We head to the very far end of the electromagnetic spectrum to tackle one of Dugan's favorite subjects, nuclear resonance spectroscopies.  No, not nuclear magnetic resonance - we're talking about gamma ray transitions between nuclear configurations. After a fairly exhaustive discussion of how little we know about nuclear physics, we get into the details of radioisotope Mössbauer spectroscopy, nuclear forward scattering, and even a little bit of nuclear resonance vibrational spectroscopy. How do nuclear spectroscopists achieve resolution more than thirteen orders of magnitude greater than the nuclear transition energy? You'll have to listen to find out! And be sure to stick around to the end to learn the surprising connection between Vanderpump Rules and the Fiery Furnaces's masterpiece Rehearsing My Choir.

Prof. Nate DeYonker from the University of Memphis takes us out of this world and into the vast expanse of space as we talk all things astrochemistry. Get ready to hear about molecules that seem like they shouldn't exist, spectra from extraterrestrial telescopes with almost frighteningly good resolution, and the challenges of quantum chemistry using quartic (!!!) force fields. Nate also gives us a primer on "Pauling points" before closing the show out with an incredibly moving tribute to the late Mimi Parker from the band Low.

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.
