Burke Institute Lecture Series Week 9

From a channel Lumen includes in full: This is the official Caltech physics division channel, and it consists of hour-long colloquia and lecture series by leading researchers, recorded and posted for teaching and public understanding. Every sampled transcript shows a substantive expert talk or course lecture, and the untranscribed titles follow the same colloquium format. There is no entertainment, clickbait or promotional framing.

A 104-minute video from Caltech PMA's catalogue; the title names its topic.
