How is it that I only recognize 2 restaurants on this list (and haven't been to either of those)?! nytimes.com/article/best-r…

I received the NSF CAREER award! Needless to say, I am pretty happy about it. But what makes me really excited is that this will support my research on the entanglement bootstrap (EB) program! Here's a long 🧵 on the origin of the EB program, from my personal perspective.

Very excited to share these new results on #AI for #quantumcomputing from Q-CTRL Our team developed a new learning-to-rank technique that can dramatically boost the efficiency of "layout selection" necessary to run algorithms on real hardware arxiv.org/abs/2404.06535

I still find the idea of applying corporate management techniques to fundamental scientific research so funny. Like what do you mean I need to align my work to our quarterly OKRs, I'm trying to touch the mind of God over here.

The essence of great software is the quality of its abstractions. Great abstractions are indefinitely composable and stackable. They become a dependable foundation for future work, future thought. The best ones are so robust you never have to revisit them -- you can forget them

Leaving Meta and PyTorch I'm stepping down from PyTorch and leaving Meta on November 17th. tl;dr: Didn't want to be doing PyTorch forever, seemed like the perfect time to transition right after I got back from a long leave and the project built itself around me. Eleven years

Bombshell: Oliver Sacks (a humane man & a fine essayist) made up many of the details in his famous case studies, deluding neuroscientists, psychologists, & general readers for decades. The man who mistook his wife for a hat? The autistic twins who generated multi-digit prime

Here's an important question that we must contend with increasingly as AI-for-Mathematics pipelines become more commonplace: Why do we care about solving hard problems? Almost always, the answer is *not* because we particularly want the hard problem to be solved. (1/12)

We are pleased to share that using Gauss, we have completed a ~200K LOC formalization of Maryna Viazovska’s 2022 Fields Medal theorems on optimal sphere packing in dimensions 8 and 24. This is the only Fields Medal-winning result from this century to be completely formalized,
