Castiglione Olona

We go frequently to Varese but last Saturday I visited for the first time the beautiful mediaeval village of Castiglone Olona, a few kilometers from the centre of Varese.

On a different matter, I used to accommodate guests  at a beautiful ex-monastery in Calolzio-Corte until I discovered that some were allergic to bells.

Interview with Bill Lawvere by Felice Cardone 2000

Going through my papers I found this mail-interview by Felice Cardone of Bill Lawvere made in 2000, on the role of cartesian closed categories in foundations. The interview contains important historical information and is particularly relevant today to developments in type theory. For the pdf file click this link.
