Spherical harmonic

WebSpherical harmonics are used extremely widely in physics. You will see them soon enough in quantum mechanics, they are front and centre in advanced electromagnetism, and they will be among your best friends if you ever become a cosmologist. The presentation here will be fairly terse and dry: apologies! Applications will come in Chapter 10.
