An experiement -- Would it work?

  1. May 16, 2015 #1
    If you had a perfect sphere, and pi was it's circumference, what would happen? Would it be complete? Would it grow forever? How fast would it grow?

    It's diameter would be 1 in the same units you used for circumference. Otherwise nothing at all.

    All spheres have Pi as the circumference if you arbitrarliy declare a unit system where r=1. That's what Pi means. The units we use (meters, feet) are abitrary and unnecessary and mathematically it is simpler to just use a unit of D=1, so C=Pi.

    Grow? Why would it grow? And how is this an experiment?

    I'm glad I'm not the only one who keeps confusing radius and diameter. :wink:
