[June 16th, 1986] The Smiths release their third studio album "The Queen Is Dead". One track, "There Is a Light That Never Goes Out", is an instant hit.

any other philosophers out there who are first generation college grads? (i am also one!)

Let's say a *Buddha spacetime* (impermanence at every event) is one with no local Killing fields. A *Heraclitus spacetime* (can't step into the same river twice) is one with no local isometries between any distinct points. Theorem. Every Heraclitus spacetime is Buddha but not the other way around.

Not sure who needs to hear this today but determinism is not a mysterious metaphysical notion. If you or a loved one are struggling with haecceities, hang in there and read this paper. You got this! (new work with Hans Halvorson and @jamesowenweatherall.com) onlinelibrary.wiley.com/doi/10.1111/...

There is a new interview with David Malament that was just posted to the AIP website. Check it out! repository.aip.org/node/151302

my new bumper sticker: leibnizian spacetime+heraclitus matter is more deterministic than leibnizian spacetime itself.

Had a lovely time on the "Theories of Everything" podcast! #philsci #philsky #physics www.youtube.com/watch?v=iGOG...

I wrote a Galilean dialogue w James Read on the hole argument and determinism. It is essentially a fruitful email exchange we had after we each had published papers diametrically opposed to each other. It was a fun project! philosophyofphysics.lse.ac.uk/articles/10....

New piece on "Heraclitus spacetime" out today! #physics #philsky #philsci iai.tv/articles/the...

What happens when you remove a carefully chosen Cantor set from time-rolled Minkowski spacetime? You settle a extendibility question posed by Bob Geroch 55 years ago!

Had an absolute blast writing this paper with Thomas, Hans, and @jamesowenweatherall.com! GR turns out to be way more deterministic than previously appreciated. The past determines the future not only up to isomorphism but up to *unique* isomorphism! 🤯

It is sometimes claimed that the "privileged coordinates" of geometric model (e.g. a relativistic spacetime) encode its "structure". In a paper just out in Philosophy of Science (open access), Thomas Barrett and I explore the limitations of this idea... www.cambridge.org/core/journal...

New issue out now! Featuring evolutionary transitions and cumulative culture, hole arguments and jury theorems, Galileo’s ship and best laid plans, distinguishing the indistinguishable, and so much more… Read it here: www.journals.uchicago.edu/toc/bjps/202... #philsci #philsky #hps

Two new papers out today on "determinism" co-authored with the foundations of (a)symmetries dream team: @jimweatherall.bsky.social, Hans Halvorson, and Thomas Barrett. #philsci #philsky philsci-archive.pitt.edu/24881/ philsci-archive.pitt.edu/24883/

#philsky #philsci Videos from the workshop on Symmetry and Structure that Clara Bradley and I organized in Irvine in September 2023 are now available online. Some very interesting stuff there! Enjoy! jamesowenweatherall.com/symmetry-and... youtube.com/playlist?lis...

New paper "On Privileged Coordinates and Kleinian Methods" just published online at Erkenntnis (joint work with Thomas Barrett). We investigate senses in which the "privileged coordinates" of a geometric space might have significance. link.springer.com/article/10.1...

"Heraclitus-Maximal Worlds" was just published in the Journal of Philosophical Logic (joint work with Thomas Barrett). Bumper sticker version: Einstein spacetime + Heraclitus asymmetry + Leibniz maximality = no empirical underdetermination
