Relativity Tutorial Galilean Relativity Relativity can be described using space-time diagrams . Contrary to popular opinion, Einstein did not invent relativity. Galileo preceded him. Aristotle had proposed that moving objects (on the Earth) had a natural tendency to slow down and stop. This is shown in the space-time diagram below. Note the curved worldline above. This shows a variable velocity, or an acceleration . Galileo objected to Aristotle's hypothesis, and asked what happened to an object moving on a moving ship. Now it is still moving in its final state. Galileo proposed that it is only relative velocities that matter. Thus a space-time diagram can be transformed by painting it on the side of a deck of cards, and then skewing the deck to one side but keeping the edges along a straight line: Straight worldlines (unaccelerated particles) remain straight in this process. Thus Newton's First Law is preserved, and non-accelerated worldlines are special. This Galilean transformation does not affect the time. Thus two observers moving with respect to each other can still agree on the time, and thus the distance between two objects, which is the difference in their positions measured at equal times, can be defined. This allowed Newton to describe an inverse square law for gravity. But Galilean transformations do not preserve velocity. Thus the statement "The speed limit is 70 mph" does not make sense but don't try this in court. According to relativity, this must be re-expressed as "The magnitude of the relative velocity between your car and the pavement must be less than 70 mph". Relative velocities are OK.

General Relativity Tutorial John Baez This is bunch of interconnected web pages that serve as an informal introduction to general relativity. The goal is to demystify general relativity and get across the key ideas without big complicated calculations. You can begin by reading a Short Course Outline Clicking on any of the underlined key concepts will then take you to the corresponding point in a more detailed Long Course Outline In the long course outline, clicking on any underlined key concept will take you to a still more detailed exposition of that concept. Alternatively, you can begin to read some of the adventures of Oz and the Wizard However, unless you are already familiar with general relativity, to understand these adventures you will need to look at the other material from time to time. All this material originated on sci.physics. Much of it is written by Oz and me, but there are also substantial contributions by Ted Bunn, Ed Green, Keith Ramsay, Bruce Scott, Bronis Vidugiris, and Michael Weiss. General relativity is usually written with lots of superscripts and subscripts. Mitchell Charity has kindly improved these web pages so that they look nice. However, not all web browsers can handle this.

General Relativity Simulation Contest Description of Contest The purpose of this Contest is to prove General Relativity. The Contest consist of the following task: Write one general purpose program (any programming language will do) which simulates the movement of n objects over a certain period of time. The simulation method used (algorithms), should be based on the Rules of General Relativity. The program should be able to simulate and demonstrate the following examples: Forward movement (perihelion shift) of the planet Mercury (43 arc sec angle) around the Sun. The bending of light around the Sun (1.75 sec). The movement of a binary star system. The stars should spiral together. A clock in a space ship around the Earth. Twin paradox (SR). i.e. at least two clocks should be included. The behaviour of black holes. The results of the simulation should match actual observations. For the rules of General Relativity see the following: General Relativity with John Baez For the most elaborate list of links for General Relativity see: Relativity on the World Wide Web by Chris Hillman , maintained by John Baez For a technical discussion about the problems with numerical simulations regarding General Relativity see: Numerical Relativity If you want more about celestial mechanics simulations informal newsletter

17. Chomsky UD Review by US political dissident Noam Chomsky of the United States' own appalling record on human rights not in the distant past, but in the last 50 years and continuing right up to this day. http://www.zmag.org/chomsky/articles/9708-UD-relativity.html

The United States and the "Challenge of Relativity" By Noam Chomsky This essay will appear in a collection assembled by Tony Evans, dealing with the 50th anniversary of the Universal Declaration of the Rights of Man. The adoption of the Universal Declaration of Human Rights on December 10, 1948 constituted a step forward in the slow progress towards protection of human rights. The overarching principle of the UD is universality. Its provisions have equal standing. There are no moral grounds for self-serving "relativism," which selects for convenience; still less for the particularly ugly form of relativism that converts the UD into a weapon to wield selectively against designated enemies. The 50th anniversary of the UD provides a welcome occasion for reflection on such matters, and for steps to advance the principles that have been endorsed, at least rhetorically, by the nations of the world. The chasm that separates words from actions requires no comment; the annual reports of the major human rights organizations provide more than ample testimony. And there is no shortage of impressive rhetoric. One would have to search far to find a place where leadership and intellectuals do not issue ringing endorsements of the principles and bitter condemnation of those who violate them notably excluding themselves and their associates and clients.

This assumption extends the principle of relativityto the case of uniformly accelerated motion of the reference frame. http://www-gap.dcs.st-and.ac.uk/~history/HistTopics/General_relativity.html

General relativity Mathematical Physics index History Topics Index General relativity is a theory of gravitation and to understand the background to the theory we have to look at how theories of gravitation developed. Aristotle 's notion of the motion of bodies impeded understanding of gravitation for a long time. He believed that force could only be applied by contact, force at a distance being impossible, and a constant force was required to maintain a body in uniform motion. Copernicus 's view of the solar system was important as it allowed sensible consideration of gravitation. Kepler 's laws of planetary motion and Galileo 's understanding of the motion and falling bodies set the scene for Newton 's theory of gravity which was presented in the Principia in 1687. Newton 's law of gravitation is expressed by F G M M d where F is the force between the bodies of masses M M and d is the distance between them. G is the universal gravitational constant. After receiving their definitive analytic form from Euler Newton 's axioms of motion were reworked by Lagrange Hamilton , and Jacobi into very powerful and general methods, which employed new analytic quantities, such as potential, related to force but remote from everyday experience.
