Analytical Engine Quotes (5 quotes)

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. Supposing for instance, that the fundamental relations of pitched sounds in the science of harmony and of musical composition were susceptible of such expression and adaptations, the engine might compose elaborate and scientific pieces of music of any degree of complexity or extent.
In Richard Taylor (ed.), 'Translator’s Notes to M. Menabrea’s Memoir', Scientific Memoirs, Selected from the Transactions of Foreign Academies and Learned Societies and from Foreign Journals (1843), 3, Note A, 694. Her notes were appended to L.F. Menabrea, of Turin, Officer of the Military Engineers, 'Article XXIX: Sketch of the Analytical Engine invented by Charles Babbage Esq.', Bibliothèque Universelle de Gnve (Oct 1842), No. 82.

I want to put in something about Bernoulli’s numbers, in one of my Notes, as an example of how the implicit function may be worked out by the engine, without having been worked out by human head & hands first. Give me the necessary data & formulae.
Lovelace Papers, Bodleian Library, Oxford University, 42, folio 12 (6 Feb 1841). As quoted and cited in Dorothy Stein (ed.), 'This First Child of Mine', Ada: A Life and a Legacy (1985), 106-107.

The Analytical Engine weaves algebraical patterns just as the Jacquard loom weaves flowers and leaves.
[Describing Charles Babbage's machine.]
In her notes as translator, following her translation of I. F. Menabrea, 'Sketch of the Analytical Engine Invented by Charles Babbage, Esq.', (from Bibliothègue Universelle de Génève (Oct 1842), No. 82) in Richard Taylor (ed.), Scientific Memoirs (1843), 3, 696.

The Analytical Engine has no pretensions whatever to originate anything. It can do whatever we know how to order it to perform. It can follow analysis; but it has no power of anticipating any analytical relations or truths. Its province is to assist us to making available what we are already acquainted with.
[Describing Charles Babbage's machine.]
In her notes as translator, following her translation of I. F. Menabrea, 'Sketch of the Analytical Engine Invented by Charles Babbage, Esq.', (from Bibliothègue Universelle de Génève (Oct 1842), No. 82) in Richard Taylor (ed.), Scientific Memoirs (1843), 3, 722.

The whole of the developments and operations of analysis are now capable of being executed by machinery ... As soon as an Analytical Engine exists, it will necessarily guide the future course of science.
Passages From the Life of a Philosopher (1864), 136-137.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
