Here’s an observation that’s mathematically trivial but might not be widely appreciated. In kindergarten, we all learned Gödel’s First Incompleteness Theorem, which given a formal system F, constructs an arithmetical encoding of G(F) = “This […]

I’m proud to say that Nick Hunter-Jones and Matteo Ippoliti—both of whom work at the interface between quantum information science and condensed-matter physics (Nick closer to the former and Matteo to the latter)—have joined the […]
For anyone living under a rock with no access to nerd social media, Alain Aspect, John Clauser, and Anton Zeilinger have finally won the Nobel Prize in Physics, for their celebrated experiments that rubbed everyone’s […]
(1) Since I didn’t blog about this before: huge congratulations to David Deutsch, Charles Bennett, Gilles Brassard, and my former MIT colleague Peter Shor, and separately to Dan Spielman, for their well-deserved Breakthrough Prizes! Their […]

The same thing Salman Rushdie learned: either you spend your entire life in hiding, or eventually it’ll come for you. Years might pass. You might emerge from hiding once, ten times, a hundred times, be […]
Back in January, you might recall, Skype cofounder Jaan Tallinn’s Survival and Flourishing Fund (SFF) was kind enough to earmark $200,000 for me to donate to any charitable organizations of my choice. So I posted […]
Here they are [PDF]. They’re 155 pages of pure awesome—for a certain extremely specific definition of “awesome”—which I’m hereby offering to the world free of charge (for noncommercial use only, of course). They cover material […]
Way back in the covid-filled summer of 2020, I wrote a survey article about the ridiculously-rapidly-growing Busy Beaver function. My survey then expanded to nearly twice its original length, with the ideas, observations, and open […]
Several people have asked me to comment about a Financial Times opinion piece entitled The Quantum Computing Bubble (subtitle: “The industry has yet to demonstrate any real utility, despite the fanfare, billions of VC dollars […]
