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.
