UNIT 56 THE SPECIAL THEORY OF RELATIVITY Written for students in the USC Self-Paced Astronomy Courses Learning Objectives and References are in the Study Guide. Sample Questions are on the web at http://spastro.physics.sc.edu/ ESSAY The Special Theory of Relativity by J. L. Safko A. Principle of Relativity Newton's theory of gravity, first studied in Unit 3, is intimately related to his concept of space and time. He considered space and time to be absolute concepts which existed independently of the material universe. Space was a stage in which the planets and stars existed. As time passed, the objects in the material universe evolved against the fixed background of space. Newton also formalized the concept of the inertial frame (or inertial coordinate system). A coordinate system (or coordinate frame) is a grid of rods and clocks at rest with respect to each other that spans a region of space. A simplified drawing of a coordinate system is shown in Fig. 56-1. Using this coordinate system we can describe events. Events are things that can be located at a particular place in space and that occur at a given time. The flashbulb firing on your camera would be an example of an event. The measurement of an event is determining the position and time of an event. We also term this measuring the coordinates of an event. An inertial frame (or an inertial coordinate frame) is a coordinate system in which Newton's first law holds. Newton's first law, as given in Unit 3, is that in the absence of outside forces any body moves with constant velocity. Any coordinate system moving with constant velocity with respect to an inertial system is also an inertial system. These inertial frames were assumed by Newton to be of infinite extent. They covered the entire universe. According to Newton, once you know any inertial frame, you know them all, since each differs from another by a constant velocity.

44. General Relativity In 1907, two years after proposing the special theory of relativity, Einstein was preparing a review of special relativity when he suddenly wondered how http://www-groups.dcs.st-and.ac.uk/~history/HistTopics/General_relativity.html

General relativity Mathematical Physics index History Topics Index Version for printing 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.

46. Relativistic Velocities Here is the formula for adding velocities in special relativity when motion occurs in a single direction. http://math.ucr.edu/home/baez/physics/Relativity/SR/velocity.html

[Physics FAQ] Updated by Terence Tao 1997. Original by Philip Gibbs 1996. How Do You Add Velocities in Special Relativity? Suppose an object A is moving with a velocity v relative to an object B and B is moving with a velocity u (in the same direction) relative to an object C . What is the velocity of A relative to C v u A B C w In non-relativistic mechanics the velocities are simply added and the answer is that A is moving with a velocity w = u+v relative to C . But in special relativity the velocities must be combined using the formula w = (u + v)/(1 + uv/c If u and v are both small compared to the speed of light c , then the answer is approximately the same as the non-relativistic theory. In the limit where u is equal to c (because C is a massless particle moving to the left at the speed of light), the sum gives c . This confirms that anything going at the speed of light does so in all reference frames. This change in the velocity addition formula is not due to making measurements without taking into account time it takes light to travel or the Doppler effect. It is what is observed after such effects have been accounted for and is an effect of special relativity which cannot be accounted for with Newtonian mechanics. The formula can also be applied to velocities in opposite directions by simply changing signs of velocity values or by rearranging the formula and solving for v . In other words, If

48. On The Electrodynamics Of Moving Bodies an ``absolutely stationary space provided with special properties, The following reflexions are based on the principle of relativity and on the http://www.fourmilab.ch/etexts/einstein/specrel/www/

ON THE ELECTRODYNAMICS OF MOVING BODIES By A. Einstein June 30, 1905 Examples of this sort, together with the unsuccessful attempts to discover any motion of the earth relatively to the ``light medium,'' suggest that the phenomena of electrodynamics as well as of mechanics possess no properties corresponding to the idea of absolute rest. They suggest rather that, as has already been shown to the first order of small quantities, the same laws of electrodynamics and optics will be valid for all frames of reference for which the equations of mechanics hold good. We will raise this conjecture (the purport of which will hereafter be called the ``Principle of Relativity'') to the status of a postulate, and also introduce another postulate, which is only apparently irreconcilable with the former, namely, that light is always propagated in empty space with a definite velocity c which is independent of the state of motion of the emitting body. These two postulates suffice for the attainment of a simple and consistent theory of the electrodynamics of moving bodies based on Maxwell's theory for stationary bodies. The introduction of a ``luminiferous ether'' will prove to be superfluous inasmuch as the view here to be developed will not require an ``absolutely stationary space'' provided with special properties, nor assign a velocity-vector to a point of the empty space in which electromagnetic processes take place. The theory to be developed is basedlike all electrodynamicson the kinematics of the rigid body, since the assertions of any such theory have to do with the relationships between rigid bodies (systems of co-ordinates), clocks, and electromagnetic processes. Insufficient consideration of this circumstance lies at the root of the difficulties which the electrodynamics of moving bodies at present encounters.

C-ship helps you understand Einstein's theory of Special Relativity intuitively through the medium of computer-synthesised images. To view the images in this document, you need a graphics-oriented Web browser. We'll be looking at lots of pictures on our journey. Sending large pictures across the Internet consumes precious network bandwidth and can take a long time. So, I'll show small "thumbnail" views of most pictures, with words "GIF" and "JPEG" beneath the image. When you click on the word, you'll see the full-size image. Most of the images are understandable from the thumbnail views. It's up to you which images you'd like to examine in more detail. If your browser supports in-line JPEG images, click on JPEG, otherwise use GIF. JPEG images look much better and take much less time to transmit to your computer, but not all Web browsers understand them.

Logically, however, this page comes first. The postulates of special relativity The theory of special relativity can be derived formally from a small number of postulates. The fundamental postulates of special relativity can be expressed in various ways; you may find different versions of them in different books. The first two postulates below are assertions about the structure of spacetime, while the last two postulates form the heart of special relativity. 1. The Geometry of Spacetime Statement: "Space and time form a 4-dimensional continuum". Watch this 4D hypercube rotate (46K GIF movie) The postulate that spacetime forms a 4-dimensional continuum is a generalization of the classical Galilean concept that space and time form separate 3 and 1 dimensional continua. The postulate of a 4-dimensional spacetime continuum is retained in general relativity. Physicists widely believe that this postulate must ultimately break down, that space and time are quantized over extremely small intervals of space and time, the Planck length (
