There is yet another lesson in all these numbers: if you are willing to
specify a very small variance, say one percent, then you can generally
find an "amazing" geometric or numerical relationship between any two
numbers. You just keep trying "amazing" relatonships until one of them
fits. After you find one, you then announce that it's incredibly
that your "amazing" relationship is due to chance, without mentioning
your "amazing" relationship is one of billions of possible "amazing"

This is not to say that all such relationships are bogus. I have a gut
feeling that Bode's law may have an underlying cause based on the
mechanics of the original solar accretion disk.
