-------------------

10:15 - ? (new record: 3:15PM!!)  Dr. Nima Arkani-Hamed, Institute for Advanced Study

"The Inevitability of Physical Laws"

Here's Jeremy's best attempt at taking notes during the talk. He broke with about 30 minutes remaining. If he ever understands what he wrote, he'll try uploading a better version.

Nima has done variants of this talk before. Here is one from the Institute for Advanced Study, where he works, that is more focused on Higgs, since it was 4 months after the Higgs discovery. This one was two years later, also at IAS, with a fair bit of overlap but also includes some of that cool "natural units" stuff that he did the first time he visited in 2018.

I never knew what this sculpture meant. Now I kinda do?..
