not much

With the end of the semester, it has been two relatively research-free days, I am embarrassed to report. I did spend some time talking with LeCun and Barron about our galaxy modeling project. Blanton and I had some discussions with the deans and provost's office and sponsored programs about meeting the obligations incurred as we join SDSS-3. And Cedric Deffayet (Paris) and Spencer Chang (NYU) confirmed my suspicions that the Casimir Effect has a conventional explanation that does not involve vacuum energy density.
