Happy Square Root Day!

Happy Square root day, to all of my engineering/math friends! :-)

Granted, it's not as much fun as mole day, but it's more rare (only 9 a century).

Just so you know, Square Root Day isn't the only humorous holiday celebrated in the math world. Pi Day is observed each March 14 (3.14), while Pi Approximation Day falls on July 22 (roughly equal to 22/7). The first Pi Day was observed in 1988 by staff at the San Francisco Exploratorium, who walked around in circles.
