The famous exclamation “Eureka!” attributed to the ancient Greek polymath Archimedes, remains the go-to word for expressing exultations of scientific discovery. And eureka is the theme for the 12th annual, family-friendly Los Alamos ScienceFest that takes place from Tuesday, July 9, through Sunday, July 14, at various Los Alamos venues. It all starts with a free kickoff party at 6:30 p.m. at Ashley Pond Park (2599 Trinity Drive, Los Alamos) on Tuesday, July 9. On Thursday, July 11, the Los Alamos Nature Center (2600 Canyon Road) hosts a 7 p.m. screening of Stanley Kubrick’s quintessential work of science fiction cinema 2001: A Space Odyssey ($5 admission). On Friday, July 12, take an Atomic City Spy Tour at the Los Alamos History Museum (1050 Bathtub Row) and be regaled with tales of international espionage. Tours start at 10:30 a.m. and 1:30 p.m. ($15 for adults, free for children and teens 18 and under). On Saturday, July 13, an array of electric-powered vehicles will be lined up along Central Avenue. There’s no cost to see these marvels of technological ingenuity. This is just a taste of what the festival offers. For a complete schedule of events and locations, visit losalamossciencefestival.com.
