Mathematics Demos
For students in mathematics, it is often very difficult to visualize abstract concepts. One of the most obvious examples is the analysis of three dimensional objects, or a 3D coordinate system. This small collection of mathematics demos illustrates some of these concepts by using multi-color animations. Items such as contours, Fourier transforms, and convolution, which cannot be effectively drawn on a chalkboard, are shown in great detail here. The site also demonstrates the dimensions of the sp

Self-Healing Minefield
The self-healing antitank minefield is an innovative system developed by the Defense Advanced Research Projects Agency (DARPA). It employs intelligent, mobile mines that can rearrange themselves to repair any breaches in the field. This forces the enemy to destroy a much greater percentage of the total mines, rather than simply clearing a narrow path. The project's Web site has considerable material on the mines' operation, including a very illustrative multimedia demonstration. There are also b
