In November I had the opportunity to participate to the CircleU Sandpit event in Louvain la Neuve, in Belgium. CircleU is a university alliance, of which "Università di Pisa" is part of, togeheter with many others, for the creation of an international and interdisciplinary circuit of common research and teaching practices. It was so refreshing to speak and exchange ideas with motivated colleagues and PhD students from all Europe. We were able to write and participate to a call for funding, bridging Science and Democracy. Unfortunately, our project was not selected, but we have good ideas, materials, and more important enthusiastic people to try again next time. I will surely keep the memory of a great experience with fantastic people. Moreover, I could teach how to play "Table football" (Biliardino) to talented students! Definetely, a teaching achievement I can be proud of!
