| + | ====== The Analytical Engine ====== | ||
| + | |||
| + | This section contains notes about a mechanical computer that Charles Babbage intended to be able to calculate any analytical function. The most detailled single description is found in the publication by L.F. Menabrea, published in 1842, and translated by Lady Ada Augusta Lovelace from the French original, significantly extended by appendices //Note A// to //Note G//. A facsimile scan is available at [[https:// | ||
