The historical difficulty in producing error free tables by teams of mathematicians and human " computers " spurred Charles Babbage's desire to build a mechanism to automate the process.

In a review of Charles Babbage's book Decline of Science in England in John Murray's Quarterly Review, he suggested the creation of " an association of our nobility, clergy, gentry and philosophers ".

However, up to the 1940s, many subsequent designs ( including Charles Babbage's machines of the 1822 and even ENIAC of 1945 ) were based on the decimal system ; ENIAC's ring counters emulated the operation of the digit wheels of a mechanical adding machine.

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.

* In common with many other complex mechanical devices, Charles Babbage's analytical engine used banks of cams to control each operation, i. e. it had a read-only control store.

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.

1822: Charles Babbage | Babbage's Difference engine.

* Ada Lovelace translates and expands Menabrea's notes on Charles Babbage's analytical engine, including an algorithm for calculating a sequence of Bernoulli numbers, regarded as the world's first computer program.

June 14: Charles Babbage | Babbage's Difference engine.

The concept that software might contain errors dates back to Ada Lovelace's 1843 notes on the analytical engine in which she speaks of the difficulty of preparing program " cards " for Charles Babbage's Analytical engine:

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.

The Science Museum now holds a collection of over 300, 000 items, including such famous items as Stephenson's Rocket, Puffing Billy ( the oldest surviving steam locomotive ), the first jet engine, a reconstruction of Francis Crick and James Watson's model of DNA, some of the earliest remaining steam engines, a working example of Charles Babbage's Difference engine ( and the latter, preserved half brain ), the first prototype of the 10, 000-year Clock of the Long Now, and documentation of the first typewriter.

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

Exhibitions included such large pieces of machinery as parts of Charles Babbage's analytical engine, cotton mills, and maritime engines by the firm of Henry Maudslay, as well as a range of smaller goods including fabrics, rugs, sculptures, furniture, plates, silver and glass wares, and wallpaper.

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.

* Ada Lovelace translates and expands Menabrea ’ s notes on Charles Babbage's analytical engine, including an algorithm for calculating a sequence of Bernoulli numbers, regarded as the world's first computer program.

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 ).

Examples of the latter include Charles Babbage's Crimean War era work on mathematical cryptanalysis of polyalphabetic ciphers, redeveloped and published somewhat later by the Prussian Friedrich Kasiski.

The first design for a program-controlled computer was Charles Babbage's Analytical Engine in the 1830s.

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.

During a nine-month period in 1842-1843, Ada Lovelace translated the memoir of Italian mathematician Luigi Menabrea about Charles Babbage's newest proposed machine, the Analytical Engine.

* Charles Babbage begins the conceptual design of an " analytical engine ", a mechanical forerunner of the modern computer.

Charles Babbage owned one of these portraits ; it inspired him in using perforated cards in his analytical engine.

As chemistry journals emerged throughout the 1820s and 1830s, Charles Babbage developed his " difference engine ," the first step towards the modern computer, in 1822 and his " analytical engine ” by 1834.

It posits a Victorian Britain in which great technological and social change has occurred after entrepreneurial inventor Charles Babbage succeeded in his ambition to build a mechanical computer ( actually his analytical engine rather than the difference engine ).

From the start Henry Charles Lea was encouraged to master far more difficult lessons than were commonly expected for a boy his age ; he had a ready facility for languages and analytical thought.

* Charles Babbage begins the conceptual design of an " analytical engine ", a mechanical forerunner of the modern computer.

Woodhouse did not exercise much influence on the majority of his contemporaries, and the movement might have died away for the time being if it had not been for the advocacy of George Peacock, Charles Babbage, and John Herschel, who formed the Analytical Society, with the object of advocating the general use in the university of analytical methods and of the differential notation.

In Passages from the Life of a Philosopher, Charles Babbage wrote that MacCullagh was " an excellent friend of mine " and discussed the benefits and drawbacks of the analytical engine with him.

The world's first computer printer was a 19th century mechanically driven apparatus invented by Charles Babbage for his difference engine.

In 1833, Charles Babbage moved on from developing his difference engine ( for navigational calculations ) to a general purpose design, the Analytical Engine, which drew directly on Jacquard's punched cards for its program storage.

* 1822 – Charles Babbage proposes a difference engine in a paper to the Royal Astronomical Society entitled " Note on the application of machinery to the computation of astronomical and mathematical tables ".

Specifically, Charles Babbage planned to use cards to store programs in his Analytical engine.

Balzer's rotary engine was later converted to static radial operation by Langley's assistant, Charles M. Manly, creating the notable Manly-Balzer engine.

Another motorcycle with a rotary engine was Charles Redrup's 1912 Redrup Radial, which was a three-cylinder 303 cc rotary engine fitted to a number of motorcycles by Redrup.

* 1899: Charles Gordon Curtis patented the first gas turbine engine in the USA (" Apparatus for generating mechanical power ", Patent No. US635, 919 ).

Through a series of episodic events — some friends try to involve Stan in a criminal plot, a white woman propositions Stan in a store, Stan and his friend Bracy ( Charles Bracy ) attempt to buy a car engine — a mosaic of an austere working-class life emerges in which Stan feels unable to affect the course of his life.

She intended to fly to Paris in her single engine Lockheed Vega 5B to emulate Charles Lindbergh's solo flight.
