Mathematics and observation never match.
They match quite often.
People often use math to predict things, to design things, and then use that to complete a task.
It is just when you start using incorrect math that you start having lots of problems.
But I'm assuming you are saying this because the math of a FE doesn't match reality?
Like how you need to pretend flights aren't real to pretend your map can work?
Because in this world, matter behaves like waves until you observe it, and acts like matter once you begin to observe it.
If anything it would be the exact opposite.
With math, we can easily get exact results.
But reality is typically more messy.
And with quantum mechanics, the best we can get is probabilities.
But that is reality acting as a wave, not math.
We can see this program code in everything that is constant, from the most basic mathematical constant pi to the logarithmic constant e, from the Gauss constant to the plank constant.
These constants aren't code. If you want to pick on something like that, go for the fine structure constant.
Not simply results of numbers.
Those numbers which appear in reality, also appear in math, as a direct result of math without any need for reality.
Considering the fact that math is made up and that all numbers actually equal 1, does it really matter what pi actually equals?
That isn't a fact, that is pure BS.
