the number that never repeats, never ends, and never apologizes for it
means Pi is the mathematical constant equal to the ratio of a circle's circumference to its diameter, roughly 3.14159 and stretching on forever without repeating.
from The symbol π is the sixteenth letter of the Greek alphabet, short for the Greek word 'periphereia' (periphery, circumference) — the very thing it measures. Though the constant was known to ancient mathematicians, the use of π to name it caught on in the 1700s, popularized by the Swiss mathematician Leonhard Euler. So the circle's most famous number is literally branded with the first letter of 'going around.'
