Here are a few interesting sites that I've found in my travels: Mike Shackleford's math pages. I've done the first 106 problems, so feel free to send me comments Nick's Puzzle pages. This is another well-constructed site with a variety of puzzles with solutions. Definitions of the SI base units (essentially all units of measurement are defined relative to these units). This is the only repository of conversion factors for units of measurement that I have ever found, which is both comprehensive and accurate. Basically, they know which conversions are exact and they know which units have inconsistent definitions, and they don't introduce rounding error without telling you. Do not go to for this info!
