Pleasure to talk with you.

Consider my questions little provocations, not that I haven't

mastered the fields of either science.

I humbly say I haven't, but who may arrogantly say he has?

In principle I believe (but I cannot prove my belief mathematically)

that the universe is deterministic materially speaking (foreseeable

I mean).

Sometimes the number of variables involved is so great (or not even

yet entirely known) rendering its determination impossible exactly

(at least using the numerical methods known).

More efficient mathematical methods may be invented in the future to

solve what's nowadays unsolvable.

On the other hand in cases where the will of the creatures is

involved the universe is non-deterministic: nobody knows whether

I'll raise my index finger now or not (that depends on my will alone

and not on anything material) or whether the dog next door will bark.

So the world is a combination of deterministic and non-deterministic

things and we're immersed up to our necks in this chaos.

Statistics only partly explains the worldly phenomena.

In other words I fully agree with you that Statistics is incapable

to give solutions to all things what-will-happen-next.

As I see Chaos Theory today is still in its tender infancy.

Much more will come in the next centuries/millennia to enrich this

gemstone of the human thought.

What, for example, will be equivalent of the invention of the

logarithms, the set theory, the calculus, etc. (things that

transformed Mathematics radically) in the field of Chaos Theory?

Your comments (and from other colleagues as well) are much welcome.

Best,

Geraldo
