It seems that Ludgate worked as a clerk for an unknown corn merchant, in Dublin, and pursued his interest in calculating machines at night. [6] Charles Babbage in 1843 and Ludgate in 1909 designed the only two mechanical analytical engines before the electromechanical analytical engine of Leonardo Torres Quevedo of 1920 and its few successors, and the six first-generation electronic analytical ...
Note G, originally published in Sketch of The Analytical Engine Invented by Charles Babbage. Note G [a] is a computer algorithm written by Ada Lovelace that was designed to calculate Bernoulli numbers using the hypothetical analytical engine.
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.
Carl Wilhelm Scheele (German:, Swedish: [ˈɧêːlɛ]; 9 December 1742 – 21 May 1786 [2]) was a German Swedish [3] pharmaceutical chemist.. Scheele discovered oxygen (although Joseph Priestley published his findings first), and identified molybdenum, tungsten, barium, nitrogen, and chlorine, among others.
William John Macquorn Rankine FRSE FRS (/ ˈ r æ ŋ k ɪ n /; 5 July 1820 – 24 December 1872) was a Scottish mathematician and physicist.He was a founding contributor, with Rudolf Clausius and William Thomson (Lord Kelvin), to the science of thermodynamics, particularly focusing on its First Law.
William Murdoch was born in Bello Mill near Old Cumnock in Ayrshire, Scotland, the third of seven children and the first son to survive beyond infancy.A son of John Murdoch, a former Hanoverian artillery gunner and a Millwright and tenant of Bello Mill on the estate of James Boswell in Auchinleck, he was educated until the age of ten at the Old Cumnock Kirk School before attending Auchinleck ...
F W Lanchester's prototype petrol-electric car 1927, at Thinktank Birmingham Science Museum. Frederick William Lanchester (23 October 1868 – 8 March 1946), was an English polymath and engineer who made important contributions to automotive engineering and to aerodynamics, and co-invented the topic of operations research.
