"Think you can't change the world? Too late, you already have. It was changed for the better the minute you were born. There are more people than you can imagine who will never be the same because they came in contact with you, if only for a fleeting moment." ~Gail Purcell

Happy Pi Day!!

Celebrate Pi Day!

Pi, Greek letter (Ï€), is the symbol for the ratio of the circumference of a circle to its diameter.
Pi Day is celebrated by math enthusiasts around the world on March 14th.
Pi = 3.1415926535…

With the use of computers, Pi has been calculated to over 1 trillion digits past the decimal. Pi is an irrational and transcendental number meaning it will continue infinitely without repeating.
The symbol for pi was first used in 1706 by William Jones, but was popular after it was adopted by the Swiss mathematician Leonhard Euler in 1737.



Or watch a Pi video:




You could even have a piece of pie!!

(ok, couldn't resist!)

Hope you all had a great day..... I made my weekly pinwheels for the sew along, but otherwise didn't do much. Another howling wind and rain storm here in New England. I guess I should be happy it's not snow!
