Many people think that mathematics is horribly difficult. In my opinion, part of the cause of this is that we do not always get to explore mathematical topics by playing around with them. So I mean to provide some software that will enable us to do just that.
For starters, I will provide some interactive geometry—that is, diagrams that you can interact with. For this to work, I have put little programs, called "applets," on some pages. If these do not seem to work, the page on Applet Problems may be helpful.
These links will go live as I finish the relevant Web pages.
I am developing some interactive software to visualize three-dimensional star polyhedra.
Magic squares are a perennial topic of recreational math. I have discovered an algebraic technique that can be used to create many magic squares, some with additional "magic" properties. The math here is easy, but unfamiliar to many people. I hope to make it more familiar, but still easy.
