and National Public Radio's Sunday Puzzler. This fantastic site is packed full
of interesting goodies, and there's a weekly math puzzle.
The puzzles presented here are selected for the deceptive simplicity of their statement,
or the elegance of their solution. They range over geometry, probability, number theory,
algebra, calculus, trigonometry, and logic. All require a certain ingenuity, but usually
only pre-college math. Some puzzles are original.
