Re: golden ratio, Pascal's inverse triangle, etc.

The strange and wonderful (sqrt(5)-1)/2 DOES appear
in another strange and wonderful recursive series:

sqrt(1 + sqrt(1 + sqrt(1 + ...) ) )
  = 1.618033....
  = 1 + phi

(I think phi is he name the Geeks, oops I mean Greeks,
gave it, anyway).

Ponder That one!

Actually, phi is (sqrt(5)+1)/2 = 1.618033;
(sqrt(5)-1)/2 is phi - 1.
