These are some educational java applets I wrote to help visualize various concepts in math, physics, and engineering. You should be able to view them with any Java-capable browser.

Technology Problems of the Week (tPoWs) are freely accessible problem-solving challenges modeled on our Problems of the Week that take advantage of interactive mathematics tools such as Java applets, TI-Nspire™, The Geometer's Sketchpad®, Fathom™, or spreadsheets. Students are invited to use the link "Submit your answer" to share their solutions, and then "self-mentor" using specially designed hints, checks, and suggestions for extensions.

Great calculus website for teachers and students.

Terry Freedman sent this to me for a student struggling with calculus. What a great resource for kids tking calculus. I particularly love the calculus applets.

dynamic mathematics software for all levels of education that joins arithmetic, geometry, algebra and calculus. It offers multiple representations of objects in its graphics, algebra, and spreadsheet views that are all dynamically linked. While other interactive software (e.g. Cabri Geometry, Geometer's Sketchpad) focus on dynamic manipulations of geometrical objects, the idea behind GeoGebra is to connect geometric, algebraic, and numeric representations in an interactive way. You can do constructions with points, vectors, lines, conic sections as well as functions and change them dynamically afterwards. Furthermore, GeoGebra allows you to directly enter and manipulate equations and coordinates. Thus you can easily plot functions, work with sliders to investigate parameters, find symbolic derivatives, and use powerful commands like Root or Sequence.
