Gravitational waves, spin glasses and Higgs boson are examples of research that in recent years have won the Nobel Prize, all marked by a significant Italian contribution. Nevertheless, understanding the reasons for a Nobel Prize and the implications that these great discoveries may have in everyday life is not always easy. The third edition of PID@HOME, a free training course dedicated to middle school and high school teachers, which ended on Monday 21 March, focused on these topics. Organised by INFN and by Pearson Italia, the course, divided into three events, was attended by approximately 300 teachers, confirming the significant success of the initiative in previous years. The PID@HOME project was founded in 2020, thanks to the collaboration between PID and Pearson Italia, and is now in its third edition, with a total of over 550 teachers involved. PID is a training programme proposed by INFN that, since 2018, is addressed to secondary school teachers, and is organised in three training courses per year, held in INFN national laboratories. Each five-day course envisages theoretical and experimental lectures covering topics in nuclear, particle and astroparticle physics, with a focus on interdisciplinary aspects of research. In the autumn of 2021, after a two-year stop due to the pandemic, in-person PID courses resumed at INFN Legnaro National Laboratories.Gravitational waves, spin glasses and Higgs boson are examples of research that in recent years have won the Nobel Prize, all marked by a significant Italian contribution.
