• My friend Francesco, at the end of his PhD dissertation, wrote the appendix “Vito Volterra: scientist, patriot, antifascist”, which summarizes the life and ideals of the Italian scientist Vito Volterra. Volterra resisted the authoritarian regime that took hold of Italy in the early 20th century, embodying a firm scientific and moral integrity from which there is still much to learn today.
