary particles to the behaviour of materials. While quantum mechanics is currently our best theory of nature at an atomic scale, it has many puzzling qualities - qualities that preclude realism and therefore give an incomplete description of nature. Rather than question this version of quantum mechanics, however, whole groups of physicists have embraced it as correct and rejected realism. Subscribing to a kind of magical thinking, they believe that what is real is far beyond the world we perceive: indeed, that the 'true' world is hidden from our perception. Back in the 1920s Einstein, both a realist and a physicist, believed that it was necessary to go beyond quantum mechanics to discover what was missing from a true theory of the atoms. This was Einstein's unfinished mission, and it is Lee Smolin's too. Not only will this new model of quantum physics form the basis of solutions to many of the outstanding problems of physics, but, crucially, it is a theory that is realist in nature. At a time when science is under attack, and with it the belief in a real world in which facts are either true or false, never has the importance of building science on the correct foundations been more urgent.

This book has its origin in a one-year course for non-science majors that Professor Firk taught at Yale throughout the decade of the 1970's. It is intended for the inquisitive reader who wishes to gain an understanding of the immortal work of Einstein, the greatest scientist since Newton. Special Relativity deals with measurements of space, time and motion in inertial (non-accelerating) frames of reference. A popular account of Einstein's Theory of General Relativity, a theory of space, time, and motion in the presence of gravity, is given. The contents include: 1. Understanding the physical universe 2. Describing everyday motion; relative motion, Newton's Principle of Relativity, problems with light, 3. Einstein's Theory of Special Relativity simultaneity and synchronizing clocks, length contraction and time dilation, examples of Einstein's world, 4. Newtonian and Einsteinian mass 5. Equivalence of energy and mass, E = mc2 6. Principle of Equivalence 7. Einsteinian gravity; gravity and the bending of light, gravity and the flow of time, and red shifts, blue shifts, and black holes.

This book develops an Effective Theory of Quantum Gravity based on the two pillars of physics - namely, General Theory of Relativity and Quantum Mechanics. It opens up a new direction of research in the search for a quantum theory of gravity, by first exactly quantizing the Newton-Cartan-Schrodinger theory of non-relativistic gravity, and then special relativizing the quantized theory by invoking Mach's Principle in the case of the universe and Schwarzschild radius in the case of massive stars and black holes. The main technique employed for the latter task is a variational technique using a trial local density.

The standard interpretation of Special Relativity is that of the "space-time block," where the past, present and future are laid out in a vast, frozen structure. The origins of the "block" rest in Langevin's 1911 announcement of the twin paradox, the validity of this paradox also invariably being included as part of this standard view. The view is ubiquitous, is described repeatedly, and is completely misguided. This book explores the fundamental contradictions in this interpretation, its inconsistencies in the assignment of ontological status to time dilation versus the opposite for space contraction, its failure to properly factor the reciprocity of systems, the ultimate non-ontological status of the "block" and thus the non-status of relativity as a theory of time. In this, the work explores the problems for a theory of consciousness and perception inherent in the "block," the extensions of certain of the inconsistencies into the foundations of the General Theory, and the origins of relativity in the classic metaphysic of space and time - now outmoded. In contrast to the classic structure, the temporal metaphysic of Bergson is described with its indivisible or non-differentiable flow of time, where "objects" are simply transferences of state within the global motion of the universal field. In this framework, we see Bergson's remarkable model of perception with its natural marriage to that of the great perception theorist, J. J. Gibson. It is a model which generates a testable contradiction to the standard interpretation of relativity, and it is a model of conscious perception that relies on the reality of the simultaneity of flows of events - a fundamental feature of the fabric of time that relativity and the relativization of simultaneity cannot incorporate. This little book, it should be noted, for those who have read Time and Memory: A Primer on the Scientific Mysticism of Consciousness, is a modified version of a chapter or so in this earlier work.

The author reviews "Physical Geometry," a unified theory which proposes a solution to existing difficulties in Physics in line with Einstein's ideas. The fundamental problems in Physics are the following: 1-The Standard Model of Particle Physics, based on the electromagnetic, weak and strong nuclear interactions, appears incomplete and requires a complicated structure in terms of a very large number of empirical parameters. 2-Superstring Theory represents particles by strings or n-surfaces in spaces with high number of dimensions and has not produced verifiable experimental results. These models are not clearly related to a fundamental underlying theoretical physical interaction. 3-On the other hand, Gravitation and Electrodynamics are faced with serious theoretical challenges, particularly in Cosmic Physics due to the possible existence of dark matter and energy. The book offers new perspectives and concepts which the author hopes will be useful to physicists working in particle physics, cosmology and related lines. The Physical Geometry determines many new geometric numerical values for masses, binding energies, quantum eigenvalues and other physical constants which are not calculable from other known physical models. These bare numbers arise essentially from the concept of energy and a generalized nonlinear electrodynamics which determines a unified global field theory. Small perturbation corrections calculated using Quantum Field Theory should be applied to the resultant bare numbers. Within higher order corrections and experimental errors there appears to be no physical experimental evidence contradicting these results. The theory gives new surprising fundamental relations between the different forms of energy. In particular, it appears that nuclear energy is a strong nonlinear magnetic energy. These results substantiate a fundamental critique of present particle models and indicate the need of a research thrust along a new direction.

Throughout the decade of the 1990's, Professor Firk taught a one-year course of a specialized nature to students who entered Yale College with excellent preparation in Mathematics and the Physical Sciences, and who expressed an interest in Physics or a closely related field. The students were required to take the highest level of introductory Mathematics in parallel with the course. The book covers topics taught in the first semester; they include: 1. MATHEMATICAL PRELIMINARIES 2. KINEMATICS: THE GEOMETRY OF MOTION 3. CLASSICAL AND SPECIAL RELATIVITY 4. NEWTONIAN DYNAMICS 5. INVARIANCE PRINCIPLES AND CONSERVATION LAWS 6. EINSTEINIAN DYNAMICS

Relativity Revealed: A Concrete Approach You Can Understand presents Einstein's special theory of relativity in clear and simple language. This book is intended for high school students who may have an interest in science, or for adults who simply want to know what relativity is all about. The material in the book was twice presented by the author, Prof. Ray C. Jones, in a series of popular public lectures at Southwestern Oklahoma State University. Special relativity concerns the differences in physical quantities, such as time intervals, lengths and masses, that occur when measured by observers who are in constant speed motion relative to each other or to the objects being measured. Although relativity begins with simple statements about the speed of light and the nature of clocks, we soon find that it changes our perceptions of space and time and leads to an understanding of nuclear fission and fusion processes and the radiation of energy from the sun. This book, by an exceptional teacher, is a very good place to begin to learn of these things. In this book, Prof. Jones develops the major ideas of relativity from simple postulates about observations of the speed of light. The basic ideas are presented in simple language, but are then extended into a consistent logical framework with the aid of some minimal high school level mathematics. (The details of mathematical developments are presented in Appendices that will help to sharpen reader's skills.)

While layman may enjoy many parts of this book there are mathematical parts that may be challenging. This book describes a theory of the multiverse - an infinite expanse of space in which island universes are scattered including our universe. It develops the concept of universe particles and their interactions that lead to colliding universes, the creation of universe - anti universe pairs, and other dynamical phenomena: Tachyonic universes, left and right handed universes and so on. By making the multiverse a complex 16-dimensional space the author is able to show many newly found cosmological phenomena (by the Planck observatory and NASA's WMAP laboratory) can be understood: the origin of the cosmological constant, the origin of left and right handed universes (Our universe appears to favor left-handedness.), deviations from uniform expansion of our universe, spatial asymmetries of our universe, our lopsided universe, and an understanding of the origin for the newly found Web of Galaxies (that links all the groups of galaxies) in our universe. In addition the author develops a 16-dimensional baryonic gauge field, a universe particle quantum field theory representing expanding/contracting universes, an extension of the Wheeler-DeWitt equation to universes residing in a flat 16-dimensional multiverse called the Flatverse, features of the sister universe that are the source of inertial reference frames ..., and evidence for a wormhole connecting our universe and its sister universe. A new view of a new, larger reality.

A remarkable concept known as "entanglement" in quantum physics requires an incredibly bizarre link between subatomic particles. When one such particle is observed, quantum entanglement demands the rest of them to be affected instantaneously, even if they are universes apart. Einstein called this "spooky actions at a distance," and argued that such bizarre predictions of quantum theory show that it is an incomplete theory of nature. In 1964, however, John Bell proposed a theorem which seemed to prove that such spooky actions at a distance are inevitable for any physical theory, not just quantum theory. Since then many experiments have confirmed these long-distance correlations. But now, in this groundbreaking collection of papers, the author exposes a fatal flaw in the logic and mathematics of Bell's theorem, thus undermining its main conclusion, and proves that---as suspected by Einstein all along---there are no spooky actions at a distance in nature. The observed long-distance correlations among subatomic particles are dictated by a garden-variety "common cause," encoded within the topological structure of our ordinary physical space itself.

This is a physics based book on the subject of warp drive, hyperdrive, and wormhole type drives for the purpose of space craft propulsion.

Deep within galaxies like the Milky Way, astronomers have found a fascinating legacy of Einstein's general theory of relativity: supermassive black holes. Connected to the evolution of the galaxies that contain these black holes, galactic nuclei are the sites of uniquely energetic events, including quasars, stellar tidal disruptions, and the generation of gravitational waves. This textbook is the first comprehensive introduction to dynamical processes occurring in the vicinity of supermassive black holes in their galactic environment. Filling a critical gap, it is an authoritative resource for astrophysics and physics graduate students, and researchers focusing on galactic nuclei, the astrophysics of massive black holes, galactic dynamics, and gravitational wave detection. It is an ideal text for an advanced graduate-level course on galactic nuclei and as supplementary reading in graduate-level courses on high-energy astrophysics and galactic dynamics.

David Merritt summarizes the theoretical work of the last three decades on the evolution of galactic nuclei, the formation of massive black holes, and the interaction between black holes and stars. He explores in depth such important topics as observations of galactic nuclei, dynamical models, weighing black holes, motion near supermassive black holes, evolution of nuclei due to gravitational encounters, loss cone theory, and binary supermassive black holes. Self-contained and up-to-date, the textbook includes a summary of the current literature and previously unpublished work by the author.

For researchers working on active galactic nuclei, galaxy evolution, and the generation of gravitational waves, this book will be an essential resource.
