To simplify discussion, I am responding separately to the several

topics included in your post.

STABILITY - MMT:

There exist in nature many, many negative feedback systems that

stabilize structures, sometimes structures of considerable

complexity. I chose a vortex as one familiar to most people, in the

naive impression that its structural stability would be such an

obvious expression of negative feedback as to close off the

discussion.

Unfortunately, negative feedback systems do not necessarily provide

stability. Please see my discussion in my post to Joslyn with the

subject, "VORTEX & JOSLYN."

The Coriolis force is one way that the laminar flow symmetry gets

broken.

This does not fit my knowledge of physics. "laminar flow symmetry"

and its "breakage" are new to me.

The water is what comes from the inflow, not the energy that is

involved in the vortex feedback circuit.

I do not understand this at all.

Again, see my remarks in "VORTEX & JOSLYN," as noted above.

Regards, Bob Clark
