The first two World Science Festivals (WSF), in which Sloan played the initiatory role and then was one of two key early funders, have been major successes. The 2009 WSF sold out virtually every event and achieved massive media penetration. The WSF embodies the Sloan program in public understanding of science and technology and employs many similar modalities. All the institutions of higher learning in New York, along with the major art museums, science halls, cultural centers and performance spaces, play host to this city-wide science festival and bring their traditional audiences into the tent. Co-founders Alan Alda and Brian Greene appeared as hosts and eloquent spokespeople for the value and impact of science in our culture. This new request, at the same level as the first two years, includes $100,000 to support two new Sloan events for 2010 plus $100,000 earmarked for the development of a three to five year Strategic Plan and Business Development Initiative that will focus on the long?term growth, expansion and stability of the World Science Festival. The Foundation has supported the Science Festival Foundation since 2006 with total grants of $1,345,000.
