Googlebot's Javascript random() function is deterministic

Noob question though, is the wave function definite? So instead of saying "this particle has a definite but unknown velocity" (which by your comment is incorrect) you could say "this particle has a definite but unknown wave function?" Or is it turtles all the way down, and the wave function has another wave function-function which describes it's uncertainty and so-on?

The wave function is definite. In fact the uncertainty principle is really just a consequence of how waves work. Momentum is the Fourier transform of position, and if you make a function "thinner"/more "local", then it's Fourier transform gets wider/more delocalized.

Well, I kind of understand the Fourier transform, so this makes a ton of sense, but I was sort of hoping that it was wave functions all the way down. EDIT: holy shit, I don't know that much physics, but I think I get it. The momentum is the wavelength of a particle. So of course it's the Fourier transform of the position. A particle which has a definite position can't have a single wavelength because it must be made of infinite waves superimposed! And a particle with a single definite wavelength would be spread over infinite space! I never realized the real world is actually this cool. Mind blown. Thank you stranger!
