Dear All:
Interesting. The amount of science that is necessary for making these defining decisions is rather high and in all specific cases requires experts in those areas.
I almost always agree with Hillary. Here I would not disagree, just add that there are many external influences on a earth-moon-sun subsystem. All of the planets, and for that matter moons, asteroids, planetary debris, solar wind, gravity flows, highly influence each other in astronomy and physics. So an earth-moon-sun set cannot be considered closed for treatments at their level. For that matter, the recent discovery that there probably is an undiscovered proto-planet sized object way out in the asteroid belt indicates how much all objects in the solar system interact with each other. That they could predict its presence, as they did two of our current planets, without even seeing it is evidence that none of these exist as a closed system component.
So is the solar system as a whole a closed system? Consider that the part of the galaxy arm that we reside in is rotating, and the entire galaxy is moving -- all further influenced by gravity and dark energy and dark matter -- there is no way to even call our solar system a closed system. Then there is the influences of the black hole at the center of our galaxy, the expansion of galaxies away from each other, rare but existing galactic collisions and one galaxy eating other smaller ones, etc. etc. All these impart velocity and direction to our little solar system.
The observation that computer models are often closed systems falls in line with my previous comment that we simplify in order to make it possible to follow more limited interactions. But that doesn't mean much more than we should always recognize the limitations of our computer models and even our much vaunted equations relative to where and at what scales they can be helpfully and reliably applied.
I still have as a working hypothesis that there exists nowhere a completely closed system. Still open to receiving evidence though.

Earth plus moon plus sun is very close to a closed system for many purposes.
And computer models of systems are usually closed systems...

although we cannot be too sure of anything, these days it looks to me that most issuesare about definitions and boundary setting.
one of the reasons why I put 'goal setting' at the top of any modelling exercise(ontology, system or otherwise) is because the exercise must serve a purpose(otherwise its speculation and can be fun, but can also be annoying because some definitations and boundaries may work in some cases but not in others)
that means, putting humans and beavers in the same category (animal)or separating them (animal vs human), and everything else we do,is driven by whatever is the task at hand
so it depends, Steve, Mike, Jack, Len-why do we need the definition we are looking for>what do we need to design a system for >etc=
I also not sure whether any system is truly closed, or truly open'when we think big enough, even the ocean is a closed system (with the earth atmosphere its boundary).
even that consideration depends where the boundary lies
I use the term natural system as in it exist without human intervention(artificial lake is engineered, natural lake exists alone) with whatever implications the distinction bring-
but wait a minute.... why do we live? why does anything appear to exist at all>?<lol>

If I remember correctly, the notion of open and closed system is well
defined
in literature

Yes, models are notional, and yes, closed and open are not necessarily
discrete but fuzzy notions
The metaphore I use to distinguish closed vs open is indeed the aquarium vs
the open waters,
where regulation of the variables does not take place naturally but by some
engineered control mechanism as Len says
I am sure there are exceptions

Is a pond made by a beaver an engineered control mechanism or takes place naturally?
MDSE <michael....@gmail.com>: Mar 11 08:38AM -0500
Anything in the physical realm, whether it was created by man or not is a part of reality. This differentiates man's conceptualization (models) from the real world; theory from reality. I find the term "natural" to be misleading. If a beaver builds a dam is it natural? If people build a dam ( say to catch fish for primal tribesmen) is it natural? If people build a dam to generate electricity is it natural? Is mans propensity for making tools natural? Does it matter?

The notions of open and closed are well worn conceptualizations. Use where useful, but beware. At the root of all mistakes will be lurking the assumptions.

As are natural and artificial. Perhaps the distinction is more interesting if you believe people came into this world rather than out of it. I recognize beavers as kin. :)

Interesting. From a biologists point of view the following....
Anything a beaver, or even army ants, or colonial termites make is natural because it is made by a natural entity. Presumably evolution has very strongly selected for that which is made by them by eliminating many other alternatives as they arose. This ensures that at least for the near term, such innovations are fit within the environment. Until the environment changes which it usually does in the very long term.
But then why make a distinction for humans? We have evolved also. We are natural entities. Why wouldn't anything we make be burdened with the term "artificial" than any other thing made by a tool- using social organism? Persons focusing only on these aspects would see the natural vs artificial controversy as empty and unnecessary.
Now, I did not make up that distinctions but do use it often. All human systems, including our socio-economic and socio-political institutions I consider immature artefacts. In fact, it was Nobel Laureate Herbert Simon, in whose honor NECSI grants an annual award, and whose famous book was titled, "Sciences of the Artificial" who first popularized use of the term.
Perhaps it is because scientists realize that anything man makes can be engineered so quickly that it is not subject to natural selection and evolution at first and then not even for a very long time afterward if at all. So products that reflect more greed than adaptation to context, more arrogance than fit within natural parameters, surround our civilization. This might give some meaning to artificial. Further, the distinction might lead to a regime in which prescription and values become an important part of the process, recycling and fit in environment and cost:benefit an important part of the process in addition to making a buck.

How could the atoms 'be' systems? Simply by humans afflicted with tenure needing it to be so and not having to exercise a few independent fallibility experiments.

"There is no recorded experiment in the history of science that contradicts the second law or its corollaries ..... ". Written to show that no experimental evidence has disproved the second law, by physicists G.N. Hatspoulous & E.P. Gyftopoulos in E.B. Stuart, et al (eds.) "Deductive Quantum Thermodynamics in a Critical Review of Thermodynamics", Mono Books Corp: Baltimore, 1970 p:78
(5) "There are no known violations of the Second Law of Thermodynamics. Ordinarily the second law is stated for isolated systems, but the second law applies equally well to open systems - there is somehow associated with the field of far-from-equilibrium phenomena the notion that the Second Law of Thermodynamics fails for such systems. It is important to make sure that this error does not perpetuate itself." Written by Professor John Ross (Harvard University) to indicate that if Earth is regarded as an open system, then the Second Law still applies to it (meaning that evolution could not occur). In Chemical and Engineering News, July 7, 1980 p:40
Paola, I never said anything about networked computer systems! I was talking about system models constructed inside computer systems. Such models are more often than not closed, or represent closed systems.

made by BBC (five 20-minute videos in the playlist) about Cantor, Boltzmann, Turing, and Gödel and I'm glad I watched it.Important to note that laws are man-made conceptualizations. They might or might not be valid.
Einstein did not “brake” Newton’s law”. He added understanding that limited its applicability.
Then Einstein did it to himself.
Another thought on open/closed.
The fact seems to be that there is no such thing as a closed system, but the idea is used for simplicity by humans trying to conceptualize something.
Seems to me that the terms Open and Closed are not really meaningful. The question is how open (or how closed?) is the system model we are constructing, and does the system model have enough I/O (openness) to adequately represent the problem posed.
So (IMHO) forget the open/closed debate. Not worth having. Instead, concentrate on the following:
· Identify the I/O you are including in the model
· Identify the I/O you are NOT including in the model
· Beware the I/O you are not aware of (unknown unknowns), which is where the problems will probably start.

I am questioning whether the symbol, systemness, was devised by humans or demonstrated by nature before humans devised the symbol or was established by nature without any involvement by humans.Thanks for your interest. Probably we will not resolve this with sentences. It may be possible if we formulated an ontology.Jack

I think your first sentence is a very concise formulation of one of the most basic dilemma's or disagreements in this thread of conversation. I know you and others are very admiring of ontology because it promises a look into the most fundamental level of being.
But I am afraid that is its definition but not its praxis from my worldview.
Ontology solves nothing compared to experimental testing IMHO.
Ontology asks the human mind to think about things and that mind can only conceive of things within its current neural nets and logical reasoning on them. That is very limiting. On the other hand, experiments ask nature how it works and demands we formulate our neural nets to conform to how the experiments indicate how it works (sun around the earth; earth around the sun; earth flat; rounded earth, etc. etc. ad nauseum).
Minus those, of course, who refuse to accept the results of the vast range of experiments that are consistent with each other across the wide range of science specialties.
Ontology presumes it can uncover how entities came into being and sustain their beingness.
Only by using human thinking about it. The sciences propose hypotheses on how entities (all levels of entities) came into being and then tests whether or not those mechanics would work.
Most of the past 50 or so origins of new scales in nature (new classes of entity) show mechanics that would work long before humans, or even multicellular life came about on earth.
The point is whether or not you are convinced systemness leads to the stability and sustainability of systems.
If you are convinced by about 400 years of science on the dynamics of numerous entities or phenomena, then systemness was here in our grand space-time scale tens of billions of years before our solar system was even formed, much less human thought to think about ontologies.
Now the limited expression of awareness of systemness is another matter completely. We are just stumbling into our awareness of what it means to become or maintain a systemness. So perhaps the symbol is human brain limited and is certainly crippled by our currently limited understanding. But the hypothesis of the natural sciences as a whole (astronomy, cosmology, physics, math, chemistry, geology, biology, etc.) is that systemness existed way back in time and not when we humans (much less other aliens) began to become aware of and investigate it.
So I vote for the last two of your propositions (which consistent with the above analysis), to wit"demonstrated by nature before humans devised the symbol or was established by nature without any involvement by humans.”
Except that we must acknowledge we are now trying to catch up to what nature was doing then and now.
