) Henry Babbage's " Analytical Engine Mill " is on display at the Science Museum in London.

* In the Neal Stephenson novel The Diamond Age, ubiquitous molecular nanotechology is described to make use of " rod logic " similar to that imagined by Babbage's design for the Analytical Engine.

This short story follows Holmes as his program is rebooted on modern computers and he is forced to compete against his nemesis yet again in the modern counterparts of Babbage's Analytical Engine.

The Engine is not a replica ( one was never built during Babbage's lifetime ); therefore this is the first one-the original.

Although the " printer " is here referred to as such, its primary purpose is to produce stereotype plates for use in printing presses ; Babbage's intention being that the Engine's results be conveyed directly to mass printing.

While it is theoretically possible to implement a full computer entirely mechanically ( as Babbage's design showed ), electronics made possible the speed and later the miniaturization that characterize modern computers.

British countess and mathematician Ada Lovelace is popularly credited as history's first programmer, as she was the first to express an algorithm intended for implementation on a computer, Charles Babbage's analytical engine, in October 1842, intended for the calculation of Bernoulli numbers.

As Doyle remarked to muse Joseph Bell, " Holmes is as inhuman as a Babbage's calculating machine and just about as likely to fall in love ".

Due to Lords Byron and Babbage's intervention, the Irish potato famine never occurred, and as a result there is no mention of agitation for Irish home rule or Irish independence.

However, Babbage's invention was not built, and it is uncertain whether later users were aware of Babbage's idea.

Around 1825, according to Charles Babbage's autobiography, he invented the thaumatrope, which was later commercially publicised by Dr. John Ayrton Paris ( to whom the invention is more usually attributed ).

She is also considered to have been the world's first computer programmer, having written the first algorithm intended to be processed by a machine -- Charles Babbage's analytical engine.

She is credited as being the first programmer, having assisted in realising the potential of Babbage's analytical engine.

Silicon carbide is also then used as protection against armor-piercing shells developed to hit tanks that start life as American tractors, which use diesel engines developed thanks to funding from Krupp, who inspired Bismarck's welfare scheme based on Quetelet's statistics that inspired the Charles Babbage's difference engine, whose punch cards were used to rivet the " SS Great Eastern ," the monster ship that laid the transatlantic cable insulated with gutta-percha used to manufacture golf balls for factory managers in industrial Scotland, where James Watt had a run-in with Cavendish, whose protegee was James Macie aka James Smithson, who caused all the row in the capitol building, so the money got used to set up a world-renowned institution named after James Macie's new family name, which was Smithson: The institution known as the Smithsonian.

It was first described in 1837 as the successor to Babbage's Difference Engine, a design for a mechanical computer.

Babbage's first attempt at a mechanical computing device, the Difference Engine, was a special-purpose calculator designed to tabulate logarithms and trigonometric functions by evaluating finite differences to create approximating polynomials.

This machine was built using materials and engineering tolerances that would have been available to Babbage, quelling the suggestion that Babbage's designs could not have been produced using the manufacturing technology of his time.

Despite this, Babbage's work fell into historical obscurity and the Analytical Engine was unknown to builders of electro-mechanical and electronic computing machines in the 1930s and 1940s when they began their work, resulting in the need to re-invent many of the architectural innovations Babbage had proposed.

* Moriarty by Modem, a short story by Jack Nimersheim, describes an alternate history where Babbage's Analytical Engine was indeed completed and had been deemed highly classified by the British government.

In 1991, a perfectly functioning difference engine was constructed from Babbage's original plans.

Babbage's father, Benjamin Babbage, was a banking partner of the Praeds who owned the Bitton Estate in Teignmouth.

Although Babbage's design was technically feasible, no one had built a mechanical device to such exacting standards before, so the engine proved to be much more expensive than anticipated.

Inspired by Babbage's difference engine plans, Per Georg Scheutz built several difference engines from 1855 onwards, one of which was sold to the British government in 1859.

This was to celebrate the 200th anniversary of Babbage's birth.

A machine based on Babbage's difference engine was built in 1843 by Per Georg Scheutz and his son Edward.

Its design was influenced by Babbage's Analytical Engine, using decimal arithmetic and storage wheels and rotary switches in addition to electromagnetic relays.

Her work never ran because Babbage's machine was never completed to a functioning standard in her time ; the first programmer to successfully run a program on a functioning modern electronically based computer was pioneer computer scientist Konrad Zuse, who achieved this feat in 1941.

Charles Babbage's analytical engine ( 1830s ) would have been the first Turing-complete machine if it had been built at the time it was designed.

It was not until the mid-19th century ( in Babbage's secret work during the Crimean War and Friedrich Kasiski's generally equivalent public disclosure some years later ), that cryptanalysis of well-implemented polyalphabetic ciphers got anywhere at all.

He was influential in publicising Charles Babbage's Difference engine.

Aiken was inspired by Charles Babbage's Difference Engine.

Ironically, perhaps the Association's most momentous influence on science was in 1878 when a committee of the Association recommended against constructing Charles Babbage's analytical engine.

Howard Aiken mentioned Babbage extensively when he convinced IBM to build the Harvard Mark I in 1937 ; when the machine was finished some hailed it as " Babbage's dream come true ".

Among the most complex were Babbage's difference and analytical engines, which were mechanical versions of computers.

Howard Aiken, who built the quickly-obsoleted electromechanical calculator, the Harvard Mark I, between 1937 and 1945, praised Babbage's work likely as a way of enhancing his own stature, but knew nothing of the Analytical Engine's architecture during the construction of the Mark I, and considered his visit to the constructed portion of the Analytical Engine " the greatest disappointment of my life ".

During the 1980s, Allan Bromley, an associate professor at the University of Sydney, Australia, studied Babbage's original drawings for the Difference and Analytical Engines at the Science Museum library in London.

Replacement of the hard-to-implement decimal system ( used in Charles Babbage's earlier design ) by the simpler binary system meant that Zuse's machines were easier to build and potentially more reliable, given the technologies available at that time.

While at Clement's workshop he helped with the manufacture of Charles Babbage's calculating machine, the Difference engine.

In 2005, Tim Robinson displayed his own Meccano differential analyser at the Computer History Museum, at Mountain View, California, USA, and Robinson has also built and exhibited two models of Charles Babbage's difference engine, also using Meccano.

In 1991, the London Science Museum built a complete and working specimen of Babbage's Difference Engine No. 2, a design that incorporated refinements Babbage discovered during the development of the Analytical Engine.

To supervise his collections Darwin had to return to London, and on Lyell's advice he planned to arrive on Friday 3 March 1837, in time for one of Charles Babbage's Saturday parties, talking shops about the latest developments " brilliantly attended by fashionable ladies, as well as literary and scientific gents " and " a good mixture of pretty women ", bankers and politicians, where Babbage promoted such projects as his mechanical computer.
