Today’s XENON Collaboration seminar speaker is from Mainz University in Germany. Among its many research features, one of my favorite things about Mainz is the Mainz Institute for Theoretical Physics (MITP) which has an EXCELLENT YouTube channel of chalkboard lectures on a range of physics subjects. You get a deep dive in each subject, building to greater and greater detail over each speaker’s series of lectures. https:// youtube.com/@mainzinstitutefor theoretic1604
