Speculation on cross-scale resonance


This is wildly speculative, but it seems possible to me that there is some kind of resonance possible across the natural "levels" of the hierarchy of Life.

Now, cross-scale phenomena are always weird - for example, how a snowflake, on a scale of a centimeter, maintains coherent growth based on some initial seed at a molecular level. It doesn't seem intuitive that that kind of thing should work, yet snowflakes are symmetric at large scale.

But, if there are indeed levels of life that have some physical intrinsic basis, as the spiral I sketched a few days ago, and if basic control structures are symmetric across scale, then there maybe some kind of feedback or resonance that crosses scales, or octaves, as harmonics do in music, or as Moire patterns seem to do. (A Moire pattern is formed when you look through, say, a screen door and a second screen door, and you appear to see a huge but fuzzy screen shaped pattern as sort of an interference pattern. ) It's your call as to whether that pattern is "really" there or not.

Resonant frequencies are always intriguing, as energy tends to concentrate itself there for complex reasons. And, there are places where stuff collects for reasons that are not apparent, the most fascinating to me being the Lagrange Points, These are points that are a result of the gravity between the sun, earth, and moon, that are locally "downhill" and any stray junk floating in space will tend to congregate and stay there. So, right out in the middle of nowhere there are 5 places where stray things tend to go, even though there is no planet or moon or anything there, at least to start with.

So, here's my mixed metaphor thought -- what if some kind of interactive resonance across scales made control loops at every scale slightly "downhill" from the surrounding territory, so that if some system at some level gets "close" to having a closed control loop, this resonance will act like an "attractor" and bring the parts into better alignment with no further outside effort.

If that were true, even though highly organized things in general are unstable and tend to decay or degenerate, maybe the base class of control loops, at any scale, succeed in being entrained by this resonance, or any harmonic of the resonance, and synch up to it, the way radiation in a ruby crystal synchs up perfectly to make a laser beam.

Entrainment is another weird and wonderful thing of Nature. If you look at the Wikipedia entry on entrainment, you see that the concept spans many different fields of science, from physics to brainwaves to geology. Basically, if two things in harmonic or cyclic motion are "close" to the same frequency, they both tend to move towards being exactly on the same frequency. Two people walking will tend to end up walking in step. Women's monthly cycles tend to synchronize with each other if they live together. The mechanism is subtle and not obvious, but the effects are quite real and common.

One web site puts it this way.

Entrainment is defined as the tendency for two oscillating bodies to lock into phase so that they vibrate in harmony. It is also defined as a synchronization of two or more rhythmic cycles. The principle of entrainment is universal, appearing in chemistry, pharmacology, biology, medicine, psychology, sociology, astronomy, architecture and more. The classic example shows individual pulsing heart muscle cells. When they are brought close together, they begin pulsing in synchrony.
So, my thought has run out of steam without coming up with any experimental test, but I like the idea that somehow control loops at different scales can reach across scale and tend to help each other find common or compatible harmonic frequencies that work just a tiny bit better than you would expect. The playing field is just a little bit tilted, hardly enough to notice in any given case, but over 5 billion years the effect is strong.

Another example of a "weak" force acting over a long time to have a visible effect is the undisputed fact that the moon revolves around the Earth, and rotates as it moves, in exactly the right ratio so that the same "face" always is pointed towards the Earth. It wasn't always like that, and it didn't start like that. But, over time, there was a very weak "coupling" between the Earth and the Moon, such that there was a very mild downhill direction defined pushing the moons rotational speed towards being entrained by such synchrony. With nothing to push back, over a billion years, this very weak effect dominated and now the moon rotates the way it does.

Rupert Sheldrake, I think, has writtena bout "morphic fields" and some theory that life effectively pushes on and reshapes other life or proto-life nearby. I don't think I buy where he goes with that, but the idea of entrainment synchronizing living things is an intesting one to keep an eye on.

All of this speculating is partly because of the rather remarkable observation that, in a world of decay, dominated by laws of thermodynamics and moving ever "downhill", LIFE continues a remarkably defiant journey of moving UPhill and becoming ever more complex and larger in scale of operation. Something, some principle, is probably staring us in the face there, to explain why entropy keeps losing this battle and Life keeps winning. On a local scale, our dishes tend to get dirty, as do our desks, and our filing doesn't do itself. On a global scale, however, things do seem to be getting more and more organized. This tension between local and global behavior needs attention, and I'm not sure that "survival of the fittest" explains it entirely well. I have no doubt in evolution, I just have doubts that we've understood all there is to understand about it yet.

This thing of Phase and phase-coupling is subtle, but my intuition keeps bringing me back to it as if there's something important there I'm missing. The idea of "phase locked loops" is also fascinating, but this whole subject is just to subtle for most people to care about. There are three ways of modulating a carrier wave in radio, for example - amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM). Most cars have AM/FM radios. AM goes a long way, but is subject to static from lightning storms. FM goes a short way, but is high fidelity. I'm not sure what PM is good and bad at, but I need to figure that out.

I came across this article if you just want a mouthful to add to your class homework paper: Wandering breathers and self-trapping in weakly-coupled nonlinear chains. It's not relevant in any way to this post.

Still, I'd love to understand what principle helps cells, or people, or nations, that appear to be moving downhill towards chaos, surprise everyone and emerge stronger and healthier as if it was the most natural thing. There are a lot of sick people and companies and countries that could use more assistance, and if we could figure out how to amplify that effect, at least it should help.

If there is an effect, of course. Which isn't yet proven.

Any ideas welcome. Please comment!

There are three applications of cross-scale resonance or "downward weakly-coupled" morphic / shaping fields that are most interesting.

One is what the impact is of a national or corporate leader on the behavior of the citizens or employees.

Another is what the impact is of a person's human-level qualities (mental health, spirituality, whatever) on the health of the cells and systems in their own bodies. How extensive is psycho-neuro-immunology and how could we BOOST the efrect?

The third is a theological question but also a practical one. If there is a God, and God works to reshape people through natural processes, how would we detect that and what would it look like, and are the tools to detect such effects well in hand and calibrated and working on the first two problems I mention in this comment yet?

All in all, top-down shaping over a long time period by a "weak" but constant force is a problem we can easily overlook but one that can dominate an outcome.

Henry Kaiser (of Aluminum and Health care fame) used to talk about an approach he had of being an "happy elephant" and just smiling but leaning on people in some direction. AFter a while, he said, they'd tend to move that way.

In the short run, we can "neglect" those terms. In the long run, however, like the wrongness in Escher's Waterfall, these weak effects may dominate.

And, of course, I leave out precisely the topic I'm trying to include. FEEDBACK is one of those "weak" forces that may only have a 0.01% effect -- but gets applied over and over and over and over with compounding interest.

IN feedback loops, what is "BIG" and what is "SMALL" are hard to judge. AGain, this is cause for optimism, because there may be EASY things we can do that, over a long time, have a huge effect on whatever system we're attempting to heal.

Wade said...

It's probably not a coincidence that the Institute of Medicine, talking about how to improve the delivery of health care by intervening at the small team level ("microsystem") suggested FEEDBACK as the method of reshaping behavior that would be most effective with the least effort.

I'm I'm wrong on this, I have good company.
