A reminder that I'm wrapping up my Columbia University lecture series tonight at 5PM, when I'm appearing onstage with Radiolab's Jad Abumrad at the lecture theater in Pulitzer Hall (RSVP here); and then I'm heading to Swarthmore tomorrow, to give a talk at the Lang Performing Arts Center Room (LPAC) 101 Cinema from 7-9PM. Both talks are free.
