The logistic equation is a math model of the behavior of a living system.

A very simple system can demonstrate very complex behavior.

In my view this is another example of general systems theory (GST) where a specific branch of science was generalized into mathematics and applied in many places.

However, this is behavior of a simple system, not a system of systems or an industrial system.

Have fun,

Joe

Hi Jack,

I think the metod is to follow the cascade of bifurcation which has the
universal mesure (a sort of the delta number which can be got from
experiment/experience)

The magics here is our ability to distinguish the related and unrelated
events -  where the bifurcated branchs (splitted paths) belongs one tree
(one way)

Sorry if it is too vague methafora - I do some urgent job right now

Yuri
