The Alfred P. Sloan Foundation has given the Coolidge Corner Theatre more support for its “Science on Screen” program. It was announced Wednesday that the Coolidge received a two-year grant of $748,392 to expand the program across the country. “Science on Screen” features a film followed by a discussion with an expert who can give scientific context to the material. The next “Science on Screen” night at the Coolidge is Nov. 23, and will feature Francis Ford Coppola’s “The Conversation” with expert Susan Landau, professor of cybersecurity policy at Worcester Polytechnic Institute.
