    NASA requires 15 decimals of pi for interplanetary navigation. On the range of 16 bn miles to Voyager 1 it gives them calculations being off by 0.6 inch. For universe-sized circles they need 37 decimals of pi.

    Trying to remember 100 digits of pi won't give you any advantage in cognitive functions apart from memorizing 100 digits of pi, for a little while. Better spend your time elsewhere.

      You think they are memorizing the digits of pi because it’s useful?
