For some 50 years, architecture has been in the thrall of a so-called International Style. To architect/artist/anthropologist Mark Robbins, however, all architecture is local: Drawing on his recent book, Angles of Incidence, Robbins’ slide- and video-illustrated lecture, “Reading Architecture to Understand a Culture,” demonstrates how buildings and cities can reveal both social and individual character. At 8 p.m. at the Ripley Center’s Lecture Hall, 1100 Jefferson Dr. SW. $13. For reservations call (202) 357-3030. (MJ)
