  Analytical engine - Wikipedia, the free encyclopedia
The analytical engine, an important step in the history of computers, is the design of a mechanical modern general-purpose computer by the British professor of mathematics Charles Babbage.
The analytical engine was to be powered by a steam engine and would have been over 30 meters long and 10 meters wide.
Closely related to Babbage's work on the analytical engine was the work of George Stibitz of Bell Laboratories in New York just prior to WWII and Howard Hathaway Aiken at Harvard, during and just after WWII.

Luigi Menabrea, a young Italian engineer wrote up Babbage's lecture in French, and this transcript was subsequently published in the Bibliothèque Universelle de Genève in 1842.
It is generally considered the first algorithm ever specifically tailored for implementation on a computer, and for this reason she is considered by many to be the first computer programmer.

 "Was Babbage's Analytical Engine an Instrument of Psychological Research?" by C.D. Green
The Analytical Engine, for which designs began in the mid-1830s, was a much more ambitious project because it was to have employed then-recent developments in abstract symbolic algebra, thereby extending its range into the logical realm rather than being limited to the strictly mathematical.
Although she stops somewhat short of the explicit claim that the Analytical Engine is itself such a thinking machine, the clear intent appears to be to raises the possibility for serious discussion.
Indeed, one might argue that the powers of his Engines served to distinguish precisely between those aspects of the human mind that were thought to be merely mechanical and those that were regarded as being truly original, creative, rational, and ultimately divine in character.

Ada's description of the Analytical Engine, the set of instructions she wrote for it, and her speculations of its possible uses were published in 1843 in a collection of notes in Richard Taylor's Scientific Memoirs series.
While Ada's explanation of the Analytical Engine came too late for Babbage and any hope he may have had to construct it, her "Notes" were the first concrete description of Babbage's invention.
She emphasized the versatility of the Analytical Engine by providing numerous examples such as demonstrations of how it would compute trigonometric functions containing variables, examples of how the engine would do difficult problems without error, and most notably, her detailed example of how the engine would compute the Bernoulli numbers.

The machine was to be powered by a steam engine and would have been over 30 metres long and 10 metres wide.
In 1842, the Italian mathematician Menabrea, who had met the travelling Babbage in Italy, wrote a description of the engine in French, which was translated into English and extensively annotated by Lady Ada Augusta, Countess of Lovelace in 1843.

What ultimately kept him from building an Analytical Engine was not his inability to finish a project, but his inadequacies as a political man, as a persuader.
Engineer Joseph Clement was hired to construct the engine for the government, and to oversee the fabrication of special tools.
In Babbage's design for the Analytical Engine, the discrete functions of mill (in which "all operations are performed") and store (in which all numbers are originally placed, and, once computed, are returned) rely on this supposition of reversibility.

 Charles Babbage 4
The major problem with the Difference Engine was that all the pieces had to be in certain positions to start with or the answer would not be correct and the pieces had to be moved back to the starting position each time a new calculation was made.
The Analytical Engine was a non-electronic machine with an input device (punched cards), a memorydevice that Babbage called the store, a central processing unit called the mill, and an output device (a mechanical printer), designed to process all types of mathematical equations.
The Analytical Engine was never built because not only did the British government did not want to fund a new engine until the old one was complete but there were significant problems with the mechanical sophistication of Babbage's day.

 Charles Babbage (1792 - 1871)
Babbage's Analytical Engine was to be the world's first general use programmable computer, a machine designed not just for solving one particular problem, but to carry out a range of calculations ordered by its operator.
The Analytical Engine was to be programmed by a series of punched cards, (in much the same way as Konrad Zuse would instruct his Z-series machines in the next century) but would have no ‘inbuilt programming’, or specific purpose, as had the majority of machines designed in Babbage's time.
Charles Babbage watched as the Scheutz Difference Engine took out a gold medal at the Exhibition of Paris and, a few years later, was commissioned for the Registrar-General's Department of the same government that had abandoned his original research.

Again, it [the Analytical Engine] might act upon other things besides number, were objects found whose mutual fundamental relations could be expressed by those of the abstract science of operations, and which should be also susceptible of adaptations to the action of the operating notation and mechanism of the engine.
In addition to Ada's prescient comments linking the Analytical Engine to its potential use for sound and graphics she provided what might be justly called "the first computer program", a plan for the Analytical Engine to calculate Bernoulli numbers, a very complicated chore.

It must be assumed that the analytical expression to be operated on can be developed according to powers of the variable, or according to determinate functions of this same variable, such as circular functions, for instance; and similarly for the result that is to be attained.
In this manner we shall have a representation of an analytical development; and, supposing the position of the several terms composing it to be invariable, the problem will be reduced to that of calculating their coefficients according to the laws demanded by the nature of the question.
When once the engine shall have been constructed, the difficulty will be reduced to the making out of the cards; but as these are merely the translation of algebraical formulae, it will, by means of some simple notations, be easy to consign the execution of them to a workman.
