• Mathematical Gems This page contains a number of mathematical problems, concepts, and arguments that I find intriguing. A number of them roused or reinforced my interest in mathematics when I was a high school student.
• Fourteen Proofs of Euler's Formula: V-E+F=2
• Polyhedra
• Geometry in Action This page collects various areas in which ideas from discrete and computational geometry (meaning mainly low-dimensional Euclidean geometry) meet some real world applications. It contains brief descriptions of those applications and the geometric questions arising from them, as well as pointers to web pages on the applications themselves and on their geometric connections.
• The Geometry Junkyard These pages contains a collection of usenet clippings, web pointers, lecture notes, research excerpts, open problems, geometry papers online in non-geometric locations, and other stuff related to discrete and computational geometry.
• Recreational Mathematics Recreation is in the eye of the beholder, and not everything here was originally intended as recreational by its authors. Like many, I was inspired early on by Martin Gardner's Mathematical Games column, which included a mixture of puzzles, silliness, curious/useless math, and quite serious (but not overly technical) math. In that spirit, I list here some web resources for recreational math.
• The mathematics of Fermat's Last Theorem an overview of some of the mathematics that has either been developed over the years to try to solve the problem (directly or indirectly) or else which has been found to be relevant.
• Devlin's Angle by Keith Devlin (at the M.A.A. site - updated on the first of each month)
• MathLand A weekly series of contributions from Science News writer Ivars Peterson highlighting links between math and everyday concerns. (at the M.A.A. site)
• This Week's Finds in Mathematical Physics Issues of "This Week's Finds" and other expository articles on mathematics and physics
