The Triumph of the Electromagnetic Theory
82,90 € *
ggf. zzgl. Versand

The unification of the fundamental forces of nature is an active field of research. Clearly, most of the scientists are guided by a cosmological motivation. The unified field force would be the single force at the beginning of the universe and would evolve into the four fundamental forces as the temperature of the early universe decreased. Until October 2013, no successful theory had been formulated and the unified force had remained a hypothetical force. Since then, an alternative unified field theory is available. The new theory provides a realistic cosmological model. It takes into account, for example, the existence of quasars and supernovae. It also provides new insights into various fields of science, including special relativity, general relativity, quantum mechanics, and elementary particle physics. This two-book series gives the last stroke of the brush at the theory of everything and should be especially useful to professionals and students in basic sciences, or anyone else who is interested in this long-searched for field theory, which allows one to settle once and for all the famous Bohr-Einstein debates as well as the debates about the origin and fate of the universe.

The Physics of the Black Holes
54,90 € *
ggf. zzgl. Versand

Quantum gravity is suppose to arise from a unification between relativity and quantum theory. We start this work with an overview over general relativity. The first chapter, as well the other two, is based on a series of lectures given by professor Leonard Susskind at Stanford University. Strings are very interesting objects which play a very important role in the quantum gravity. Open strings are known as photons, and closed strings as gravitons, both being quantum mechanical objects. This chapter describes in detail some properties of the open strings, and by analogy, on can derive as well the same properties for the closed strings case which play a central role in quantum gravity. In the the last chapter, and the most important one, we analyze the Black Holes and their quantum properties. They are described as strings. We end this work with the analogy between Black Hole horizon and de Sitter space horizon. The book is actually based on a series of lectures I gave at the Faculty of Mathematics and Computer Science, University of Bucharest, as a motivation for my PhD thesis 'Manifolds, submenifolds and their applications at the CERN Large Hadron Collider'.

Modified f(R) Theory of Einstein Gravity
59,00 € *
ggf. zzgl. Versand

Theory of f(R) gravity is a modification of Einstein's theory of General Relativity. It has received a great attention of the researchers due to its motivation coming from high-energy physics, cosmology and astrophysics. This theory has become a paradigm in bringing suitable cosmological models where cosmic acceleration can be achieved. In this work, two noteworthy issues of gravitational physics have been explored. One is the dark energy, thought to be responsible for the currently observed accelerated expansion of the universe while other is the gravitational collapse, a basic process driving evolution within galaxies, assembling giant molecular clouds and producing stars. Also, this book provide introduction to modern cosmology and basic knowledge about f(R) theory of gravity.

Classification of Gravitational Wave Triggers
21,99 € *
ggf. zzgl. Versand

Gravitational wave detection ceased to be a task limited to the LIGO-Virgo collabo- ration when data produced by the S5 and S6 runs were made public. With this in mind, the academic and scientific community set out to explore research options in this field through their own resources. As an attempt to become part of this open science movement, algorithms for classification of triggers are presented using data provided by the LVC collaboration. Different parameters are tested in order to enhance the dis- tinguishing between white noise burst and sine-Gaussian injections. The best of the implementations of the algorithms has a 99.8% efficiency for the data sampled. Being a work submitted in partial fulfillment for the degree of bachelor in engineering physics, this document also presents the author's acquired learning of gravitational wave science, starting from their motivation originated from General Relativity and finalizing in an analysis with real GW data.

Recently, the electromagnetic duality with fields and field sources has been studied and magnetic monopoles have been searched for. Elementary particles are then seen to have canonical properties and to be divided into the leptons and baryons as well as the visible and invisible particles. Next, non-composite elementary particles are fermions. The motivation of my research work is the search for an alternative unified field theory and a realistic cosmological model. The present work tackles this search. More developments of the electromagnetic theory are derived in this one. For non-accelerating particles, Maxwell's equations and the electromagnetic force, for example, are derived by means of the theory of special relativity. The electromagnetic field and potential produced by an accelerating electric monopole are derived by means of a new theory of general relativity. The gravitational force is revisited, the standard model of elementary particles is revised, and a cosmological model is proposed. This book should be especially useful to professionals and students in elementary particle physics and astrophysics, or anyone else who is interested in the existence of the universe.

The unification of the four fundamental forces is an active field of research. Up to now, no successful unified field theory has been formulated yet and the unified field force remains a hypothetical force. In spite of this situation, this goal continues to motivate research in theoretical physics. Scientists are clearly guided by a cosmological motivation. The unified field force would be the single force at the beginning of the universe and would evolve into the four fundamental forces as the temperature of the early universe decreased. A successful unified field theory must provide a realistic cosmological model. It should take into account the existence of quasars and other compact astronomical objects and be able to account for the mechanisms of such peculiar phenomena as the supernovae. An alternative unified field theory might exist and could start with new insights into the Lorentz transformations, the principle of special relativity, and the physical contents of these transformations. This book should be especially useful to professionals and students in elementary particle physics and astrophysics, or anyone else who is interested in the existence of the universe.

Static Universe
49,00 € *
ggf. zzgl. Versand

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A static universe or "Einstein universe" is one in which space is neither expanding nor contracting. Albert Einstein proposed such a model as his preferred cosmology in 1917. He added a positive cosmological constant to his equations of general relativity to counteract the attractive effects of gravity on ordinary matter, which would otherwise cause the universe to either collapse or expand forever. This motivation evaporated after the discovery by Edwin Hubble that the universe is in fact not static, but expanding, in particular, Hubble discovered a relationship between redshift and distance, which forms the basis for the modern expansion paradigm. According to Gamow this led Einstein to declare this cosmological model, and especially the introduction of the cosmological constant, his "biggest blunder".

Inertia and Gravitation
35,86 € *
ggf. zzgl. Versand

This book focuses on the phenomena of inertia and gravitation, one objective being to shed some new light on the basic laws of gravitational interaction and the fundamental nature and structures of spacetime. Chapter 1 is devoted to an extensive, partly new analysis of the law of inertia. The underlying mathematical and geometrical structure of Newtonian spacetime is presented from a four-dimensional point of view, and some historical difficulties and controversies - in particular the concepts of free particles and straight lines - are critically analyzed, while connections to projective geometry are also explored. The relativistic extensions of the law of gravitation and its intriguing consequences are studied in Chapter 2. This is achieved, following the works of Weyl, Ehlers, Pirani and Schild, by adopting a point of view of the combined conformal and projective structure of spacetime. Specifically, Mach's fundamental critique of Newton's concepts of 'absolute space' and 'absolute time' was a decisive motivation for Einstein's development of general relativity, and his equivalence principle provided a new perspective on inertia. In Chapter 3 the very special mathematical structure of Einstein's field equations is analyzed, and some of their remarkable physical predictions are presented. By analyzing different types of dragging phenomena, Chapter 4 reviews to what extent the equivalence principle is realized in general relativity - a question intimately connected to the 'new force' of gravitomagnetism, which was theoretically predicted by Einstein and Thirring but which was only recently experimentally confirmed and is thus of current interest.
