You have good points above, I will consider that further... I suppose some of the issue is trying to connect math with ontology.I have. The states-of-states hierarchy delineates information based on its level in the hierarchy.
You assume "everyone else's" use of "REAL" will effortlessly hold up to scrutiny, but that is clearly not the case. Most people don't give it any thought at all. The history of philosophy is littered with serious thinkers unfruitfully debating the nature of "REAL", and yet you expect some commonsense, unanalyzed notion of "REAL" to be the rigid mast upon which to hoist your ontological sail. Good luck with that!
As for the purpose of mathematics, I cannot speak. But I don know that for most professional mathematics, math is its own purpose. This has been the case for hundreds of years. By and large, mathematicians do not care about its applicability to the world in which we live. G.H. Hardy is the exemplar. Physicists have learned that wordly insights can be gained from exploring the non-worldly creations of mathematicians, but for most mathematicians, such insights are merely a curiosity.
I am certainly at odds with the above, and it has nothing to do with Euclid. (BTW, it's pretty annoying when you proclaim what is or isn't a staple in contemporary mathematics. You don't have enough experience with contemporary mathematics to make such claims. I barely do.)
When I write a proof in this thread, I do so to show the necessity of my conclusion, or the impossibility of yours. In other words, I'm not just writing proofs to write proofs, I'm using them to resolve our disagreements. I well know that a mathematical or logical proof is not the "full scope", but when you introduce a formal concept -- such as ℝ -- into the discussion, I will analyze it in the most appropriate manner, i.e., within the formal system in which it is defined.
You seem to have the idea that you can pick and choose "parts" of a formal system, use it as a foundation for your ontology, and discard the rest of the formal stuff that necessarily comes with it. It doesn't work like that. The instant you introduce Pi or the unboundedness of ℕ, you've brought in the entirety of their corresponding theories, because those things do not have any MEANING without the theory.
More "what if" questions. What's the point? There is an endless stream of "what if" questions -- they add nothing to the conversation. "What if space were a toroid?" "What if space were a 1D line?" "What if space were only in our minds?" If you think a hypothesis is worth exploring, then explore it!
GR doesn't say that space is "bent"; it says that a geometrical model of the universe is necessarily a curved geometry. There is a sh!t ton of scientific research that corroborates this model, so if you disagree with it, you have a LOT of work to do to explain all the phenomena accounted for by GR that Newton's theory cannot explain. It's not enough to ask "What if?" -- you have to offer an argument in order for me to consider questioning my belief in GR. Otherwise, there's no point in bringing up GR.
I understand that your conception of Pi gives you cognitive dissonance. As someone who used to have a similar dissonance, I am suggesting that the way out is to learn more math.
I don't understand the analogy. The parent prematurely calls the child a musician, a fairly normal behavior of boastful parents. What does that have to do with Pi? In any case, I'm hoping that you have revealed a crucial problem with your internal conception of Pi. Your use of "linguistically" suggests that you might be trying to conceive of Pi and ℝ and such within a natural language. This is a doomed plan of attack!
Natural languages (such as English) are woefully unsuited for expressing mathematical concepts. Sure, we can translate basic ideas fairly easily, but as the mathematical structures of study start stacking up on each other, it becomes increasingly difficult to "plainly say" what a mathematical object is. For example, I don't believe I could explain what a "sheaf" or a "tangent vector" is in plain English. In the definitions of each, there are too many references to other mathematical objects to find adequate English representation. Yet, mention "sheaf" to any algebraic geometer and she'll instantly know exactly what you're talking about, as if you had mentioned "car" or "dog".
I acknowledge that it's weird and even uncomfortable at first to divorce mathematical ideas from linguistic constructs, but it's an essential step toward understanding the highly abstract concepts in math. I thought I should mention that.
As for the rest of your rant, give me some meat. Don't just tell me that ℝ and such are bullsh!t, show me with logic.
In the case of pi, my thinking is ontologically based with respect to no machine making a distinction between value and representation, as you pointed out above with the 2D array being seeing as a 1D stream of bits (and to the hardware, no-D). So to say there is a “distinction” between info and its representation, when representation IS info, is precisely why I say pi is in state of dynamic flux, chasing higher degrees of finitude, vs. the integer portion of “3” which is static.
