Making Symmetry Explicit: The Limits of SophisticationSymmetry is often treated in philosophy of physics as an interpretive problem. A particularly lively dispute concerns local symmetries: do they indicate surplus structure that ought to be expunged,…Henrique Gomes·Feb 14, 2026SaveLearn
Scale Invariance, Variety and Central ConfigurationsScale invariance has received very little attention in physics. Nevertheless, it provides a natural conceptual foundation for a relational understanding of the universe, where absolute size loses…Maria I. R. Lourenço, Julian Barbour, Francisco S. N.

Intereses convergentes: los años previos a la visita de Einstein a la Argentina en 1925We analyze in some detail the years leading up to Albert Einstein's visit to Argentina, from the moment he rose to fame after the publication of the results of the 1919 solar eclipse, until his…Alejandro Gangui·Feb 4, 2026SaveLearn
From Florence to Fermions: a historical reconstruction of the origins of Fermi's statistics one hundred years laterAim of this paper is to retrace the path that led the young Enrico Fermi to write his paper on the statistics of an ideal monatomic gas.
