Celebrate Pi

Pi (π) is the circumference of a circle divided by its diameter. This ratio is always the same, for every circle of every size. And it has an infinite number of decimal places. π is used for calculations involving diameter, volumes of cylinders, the double helix of DNA, waves, ripples, and spectra, the pupil of the eye, and rainbows, to name just a few. Here are some digits:

7260249141273. . .

It’s only once every 100 years that we can celebrate Pi day to ten digits. So celebrate Pi day on March 14, 2015 at 9:26 am/pm and 53 seconds: 3/14/15 9:26:53 (3.141592653)!
