There are analogues to this in mathematics, for example, our formulation of the Fourier transform has limited precision but the physical phenomenon it relates to has no reason to be limited.
- jerf 7y agoThe limitations of the Fourier transform are intimately tied to the uncertainty principle: https://www.youtube.com/watch?v=MBnnXbOM5S4 https://www.youtube.com/watch?v=MBnnXbOM5S4 Reality does appear to be limited by the limitations of the Fourier transform.
- GoblinSlayer 7y agoNot so fast. The uncertainty principle has narrow conditions outside which it doesn't apply. If you don't satisfy them, you can game the whole system and measure anything you want.
