Atom in a Box is an application that aids in visualizing the Hydrogenic atomic orbitals, a prime and otherwise unwieldy example of quantum mechanics. Unlike other tools in this category, this program raytraces through a three-dimensional cloud density...
This postcardware program efficiently simulates Fresnel diffraction by any two-dimensional aperture using an algorithm published in the Nov/Dec 1996 issue of _Computers In Physics_. It contains an interactive user-interface and a self-demo to aid in use...
Solar System Sim simulates N-body problems in three dimensions and visualizes the solution in a compelling display. The simulation uses an attractive force between bodies which varies by the distance between them raised to a power of your choosing. The...
A standalone Macintosh program to compute simultaneous and separate tests of regression slopes for test bias analysis.Requirements:OS 10.4 or...
Little calculator with key-equivalency system (you can link a key with any operator or number in the calculator). Very useful for laptop users !Requirements:Mac OS X 10.3.9 or...
This package brings a scripting addition ConvexPoly.osax and sample files to handle three dimensional convex polyhedra. Convex polyhedra are simple enough 3D objects so that vectorial rendering is possible. This is the motivation for this osax with which...
Snakey Math is an educational game combining arithmetic practice with classic arcade action for one to four players. Compete against other players and/or computer-controlled snakes to eat answers to problems. Many math options including various number...
Spokcalc Mac calculates spoke lengths for wire spoked wheels. Spokcalc includes a database of over 400 hubs and 550 rims. The Spokcalc database is also user-modifiable and -expandable so you can add more rims and hubs. Stelvio Bokforing Lon Ekonomi for...
This program calculates the coefficient of congruence for comparing factor solutions from different studies or different samples. It is typically used to determine the factorial invariance of solutions across samples or studies. "The congruence...
