Spacetime

The Simultaneity Spacetime Diagram model uses light-trajectories to show the effect of relative motion when observing (recording) events in special relativity. In the default scenario, an explosion (an event) at the center of a right-moving stick occurs at t=0 and the arrival of the explosion... Platforms: Mac

SpaceTime 3D Beta 9 is a curious browser that when loading webpages applies a three dimensional effect to show you it in 3D, and also giving each different page you visit a different look.As a browser it isn`t that useful (it`s a bit slow in searching) but at least it looks original.It also lets...

The Position Carpet package is a self-contained file for the teaching of the time evolution and visualization of energy eigenstates and their superpositions via quantum spacetime diagrams or quantum carpets. The file contains ready-to-run OSP programs and a set of curricular materials. The... Platforms: Mac

The Relativity on Rotated Graph Paper Model displays Minkowski spacetime diagrams on rotated graph paper. The worldlines of three inertial observers carrying horizontal light clocks and the resulting clock ticks are drawn. Each clock consists of two mirrors a constant distance d away from an...

Einstein's General Theory of Relativity demonstrates that a large mass can deform spacetime and bend the path of light. So, a very massive object, such as a cluster of galaxies can act as a gravitational lens. With this program, one can draw images to see the effect of gravitational Platforms: Windows

This is a function that simulate the Alamouti Space-Time scheme and plot a BER vs SNR graph. Platforms: Matlab

Split the signal S(SPACE,TIME) into its downward/upward space propagating and stationnary components via a 2D Fourier decomposition. S is a (SPACE,TIME) matrix. We eventually proceed to a space and/or time filtering. DT,DX are temporal and space step. PERIOD=[Tmin Tmax] and WAVELENGTH=[Xmin Xmax]... Platforms: Matlab

SOLVCON is a software framework for solving hyperbolic partial differential equations (PDEs). SOLVCON uses the space-time Conservation Element and Solution Element (CESE) method for time-accurate solutions. The goal of SOLVCON is to enable high-fidelity solutions for design iterations. SOLVCON is... Platforms: *nix
