3D particle tracer designed to simulate the movement of charged particles in the presence of electric and magnetic fields. The code is widely used for accelerator, beamline and FEL design.

The program displays graphically the emission spectra of elements from 1 to 99, in the visible, infrared, and ultraviolet ranges. Freeware.

Library containing over 1800 refereed programs in computational physics and physical chemistry which are described in the journal Computer Physics Communications published by Elsevier Science.

Calculates the phonon dispersion relations and phonon density of states for any crystal from force constants, or from Hellmann-Feynman forces supplied by an ab initio program.

Catalog of resources in engineering, physics, field physics, and astrophysics. Includes digital picture processing, medical image processing and stellar structure software.

Links to reviewed physics software and programs.

Special relativity simulator, including doppler shifting, lorentz transforms, optical aberration, and the headlight effect.

It's a 3D realtime interactive gravity simulator, designed to simulate thousands of bodies (e.g stars, asteroids etc.).

Supplies databases of XPS spectra, spectra handbooks on CD-ROM, and software for processing AES or XPS data.

FeynDraw Windows program is used to quickly draw, scale, print, and save as images, Feynman, qed, qcd, twistor, string, or other particle physics diagrams and can be downloaded free for trial use.
