Principle of general covariance : The laws of physics must take the same form in all coordinate systems. Inertial motion is geodesic motion : The world lines of particles unaffected by forces (i.e. inertial motion) are timelike or null geodesic of spacetime. (This means the tangent vector is either negative or zero.) Local Lorentz invariance : The rules of special relativity apply locally for all inertial observers. Spacetime curvature : As described by Einstein's field equations, the curvature of spacetime in response to mass, energy, and momentum results in gravitational influences being viewed as a form of inertial motion.

85. Relativity Or Ether Theory With A New Propagation Of Light? A new analysis of the Michelson Experiment. http://www.norbertfeist.de/english.htm

Ether Theory or Relativity Theory? This website was created in June 2001. It has dealt from ellipsoidal wave propagation in an luminiferous ether. The hypothesis in agreement with H. Varcollier and L. Gooris was: The one way speed of light is dependent on the system speed v and on the emission angle in relation to the direction of motion The two way speed of light is the harmonious average value from equ. (1) for toward and away. At constant system speed v it has the equal amount for any emission angle and explains as far as the figures go the " zero result " of the Michelson - Morley experiment, comparable the assumption of a Lorentz contraction. Conclusions after 5 years internet presence: There was not an indication to the existence of ellipsoidal wave fronts (with the exception of Fresnel’s Ellipsoid in anisotropic materials), and there was not a professional repetition of my ultrasonic experiment. That’s still my conviction: There is a luminiferous ether and an exact identical Michelson-Morley experiment with sound in air must have the same result.

Relativity visualized Space Time Travel Next Prev Home site map contact Deutsch English Overview News FAQ Visualization of the theory of relativity. Online papers, images, movies and paper models by the physics education group of Ute Kraus This is an English version of the German site www.tempolimit-lichtgeschwindigkeit.de Relativity visualized The theory of relativity holds a certain fascination for many people. At the same time it is often regarded as very abstract and difficult to understand. Part of the difficulties in understanding relativity are due to the fact that relativistic effects contradict everyday experience. Motion, for example, is a familiar process and everybody "knows from experience" that it entails neither time dilation nor length contraction. A flight with half the speed of light could correct this misjudgement but is not on offer. A possible alternative are simulations. Images, films and virtual reality let us in a sense experience relativistic flights, gravitational collapse, compact objects and other extreme conditions.

87. Ricci: A Mathematica Package For Doing Tensor Calculations In Differential Geome A Mathematica package for doing tensor calculations in differential geometry and general relativity. http://www.math.washington.edu/~lee/Ricci/

Ricci A Mathematica package for doing tensor calculations in differential geometry Version 1.52 Last Updated August 28, 2006 Ricci is a Mathematica package for doing symbolic tensor computations that arise in differential geometry. It has the following features and capabilities: Manipulation of tensor expressions with and without indices Implicit use of the Einstein summation convention Correct manipulation of dummy indices Display of results in mathematical notation, with upper and lower indices Automatic calculation of covariant derivatives Automatic application of tensor symmetries Riemannian metrics and curvatures Differential forms Any number of vector bundles with user-defined characteristics Names of indices indicate which bundles they refer to Complex bundles and tensors Conjugation indicated by barred indices Connections with and without torsion Limitations: Ricci currently does not support computation of explicit values for tensor components in coordinates, or derivatives of tensors depending on parameters (as in geometric evolution equations or calculus of variations), although support for these is planned for a future release. Ricci also has no explicit support for general relativity, or for other mathematical physics or engineering applications, and none is planned. If you are interested in such support, I recommend that you consider the commercial package MathTensor, which is far more extensive than Ricci, and provides all these capabilities and more. MathTensor is available from

The Open Database Project succeeded in its aim of producing a "Proof of Concept" prototype Raquel Database System for public distribution, thanks to funding from "NStar". An Open Source project has now begun to evolve the prototype into a commercial product, and its website is here The home page of the original version of this website consisted of the following Mission Statement :- Welcome to the web site of the Open Database Project... The mission statement of the Open Database Project is as follows: To develop: A philosophy for a pure relational database model including object classes as data types orthogonal to relations An open architecture satisfying the philosophy A design for the architecture An implementation of the design To exploit the developments above through activities such as: Providing comprehensive view updating Providing sequences and bags as specialised types of relation Providing a visual interface for the architecture To make the code available as open source software To publish documents through the Internet and other means (Ratified by the project group in October 2002)

91. Tcl Relational Algebra Library A C-based extension of the TCL language implementing relational algebra. http://tclral.sourceforge.net/

Tcl Relational Algebra Library What is TclRal? TclRAL is a "C" based extention of the TCL language that is an implementation of the Relational Algebra. From a programmers point of view, the library is a Tcl package that introduces two new native data types and a set of commands that operate on them. The new data types are: Tuple Relation The library also contains three primary commands each of which is an ensemble of sub commands that are the operations available on the Tuple and Relation type. Other commands are provided to pretty print relation values and load/store sets of relation variables. tuple - operations on the tuple data type relvar - operations on variables that contain relations relation - operations on the relation data type relformat - generate a human readable tabular layout of a relation serialize - operations to load/store relation variable data What is Relational Algebra? Relational algebra is the application of formal mathematical concepts to managing data. It is most often discussed in terms of the Relational Model of Data and in that context it is often associated with Database Management Systems (DBMS). However, relations are logical entities and do not depend upon any particular DBMS for an implementation. TclRal is patterned after the relational algebra described by Date (Date, C.J., An Introduction to Database Systems , 8th ed, Pearson Education, 2004, ISBN 0-321-19784-4, chap. 7).
