Dear Brij, A little while ago, you shared with us some fractional values of � that you had collected and I remarked that if you write the number 113355 with the last three digits as the numerator and the first three digits as the denominator then you get a very good approximation for �.
355/113 = 3.1415929 Now to get to the metric bit that might be relevant to this list. Last night I calculated the distance to the Earth's horizon from a height of 1�metre above the ground. The result came to 3.57�kilometres. 1�metre 3.57 kilometres That's an odd numbered pattern! Cheers, Pat Naughtin LCAMS Geelong, Australia
