2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/226424I discuss some problems related to extreme mathematical realism, focusing on a recently proposed "shut-up-and-calculate" approach to physics (arXiv:0704.0646, arXiv:0709.4024). I offer arguments for a moderate alternative, the essence of which lies in the acceptance that mathematics is (at least in part) a human construction, and discuss concrete consequences of this--at first sight purely philosophical--difference in point of view.11 pagesGeneral Relativity and Quantum CosmologyHigh Energy Physics - Theorytext
