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. NPR science correspondent Ira Flatow was the show's first host, later succeeded by David Heil, then assistant director of the Oregon Museum of Science and Industry. Peggy Knapp was a longtime field reporter and served as co-host in the 14th season. The last season was hosted by the team of David Heil, Dave Huddleston, Actress and Voiceover artist, Eileen Galindo, Brian Hackney and SuChin Pak, now a frequent host and pop culture reporter for MTV. An occasional short feature appeared called "Science of the Rich and Famous" in which celebrities appeared to explain a science principle; as examples, rock star Ted Nugent explained guitar feedback, Olympic Gold Medalist skater Scott Hamilton demonstrated the angular momentum of a skater's spin, Let's Make a Deal host Monty Hall demonstrated the science of probability, and Betty White showed how cats purr.
