As part of the "Rocks of Ages" exhibition, Assistant Professor of Anthropology Lucy Johnson and engineer Are Tsirk, a graduate student at New York University, demonstrated the making stone tools and flint knapping in the College Center. The exhibition, organized by Johnson, Assistant Professor of Anthropology Michael Herzfeld and their students in Anthropology 298, combined archeological and experimental artifacts.  "Students get practical experience," Herzfeld said, "in handling artifacts. It gives them a sense of historical context, and having a demonstration like this makes it come alive."     The Miscellany News
