So, here's the plan.

Hang out in Bordeaux this week. Try to figure out where I am in this
city. Possibly even have Erin visit later in the week.

Head to Paris on the weekend to see Nicki and boot around there.

Next week, I'm off to Geneva, Switzerland for a conference commemorating
Sturm's bicentennary. It actually lasts from Monday until Friday (school
starts a bit later in the fall here, so I guess people can make that sort
of scheduling). I will be meeting up with my supervisor and taking in the
two-part conference; some history of Sturm's life and work, followed by
more of a proper Sturm-Liouville Theory conference.
