The London Science Museum's difference engine, the first one built from Babbage's design. It has the same precision on all columns, except 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.
This prototype evolved into the "first difference engine". It remained unfinished and the finished portion is located at the Science Museum in London. This first difference engine would have been composed of around 25,000 parts, weighed fifteen short tons (13,600 kg), and would have been 8 ft (2.4 m) tall. Although Babbage received ample ...

Difference Engine, 1822 – Charles Babbage's mechanical device to calculate polynomials. Analytical Engine, 1837 – A later Charles Babbage device that could be said to encapsulate most of the elements of modern computers. Odhner Arithmometer, 1873 – W. T. Odhner's calculator who had millions of clones manufactured until the 1970s.
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.
