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 Science Museum has constructed two Difference Engines according to Babbage's plans for the Difference Engine No 2. One is owned by the museum. The other, owned by the technology multimillionaire Nathan Myhrvold, went on exhibition at the Computer History Museum [160] in Mountain View, California on 10 May 2008. [161]
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.

Babbage produced a prototype section of the Analytical Engine's mill and printer. [40] 1878 Spain: Ramón Verea, living in New York City, invented a calculator with an internal multiplication table; this was much faster than the shifting carriage, or other digital methods of the time. He wasn't interested in putting it into production, however ...
The Computer History Museum claims to house the largest and most significant collection of computing artifacts in the world. [a] This includes many rare or one-of-a-kind objects such as a Cray-1 supercomputer as well as a Cray-2, Cray-3, the Utah teapot, the 1969 Neiman Marcus Kitchen Computer, an Apple I, and an example of the first generation of Google's racks of custom-designed web servers.

He also commissioned the construction of a second complete Difference Engine #2 for himself, which was on display at the Computer History Museum in Mountain View, California, from May 10, 2008, to January 31, 2016, and currently resides in the Intellectual Ventures Laboratory.
Charles Babbage's Difference Engine in the Science Museum (London), built on a project led by Doron Swade. Doron Swade MBE, born 1944, is a museum curator and author, specialising in the history of computing. He is especially known for his work on the computer pioneer Charles Babbage and his Difference Engine. [1]
