狂涨姿势－－3月14日是百年一遇的‘派’日

"pi" is a mathmatical factor. Area of a circle... Circumference of a circle... We who work in engineering and construction use "pi" on a fairly regular basis.

"pi" is defined as 3.1415926. Tomorrow is 3/14/15. So at 9:26 tomorrow morning, it will be 31415926... or "pi" day!!! It only happens once every 100 years!!!!

Don't you feel smarter now???
