A collaboration started which resulted in the publication of the book, Japanese Temple Geometry Problems by the Charles Babbage Research Centre in Canada.

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.

In 1823, the British government gave Babbage ₤ 1700 to start work on the project.

Babbage was a difficult man to work with and argued with everyone.

Following Babbage, although unaware of his earlier work, was Percy Ludgate, an accountant from Dublin, Ireland.

Charles Babbage was known to have broken a variant of the cipher as early as 1854 ; however, he didn't publish his work.

The work of Pierre Jaquet-Droz predates that of Charles Babbage by decades.

He was deeply sceptical of the work of Charles Babbage and of his ability to deliver a working Difference Engine or Analytical Engine.

* Oral history interview with Harry M. Markowitz, Charles Babbage Institute, University of Minnesota-Markowitz discusses his development of portfolio theory, sparse matrices, and his work at the RAND Corporation and elsewhere on simulation software development ( including computer language SIMSCRIPT ), modeling, and operations research.

The recognised excellence of Clement's machine tools and his skill in precision engineering led to him being employed by Charles Babbage in 1823 to work on his project to design and build his mechanical calculating device, the difference engine.

The high prices of his large precision tools led to a falling out with Babbage ( at the time workmen were allowed to keep any tools made by them in the course of their work ), but his skill and the quality of his products kept him in employment for many years.

He was interested in astronomy, being a Fellow of the Royal Astronomical Society, and in computers, as is shown by a letter of his to Charles Babbage, dated March 23, 1836, among the Babbage manuscripts at the British Library, returning some logarithm tables that he had borrowed and adding " How happy I shall be when I can see such a work verified and enlarged by your divine machine ".

The comic is based on thorough research on the biographies and correspondence between Babbage and Lovelace, which is then twisted for humorous effect.

* Georgia on My Mind is a novelette by Charles Sheffield which involves two major themes: being widowed and the quest for a legendary Babbage computer.

Ada Lovelace reported in her notes on the Analytical Engine: " Mr. Babbage believes he can, by his engine, form the product of two numbers, each containing twenty figures, in three minutes ".

The parish register of St. Mary's Newington, London, shows that Babbage was baptised on 6 January 1792, supporting a birth year of 1791.

In 1822, Charles Babbage proposed the use of such a machine in a paper to the Royal Astronomical Society on 14 June entitled " Note on the application of machinery to the computation of astronomical and mathematical tables ".

The other issue that undermined the government ’ s confidence in the difference engine was Babbage had moved on to an analytical engine.

Babbage went on to design his much more general analytical engine, but later produced an improved " Difference Engine No. 2 " design, between 1847 and 1849.

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.

Mary Boole claimed profound influence ( via her uncle George Everest ) of Indian thought on Boole, as well as Augustus De Morgan and Charles Babbage:

Think what must have been the effect of the intense Hinduizing of three such men as Babbage, De Morgan, and George Boole on the mathematical atmosphere of 1830-1865.

Since 1824, Indian logic attracted the attention of many Western scholars, and has had an influence on important 19th-century logicians such as Charles Babbage, Augustus De Morgan, and particularly George Boole, as confirmed by his wife Mary Everest Boole who wrote in an " open letter to Dr Bose " titled " Indian Thought and Western Science in the Nineteenth Century " written in 1901 < ref >

Sabine's appointment was violently attacked by Charles Babbage, the father of the computer, ( largely on account of his associations with the Royal Society, whose scientific credentials Babbage did not recognise ) in a pamphlet entitled Reflections on the Decline of Science in England, and on Some of its Causes.

Babbage was able to take advantage of ideas developed for the analytical engine to make the new difference engine calculate more quickly while using fewer parts.

In 1837, Babbage described his 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 ).

* 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.

In 1842, the Italian mathematician Luigi Menabrea, whom Babbage had met while travelling in Italy, wrote a description of the engine in French.

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

Nine years later, the Science Museum completed the printer Babbage had designed for the difference engine.

By the time the government killed the project in 1842, they had given Babbage over ₤ 17, 000, more than double the cost of a warship, without receiving a working engine.

What Babbage did not, or was unwilling to, recognize was that the government was interested in economically produced tables, not the engine itself.

By developing something better, Babbage had rendered the difference engine useless in the eyes of the government.

In 2000, the printer which Babbage originally designed for the difference engine was also completed.

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