comment How can molecule of a few angstroms absorb visible light of a few hundred nanometers?
You made that animation? That is excellent and really needed on the internet. I used to be able to find some pretty good three-dimensional animations of the hydrogen orbitals in superposition, but I can't find them anymore. So your animation, which clearly shows the basic idea, is really useful.

comment Nodes in wave functions outside of the classical turning point
Yeah, it's a little hard to find because it's not listed as the Potential Well in the Table of Contents. Section 16-6, "Quantized Energy Levels".

comment What is predicted to happen for electron beams in the Stern-Gerlach experiment?
But I didn't make any claims about the results of numerical experiments.

You didn't read my blog posting, did you?

Okay, you can get two dots if you use a numerical computation. I meant you can't get two dots if you try to do the actual experiment.

comment Can nuclear transmutation be observed in real time?
People talk about doing the double slit experiment "one electron at a time", but all they mean is that the beam intensity is so low that the detection events are far apart. There is still no machine that shoots out single electrons at will. I talk about this in an essay I posted a few years ago on the FQXI site: "There Are No Pea-Shooters For Photons". fqxi.org/data/essay-contest-files/…

comment Interesting relationship between diffraction and Heisenberg's Uncertainty Principle?
you are so right. I don't know what their problem is.

comment Do ionisation of atoms release photons?
Actually, if hydrogen is a typical example, the UV transitions are the ones that end up in the ground state.

comment When combining three spin $\frac{1}{2}$ particles what are the corresponding states?
I didn't read your question carefully when I posted my answer (thanks for the upvote) but now I notice you list five states, including one with m=0. I'm quite sure that's wrong...there's always going to be an odd half-spin left over with three electrons.
