It was another eclectic day at the APS Global Physics Summit. Here is a selection of highlights based on my stochastic sampling of talks.

  • I've written before about CISS (the chirality-induced spin selection effect). Joe Subotnik gave a neat invited talk related to this, based on something I'd never really considered. In physics we learn about the Born-Oppenheimer approximation, which basically says that electrons are fast and nuclei are slow, so we can often solve electronic problems without..
