Note G

Common card · No. 250863

Note G is a computer algorithm traditionally attributed to Ada Lovelace that was designed to calculate Bernoulli numbers using the hypothetical analytical engine designed by Charles Babbage. The algorithm was the last note in a series labelled "A" to "G", which were employed as visual aids to accompany Lovelace's English translation of Luigi Menabrea's 1842 French transcription of Charles Babbage's only lecture on the analytical engine. Her translation, along with her substantial notes on the possibilities of the analytical engine, were published in 1843. In Babbage's 1864 memoir he discusses the creation of the various notes with Lovelace, including note "G". He provided the mathematical formulas for the calculation of the Bernoulli numbers, which Ada converted into a step-by-step table of instructions for the analytical engine; she also spotted a bug for him: We discussed together the various illustrations that might be introduced: I suggested several, but the selection was entirely...
