The London Science Museum's difference engine, the first one actually built from Babbage's design. The design has the same precision on all columns, but in calculating polynomials, the precision on the higher-order columns could be lower. A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions.
The analytical engine was a proposed digital mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. [2] [3] It was first described in 1837 as the successor to Babbage's Difference Engine, which was a design for a simpler mechanical calculator. [4]

The 19th century also saw the designs of Charles Babbage calculating machines, first with his difference engine, started in 1822, which was the first automatic calculator since it continuously used the results of the previous operation for the next one, and second with his analytical engine, which was the first programmable calculator, using ...

At the time Martin wrote the book, "mechanical calculating machines were a symbol of high-tech sophistication in the workplace"; reviewer Jonathan Samuel Golan suggests that it was aimed at collectors rather than historians, [5] while the editors of the Bulletin of Science, Technology & Society suggest that instead its purpose was to inform the public.
