What does it mean to change momentum into position?

If a wave function ψ(p) describes a quantum state by giving the amplitude associated with any momentum p, you can Fourier-transform ψ to get a wave function, φ(x), that gives the amplitude associated with any position x. It’s not a physical change, it’s just a redescription.

What information are green/yellow shades encoding?
-
Phase — or just sign, as the time-independent factor for this wave function can be taken to be real-valued.

If anyone could point me to a progression of books, online classes or other resources to get me up to a level where I could attempt to understand this I would appreciate it. I know the basic concept of projecting from higher to lower spatial dimensions, but not the math.

Stereographic projection isn’t complicated. Wikipedia gives the formulas for 3D to 2D, which generalise in the obvious way. https://en.wikipedia.org/wiki/Stereographic_projection#First_formulation … The other material requires polynomials, partial differential equations, and Fourier transforms at 1st year undergrad level.

Thanks, you made my day

it is nice to know that our brains are *protected* against this sort of knowledge...

Hmm, I actually didn't know you could so easily extend spherical harmonics to any dimension before your post. :-/ Beautifully written!
