Sailing June 19

Author: Mark Watts

Nerdy type who enjoys mathematics, computer programming and web programming (including this site). Avid collector of degrees. Other interests are music, especially opera and choral, cryptic crosswords (only The Times Quick Cryptic, not the 15X15), sailing, skiing (cross country and downhill), hiking and biking. Used to also love running until poor knees let me down. View all posts by Mark Watts
