Pi Day... or should I say π Day?... is almost over. What's that? You've never heard of π Day? Neither had I until I read Alan Boyle's MSNBC.com CosmicLog science blog for today.
Strictly speaking, you should celebrate π Day at exactly 1 minute before 2:00 (am or pm will do, unless you're on a 24-hour clock).
Do check out the link to CosmicLog; in addition to linking the official Pi Day site, there are a plethora of interesting π-related links to dig through. One I found especially interesting was this one (though linking it from a π Day post rather gives away the puzzle).
Anyone want to help me organize a π-mile run next year (see #5 here)?
