Newton's Apple
8.00 30 minutes Newton's Apple is an American educational television program produced and developed by KTCA, and distributed to PBS stations in the United States that ran from 1983 to 1999. The show's title is based on the rumor of Isaac Newton sitting under a tree and an apple falling near him—or, more popularly, on his head—prompting him to ponder what makes things fall, leading to the development of his theory of gravitation. The show was produced by Twin Cities Public Television. For most of the run, the show's theme song was Ruckzuck by Kraftwerk, later remixed by Absolute Music. Later episodes of the show featured an original song.
An occasional short feature appeared called "Science of the Rich and Famous" in which celebrities appeared to explain a science principle.
