The Salk Institute opened its doors to more than 2,000 members of the community who attended Explore Salk on October 27. The free open house featured science booths, hands-on experiments for kids, self-guided architecture tours and poster sessions by high school students. The event also celebrated the history of the Institute and its founder, Jonas Salk, with a screening of The Shot Felt ’Round the World, a documentary about the development of the first safe and effective polio vaccine. Featured throughout the day were talks about Salk’s Harnessing Plants and Conquering Cancer Initiatives, the science of architecture, and the use of circadian rhythms to improve human health and help us age well. About 100 volunteers helped make this a fun and educational day for our visitors.
