Looking forward to 2-and-a-half talks next week w/ @yichenluo.bsky.social at PKU & CASIP! Yichen will share our current work on analogies and disanalogies between integrable quantum stat mech and classical TD, while I'll speak on the "work" concept in quantum TD, and classical TD in relativity.

De-idealizing De-idealization: Beyond Full Reversal
– Yichen Luo & Eugene Y S Chua

Abstract in alt text or read it here:
www.journals.uchicago.edu/doi/10.1086/...

#philsci #philsky

ABSTRACT. 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 idealized, but that this does not preclude the possibility of justificatory practices that show how models can be used to make inferences about the world. In turn, motivated by examples in physics, we provide a more expansive and practice-driven account of de-idealization by relaxing the standards for closeness to more realistic theoretical items, identifying at least three kinds of procedure for de-idealization: intra-model, inter-model, and measurement de-idealizations. These examples highlight how idealizations can be---and indeed have been---scrutinized within physics without appealing to the philosopher's idealized notion of de-idealization.

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!
