Today Is National Pi Day

It is National Pi Day.  No, not the kind that you eat.

The infinite number, abbreviated as "3.14," has its own day.  Some say the digits, when seen in a mirror, look like their edible counterpart.  You be the judge.

According to a poll conducted by the Science Channel, more people are "in favour of" the pie that you eat, more than 55% saying that they prefer it to the Greek geometric icon.

Pi has been around for more than 4,000 years, the letters, "p, i" are used to denote "periphery / diameter," coined by William Jones in 1706.
