Educational and Visualisation Programs developed in Bergen


Most of the programs below have a long history. They are codes often originally written in basic for the Atari-ST, then translated to FORTRAN or C and moved to PC (MS-DOS) or workstations. Some were also originally developed for Macintosh.
In most cases, the programs are tools for a teacher or an instructor. They are not written as "Applications", rather as viewers or tools.

In general, these codes are a useful resource which can be further used in developement of applications.

Bitmap viewers

MS-DOS ( Turbo C BGI)
Sun Sparcstation

Trajectory Viewers

Sun Sparcstation (several versions) C, pixrect library, SunView
X11 - Motif
MS-DOS graphics

Golden Rule Simulator

FORTRAN program using CGI graphics (has been rewritten, CGI obsolete) Sun Sparcstation
C-program using RISGS on MS-DOS, MacOS, X-windows (Xlib)
This program solves the Schršdinger equation for a model problem, related to Fermi's Golden Rule

Interacting Harmonic Oscillators.

FORTRAN programs produce data-files (E.Svinsaas Thesis) ( X11-Motif graphics, MS-DOS graphics ; Both viewing programs show the same data files) This program displays results of calculations, animates line Drawings

Schršdingers Toy

Macintosh Interactive program,
Schroedinger Equation,
Bound States,
Resonances This program is an Essay on Interactive Computational Physics; Numerics, Graphics, Teaching Philosophy


MS-DOS ( Turbo C BGI);
