How do you use technology to create images of things that have no image? How do you choose what color a colorless virus should be? In programs on July 7 and 8 at the Smithsonian’s National Museum of American History, noted biochemist and artist/sculptor Edgar Meyer will examine the fascinating intersection of art and science and explain how he gives 3-D visions to the very small.

Meyer’s accurate models of the polio virus are on display in the museum’s exhibition, Whatever Happened to Polio? Meyer will present a lecture program Thursday, July 7 at 6:30 p.m. in the museum’s Information Age Theater (first floor, west wing). Seating is limited. The polio exhibition will be open at the conclusion of the program. On Friday, July 8, Meyer will hold gallery talks in the “Whatever Happened to Polio?” exhibition (second floor, west wing), at 1 and 3 p.m.
