Recently I spent a day at Fermilab and gave a talk on the topic ”What is a Law of Nature?” I had a wonderful time and thank the kind folks at Fermilab for their hospitality. You can now watch the video of the talk at the Fermilab website. Abstract of the lecture here. The handout to which I refer in the course of the lecture can be found here.
Links to video of other public lectures and the like can be found at my main website.
