Yichen Luo & Eugene Y. S. Chua, De-Idealizing De-Idealization: Beyond Full Reversal - PhilPapers There is a question of whether de-idealization is needed for justified use of -- for 'checking' -- idealizations. We argue that the standard philosophical account of de-idealization has become too ide...

My paper with @yichenluo.bsky.social has been accepted for publication at @thebjps.bsky.social! We argue that standard pictures of de-idealization are themselves idealized, and develop a practice-first account of de-idealization for validating idealized models. Preprint: philpapers.org/rec/LUODDB

Thankful to be invited to present my work on atypicality in LLM-powered psychiatry (jme.bmj.com/content/earl..., preprint on arxiv) and be part of a roundtable dialogue on responsible AI in mental health. Human-centered AI w/ sociotechnical p.o.v., involving all stakeholders, is essential here!

Putting Pressure Under Pressure: On the Status of Classical Pressure in Special Relativity Much of the century-old debate surrounding the status of thermodynamics in relativity has centered on the search for a suitably relativistic temperature; recent works by Chua (2023) and Chua and Calle...

Happy to share that my paper on the special relativistic pressure has been accepted for publication in Synthese! It's the last (for now) of a trilogy of papers on the generalization of thermodynamics into relativity, and I'm glad it found a nice home.

1/ I am truly honoured and completely delighted to have won the 2025 Berggruen Essay Prize (English), for my submission “The Mythology of Conscious AI” @berggruen.org @noemamag.com berggruen.org/eu/news/2025...

✨Reminder✨ The symposia deadline for PSA 2026 is 15 January (this Thursday!)

I had an excellent time taking part in the inaugural round of this program in 2023 -- highly recommend it! Deadline: Jan 15.

Physicists have recently been "looking for work in quantum thermodynamics", but what would count as success? (To what extent) can quantum foundations help? My paper on these questions has been accepted at the @thebjps.bsky.social!

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

Asian Philosophy of Science Association (APSA) Conference 2026

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.

Asian Philosophy of Science Association (APSA) Conference 2026

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

ABSTRACT. The Tolman effect conflicts with ordinary classical thermodynamics, but is rarely discussed outside of relativistic cosmology. We try to better understand this effect from a foundational perspective and make five claims. (1) It was Einstein who first discovered the effect and his derivation helps us appreciate how robust it is. (2) The standard interpretation in terms of ‘local temperature’ leads to the breakdown of much of classical thermodynamics. (3) We can rescue thermodynamics using Einstein’s preferred interpretation in terms of the ‘wahre Temperatur’ but it too has costs. (4) The effect is best understood in terms of clocks rather than energy loss. (5) We sketch an interpretation of the effect in terms of a third novel temperature. Here, temperature—and thermodynamics—is defined only in relation to local clocks. In sum, we view the fragmentation of temperature in thermodynamics as a natural and expected result of the fragmentation of time in general relativity.

Just accepted:

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!
