AI Thread Summary
The discussion revolves around the concept of measuring the length of a piece of string and the implications of zooming in on its structure. Participants explore the idea that while mathematicians may consider a string infinite in length, physical objects have finite sizes determined by their atomic composition. The conversation touches on fractal geometry, suggesting that zooming in reveals more complexity, yet ultimately, physical limitations exist. Questions arise about the relativity of measurement and whether other objects, like hair or metal, could also be seen as infinite. The consensus is that despite theoretical considerations, physical objects maintain a finite length due to their atomic structure.

I know the conventional way to answer this question is to measure its length in cm.

But then I thought everything is relative to another thing so the length of the piece of string is X cm relative to me but what if you zoom in on a section of string and measure the twists and turns... Then go further until you reach the atomic level.

Is it possible to zoom in further and further? Is there a limit you reach until you can't go any smaller? If so, why was the limit that size and what caused it?

I know mathamaticians consider a piece of string infinite in length but why doesn't it appear infinite to us? Is it because everything is relative? So if I was a microbe on that string all I would see theoretically is string... So maybe we exist on a piece of string much smaller than the microbe.

So maybe it's possible to zoom in an infinite distance until you reach a limit that's infinitely large like another universe that exists on that piece of string...

Why is it only strings that can be infinite? Why can't a piece of hair? a watch or piece of chicken?

I'm confused!

They do?

definately some strange assumptions there

I can't really see how zooming in on it would make any difference to how long it is
take a piece of string 1mm thick and 1metre (1000mm) long
for argument sake let's say for that diameter and length it takes 1 billion atoms
zooming in on a microscopic scale isn't going to make any difference ... its still going to be 1 billion atoms from end to end

and by that reasoning, it doesn't matter what the material is, a bit of string, a hair, a length of metal... It has a finite size because it has a finite number of atoms making it up

I think he has fractal geometry in mind- like measuring the length of a coastline at different scales. Zooming in would reveal more twists, humps, crinkles, etc. And if one were dealing with a purely idealized mathematical object that was self-similar at every scale, then it would be infinite in length. However, it is a physical object and there is a limit at the atomic scale.
 
It's exactly twice the distance from one end to the middle.
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand.
