103. General Relativity And Cosmology An online notes from the University of British Columbia featuring simple explanations of cosmological phenomena. http://musr.physics.ubc.ca/~jess/p200/cosm/cosm.html

Next: Astronomy As Elementary Particle Physicists direct their attention ``down'' toward the indescribably tiny, so Cosmologists turn their gaze ``upward'' toward the unfathomably huge. Of course, these days both are increasingly likely to be incarnate in the same individual - I'll get to that later. As one who has never looked through a telescope larger than I could carry, I am certain to give short shrift to the magnificent observational science of astronomy , which provides cosmology (a theoretical discipline) with all its data. But a summary of the former without good colour plates of star fields and nebulae would be a terrible waste anyway, so I hope I have motivated the curious to go out and read a good Astronomy book on their own. Moreover, I am so ignorant of General Relativity and most of the fine points of Cosmology that I really have no business writing about either. Therefore I must content myself with a justification in terms of my ``unique point of view,'' whereby I excuse the following distortions. Astronomy Tricks of the Trade Parallax Spectroscopy ...

Analog models of General Relativity This is the USA mirror of the homepage for the workshop on "Analog models of General Relativity". The primary website is maintained in Rio de Janeiro, Brazil. Homepage in Portuguese Workshop location and funding Participants Talks ... Brazilian website Aim of the workshop: This workshop dealt with various "analog models" for GR. These analog models include acoustics in flowing fluids, quasi-particles in superfluids, flowing Bose-Einstein condensates, slow light in flowing fluids, nonlinear electrodynamics, the Scharnhorst effect, and more. The common theme in all these analog models is the presence of an effective Lorentzian metric that governs perturbative fluctuations and/or quasi-particles. This effective metric forces the fluctuations to exhibit many of the kinematic features of general relativity, though dynamic features [those specifically based on the Einstein-Hilbert action] typically do not carry over. It seems plausible that we might be able to construct analog horizons in the laboratory in the not too distant future. Such analog horizons are expected to exhibit Hawking radiation, but possibly without any analog of Bekenstein entropy. Analog models of GR are useful probes of Hawking radiation: Because the short-distance physics is explicitly known (atomic physics), the cutoff is physically understood-this helps clarify the role of trans-Planckian frequencies in GR, which in these condensed-matter GR analogs are replaced by "trans-Bohrian" physics.

106. Special And General Relativity - New Mathematical Formulations Presentation of new mathematical formulations for both the Special and general Theories of relativity. http://www.relativitydomains.com

SPECIAL AND GENERAL RELATIVITY - NEW MATHEMATICAL FORMULATIONS The purpose of this site is the presentation of a new simplified mathematical formulation of Albert Einstein's Special Theory of Relativity, and the introduction of a new theory of Gravity. The content is therefore of a technical nature, requiring a good knowledge of mathematics, physics and applied mechanics up to graduate level. Links to Papers etc RELATIVITY GRAVITY COSMOLOGY Links to other web sites of a related nature Links PDF versions of all papers PDF The current literature on these theories primarily works with such techniques as Riemannian Geometry and the Tensor Calculus etc., and while these are extremely powerful mathematical tools, they are also very complex. Therefore, when applied to Einstein's two most well known theories, they result in a formulation quite difficult to follow for even the most accomplished post graduate student. In the presentations here, nothing more complex than first and second order differential equations of functions of a complex variable are used to initially develop the above theories from first principles. This forms the basis from which additional papers are developed extending the technique into further relativistic, gravitational and cosmological matters. The latter includes the development of a mathematically rigorous new theory for the origin and existence of the Universe. Note - In some papers the mathematical nomenclature uses a special font to represent a certain parameter. Within the text this may not display correctly, being replaced by a standard font, (For those who wish to display this parameter correctly, the necessary font is here

110. General Relativity The cornerstone of general relativity is something known as the principle of general relativity explains the effects of gravity by divesting it of its http://www.herts.ac.uk/astro_ub/a13_ub.html

Astronomy GENERAL RELATIVITY Special relativity dealt with observers and systems that were in uniform constant motion to one another. Einstein wanted to extend this work to the general case, when a system is changing its velocity as well. This is the case when something is accelerating. By extending relativity to accelerating frames of reference, Einstein also formulated a new, and so far, the best theory of gravity. The cornerstone of general relativity is something known as the principle of equivalence . It states that the conditions present in a gravity well can be exactly reproduced by an accelerating frame of reference. Also, a frame of reference with a force acting upon it, say a force of gravity, can be counteracted by a correctly chosen and applied acceleration. Thus forces and accelerations are equivalent. So, if we can understand an accelerating space , up and down, left and right and in and out can be linked with our one dimension of time, forwards. These can be thought of as a four dimensional spacetime continuum . Anything which moves through the universe travels along straight lines within this continuum. The lines are called geodesics and although they are straight, the continuum they move through, is often curved. This curvature occurs when massive objects such as stars, planets and, on much larger scales, galaxies distort the spacetime continuum into

Bunn Physics Department, University of Richmond, Richmond, Virginia 23173, USA August 19, 2004 Also available in Postscript and PDF Abstract: This is a brief introduction to general relativity, designed for both students and teachers of the subject. While there are many excellent expositions of general relativity, few adequately explain the geometrical meaning of the basic equation of the theory: Einstein's equation. Here we give a simple formulation of this equation in terms of the motion of freely falling test particles. We also sketch some of the consequences of this formulation and explain how it is equivalent to the usual one in terms of tensors. Finally, we include an annotated bibliography of books, articles and websites suitable for the student of relativity.

Other links worldwide The Australasian Society for General Relativity and Gravitation (ASGRG) was formed at a meeting of mathematicians and physicists in Canberra in September 1994. The Society aims to bring together researchers who work in a wide range of areas within mathematical, theoretical and experimental gravitation: exact solutions of general relativity, mathematical relativity, numerical relativity, quantum gravity, cosmology, estimation of the gravitational wave signals produced by astronomical sources, and development of techniques and technology for detecting these signals with earth- and satellite-based antennae. It was decided to form the society to facilitate discussion of mutual problems of interest and to provide greater cooperation to solve the outstanding problems in the various fields. We see our role as providing a regional forum in Australia and New Zealand similar to the recently formed Topical Interest Group in Gravitation of the American Physical Society, and the international GRG society.
