An important component of DEMOS with POSITIVE IMPACT is the inclusion of visualizations for topics. We have tried to include different types of visualizations that are appropriate for the particular demo. In most cases we have there is an animation that introduces the demo and others which can be used by instructors as part of a lecture or presentation on the mathematical topic that is the focus of the demo. In this regard we have tried to develop animations that are easy to run in various browsers and on various hardware. The two formats we have used are animated GIFs and QUICKTIME movies. The GIFs can be run using a variety of viewing tools that usually come standard with the operating system. Some of the GIF viewing tools have a start-stop feature which is very convenient for classroom use. The QUICKTIME movies require a plugin, the QUICKTIME player, which is a free download. (Click here.) The QUICKTIME player comes with a built-in start-stop feature.
For some demo topics we have constructed a GALLERY of animations that provide a set of visualizations for the mathematical topic. Galleries are included as part of the following demos:
