What is Pi and why does it taste more like a number than a food? Also, why do people keeps stealing it off my open window ledge???? WTF PEOPLE?

π (sometimes written pi) is a mathematical constant that is the ratio of any circle's circumference to its diameter. π is approximately equal to 3.14 in the usual decimal notation. Many formulae in mathematics, science, and engineering involve π, which makes it one of the most important mathematical constants. For instance, the area of a circle is equal to π times the square of the radius of the circle.

Well if it is Pi (π) then that's a math number which equals to 3.14
