# Feynman point

In the base 10 representation of $\pi $, at positions 762 through 767 (after the decimal point) there are six instances of the digit 9, called the Feynman point. Physicist Richard Feynman joked that he wanted to memorize $\pi $ up to that point: 3.14159265358979323846264338 … 77130996051870721134999999… Such a recitation would erroneously suggest that $\pi $ is a rational number^{}, the quotient of two integers that happen to be coprime^{} to the base.
