It's my first time using mathematica.
I want to define a solution to hydrogen atom and save it, so that I can just use it whenever I want to. It seems like you have to define it everytime you start a new session. I was wondering if there is a way to define a function and save it, so that you can use it anytime. For those who studied quantum mechanics, don't you agree it would be nice to just type in n, l, and m and get a wave function? Thanks.
