The mathematical and logical part is where "
PIE" consists of, first, "
Pi", the Greek letter «
π» as a mathematical transcendental constant that is the circumference of a mathematical circle divided by the diameter of that circle, and the mathematical transcendental constant "
e" as the natural exponential function that plays an important part on the analysis of geometric sequences of growth.
The mathematical connection is, in part, a view of man's effort to understand and reason with logically the reality of the world as it appears to exist.
That is, if the radius is
r then the circumference
c is as follows.

The area
a of a circle with radius
r is as follows.

The volume
v of a sphere with radius
r is as follows.

The letter "
e" in "
Pie" is associated with the transcendental number
e defined as the natural exponential function whose first derivative (slope) is itself, as expressed in the following equation.

The exponential constant
e plays an important role in geometric sequences of growth (positive or negative).
