A short piece now published on JME Forum, introducing, in brief, our paper on the ethical risk of LLM-powered psychiatry: blogs.bmj.com/medical-ethi...

Last day to submit abstracts! Please note that the deadline is in Singapore time.

Final call for papers for APSA26! Please share widely, and we are looking forward to hosting everyone in Singapore!

There's about a month left to submit something to the Asian Philosophy of Science Association's inaugural conference! Consider submitting an abstract, and encouraging early-career scholars (especially those from or based in Asia) to submit an essay for the APSA Essay Prize.

Wrote a short piece for the IAI, on my recent paper on black holes and global energy! Contrary to title, I don't claim to have the messy truth behind black hole physics, but I do think we can move (and ppl are) from idealized global approaches to quasi-local approaches, in search of deidealization.

Very happy to announce that the CFP is now open for APSA26: The Inaugural Biennial Conference of the Asian Philosophy of Science Association! It will be held at Nanyang Technological University, Singapore. The keynote will be Craig Callender. Submission deadline: 31 Dec 2025. URL: tinyurl.com/APSA26

My paper w/ Bosco Garcia (UCSD) & Harman Brah (UCLA) on the 'problem of atypicality' for LLM-powered psychiatry is now published at the Journal of Medical Ethics! Just as GPT5 is touting capability as "active thought partner"... JME link: bit.ly/jme-atypical... Preprint: bit.ly/atypicality-...

We are hiring in Philosophy at NTU! Open rank and open area call for tenure-track/tenured positions: philjobs.org/job/show/29338

Talks from the 2025 Foundations of Thermodynamics workshop held at NTU Singapore, co-organized with @wmyrvold.bsky.social, are now available on YouTube here: bit.ly/yt-ftd2025 Thanks again to all participants for attending the workshop and contributing to the lively and fruitful discussions! :)

It's a wrap! Many thanks to participants of the 2025 Foundations of Thermodynamics workshop for making it a great success. Glad that the first workshop I organized went smoothly :) I got helpful feedback on some new work on the concept of quantum work, and learnt so much from the other speakers!

Temperature falls apart yet again! Jokes aside, very excited to share that my paper with Craig Callender, "The Toll of the Tolman Effect: On the Status of Classical Temperature in General Relativity", was accepted for publication in the BJPS! Preprint available here: arxiv.org/abs/2507.10529

When two LLMs debate, both think they’ll win Absolutely fascinating paper shows that LLMs basically cannot judge their own performance. None of the prompting techniques worked arxiv.org/abs/2505.19184

Co-organized with @wmyrvold.bsky.social, the 2025 Foundations of Thermodynamics workshop will be held in NTU from 16-18 July 2025. We have a great slate of participants and I am very much looking forward to it! Attendance is free and there will be a Zoom option. Details here: bit.ly/3SxvSNi

Looking forward to being back in the Boston area, meeting old friends, and participating in a debate w/ Siddharth about my recent EJPS paper, "Not Quite Killing It", next Tuesday at the ngEHT's 4th History, Philosophy, and Culture working group meeting at Harvard's Black Hole Initiative! 😄

Last class for the philosophy of quantum mechanics! It was so much work since it's the first time I'm teaching this, but it was rewarding to see students leave the course with an appreciation of the open questions at the foundations of quantum mechanics and science 😄

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!

Finally caught up on Orb: On the Movements of the Earth. What a rewarding watch, esp. as a philosopher of science! It's a fictionalized pre-history of heliocentrism in the age of the Inquisition, and a rumination on truth, knowledge, faith, humanity. It's also beautifully written and crafted.

PSA Around the World 2025 - one week to the deadline. We look forward to receiving your abstracts.

Always nice to be back in Caltech. Looking forward to co-presenting with Craig Callender on the Tolman effect and the temperature concept in general relativity, at the &HPS10 conference this week!

The first article in the special issue @martinkusch.bsky.social and I are coediting is out! Thomas Uebel lays to rest various myths about the Vienna Circle views of social sciences, proving yet again that they were right about pretty much everything. #philsci #philsky #histsci #sts

In merging gen. relativity with quantum gravity, we risk losing time itself. The 'thermal time hypothesis' says time emerges thermodynamically—but does it smuggle in dynamics from the start? A new article by @eugenechua.bsky.social appraises TTH📄👇 link.springer.com/article/10.1... #philsci #philsky

Looking forward to meeting colleagues and speaking on this paper on idealization, de-Idealization, and asymptotic reasoning I wrote with @yichenluo.bsky.social (UWO), at Lingnan and HKUST in Hong Kong next week!

The Asian Philosophy of Science Association is planning to convene our first conference in 2026! We are looking for institutions, particularly in Asia, who are interested in hosting APSA26. If interested, please send us a proposal! Details here: www.philsciasia.org#13

I was invited to write an article for @iai.tv on the emergence of time in quantum gravity, based on some past work, recent work, and work in progress. I used to watch IAI lectures and debates all the time as an aspiring philosophy student, so it's a milestone to be able to contribute to it now! 😄

Can time emerge from thermodynamics? My paper scrutinizing the thermal time hypothesis is officially published with @springernature.com at @jgps.bsky.social! Full-text view-only link here: rdcu.be/d9fhd

My paper with @eddykemingchen.bsky.social has been accepted at Synthese! What if the fundamental state of the world is a mixed state? We tell a generalized story of decoherence and branching, and extend three proofs for the Born rule to mixed-state Everettianism. philpapers.org/rec/CHUDBA

If you're an academic who might like to write a longform essay for @aeon.co, I'm accepting pitches! I specialise in physics/astronomy/space, earth science, environment, and technology + more. #science, #physics ⚛️, #geosciences, #paleontology #astronomy, #philtech, #histsci, #SciComm #science

The future is microdosing gravity (lack thereof)

A new substantive revision of my Stanford Encyclopedia of Philosophy entry "Thick Ethical Concepts" is now live. #philsky plato.stanford.edu/entries/thic...

I'm hiring a 2-year postdoc to come work with me on any issue related to the philosophy of thermodynamics! Please DM me with any questions. Deadline for initial consideration March 3, midnight PT. Please share widely! Details here: philjobs.org/job/show/28502

My paper on black hole evaporation, idealizations, and de-idealization has been accepted for publication at the EJPS! Do black holes evaporate? I argue that one particular family of arguments for evaporation rests on idealizations that resist de-idealization: philsci-archive.pitt.edu/24578/

Happy to share a preprint on relativistic locality from EM to (particle & field approaches to) QFT that Chip Sebens and I have been working on for the past year, for submission to Alyssa Ney's edited volume on Everett & Locality. Comments and suggestions welcome! Link: arxiv.org/abs/2412.11532

Finally back in Singapore: had a productive birthday week in California! Returned to Caltech to finish a manuscript on LLMs, ethics & psychiatry w/ collaborators at a writing retreat, then visited UC Davis to speak about my works on relativistic thermodynamics (received great questions/comments! 😄).

First leg of this US trip complete! Learnt so much from my colleagues and had so much fun in New Orleans at the Everett and Locality workshop and #PSA2024. Next stops: LA for a writing retreat, and Davis for a talk!

Came across an idea generation spot on an evening walk -- no bad ideas here!

Busy two weeks ahead! Speaking at a workshop on locality & quantum mechanics, and on pressure & relativity at the PSA, both in NOLA. Then a writing retreat on ethics of LLMs at Caltech, and talk at UC Davis on relativistic thermodynamics. Hope to run into friends new and old, and please say hi! 😄

Looking forward to giving an invited talk on the ethics of LLM-powered psychiatry (joint work with Bosco Garcia and Harman Brah) at this upcoming symposium at the Singapore University of Technology & Design! sites.google.com/view/philper...

Yichen Luo (UWO) will be presenting a poster on our joint work "Check, Please! De-Idealizing De-Idealization with Asymptotic Reasoning" at Rotman's Pragmatism and PhilSci Conference! First draft will be ready in a few weeks' time (let us know if interested!). In the meantime, here's the poster!

Will be giving a talk at NUS in a few weeks' time on the status of classical thermodynamic concepts in special and general relativity, and what this teaches us about classical thermodynamics (and non-fundamental reality)!

The 1st general assembly of the Asian Philosophy of Science Association (APSA) was held today, and the constitution was unanimously passed. I was also one of seven candidates elected to join APSA's first governing board, under the presidentship of Liu Chuang (Fudan).

Officially the first day as an assistant professor at NTU Singapore! I had a great time chatting with some of my new colleagues @chongminglim.bsky.social and @terumiyake.bsky.social, and I'm looking forward to meeting others in the coming weeks 😄

Hello, security engineer that has installed CrowdStrike on thousands of computers. A thread on the outage and what is exactly happening. Here’s a quick explainer on what *seems* to be the cause of the CrowdStrike outage and why it happened so quickly.

10th Integrated History & Philosophy of Science Conference (&HPS 10), California Institute of Technology, March 27-29, 2025. Submit abstracts by August 18, 2024 (Website not updated integratedhps.org/events.html but submission link here: auth.oxfordabstracts.com?redirect=/st...) #philsci #histsci

My paper "The Time in Thermal Time" has been accepted at @jgps.bsky.social in a SI on time in the foundations of physics! It introduces and analyzes the thermal time hypothesis, specifically whether it can resolve the problem of time in quantum gravity. Link: philsci-archive.pitt.edu/23691/

In June I was funded by Caltech's LCSPP to host a micro-incubator on the possible ethical risks of LLM-powered psychiatry w/ Bosco Garcia (UCSD) & Harman Brah (UCLA/VA Psychiatry). We wrote a short blog post here: techpolicy.caltech.edu/2024/07/16/l... Paper to follow in coming months!

Just heard back that the first ever symposium I've tried to organize, together with Bixin Guo (Pitt HPS) / Yichen Luo (UWO), has been accepted for the PSA! Looking forward to seeing everyone in NOLA this coming November😄

Happy 2024 from LA!
