The analytical engine was a proposed digital mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. [2] [3] It was first described in 1837 as the successor to Babbage's Difference Engine, which was a design for a simpler mechanical calculator.

Babbage went on to design his much more general analytical engine, but later designed an improved "Difference Engine No. 2" design (31-digit numbers and seventh-order differences), [9] between 1846 and 1849. Babbage was able to take advantage of ideas developed for the analytical engine to make the new difference engine calculate more quickly ...
Ada Lovelace. In 1840, Charles Babbage was invited to give a seminar in Turin on his analytical engine, [12] the only public explanation he ever gave on the engine. [13] During Babbage's lecture, mathematician Luigi Menabrea wrote an account of the engine in French. [12]
The notes are around three times longer than the article itself and include (in Note G), [64] in complete detail, a method for calculating a sequence of Bernoulli numbers using the Analytical Engine, which might have run correctly had it ever been built [65] (only Babbage's Difference Engine has been built, completed in London in 2002). [66]
Babbage argued that on the contrary, his experience programming the analytical engine, an early computer, enabled him to conceive of God that might design a complex, programmed world. [ 3 ] The book is a work of natural theology , an attempt to reconcile science and religion, and incorporates extracts from related correspondence of John ...
Among his notable publications: Sketch of the Analytical Engine Invented by Charles Babbage, Esq. with notes by translator Ada Lovelace (1842), which described many aspects of computer architecture and is considered the first modern example of programming. Both are available on Wikisource.
The use of the word Engine was in homage to Charles Babbage and his Difference Engine and Analytical Engine. Turing's technical design Proposed Electronic Calculator was the product of his theoretical work in 1936 "On Computable Numbers" [3] and his wartime experience at Bletchley Park where the Colossus computers had been successful in ...
