The next paragraph is a Spoiler pertaining to the book Contact by Carl Sagan! Don't read it if you want to read the book! In the book Contact by Carl Sagan, Ellie discovered a pattern in the digits that comprise PI. http://math.cofc.edu/faculty/kasman/MATHFICT/mf55-spoiler.html There is also valid arguments why such patterns are strongly favored to exist. This makes the quest a little more difficult to judge what should and should not be in a natural number stream. I'm trying to imagine myself what pattern one might find in the mandelbrot which shouldn't be there or was placed there deliberately. Would it be the discovery of a phone number that when called would play a recording telling you all the knowledge of the universe? But not before requiring you to reverse the charges. ;) -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
