Eric and Simona and the cake.

The title equation from the wedding invitation - it creates a "butterfly curve" which, Eric explains, suggests the butterflies he and Simona experienced on their first date.

Sonnet and I spend the evening talking to Bill, who heads the legendary math department at the Univ. of Arizona. Bill has an unkempt beard greying on the sides - I think of Paul Allen @ Microsoft for some reason. Nita and Alain worked with Bill and his partner Debs, also in the house, before moving to Oxford so Alain could run the Oxford Centre for Collaborative Applied Mathematics. I steer clear of anything with numbers. Instead we are pragmatic : how to perfect the martini. And the best place to drink them. Bill did a 3 year sabbatical inParis and we compare notes - he hopes to return but for now his kids at AU - "never say never," he winks.
