When someone of his level wonders whether the unification of physics will always be beyond mortal minds, it gets you worried. (He went on to explain why he doesn’t think we are too dumb, though.) […]
Oops, I said my last post on the recent Foundational Questions Institute conference would be my final one, but I can’t resist just one more. At the conference, Gavin Crooks at Lawrence Berkeley Labs, who studies molecular machines and gave a great talk on how life balances time asymmetry with thermodynamic efficiency, showed this brilliant short […]
