      At one time I knew pi to thirty places. Then I read somewhere that it really doesn’t need to be that precise. So for example, if you were measuring the circumference of the earth using π = 3.14159 vs π = 3.141592653589793 it only changes the circumference by fractions of a millimeter at this scale. I can’t measure a 24 inch piece of wood with that amount of accuracy.

        The circumference of the Earth is somewhat subjective at that scale anyway, since it also depends on where you decide the radius stops.

          Well yeah since we really aren’t a perfect sphere. Not to mention elevation, buildings, etc.

      Alpha Beta Gamma Delta Epsilon Zeta Eta Theta Iota Kappa Lambda Mu Nu Omicron? ? Rho Tau Sigma Upsilon Phi Chi Psi Omega

      Edit: Forgot about Xi and Pi, before and after Omicron respectively. Also swapped Tau and Sigma’s position.
