Seeing as I mentioned solving the Schrodinger 'electron in a Hydrogen atom' situation, here's the result showing electron probability as a function of radius. Ground state then higher, more complex spherically-symmetrical solutions.
Here's a link to the relevant LB lesson file. which shows what it is all about and how it is coded.
PS JohnnyD Yeah, my first opamps used valves. Then discrete transistors- germanium then silicon. First i/c versions were SL701C and 709s and then 741s. Modern opamps are much better in every way!
