An Alleged Tension between Non-classical Logics and Applied Classical MathematicsTimothy Williamson has recently argued that the applicability of classical mathematics in the natural and social sciences raises a problem for the endorsement, in non-mathematical domains, of a wide…Sebastian Horvat, Iulian D.

Quantum Logic and MeaningThis paper gives a formulation of quantum logic in the abstract algebraic setting laid out by Dunn and Hardegree (2001). On this basis, it provides a comparative analysis of viable quantum logical…Sebastian Horvat, Iulian D. Toader·Apr 17, 2023SaveLearn
Remembering Ludwig Dmitrievich Faddeev, our lifelong partner in mathematical physicsWe briefly recount the long friendship that developed between Ludwig and us (Moshe Flato and I), since we first met at ICM 1966 in Moscow. That friendship extended to his school and family, and…Daniel Sternheimer·Apr 15, 2023SaveLearn
A critique of one of Galileo's mental experiments and an explanation on why bodies fall with equal acceleration through the vacuumIn the famous thought experiment studied in this article, Galileo attempted to refute the Aristotelian hypothesis that heavier bodies should fall more quickly than lighter ones. After pointing out…Leonardo Levinas·Apr 13, 2023SaveLearn
How research programs come apart: the example of supersymmetry and the disunity of physicsAccording to Peter Galison, the coordination of different ``subcultures'' within a scientific field happens through local exchanges within ``trading zones''. In his view, the workability of such…Lucas Gautheron, Elisa Omodei·Apr 7, 2023SaveLearn
A decoherence-based approach to the classical limit in Bohm's theoryThe paper explains why the de Broglie-Bohm theory reduces to Newtonian mechanics in the macroscopic classical limit. The quantum-to-classical transition is based on three steps: (i) interaction with…Davide Romano·Apr 7, 2023SaveLearn
