It's Square Root Day (All Over Again)

It's 3 March 2009 (or 3/3/09), so that means that it's Square Root Day!

As pointed out in numerous media outlets, today is a big deal for math lovers everywhere. Why else would a prestigious publication like Scientific American cover it in a blog entry?

As SciAm's John Matson points out, the "unofficial holiday comes around but nine times a century, when the numbers of the calendar align so that the month and day are each equal to the square root of the year as expressed in two-digit form."

The last Square Root Day fell on 2/2/04 and the next will occur on 4/4/16 (and so on and so forth moving forward).

So get out there and party tonight, number buffs. After all, you've got seven years to recover.
