The Goeppert Mayer Gauge - Episode 15: Photocycloaddition

Episode 15: Photocycloaddition

12/08/21 • 54 min

We're celebrating Dugan's recent JACS paper on copper-catalyzed photocycloaddition reactions by doing a Back 2 Basics episode on photocycloadditons that is really just an episode on that paper with a little bit of Woodward Hoffmann rules thrown in for good measure. But what is a podcast for besides self-promotion anyway? We return to some of our favorite topics, including X-ray spectroscopy and transient absorption, and discuss how a combination of spectroscopic techniques can be used to deduce photochemical reaction mechanisms involving transition metals. We also ask ourselves how a single methylene group can drastically change the fate of a molecule and how a single pandemic can drastically change the fate of a research project.

Episode 14: The Stern-Gerlach Experiment

This month is more Back 2 Basics as we discuss the famous Stern-Gerlach experiment. In addition to the classic version, we contemplate thought experiments, photonic analogs, spin pedagogy, cigar smoke, Nobel Prizes, interpretations of quantum mechanics, God, and approximately infinite universes. Did I miss anything?

Episode 16: Thermal Radiation

We're finally back, and this time we're talking everything thermal! After some brief updates, we dive into blackbody radiation, Planck's law, and selective emitters. Then Jay explains how to use these concepts to design incandescent lightbulbs that are actually twice as efficient as LED bulbs. Then we move on to one of Jay's all-time favorite ideas: passive daytime radiative cooling. And things get even crazier when Jay explains how to use the universe as a really great cold reservoir in a heat engine to get harness solar energy without any photovoltaics.
