Realism and Ontology in Quantum Mechanics and String TheoryDualities in physics have challenged traditional forms of scientific realism by undermining the idea that theories describe a unique underlying ontology. In this paper, we develop a new perspective…Richard Dawid, Guilherme Franzmann·Dec 18, 2025SaveLearn
Notes on Crowther and the "Interpretation" of Quantum Mechanics (arXiv:2512.14315)We read Karen Crowther's Another 100 Years of Quantum Interpretation? with two practical goals.
