Celebrate Pi Day with Lumia and Windows Phone

The mathematical constant Pi (3.1415 and in Greek, it’s“π”) is the ratio of a circle’s circumference to its diameter and tomorrow, March 14, is the annual commemoration of Pi Day. Let’s have some Lumia fun celebrating the most famous ratio in mathematics.

While simple in concept, pi is famous in part because it’s an “irrational number.”

As this explanation states: “Computer scientists have calculated billions of digits of pi, starting with 3.141
59265358979323…, but because no recognizable pattern emerges in the succession of its digits, we could continue calculating the next digit, and the next, and the next, for millennia.”

So in homage to Pi day tomorrow–3.14.15–here are some ways to celebrate with the help of Lumia and Windows Phone.
