Get all scientifical about your readings and whatnot and learn how you can't escape the Rennaisance even in the Bitterroot at the Opening Reception of Harry Potter’s World: Renaissance Science, Magic and Medicine. This ain't a dry affair. There are witches, wizards and muggles, too, along with Professor Garon "Gee Wiz" Smith from the UM Science Department and the Hamilton High School Choir singing Renaissance music. The exhibit is a collaboration with Rocky Mountain Laboratories and the National Institute of Health. Ravalli County Museum, 205 Bedford St. 6–7:30 PM. Free.
