William Sanford "Bill" Nye (born on November 27, 1955), popularly known as "Bill Nye the Science Guy", is an American comedian, television host, science educator and mechanical engineer . He is best known as the host of the children's science show Bill Nye the Science Guy (1993–1997) and for his many subsequent appearances in popular media as a science educator . This national popularity led to Nye hosting the educational television program Bill Nye the Science Guy from 1993 to 1997 . Each of the 100 episodes aimed to teach a specific topic in science to a preteen audience, yet it garnered a wide adult audience as well. The show was somewhat popular as a school resource and is still used to this day. He has written several books as The Science Guy. In addition to hosting the show, he was also a writer and producer for the series, which was filmed entirely in Seattle. When portraying "the Science Guy", Nye wears a light blue lab coat and a bow tie and takes on the personality of an excited, jocular science educator. This popular image of Nye has been parodied by numerous sources, including the webcomic xkcd and the satirical news organization The Onion. In response to the fake headline "Crack Nearly Killed Me", Nye took the joke in good humor and sent The Onion an email thanking them for "dealing compassionately with this matter." His Science Guy persona appeared alongside Ellen DeGeneres and Alex Trebek in Ellen's Energy Adventure, an attraction that has played since 1996 at the Universe of Energy pavilion inside Epcot at Walt Disney World. He also has a voice-over at the DINOSAUR attraction in Disney's Animal Kingdom park, where he tells guests about the dinosaurs while they queue for the ride. In addition, he appears in the "Design Lab" of CyberSpace Mountain inside DisneyQuest at Walt Disney World where he refers to himself as "Bill Nye the Coaster Guy." .
