It is with great enthusiasm that we announce the fourth edition of the Fundamental Physics School, which will take place from October 20 to 24 at UNESP – Guaratinguetá Campus. This school aims to explore aspects of fundamental physics, both from a conceptual and a methodological perspective. To this end, the event will feature the participation of experts from various areas of physics (Gravitation, Quantum Field Theory, Condensed Matter Physics, among others). The synergy between these different research communities has the potential to generate new ideas and projects aimed at understanding the fundamental aspects of Nature.
