Arrival back in Rochester (the plane didn't make it all the way to the gate, due to the snow -- or something)

btw, do you know about Clebsch-Gordon coefficients?

I've heard of them referred to as Hahn polynomials (methinks). And yes, I used them somewhat in studying angular momentum, but my practice in calculating them is... rusty at best. Uhhh... there are some online calculators if you require that kind of thing, supposing you know (or need to find out?) your quantum numbers to define the system.

Are we talking about the same thing?
