Home > Ada Byron's notes on the analytical engine

Babbage asked Ada Byron (also known as Ada Lovelace) to translate Menabrea's paper into English. He then further asked Lady Ada to augment the notes she had added to the translation, and she spent most of a year doing this.

These notes, which are more extensive than Menabrea's paper, were then published in The Ladies Diary and Taylor's Scientific Memoirs (under the pseudonym A.A.L.).

Her notes were labelled A, B, C, D, E, F and G, the last one being the longest.

In note G Ada describes an algorithm for the analytical engine to compute Bernoulli numbers. 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.

Note G could possibly also be said to be the first expression of the modern computer phrase " Garbage In, Garbage Out". Lovelace writes:

"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."

On the other hand, proponents of Artificial intelligence would dismiss the above quote as nonsense: Automated theorem provingProofs Automated theorem proving (the currently most important subfield of automated reasoning is the proving of mathematical theorems by a computer program. Depending on the underlying logic, the problem of deciding the validity of a theorem varies from could be cited as a counterexample.

There were indeed women in mid-century England who signed their names to mathematical articles in popular journals, and there were influential periodicals, such as the Edinburgh ReviewThe Edinburgh Review was one of the most influential magazines of the 19th century. It took for its motto "judex damnatur ubi nocens absolvitur" ("The judge is condemned when the guilty is acquitted. from Publilius Syrus. Started in 1802 by Francis Jeffre, that lent intellectual women psychological support.... Although the Ladies Diary ..., the most popular of the mathematical periodicals, encouraged women to join wit with beauty, it attracted serious amateurs of both sexes... [it] was a respectable place to pose mathematical problems and sustain debate... since there were few science periodicals in England until the 1830s, technical articles often appeared in general periodicals like the Ladies Diary. It may have been something similar that originally sparked Mrs. Somerville's interest in mathematics. At a tea party one afternoon, she recalled years later, young Mary Fairfax had been given a ladies' fashion magazine that contained a puzzle, the answer to which was given in strange symbols. These symbols turned out to be algebraAlgebra Algebra (from the Arabic al-jabr meaning reunion connection or completion is a branch of mathematics which may be roughly characterized as a generalization and extension of arithmetic; it also refers to a particular kind of abstract algebra struct. And that magazine became her introduction to the world of Euclidean geometryEuclidean geometry In mathematics, Euclidean geometry is the familiar kind of geometry on the plane or in three dimensions. Mathematicians sometimes use the term to encompass higher dimensional geometries with similar properties. Euclidean geometry someti and number.
