Comment on Irrational

Yes. I would argue 1/3 does not exist in quantum either.
The problem is that something that doesn’t exist in our universe or reality doesn’t disprove anything in mathematics. Mathematics is abstract. It is rules built up on rules. It does not care about reality or anything
You can divide a thing made up of any multiple of 3 number of things into three. Say, divide twelve eggs by three that’s four eggs, rational division is justified by “I could have multiplied some numbers beforehand so now I can divide”, it’s the inverse of multiplication, after all.
But that only applies to rationals: The issue is that there’s no integer you could multiply pi with that would result in an integer… otherwise pi would be a rational number which it isn’t.

If you have three particles, 1/3 of that is one particle. No need to divide an indivisible particle.

But if I don’t have three particles, 1/3 requires division.

Right, but you can have exactly a third of some group of particles. You can’t have exactly pi of some group of particles I think is what they were saying
