4434Constructing Physics Understanding (CPU Project)
http://www.merlot.org/merlot/viewMaterial.htm?id=266439
Aimed at creating laboratory and computer-based materials to support a learning environment where students take primary responsibility for developing valid and robust classrooms, and also prospective or practicing teachers through workshops and university courses. Includes software for the MAC and PC.Fourier Transform
http://www.merlot.org/merlot/viewMaterial.htm?id=91098
This is a simple demonstration of the Fourier transform (diffraction pattern) of a point set. This program produces black/white or color PostScript output. The source code is provided with the package. This DEMO program is similar to the one that Marjorie Senechal shows in her book Quasicrystals and Geometry. It is possible to give scale factors for the intensity and for the input data to produce different graphics output. You may also choose between kinematical or dynamical intensity distribution. For input you only need an input file with the x- and y-coordinates of a point set.Table of Fundamental Physics Constants
