Pariah Posted April 12, 2018 Report Share Posted April 12, 2018 We're doing subatomic particles tonight in QM. I'll let you know if I hear anything interesting.

Lemme know if you hear the term "valence quarks" and if that term offends your chemist's soul to its core. Pariah 1 Quote Link to comment Share on other sites More sharing options...
Pariah Posted April 13, 2018 Report Share Posted April 13, 2018 Nope, no valence quarks. Just the six normal kinds, plus leptons and bosons. We did get to see, from a QM point of view went you can't have two protons together without a neutron. Particle exchange is nuts!

I kind of expected that (from the usual progression of topics in a fast-overview quantum class). Back in grad school there was a molecular spectroscopy course (by & for radio astronomers) where doing that derivation front-to-back was a big chunk of the tail end of the course. This was back in the days, well, not the infancy of millimeter wavelength radio astronomy, but it was the early years of that discipline. Nowadays it's big business with ALMA operational.
