Per Georg Scheutz's third difference engine. Inspired by Babbage's difference engine in 1834, Per Georg Scheutz built several experimental models. In 1837 his son Edward proposed to construct a working model in metal, and in 1840 finished the calculating part, capable of calculating series with 5-digit numbers and first-order differences, which ...
The Difference Engine (1990) is an alternative history novel by William Gibson and Bruce Sterling. It is widely regarded as a book that helped establish the genre conventions of steampunk . It posits a Victorian era Britain in which great technological and social change has occurred after entrepreneurial inventor Charles Babbage succeeded in ...
Babbage began in 1822 with what he called the difference engine, made to compute values of polynomial functions. It was created to calculate a series of values automatically. By using the method of finite differences, it was possible to avoid the need for multiplication and division. [156] For a prototype difference engine, Babbage brought in ...
Replica of the Difference Engine in the Science Museum, reconstructed after studies of Charles Babbage's original drawings by Allan Bromley. Most discussions of the history of computing start with Charles Babbage, and what we know about Charles Babbage's Difference and Analytical engines really starts with the scholarship of Allan Bromley.
This machine, which he constructed with his son Edvard Scheutz, was based on Charles Babbage's difference engine. In 1851 they obtained funds from government to build an improved model, which was created in 1853 (was roughly the size of a piano), and subsequently demonstrated at the World's Fair in Paris, 1855 .

Joseph Clement (13 June 1779 – 28 February 1844) was a British engineer and industrialist, chiefly remembered as the maker of Charles Babbage's first difference engine, between 1824 and 1833. Biography
Seth Bullock argues that Babbage's description of his difference engine in the chapter on miracles is the first evolutionary simulation model. Babbage argues that the engine could be programmed to generate a series of numbers according to one law, then at a pre-defined point, this could switch to another law, leading to an apparent ...
