I have a few questions about this question:

(1) What is chaos in the mathematical sense?
(2) What is a system (in the OP's sense)?
(3) Supposing that Q2 has a satisfactory answer, what does it mean for
(such a) system to have feedback?

I know nothing about the matter, but it seems to me that one can have
chaos (in the mathematical sense) in contexts where 'feedback' has no

Also, (4) _are_ the primes chaotic in the OP's sense?

[Yes, I could answer Q1 by looking it up, so take the Q to be... um...
"Socratic", if that doesn't sound too pretentious.]
