In the last ten years I have given several colloquia in various occasions and to various audiences aimed at popularizing science. Many of them were given as PowerPoint Presentations which can be downloaded by the interested visitor of this site.

*Negli ultimi dieci anni ho tenuto molte
conferenze divulgative e presentazioni varie, in sedi accademiche e non. Molte
furono fatte come presentazioni PowerPoint e di queste il visitatore interessato
del website può fare il download*
