Australasian Society for General Relativity and Gravitation Contents Membership information Newsletters Job vacancies Committee / contact information ... 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. The official name and constitution of the Society were adopted at the first General Meeting, which was held during the

82. Welcome To Foundation Physics This work is based on an elementary particle, the PParticle, and includes amongst other topics, discussions of relativity, origin of background radiation, nature of black holes and the nature of light. http://www.foundationphysics.com/

Foundation Physics: Preface: This work is based on an elementary particle, termed the 'P-Particle', which is first postulated to be the fundamental constituent of all matter present in the universe. The particle is defined by several axioms and can be regarded as being the quantum of matter. Just as energy is quantised, and energy and mass are interchangeable, then on this basis the idea of mass being quantised is first assumed and subsequently verified. It is subsequently shown that this particle can be identified with the neutrino. From this model, a large number of results are derived which potentially shed a new light on aspects of physics ranging from classical Newtonian mechanics and relativity to quantum mechanics and particle physics. Amongst the topics included are: Solutions to the Einstein-Friedmann equations A detailed evaluation of Schwartzchild and rotating black holes The expansion of the universe and its nature Dark matter The nature of light Background radiation and its origin Bijan Yavari In order to view the following you may need to install adobe acrobat reader which you may obtain from here Foundation Physics - Part 1 Foundation Physics - Part 2 Foundation Physics - Part 3

SPACETIME WRINKLES In 1905, Albert Einstein published his famous Special Theory of Relativity and overthrew commonsense assumptions about space and time. Relative to the observer, both are altered near the speed of light: distances appear to stretch; clocks tick more slowly. A decade and a year later, Einstein further challenged conventional wisdom by describing gravity as the warping of spacetime, not a force acting at a distance. Since then, Einstein's revolutionary insights have largely stood the test of time. One by one, his predictions have been borne out by experiment and observation. But it wasn't until much later that scientists accepted one of the most dramatic ramifications of Einstein's theory of gravitation: the existence of black holes from whose extreme gravity nothing, not even light, can escape. Major advances in computation are only now enabling scientists to simulate how black holes form, evolve, and interact. They're betting on powerful instruments now under construction to confirm that these exotic objects actually exist. You might like to take a two-minute video tour of this exhibit's contents.

Three earth-planes cut across each other at right angles, and human beings are living on each of them. It is impossible for the inhabitants of different worlds to walk or sit or stand on the same floor, because they have differing perceptions of what is horizontal and what is vertical. Yet they may well share the use of the same staircase. On the top staircase illustrated here, two people are moving side by side and in the same direction, and yet one of them is going downstairs and the other upstairs. Contact between them is out of the question because they live in different worlds and therefore can have no knowledge of each other's existence. Reprinted from the text of 'M.C.

91. SimScience - An Introduction To Simplicial Quantum Gravity Contains introductory material on quantum mechanics and relativity and outlines one method of combining the two theories. http://www.simscience.org/membranes/advanced/essay/quantum_grav1.html

An introduction to simplicial quantum gravity About three hundred years ago Isaac Newton wrote down rules describing the mechanics of moving objects. He also described gravity as a force that pulls massive objects together. Isaac Newton (1642-1727) We know today that Newtonian physics is really only an approximation that works well in almost every situation that we encounter in everyday life. We can use these rules to describe exactly how a baseball will travel when thrown. We know how to use Newton's laws so well that we can launch a rocket, and give it exactly the right amount of thrust so that it can coast to Jupiter, a planet only 90,000 miles across, but millions of miles distant from earth and orbiting at 30,000 miles per hour. This approximation is not good enough in some situations. If I want to describe the behavior of things on a very small scale, such as the motion of an electron around an atom, I cannot use the same Newtonian rules that I use to describe the motion of a baseball thrown across the infield. For really small-scale physics, I must use a new set of rules proposed in the early 1900's. These rules are called quantum mechanics There is another situation when Newtonian mechanics is not good enough. That is when we want to describe the motion of objects near very large masses like stars and whole galaxies. In these situations we must use another theory developed in the early 1900's, Albert Einstein's

97. The Sapir-Whorf Hypothesis 1999 overview of the history and development of the theories of linguistic determinism and linguistic relativity. By Rebecca Ash. http://www.angelfire.com/journal/worldtour99/sapirwhorf.html

The Sapir-Whorf Hypothesis From George Orwell's The Sapir-Whorf hypothesis theorizes that thoughts and behavior are determined (or are at least partially influenced) by language. If true in its strongest sense, the sinister possibility of a culture controlled by Newspeak or some other language is not just science fiction. Since its inception in the 1920s and 1930s, the Sapir-Whorf hypothesis has caused controversy and spawned research in a variety of disciplines including linguistics, psychology, philosophy, anthropology, and education. To this day it has not been completely disputed or defended, but has continued to intrigue researchers around the world. Edward Sapir and Benjamin Lee Whorf brought attention to the relationship between language, thought, and culture. Neither of them formally wrote the hypothesis nor supported it with empirical evidence, but through a thorough study of their writings about linguistics, researchers have found two main ideas. First, a theory of linguistic determinism that states that the language you speak determines the way that you will interpret the world around you. Second, a weaker theory of linguistic relativism that states that language merely influences your thoughts about the real world. Edward Sapir studied the research of Wilhelm von Humboldt. About one hundred years before Sapir published his linguistic theories, Humboldt wrote in

98. Concept Of Space And Time In Special Relativity Space and Time in Special relativity The modified. This java applet invitesyou to the world of space and time in special relativity. http://www.phy.ntnu.edu.tw/~hwang/relativity/relativity.html

Space and Time in Special Relativity The special theory of relativity is the result of two postulates: The laws of physics are the same in all inertial reference frames. Extention from the Newtonian principle of relativity: the laws of mechanics are the same for all observers in uniform motion. The speed of light in empty space is the same for all inertial frames. The speed of an object depends on the reference frame, however the speed of light in space is the same. From the above two postulates, our understanding of space and time has to be modified. This java applet invites you to the world of space and time in special relativity. There are two devices that utilize photons to measure time differences (some kind of clock). A mirror will reflect the photon when it reaches the top or bottom of the device. First, press Start button to begin the animation. Both devices are synchronized. Two Light pulses emitted from the ends (yellow rings) reach the center of the device at the same time. There is no relative motion between the two devices. Now, change the relative velocity from the selections (

99. To Understand Relativity TO UNDERSTAND relativity = You are travelling in a rocketat 200,000 km/sec, and you send, in your movement's direction, a projectile http://www.multimania.com/bvr/relativ.html

TO UNDERSTAND RELATIVITY You are travelling in a rocket at 200,000 km/sec, and you send, in your movement's direction, a projectile that, seen from the earth, propagates at 250,000 km/sec. Does it mean that, if you measure the speed of the projectile from the rocket, your measures will give 50,000 km/sec? It's not sure at all. To calculate the speed of the projectile, that is the distance covered by unit of time, you will have to use some instruments to measure the distance (a ruler) and the time (a clock). Let's take a simple clock, made of a light ray going on and back between two mirrors, distant of 1.5 meter. One second corresponds to 100,000,000 rebounds. You install this clock in the rocket so that the light ray propagates perpendicularly to the rocket's trajectory. For the ruler, it's a little more complicate, since the projectile moves outside the rocket. You find the following solution: before sending the projectile, you send a mirror (M) provided with a small motor before the rocket. You follow the progression of the mirror with the help of a light signal. When the signal will take 1/3 second to go to the mirror and come back, you will know that the mirror will be at 50,000 km. 1/6 of second before this moment, you send a signal starting the motor of the mirror in order to stop it (we suppose the motor reacts instantaneously). Then you control that the mirror remains stationary at this distance.

Archives Lit: Brace yourself, Mitchard’s latest headed our way By Heather Lee Schroeder March 2, 2001 Email this story to a friend Printer-friendly format Related information Booksense bestseller lists (A compilation from independent bookstores) It wasn’t there when I left work on Monday, but by Tuesday the advance reader’s copy of Jacquelyn Mitchard’s newest novel, "A Theory of Relativity" had arrived. It was wrapped inconspicuously enough that I didn’t suspect a thing. When I opened the brown mailer, I took one look and slid the book under a pile of papers on my desk. I knew that if anyone saw it, this book would get snatched away from me before I’d even had a chance to take a peek between its covers. In Wisconsin, a new Mitchard book has the cachet of, say, a new John Updike novel in New York. Later, I let my boss know it had arrived, and I even let him hold it. He read the back cover, clutched it close and feinted back and forth as if to hand it back to me, but he didn’t. My hand remained outstretched, and I fixed him with an eagle eye. He finally relinquished it.
