If there is it must be something real obscure! Hey, I read in the book
Chaos that some guy discovered another important irrational number, like
e and pi, that comes up as a sort of 'octave multiplier' (if you get
what i mean) in bifurcation diagrams and other chaosy stuff.

I dunno. Probably has to do with Fibonacchi.
