Hello, I'm studing the hydrogen atom and I found an unified presentation of orhtogonal polynomials in the book by Fuller and Byron. I would like to learn more about it but in the same spirit(for physicits not for mathematicians). Can someone give some references where to find more?

Hmm, for physics usually a book like Byron-Fuller / Arfken / Morse & Feshbach would do. However, when you see the subject from the mathematical perspective, you can go deeper, into Hilbert space theory or into the analysis of hypergeometric functions which are the most natural generalizations.
 
What do you mean, like Hermite polynomials? Bessel functions are also basically polynomials. And of course Legendre polynomials. I'd learn those, we use all those in QM.
 
Arfken and Fuller presents clearly like a problem of eingenvalues of a selfadoint operator(sturn Liouville system) then he analyzes the conditions for the equation to render polynomials solution and from this one obteins all polynomials solutions(Hermite,Legendre,Laguerre,etc.) in a single framework and not like separate cases, for instance one can obtein a general Rodrigues formula encompassing all cases. It is very interesting and all done without fancy mathematics. I would very much like to see more of this, I mean more details, expleined by another author to complement the excellent presentation of Fuller/Byron
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
