Look, sure, we can't write out pi as a clean decimal, but we can express it perfectly through multiple different methods. Besides, pi exists because it defines the relationship between a circle's diameter and its circumference. Sure, pi is an abstract concept, but the existence of that mathematical relationship doesn't depend on whether some guy in a lab coat perceives it or not. Humans just picked a specific language to describe what's already happening.
Even if humanity vanished tomorrow, nobody would be calling it "pi," but circles and their ratios would still exist exactly as they are right now.
It's the same deal with numbers—they're just our way of mapping out patterns that are baked into reality. "1" doesn't exist without us, but the concept of "oneness" or having a single distinct object is a property of the universe regardless of us. So, numbers exist as a framework built on top of those truths, whether anyone is around to notice them or not.
"If a tree falls down in a forest, but no one is around to hear it, does it make a sound?"
Hmm... honestly speaking, I’m not exactly on "home turf" anywhere on this forum. As a universal Diletant, I don't really have a "home turf" at all, except for my narrow professional field, which I can't even write about here anyway. It's always a bit of a gamble for a Diletant to speak up publicly, no matter the topic. But hey, isn't the risk always worth the potential payoff?
I suspect that when it comes to numbers, you and I might be talking about two totally different things. I’m not denying a single point you made! Of course, we can express Pi with enough precision for any practical application you could ever need. But the actual concept of a "number" doesn't exist out there in the wild. Ratios don't exist in nature either. A ratio only pops into existence inside our heads once we start comparing things. And then, we stumble upon a ratio that’s a little tricky to express using our standard rules, so we start dreaming up ways to deal with it. We invent increasingly complex conventions just so we can define things a bit better.
It’s the exact same deal as with colors. What we call a "color" can be expressed precisely enough for every practical use imaginable. We can replicate that "color" whenever we want. Yet, the color we're talking about doesn't actually exist in nature; it's just a convention we use to describe the subjective result of our perception. It's like how we invented centrifugal force—we can measure it incredibly accurately, even though it doesn't "exist" as a physical object, but rather as another one of our handy little conventions to help us wrap our heads around how nature works.
The fact that our perception is good enough to let us navigate the world without constantly walking into trees or getting eaten by lions doesn't mean we've actually cracked the code of reality or that our definitions of its elements perfectly match the truth.
If we had actually achieved that, science, religion, and philosophy wouldn't have any work left to do! And as you know, they are all staying extremely busy. They're still happily tinkering away at definitions, trying to make them just a little bit better.
"If a tree falls down in a forest, but noone is around to see it, did it make a sound?"It did, sure, but even if we *are* standing right there, are we truly capable of perceiving what sound it actually makes?
There was once a famous author (who's a bit controversial nowadays, but used to be huge) who wrote about sailing along the Mississippi with a friend. They're out on a sailboat, and the friend spends an hour describing every single wind that blows through that region and how a sailor can use them. Every wind is unique—its strength, temperature, humidity, direction, reliability, and so on. There are probably two dozen of them. But the author admits, quite honestly, that his entire experience of those winds up to that point could be summed up in just one word: "blowing."
Now, you also have to realize that the image that sailor had of those winds is still essentially just "blowing," just on a much deeper level. The true picture is such that it's currently impossible to describe using any human tools we have.
And that brings us a little closer to the level where humans actually perceive nature and the skill with which we try to describe and define it.
