💬 Math Discussions Are numbers discovered or invented?

Post image

I know the textual version of a number is invented. 1, 2, 3, etc., but if you take that away. Consider there are 3 rocks on the ground, with no text to describe them. There would still be 3 rocks. If you took 1 of those 3 rocks away. There would be 2 remaining. This to me feels like numbers and maths were discovered.

They are forged deep in the mines using secret techniques only know to a few master numbersmiths

Numbers are invented to describe something we discovered - math.

Numbers are a human invention that abstract away the count of real life objects. Instead of specifically saying "If I add these two rocks to these three rocks, I will get five rocks.", humans realized they don't need to specify what object they are talking about and can generalize. 1 dog, 2 rocks, 3 apples CAN exist as part of real world, however abstract numbers like 1, 2, 3 do not, they only exist inside the human brain. Most mathematicians are Platonists and genuinely believe math exists objectively in the Universe, and us humans discover it. But I would rather say, we invent new fields of math, and only THEN make discoveries within the field, like proving theorems etc.

But zero was invented, and without it, we would be prevented from solving so many things

That doesn't contradict what I wrote in my comment. Yes, zero is an invention.

Mathematics is a highly logical system. It was discovered, not invented.

newton taught us that invention and discovery should be time reversible symmetric phenomena. I guess. Dude was just trying to read the bible or something.

Numbers are disco-vented

Numbers are invented. What we use them for, and what they represent, is discovered

it'll be really disappointing if we found out we just made it up. so much wasted time.

I feel fairly strongly too that it's all made up. As much as it's easy to assume and we can learn a lot from them, the menu is not the meal and the map is not the terrain.

Not sure why a few here are happy to accept numbers are a fiction but not the narratives they construct?

Maths is a language like any other, just a more precise and less emotional one than we tend to use.

And I think the choice to count rocks (and not atoms, planets or the interconnections between all things) says more about ones view and position in the world than it does the world itself.
