Howzabout: go to Fort Smith, NT, Canada (or thereabouts, 60° N) Walk or swim as appropriate, measuring distance, due East until you get back to Fort Smith. You got back, so it must have been a circle, yes? Walk or swim to the N. pole, measuring distance again. Compute ratio of distances. I think both Pythagoras and Eratosthenes would be thrilled at the result. - Mark
