Winter Break 

 It's that time of year again; there is snow on the ground, a fire in the hearth, classes at Harvard end today, and things at IQSS are settling down for a brief winter's nap (at least that is the way I imagine it - the fluorescent lights in my office ensure that seasons have no meaning), so posts to the blog will be irregular for the next couple of weeks.  We'll be back to our regularly scheduled programming in early January, but in the meantime, Happy New Year!
