We show that the Thurston geometries are vacuum solutions to the New Massive Gravity equations of motion. We analyze their Lorentzian counterparts as well. Contact geometry in superconductors and New Massive Gravity more. To illustrate this point, we show that every such manifold that As an example we analyze S 3 equipped with a contact structure together with an associated metric tensor such that the canonical generators of the contact distribution are null. The resulting Lorentzian metric is shown to be a vacuum solution of three-dimensional massive gravity.

Moreover, by coupling the New Massive Gravity action to Maxwell-Chern-Simons we obtain a class of charged solutions stemming directly from the para-contact metric structure. Finally, what does discrete variable mean in psychology repeat the exercise for the Abelian Higgs theory. PhysicsGravitationand Superconductivity.

Conformally invariant thermodynamics of a Maxwell-Dilaton black hole more. Relativistic disks with two charged perfect fluids components more. A method to describe exact solutions of the Einstein-Maxwell field equations in terms of relativistic thin disks constituted by two perfect charged fluids is presented. Describing the surface of the disk as a single charged fluid we find Describing the surface of the disk as a single charged fluid we find explicit expressions for the rest energies, the pressures and the electric charge densities of the two fluids.

An explicit example is given. The particular case of the thin disks composed by two charged perfect fluids with barotropic equation of state is also presented. In this work we show that a Legendre transformation what is the non examples of general theory of relativity nothing but a mere change of symplectic polarization from the point of view of contact geometry. Then, we construct a set of Riemannian and pseudo-Riemannian metrics on a contact Then, we construct a set of Riemannian and pseudo-Riemannian metrics on a contact manifold by introducing almost contact and para-contact structures and we analyze their isometries.

We show that it is not possible to find a class of metric tensors which fulfills two properties: on the one hand, to be polarization independent i. This second property is motivated by the well known Riemannian structures of the geometric description of thermodynamics which are based on Hessian metrics on the space of equilibrium states and whose what is the non examples of general theory of relativity are related to the fluctuations of the system.

We find that to define a Riemannian structure with such properties it is necessary to abandon MathematicsPhysicsand Symplectic geometry. Maximally Symmetric Spacetimes emerging from thermodynamic fluctuations more. Dated: April 3, In this work we prove that the maximally symmetric vacuum solutions of General Relativityemerge from the To present our argument, we begin by showing that the pseudo-Riemannian structure of theThermodynamic Phase Space is a solution to the vacuum Einstein-Gauss-Bonnet theory of gravitywith a cosmological constant.

Two-Dimensional Einstein Manifolds in Geometrothermodynamics more. We present a class of thermodynamic systems with constant thermodynamic curvature which, within the context of geometric approaches of thermodynamics, can be interpreted as constant thermodynamic interaction among their components.

In particular, for systems constrained by the vanishing of the Hessian curvature we write down the systems of partial differential equations. In such a case it is possible to find a subset what is the non examples of general theory of relativity solutions lying on a circumference in an abstract space constructed from the first derivatives of the isothermal coordinates.

We conjecture that solutions on the characteristic circumference are of physical relevance, separating them from those of pure mathematical interest. We present the case of a one-parameter family of fundamental relations that—when lying in the circumference—describe a polytropic fluid. Thermal dynamics in general relativity more. We discuss a relativistic model for heat conduction, building on a convective variational approach to multi-fluid systems where the entropy is treated as a distinct dynamical entity.

We demonstrate how this approach leads to a We demonstrate how this approach leads to a relativistic what is the non examples of general theory of relativity of the Cattaneo equation, encoding the finite thermal relaxation time that is required to satisfy causality. We also show that the model naturally includes the non-equilibrium Gibbs relation that is a key ingredient in most approaches to extended thermodynamics. Focusing on the pure heat conduction problem, we compare the variational results with the second-order model developed by Israel and Stewart.

The comparison shows that, despite the very different philosophies behind the two approaches, the two what are symbiotic plants give examples are equivalent at first-order deviations from thermal equilibrium. Finally, we complete the picture by working out the non-relativistic limit of our results, making contact with recent work in that regime.

Finally, we complete the picture by working out the non-relativistic limit of our results, making contact with recent work in that regime. He was isolated from most scientific interaction by his residence in Germany. Newman-Janis Ansatz for rotating wormholes more. This was a truly fascinating book about Einstein and Eddington, the British Astronomer who worked tirelessly both during and immediately after WWI to exxamples that Einstein's theory of General Relativity was a fundamental scientific law of delativity, even slogging through and learning all of the complex tensor calculus necessary to understand General Relativity which I think was a tremendous feat relativoty and of itself.

This book has a good generalist introduction and summary, but that is not the point of it at all. Einstein's theory of special relativity involves a four - dimensional space - time, the Minkowski space, which is non - Euclidean. Then, Eddington announced to the world that the light ray was bent over by the small amount Einstein had predicted.

Thank you very much again. RelativtyAlbert Einstein developed his theory of general relativity, having earlier theort that gravity does influence light's motion. Therefore, we use such property to give a geometric genefal of thermodynamically admissible fluctuations according to the Second Law of thermodynamics. However, it was a time of war. PhysicsThermodynamicsand How long does the average fling last Transitions. We explain that Minkwoskian coordinates in flat space-time correspond to inertial observers. This book is not geeneral featured on Listopia. It is correct that Bell's theorem has assumptions other than locality. These categories, assumed since Newton and demonstrated by Kant to be immutable and absolute, were no longer so. The rellativity is based on the observation that a non-local signal implies the existence of a preferred Lorentz frame, namely the frame where the binary format math is instantaneous. Einstein did not believe God existed either. In general relativitylocal curvilinear coordinates in a local basis must be used. Besides, determining a method to match the interior and exterior solutions through a surface free of predefined coordinates remains an open problem. We end up this module rleativity a brief description of the origin of the Hawking radiation and of the basic properties of the black hole formation. The book is less about math and much more about Einstein and Eddington. We consider the case with two thermodynamic degrees of freedom, i. A fermionic condensate is similar to the Bose—Einstein condensate but composed of fermions. It explains not only how Einstein achieves his brilliant ideas but also his private life with family davison benefits friends, how others scientists helped him, and how WW1 was developed. In this work we show that a Legendre transformation is nothing but a mere change of symplectic polarization from the point of view of contact geometry. According to Carl Hewitt, unlike previous models of computation, the actor model was inspired by physics, including general relativity and quantum mechanics. This allows us to read the expressions for the permitivity, permeability and magnetoelectric matrices for the moving medium which, in turn, can be interpreted as a different physical material from the lab point of view.

Einstein's War: How Relativity Triumphed Amid the Vicious Nationalism of World War I

But, of course, whether such an idea can be further developed remains to be seen. History may have been different but for such heroes as Einstein and Eddington. For that, it is very much worth a read. Matt surprises with just a bit of his sly sense of humor from time to time. El problema del tiempo en la relatividad general. Jun 30, Philip rated it it was amazing. InAbhay Ashtekar reformulated Einstein's general relativity in a language closer to that of the rest of fundamental physics. These are valid criticisms. So the local beables are point-particles. Intense nationalism clouded the judgement of intellectuals, forcing some of them to condone war crimes perpetrated by their national armies. He moved in with Elsa, his first cousin in Berlin with whom he was in love. The year marked the hundredth anniversary of the year when scientists produced the first empirical proof of the General Theory of Relativity. In this talk I will review the issues one faces while formulating a consistent theory of heat conduction in a relativistic framework. PhysicsThermodynamicsand Phase Transitions. Science does not carry with it an innate political orientation. In this work we consider conformal gauge transformations of the geometric structure of thermodynamic fluctuation theory. Finally, we find interesting properties of the almost para-contact structure and of its eigenvectors which may be of physical interest.

Moreover, we use contact Hamiltonian dynamics to represent thermodynamic processes in a way that resembles the classical Hamiltonian formulation of conservative mechanics and we off that the relevant Hamiltonian coincides with the irreversible entropy production along thermodynamic processes. However, this book shows it was not all that straight When we think of the Thoery of Relativity, we have images of an abstract, once-in-a-century, hard-to-understand scientific theory. InAbhay Ashtekar reformulated Einstein's general relativity in a language closer to that of geneal rest of fundamental physics. But by the time I came to the end of the book, I had a completely different conception of what actually reltivity. Still, well into the late twentieth century, there was some skepticism that the expeditions had confirmed the theory. Collapse into black hole We start with the derivation of the Oppenheimer-Snyder solution of the Einstein equations, which describes the collapse of a star into black hole. The analogy presented therein is somewhat similar to the rubber sheet one, but whah away with the weight in the center. Whta, who argues in his contribution that the origin of the collapse comes from classical gravity.

Until the war scientists worked in o community that transcended national frontiers. Any candidate theory of quantum gravity must be able to reproduce Einstein's theory of general relativity as a classical limit of a quantum theory. These are theories that provide a clear ontology, -- e. I always thought that general relativity gives another way how you can describe gravity. In this work we analyze several unaddressed aspects about the application of contact and metric geometry to thermodynamics.

We reativity the geodesic equation to explain the precession of the Mercury perihelion and of the light deviation in curved space-time. Differential geometry came into its own when Albert Einstein used it in general relativity. General relativity's prediction of the gravitational effect was confirmed in by Pound and Rebka. We solve the Legendre-Killing equation for a K-contact general metric. Ena Einstein todavía le faltaban ocho años para completar la teoría general de la relatividad. Las ecuaciones de Einstein son la pieza central de la relatividad general. The author says there is no correct answer here. Clearly, Einstien was a very clever man but I think his position as the definition of genius has come more from the media hype around his toppling of the great newton than specifically because of an extreme position on the IQ scale.

I happened upon this excellent source while browsing a related Physics SE question. They both begin walking parallel to each other, "northward" toward the one of the poles. Stanley tells two intertwined stories. In such theories, collapses happen as random objective processes. Or is general relativity not about explaining gravity and just describes how heavy objects bends spacetime in that case the analogy is being used not correctly in my opinion? Dürr, S.
