Washington Post: The first annual USA Science and Engineering Festival drew a large crowd to Washington, DC, over the weekend. About 1 million people visited the more than 1500 free, interactive exhibits during the grand finale expo on 2324 October, according to Leslie Tamura of the Washington Post. The expo, hosted by Lockheed Martin, was put together by 850 science organizations, which included professional science and engineering societies, universities, and federal laboratories.
