About

Il Colle di Galileo is the "display window" for the initiatives promoted by the agreement "Il Colle di Galileo – Galileo's Hill" among the University of Florence, CNR, INAF and INFN.
It publishes articles, by invitation only, both in Italian and in English in order to describe the main activities in Physics research taking place in several Institutions in the Arcetri area. Namely: Department of Physics and Astronomy (UNIFI), Galileo Galilei Institute for Theoretical Physics (INFN and UNIFI), National Institute of Optics (CNR) and Astrophysical Observatory of Arcetri. These include scientific reports of events like international conferences and workshops and highlights on the main results obtained by the research of "Galileo's Hill" institutes.
