There exist in nature many, many negative feedback systems that stabilize
structures, sometimes structures of considerable complexity.
It seems to me that this is the key point. We know that control
requires negative feedback, but what is negative feedback WITHOUT
control? Where does it occur?
For the benefit of my feeble mind, could you please lay out in
mathematical detail the simplest occurence of negative feedback in
natural systems? A harmonic oscillator in a certain domain?
Perhaps a private reply would be in order.
Thanks for the compliment, by the way.
