The Grand Cinema's Science on Screen series pairs screenings of classic, cult, and documentary films with lively lessons by notable figures from the world of science, technology and medicine. Each film is used as a jumping off point for the speaker to reveal current scientific research or technological advances, providing the perfect combination of entertainment and enlightenment - even for the most science-phobic culture vulture. At 6:45 p.m., Dr. Steven Fradkin, coastal ecologist at the Olympic National Park, will discuss the science behind our state's coast, followed by a screening of the adventure drama, Kon Tiki, the retelling of one man's journey to traverse the Pacific Ocean on a balsa wood raft in 1947.  We fully expect Fradkin to warn against floating across the Pacific on a balsa wood raft.
