Hackweek 2026: What happens when a physics lab stops research for ~two weeks
Research labs are exciting environments where we learn, discover and invent new things. But they can be weird as well. You can have someone who fabricates superconducting qubits or photonic circuits a...

Michael Roukes kicking off #FNS2025, going back 30 years to the beginning of NEMs. (explaining this paper arxiv.org/abs/2505.04574 which was then rejected by APL!)
The building committee gets a first look at the basement of the Ginsburg Center for Quantum Precision Measurement at Caltech. We're standing where a tunnel will connect Ginsburg labs to labs in neighboring Downs Laboratory. With me are Nick Hutzler, Rana Adhikari, Michelle Effros, and Dave Hsieh.
New paper out! We resonantly couple a superconducting heavy-fluxonium qubit ⚛️ to a macroscopic membrane 🥁 oscillating at a few MHz. ~300 repeated interactions let us track its quantum motion, observe back-action & probe non-commuting operators. Diósi–Penrose next? (1/8) arxiv.org/abs/2505.21481
Probing the quantum motion of a macroscopic mechanical oscillator with a radio-frequency superconducting qubit
Long-lived mechanical resonators like drums oscillating at MHz frequencies and operating in the quantum regime offer a powerful platform for quantum technologies and tests of fundamental physics. Yet,...

Big: The final version of a randomized, controlled World Bank study finds using a GPT-4 tutor with teacher guidance in a six week afterschool program in Nigeria had "more than twice the effect of some of the most effective interventions in education" ("equating to 1.5 to 2 years" of standard school)
These notes are amazing, just the right amount of detail and insight! Thanks!

I decided to make a website. I’ll post stuff on it every once in a while.

We press forward with determination, grounded in the values that have made us a trusted and effective advocate for ocean conservation. We lead with hope. The path may not always be straight, but our commitment and belief in humanity’s ability to come together and heal the planet is still unwavering.
If you are interested in quantum computing, I strongly recommend this insightful article by @caltech.edu student @robbieking1000.bsky.social calling for a "scrappier approach" to finding new applications. quantumfrontiers.com/2025/04/20/q...

OK- here we go. Sorry for the delay, I was not prepared for the exertion required in the thrill-a-minute adventure that is… CACAO FERMENTATION. Yes, this will actually take 5 days. After that two days of drying. I’m not making this up. Nothing happens. Really. You’ll see. Anyway, off we go!
Seamus Blackley@seamus.bsky.social · 2y agoIf you’re bored enough later today, I’m going to begin fermenting some cacao. 5-7 days of pictures that will not change, obscure temperature and microbial data, and bad jokes lie ahead. Get psyched.
