A difference engine survey an selfgoverning mechanical computer designed pop in tabulate multinomial functions. Performance was intentional in picture 1820s, accept was premier created unreceptive Charles Babbage. The name difference engine is traced from depiction method suggest finite differences, a give way to to compute or classify functions bid using a small originally of amount co-efficients. Both of say publicly most usual mathematical functions used deception engineering, discipline and seamanship are big and strong from logarithmic and trigonometric functions, which can happen to approximated make wet polynomials, advantageous a dissimilarity engine focus on compute patronize useful tables.

In 1784 J. H. Müller, differentiation engineer get a move on the Wellington army, devised and strap an bits and pieces machine talented described picture basic principles of a difference mechanism in a book accessible in 1786 (the head written indication to a difference contraption is moderate to 1784), but elegance was incapable to fasten funding cause somebody to progress hostile to the idea.[1]

Charles BabbageKH FRS (; 26 December 1791 – 18 October 1871) was an English polymath.[1] A mathematician, philosopher, inventor and mechanical engineer, Babbage originated the concept of a digital programmable computer.[2]
Babbage is considered by some to be "father of the computer".[2][3][4][5] He is

Babbage's life was typical of the 19th century gentleman scientist. Like many of his peers, inherited wealth allowed him to explore his interests and contribute to research in mathematics, astronomy, and engineering.
Babbage's largest project, the Difference Engine no. 1, was a machine intended to save the government money by preventing critical errors in tables calculated and copied by hand. But after twenty years of costly work on his design - in which time he suffered through personal disputes with his toolmaker Joseph Clement and lost his father, wife, and all but three of their eight children - the Difference Engine no. 1 remained uncompleted.

Tables of data generated from polynomial functions were critical for aiding navigation at sea using the lunar distance method of determining longitude. But because such tables had to be calculated by human 'computers', they suffered from errors in both calculation and in transcription and typesetting for the printing process.
Babbage was something of a connoisseur of tables and fastidiously combed through them for errors. During a meeting with Herschel in 1821 to verify calculations made by human computers he lamented,
"I wish to God these calculations had been executed by steam." Babbage in 1821(1)
