I mean, I said, okay, everything is very, very precise, and that's true, but it's never exact.

You know, these calculations we do that involve nine decimal places, they take a huge number of terms to calculate.

We do these perturbation series.

So we do a calculation and we do one part of it.

We don't expect to capture everything, and it gets it mostly right.

And then we want it to be more precise, we add more terms.

These are the Feynman diagrams, and they get more and more complicated.

The more complicated a Feynman diagram, the smaller its contribution is to your calculation.

So you can just do one Feynman diagram and get it mostly right.

You can add more and get it more correct.

It's a series and it converges to a number.

You never get there.

You never bang on.

Our calculations are always approximate.

They're shockingly accurate when you push them, but they're never the description of reality itself.

There always is a fuzz there.

You can never get to perfection.

So it takes a little bit of the shine off of like, well, the universe is doing this also.

Because it feels like, well, the universe has to eventually make a decision about what happens to this electron or that electron.

It can't do an infinite calculation, right, in finite time.
