Bye! At least I got an answer to my question.

Bye! At least I got an answer to my question. — Pieter R van Wyk

Oh, don't mind him. He's just a bit miffed his series of YouTube video lectures on philosophy didn't quite take off as he may have wished or expected. :wink:

Are you really that nice old man in your profile picture? What a fascinating life you must have lived. I do wish you'd share more, perhaps in the Lounge or Shoutbox? It's fine if not. Time is no commodity, for any of us, really. :confused:

@Outlander
Thank you for your kind words and yes the picture in my profile is actually mine. As for the "nice old man" ... that would depend on whom you ask: my grandchildren might agree, might not.

At the moment I do not have any more pertinent questions for this forum. I will comment on some of the other discussions though. It is difficult to share more of my work: 'If I show you a few pieces of a jigsaw puzzle, they are the only things that you will see - a few pieces of a jigsaw puzzle. I had to build the puzzle to the extent that the picture starts to appear for you to understand the picture that I see.' p232 How I Understand Things. The Logic of Existence

What exactly is the purpose, extent and method of the Lounge and Shoutbox? Could it help me get a decent, critical, honest review of my work?

What exactly is the purpose, extent and method of the Lounge and Shoutbox? — Pieter R van Wyk

Oh, my good sir, that depends wholly and entirely upon whom you ask! Some people consider the Lounge a metaphorically graveyard of sorts, where threads that are less than popular are sent to die. Others consider it a place to test one's ideas and theories to see how weighted they are, as far as value. Sort of a "throwing what have you at the wall to see what sticks" kind of free for all arena. As for me? I just use it to play Chess. :smile:

The Shoutbox is a bit of a random, sort of free-for-all chat. Not unlike the Lounge. Just a social element for "social-ness" sake, I suppose. That said, I've read many a great tale on such a venue. Just a place where if you have something on your mind you think others might find of value, no matter how small, so long as it's genuine, you might wish to comment on and just see what others have to say. Mutual engagement and mutual entertainment, one might reduce such to. Not unlike the regular forum, in which strict rules and prose are to be expected. Just a bit of a fun place really, to speak with others like-minded who may generally hold such concepts to a bit lower standard of necessity than the common person these days.

Could it help me get a decent, critical, honest review of my work? — Pieter R van Wyk

It most certainly could. Though, and I don't mean to impose, are you familiar with recording and uploading video? It might do wonders to get your message across. It's quite simple these days, really. Why, even opening up YouTube almost explains the process perfectly. One side note, however. This website has an odd reputation for people "promoting their work" (which, unlike yours, is generally not of high quality) so the site owner, and as a result his staff, tend to frown upon self-promotion in general. But if done with tact, subtly, perhaps in a link in one's profile or as I said, interesting and engaging videos, such might occur. Such might occur.

It's great to have a published author engaging here, I'm sure @Jamal would agree. That said, there's a bit of a taboo in regards to self-promotion as far as links and book names and whatnot. But anything short of that, let this venue be your oyster, not unlike the market squares of olde! :smile:

You think this is at all accurate?:

Our solar system is a finely balanced many-body problem, quite difficult to solve mathematically. A two-body problem can be solved analytically but a many-body problem can only be solved numerically. However, please consider the gravitational force exerted on system earth by the following celestial bodies and by system earth on these bodies:

F(sun) = 3.52E22 newton
F(moon) = 1.98E20 newton
F(Neptune) = 2.21E15 newton

In comparison, the worlds total population exerts a force of 4.86E12 newton on system earth.

If any of these celestial bodies would be "removed" from the solar system this fine balance would be catastrophically disrupted and the expected environmental disaster would not be a political talking point, it would be de facto. Or if our solar system evolved sans Neptune, our system earth would have evolved completely different to what it did. — Pieter R van Wyk

Really? :D

As for the "nice old man" ... that would depend on whom you ask: my grandchildren might agree, ↪I like sushi might not. — Pieter R van Wyk

I am not at all concerned about your character. Maybe you are a saint for all I know. Regardless, you are wrong. That is what matters here.

You think this is at all accurate?: — I like sushi

I tend not to involve myself in matters of which I am unfamiliar with. These are titles, vernacular, and above all formulae and mathematics I have never made the decision to study or be informed of, but above all remain ignorant of.

I do agree he is correct as to the "if one planetary body, no matter how minute or seemingly insignificant is removed, great disarray and unrest would follow" claim. I'm fairly certain that's scientific knowledge. Whether those great vanguards who protect such wish to promote it or not.

I suggest you learn a little about gravity first and the scales we are talking about. It would do next to nothing.

Gravity will be there. It was there before humans and will surely be there after. Why the rush? Why the offense at human error? You act as if you couldn't be an example of such. Couldn't any of us? At least at some point in life? :confused:

So we better not send anything from the Earth to the Moon or to Mars and leave it there, because doing so would result in the solar system flying apart.

Oh wait, we're doomed.

Maybe I should have been nicer.

I will keep in mind what you have pointed out here in the future.

No human being has ever created or destroyed a planetary body. That would be space debris. Or a satellite, at best.

You're a fun one, now aren't you?

I have been warned, quite sternly, about self promoting, but was informed that I may reference my own work. I am trying my level best to adhere to this, quite ambiguous, rule.

Interesting place, this forum. I ask a simple question about a definition of a system and end up arguing about absurd nonsensical planetary questions. How odd.

Is it really, though? They do call it "the solar system", after all. Surely there's some relevance. Fleeting or not. :grin:

@Outlander
Okey-okey, I get your point. But consider this:

We speak of the solar system.
We cannot agree on what, exactly, is a system.
We make the absurd postulate that one planet could be removed from the solar system.
This could tell us whether the solar system is in fact a system.

Which clever philosopher stated that from a false (absurd) statement, anything can be proved?

Regardless, you are wrong. — I like sushi

Yes, you are right (I am wrong); but then, anything can be proved from an absurd statement.

The Solar System is a system.

You were just factually wrong. Absurdity has nothing to do with this.

Pluto is no longer a 'Planet' it is a 'Dwarf Planet'. Systems can change without losing structure.

How I Understand Things. The Logic of Existence — Pieter R van Wyk

Ah. You have a self-published theory to push. And you don't seem to have any interest in placing it within the 2500 year old tradition of systems thinking. Explains a lot.

"If and when we consider things, contemplate things and try to understand things, we can consider anything. In doing this we must convert some anything into something. And there are only two ways we can do this: First we could designate some name (perceive some possible purpose) to some collection of anything and then contemplate some valid description of this specific collection. If we can agree on the unique things in this collection we have named, we could have a meaningful conversation about something. This is then the notion of a system, how we understand all physical things, even those physical things that give us a perception and an understanding of abstract things. Let us name this Systems-thinking, for future reference.

If it is not possible to name something and agree on its constituent parts - we could consider some anything in terms of something else. If we could agree on such a relationship, a meaningful conversation could also ensue. This is how we form an understanding of all conceptual things. And this we could name Relation-thinking for future reference. — Pieter R van Wyk

So far, this is rather rudimentary. But it does lean towards the kind of distinction that a contemporary systems thinker like Stanley Salthe makes. The difference between compositional hierarchies based on the relation: "Is-a-part-of" versus subsumption hierarchies where the relation is: "Is-a-kind-of".

I'll let AI generate an instant summary for you....

Stanley Salthe distinguishes compositional (or scalar) hierarchies, which are based on spatiotemporal scale, from subsumption (or specification) hierarchies, which are based on developmental history or logical relationships. The two models help to analyze complex systems from different perspectives.

Compositional (or scalar) hierarchies
This hierarchy is based on nested parts of a whole, defined by differences in magnitude, size, and rate of activity. It provides a snapshot of a system at a given moment in space and time.

Relationship: "Is-a-part-of".

Structure: Portrayed as boxes within boxes, or levels within a system. For example, a population contains organisms, which contain cells, which contain macromolecules.

Dynamic relationships: Lower-level components are constrained by the next higher level. Importantly, downward regulation is not transitive across the entire hierarchy but must be converted at each level.

Way of knowing: Understanding a system involves subdividing it into its constituent parts (a reductionist approach).

Subsumption (or specification) hierarchies
This hierarchy is based on logical or historical sequence, where earlier, more general conditions are subsumed by later, more specific ones. It describes how a system develops over time or how different fields of knowledge build upon one another.

Relationship: "Is-a-kind-of" or "develops-from".

Structure: Portrayed as nested brackets, with more specific classifications contained within more general ones. For example, the biological world is a special type of the material world, which is itself a part of the physical world: {physical world {material world {biological world}}}.

Dynamic relationships: Control or influence from a higher, more specific level (e.g., biological forms) can extend down through all lower levels (e.g., physical forces), as the higher levels impose new informational constraints on the lower ones.

Way of knowing: Understanding a system requires looking at its history or ancestral conditions.
