The following are source-derived descriptions of cultural representations of centrifugal governors. A statue inspired by the Boulton and Watt governor design stands in Smethwick, in the English West Midlands.[1] A centrifugal governor is part of the city seal and flag of Manchester, New Hampshire in the U.S. (where a 2017 effort to change the design was rejected by voters).[2] A centrifugal governor—described as an 18th-century industrial invention—features in Liu Cixin's science fiction novel, Death's End (from the Three-Body series),[3] where it is used as a metaphor.[citation needed]
