Many thanks to Stephan Hartmann for the invitation to visit LMU Munich. I had a wonderful time meeting colleagues across the university and was honored to give a Philosophy & Physics Colloquium talk, “AI Meets Philosophy of Science: Towards a Foundation of AI.” Link: www.youtube.com/watch?v=aMyk...

Grateful to @thebjps.bsky.social for featuring our recent paper and making it free to read! Glad to see philosophy of science in the news!

Excited to give a talk on observation typicality at the Centre for Quantum Information and Quantum Control (CQIQC, U of Toronto)! Looking forward to meeting Aephraim Steinberg and colleagues to discuss quantum foundations. Event page: cqiqc.physics.utoronto.ca/events/quant...

A super interesting paper on universal steering of AI models just appeared in Science, with striking evidence for the Linear Representation Hypothesis. Congrats Misha Belkin and coauthors! www.science.org/eprint/URRDN...

Grateful to @apaphilosophy.bsky.social for highlighting my @nature.com Comment coauthored with Mikhail Belkin, Leon Bergen, and David Danks. We argue that the artificial general intelligence (AGI) has arrived, and the evidence is clear.

My paper with Roderich Tumulka is featured in @newscientist.com! We prove that the quantum state of the universe is, in a sense, fundamentally unknowable. Nature keeps its deepest secrets.

Does AI already have human-level general intelligence (AGI)? Our answer in @nature.com today: Yes, AGI has arrived. The evidence is clear. www.nature.com/articles/d41...

Excited to give "AI Meets Philosophy of Science" talks in Arizona—today at @arizonastateuni.bsky.social , next Fri at @uarizona.bsky.social . Why does ML work so well? I argue it reveals abundant learnable structure in nature, motivating an expanded view of laws beyond fundamental physics.

Very happy to share that my paper coauthored with Rodi Tumulka has been accepted for publication in The British Journal for the Philosophy of Science! The result was unexpected and points to fundamental limits on knowledge in a quantum universe. arxiv.org/abs/2410.168...

Heading to my first NeurIPS, this time right here in San Diego! Lots of great sessions related to AI foundations! neurips.cc

My paper, “The Simplicity of Physical Laws,” is now out in Noûs. One of the hardest problems I’ve worked on. The solution came as a surprise. It’s also shaping my current thinking about the foundations of AI. Link: onlinelibrary.wiley.com/doi/10.1111/...

New preprint with Jeff Barrett! We derive the Principal Principle—rational credence should match known chance—without circularity. Key idea: statistical constraint laws (algorithmic randomness) + exchangeable priors (inductive assumptions) → PP. philpapers.org/rec/BARARE-9

New paper with Jeff Barrett coming out in @thebjps.bsky.social ! We develop new notions of probability and probabilistic laws. Years in the making. Next: a natural proof of the Principal Principle. Link: philpapers.org/rec/BARARA-17

Excited to be giving a talk on philosophy of science and foundations of AI at the National University of Singapore, hosted by the Department of Philosophy. It’s a special occasion for me—NUS is where I began my philosophical training as an undergraduate 15 years ago.

Looking forward to talking about exchangeability, algorithmic randomness, and the Principal Principle tomorrow at the Institute of Data Science at the University of Hong Kong! (Joint work with Jeff Barrett)

Debating laws of physics + metaphysics with my former PhD supervisor Barry Loewer on Theories of Everything. Plenty of disagreements, but always learning! Watch here: www.youtube.com/watch?v=xZna...

Just finished a semester-long reading group on my book with the All Milan History & Philosophy of Physics group, thanks to the amazing Silvia De Bianchi. Incredible discussions on laws of nature, simplicity, and cosmology. Grateful for the sharp questions & insights!

Lofty Math Problem Called Hilbert’s Sixth Closer to Being Solved www.scientificamerican.com/article/loft...

Had the privilege to visit Armin Schwartzman’s group @ucsdhealthsci.bsky.social (Halıcıoğlu Data Science Institute + Biostatistics) to talk about algorithmic randomness, exchangeability, and the Principal Principle. Great conversations on probability and AI foundations!

Honored to receive the APA’s 2024 Public Philosophy Op-Ed Prize for “The Preordained Quantum Universe” (Nature, 2023). Thanks to @apaphilosophy for supporting public-facing philosophy! #Quantum #Philosophy #APA2024

Very happy that my paper with @eddykemingchen.bsky.social is officially published with Synthese with open access. It was a great opportunity to survey the space of options when it comes to the Born Rule for Everettians, and see how density matrix realism generalizes them!

Happy to share that my paper with @eugenechua.bsky.social is now officially published with open access! 🚀 "Decoherence, branching, and the Born rule in a mixed-state Everettian multiverse" link.springer.com/article/10.1... Thanks to all who offered feedback!

Just found this (Italian!) YouTube breakdown of Laws of Physics by physicist @davidedebiasio.bsky.social on his channel Spazi Attorcigliati. He dives into the first 20 pages—ontology, nomology, laws as constraints. I'm honored! Thanks to #ChatGPT I could follow along! www.youtube.com/watch?v=UDBD...

Excited to talk about density matrix realism and a new result on observation typicality at the Chapman workshop on quantum foundations in two days!

Had a wonderful time in Berkeley, speaking at the Logic Group on Friday and the Metaphysics Workshop on Saturday! I presented two joint papers with Jeff Barrett—on chancy laws as constraints and deriving the Principal Principle from them. Great discussions and feedback.

Had a fantastic visit at Stanford—thanks to Elliott Sober and Thomas Icard for the kind invitation! Tomorrow, Linda and I are heading to Berkeley! Looking forward to engaging with faculty and students to discuss foundations of AI, algorithmic randomness, and the laws of nature.

Thrilled to see my book Laws of Physics as the most downloaded item on PhilSci Archive for the last six months—a title it has held since September 2024! Grateful for the continued interest and support from readers, colleagues, and the @philsci.bsky.social community. #PhilosophyOfScience

I’ll be giving an informal presentation tomorrow (Friday) from 2–3 PM in the UCSD Philosophy Department conference room on: "Algorithmic Randomness and Exchangeability: A New Proof of the Principal Principle" All are welcome!

I’ve been sitting in Mikhail Belkin’s graduate seminar on the mathematics of machine learning and learning a ton—there are some striking connections to philosophy of science! Excited to give a guest lecture and grateful for Misha’s invitation. #PhilosophyOfScience #MachineLearning #AI

Thrilled to share that Laws of Physics will be translated into Turkish! Grateful to Cambridge University Press for making this happen—excited to reach new readers! #AcademicPublishing #PhilosophyOfScience www.cambridge.org/core/element...

🎉 Congrats to Rose & Taylor for an amazing #GenerativeAI Summit at #UCSanDiego ! Had fantastic discussions, learned a ton, and left with so many open questions for philosophy of science. Loved Misha Belkin’s slide on LLMs’ four different answers to “Who stole the cookie?”

My first book, Laws of Physics, was published last year, and it has just been reviewed in Notre Dame Philosophical Reviews by Dustin Lazarovici. Huge thanks to Dustin for the fantastic review and thoughtful engagement with the ideas! ndpr.nd.edu/reviews/laws...

Thrilled to share that a paper I co-wrote with @eugenechua.bsky.social is coming out in Synthese! 🎉 The paper extends Everettian many-worlds quantum mechanics to density matrix realism—a super fun collaboration. Looking forward to more in the future! philpapers.org/rec/CHUDBA

Thrilled to share that my paper, "The Simplicity of Physical Laws," has been officially published in Noûs and is available open access. Exploring simplicity proved to be anything but simple! doi.org/10.1111/nous...

How could the universe be so secretive? Excited to share my new paper co-authored with Roderich Tumulka. When we first discovered this idea, I couldn't believe my eyes. Comments are welcome! arxiv.org/abs/2410.16860

New grant to study quantum foundations! Excited to collaborate with an interdisciplinary team. today.ucsd.edu/story/philos...

Honored to receive the APA Public Philosophy Op-Ed Prize for my paper, "The Preordained Quantum Universe" (Nature, 2023). Writing this piece and engaging with readers' feedback has been such a rewarding experience! www.apaonline.org/page/2024pri...

Glad to see that my work with @jimalkhalili.bsky.social on the decoherent arrow of time is featured in this New Scientist article by @kpc.bsky.social, alongside comments by Vlatko Vedral and Emily Adlam. www.newscientist.com/article/2457...
