Pi celebration day 3-14

π (also written pi) is a mathematical constant whose value is the ratio of any circle's circumference to its diameter in Euclidean space; this is the same value as the ratio of a circle's area to the square of its radius. (src: wikipedia)


Celebration day is set as March 14 (3-14 in rememberance of 3.14 )

One of the jokes that people use to tell about Pi:

Q: What does a mathematician with eye cataract have?
