I just gave a talk here at the lab; the "lunchtime seminar". I was coerced by this guy in the administration office. He wouldn't let up until I said yes. I was nervous as hell, especially since I wasn't prepared at all. I used my old LPSC talk from March and just winged it. It didn't turn out too bad. I got to talk more about background and basic geology (what is a chert?) and didn't have to worry about offending anybody with my opinions. Plus I got free lunch and a hat!
