all these orchestrating and giving skills etc. -- are they more or less being developed by trying things out? or is there a better way?

I think of it as a good basis for functions on a perfectly spherical surface. Going down in levels of "l", you describe more and more details in terms of angular scale.

Thus, it's widely used in earth science and astrophysics, and anything that involves spherical symmetry (like a Hydrogen atom) -- in reality, nothing is a perfect sphere, but that's a very good approximation.

Neat!! thanks for sharing

Another masterpiece I am sure!

This is phenomenal!

Aha. Wonder if they ever actually used it xD
