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...

Worldlines visualizes special relativity, as particles near lightspeed trace paths in a 3D slice of 4D Minkowski spacetime. Scenes illustrate time dilation, the twin paradox, length contraction, and Bell's spaceship paradox. Platforms: Windows, Mac, Linux

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

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
