Stable facts, relative facts

A Di Biagio, C Rovelli - Foundations of Physics, 2021 - Springer
Facts happen at every interaction, but they are not absolute: they are relative to the systems
involved in the interaction. Stable facts are those whose relativity can effectively be ignored …

The relational interpretation of quantum physics

C Rovelli - arXiv preprint arXiv:2109.09170, 2021 - arxiv.org
The relational interpretation (or RQM, for Relational Quantum Mechanics) solves the
measurement problem by considering an ontology of sparse relative events, or" facts". Facts …
