Today is a historic day slow effers. As noted by our friends at SciAm.com:
[Square Root Day] 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. (In today's case, 3/3/09, 3 is the square root of 9—in other words, 32 = 3 x 3 = 9.) Square root days arise in every year whose last two digits are a perfect square, or a number whose square root is a whole number: The last square root day was on February 2, 2004 (2/2/04), and the next occurrence will be on April 4, 2016 (4/4/16).
Initial reaction here would be to laugh, yell out "dork!", or break out a calculator-and you're absolutely correct! But listen people, this happens nine times in a century, and the next one isn't until 2016. Show some respect.
