"Pi, Greek letter (π), is the symbol for the ratio of the circumference of a circle to its diameter. Pi = 3.1415926535... Pi Day is celebrated by math enthusiasts around the world on March 14th." www.piday.org/


This is comprised entirely of my photos. Dedicated, as always, to Meshl, who introduced me to this magical holiday.


Here's what I did last year

    Gorgeous, fun, beautiful, perfect, happy, accessible -- wait, I have to take a breath -- collage of pi. We are big fans of pi in this house. My husband memorized it to 100 digits in high school in order to pick up chicks. My older daughter memorized the first 500 digits last year, I think to combat some of the stress of her first few weeks at college. And with all that, none of us knew it was Pi Day today except my younger daughter, who spent yesterday's math class in a contest to see who could draw the most perfect circle. (Me, I'm agog at all those awesome fonts you've collected and drawn on for this project. Too cool for school.)

    Wow, this is fantastic. I really love the colorful collection of digits and the pie in the center is wonderful. I wasn't sure how you were going to outdo last year's but I think you managed.

    Awesome :)

    hate to break it to you, but you're missing a 4 on the 9th row! There are two 4s after 749, so it should be 7494459, not 749459.

    Super cool photo though!
