I’ll be in Providence, RI, tomorrow to give a talk at Brown at noon entitled, “Science Meets Talk.” I’ll be discussing the fascinating, troubling, and sometimes bizarre intersections of scientific research and the media. It will be at Metcalf Chemistry Lab Auditorium, 97 Waterman St.  Here are the details.

I’m about to fly to California for my talk tomorrow at the Sage Center for the Study of the Mind in Santa Barbara, “Soul Made Flesh: Neuroscience in 1659 and 2009.” Here are the details.

Hope to meet some Santa Barbarans. (Or is that Santa Barbarians? Suddenly I have visions old Saint Nick with a pole-axe.)
