One major improvement over Charles Babbage's non-functional device is the use of Leibniz's binary system (Babbage and others unsuccessfully tried to build decimal programmable computers). Zuse's machine also featured floating-point numbers with a 7-bit exponent, 14-bit mantissa (with a '1' bit automatically prefixed unless the number is 0), and ...
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.
1837: Charles Babbage proposes a design for the construction of a Turing complete, general purpose Computer, to be called the Analytical Engine. 1838: Matthias Schleiden: all plants are made of cells. 1838: Friedrich Bessel: first successful measure of stellar parallax (to star 61 Cygni). 1842: Christian Doppler: Doppler effect.
Charles Babbage began to construct a small difference engine in c. 1819 [4] and had completed it by 1822 (Difference Engine 0). [5] He announced his invention on 14 June 1822, in a paper to the Royal Astronomical Society, entitled "Note on the application of machinery to the computation of astronomical and mathematical tables".

Charles Babbage in 1843 and Percy Ludgate in 1909 designed the first two Analytical Engines in history. Ludgate's engine used multiplication as its basis (using his own discrete Irish logarithms ), had the first multiplier-accumulator (MAC), was first to exploit a MAC to perform division, stored numbers as displacements of rods in shuttles, and ...
