Philadelphia Inquirer: One evening last week, Derrick Pitts of the Franklin Institute planted himself and his telescope on the streets of Philadelphia, offering the passing crowd the chance to view the heavens. He was there to gauge interest in the upcoming first annual Philadelphia Science Festival, tentatively slated for 1528 April 2011. The festival is being billed as a community-wide celebration of science that “will feature lectures, debates, hands-on activities, special exhibitions, and a variety of other informal science education experiences for Philadelphians of all ages.” Apparently, his experiment was a success: About 200 people participated. “People were really jazzed about being able to see this,” he said. “Groups of people would stand around and talk about it themselves, and then look again.”
