Interactive Mathematics and Puzzles

The purpose of this site is set out in the Manifesto. You can navigate through the site with the help of red/yellow buttons at the top of every page, the left navigational bar, or a few buttons to the critical pages placed at the bottom of the site.

The site is a collection of K16 topics drawn from arithmetic,algebra,geometry,probability, logic, social sciences, math fallacies, visual illusions and a good deal of miscellany. More than 550 interactive Java illustrations help enliven some topics, while making others more comprehensible. One can get a good introduction at the contents page.

I am convinced that mathematics should be studied because of its intrinsic beauty, not because of its utility.
