Part of [[Charles Babbage]]'s [[Difference Engine]] assembled after his death by Babbage's son, using parts found in his laboratory. The brass parts were machined by the toolmaker [[Joseph Clement]]. Babbage never completed his difference engine, partly due to problems with friction and machining accuracy, but also because he kept changing the design. [[Henry Provost Babbage]] inherited the pieces following his father's death in [[1871]], and some years later in [[1879]] he assembled several working sections of the full machine. Possibly as many as seven assembled sections exist. This portion, in the [[Whipple Museum]] of the History of Science of the [[University of Cambridge]], demonstrates how the addition and carry mechanism works.In the photograph, part of the left hand side is obscured by reflections from the glass display case.----*Photograph © Andrew Dunn, 5 November 2004. *Uploaded to English Wikipedia November 6, 2004, by [[:en:User:Solipsist]].{{cc-by-sa-2.0}}[[Category:History of mathematics]][[Category:History of computing]]
