Charles Babbage

Charles Babbage was born December 26, 1792 was a British mathematician who first proposed the idea of ​​a programmable computer. Much of the developed engine can now be seen at London's Science Museum. In 1991, using Babbage's original plans, a machine developed differential and the engine can function perfectly, which proves that the idea of ​​Babbage's machine can be implemented. Charles Babbage died October 18, 1871 at the age of 79 years, leaving children; Benjamin Herschel Babbage (1815), Charles Whitmore Babbage (1817), Georgiana Whitmore Babbage (1818), Edward Stewart Babbage (1819), Francis Moore Babbage (1821), Dugald Bromheald Babbage (1823), Henry Prevost Babbage (1824), Alexander Forbes Babbage (1827), Timothy grant Babbage (1829) At the time, calculations using mathematical tables often have errors. Babbage wanted to develop a way of performing calculations mechanically, so as to reduce the calculation error is often done by humans. At the time, Babbage was inspired by the development of calculating machines carried out by Wilhelm Schickard, Blaise Pascal, and Gottfried Leibniz. The initial idea of ​​Babbage engines are written in the form of a letter he wrote to the Royal Astronomical Society entitled "Note on the application of machinery to the computation of astronomical and mathematical tables" ("notes regarding the application of machinery to the calculation of astronomical and mathematical tables") dated June 14, 1822 . Computer history begins when British inventor Charles Babbage completed the general principles of the use of digital computers a full century before the development of large-scale electronic calculating machine going. Machines he designed, which gave the name "analytical engine" in principle capable of carrying out what can be done modern calculator (although not as fast, because the "machinery analyst" is not designed for electric-powered). Unfortunately, since the 19th century technology is not yet sufficiently advanced, could not complete the construction of Babbage's machine "analyst" is, but it can not require a huge time and cost. After his death, his ideas are so brilliant was almost forgotten. By 1937, Babbage writing to the attention of Howard H. Aiken, the Harvard graduate degree. Aiken is also trying to complete the design of computer machinery, moved by the idea of ​​Babbage. In cooperation with IBM, Aiken able to make the Mark I, the first computer for all purposes. Two years after the Mark I operated (1946), a group of engineers and other inventors completed the ENIAC, the first electronic calculator. Since then, advances in computer technology is growing rapidly. Calculating machines have so much influence in the world, would become even more important in the future, their contributions to the development of computer Babbage is not greater than or than John Mauchly Aiken and JO Eckert (Figure figure Scientists Inventors - http://www.tokoh-ilmuwan-penemu.com principal in the design of the ENIAC). On that basis there are at least three predecessors Babbage (Blaise Pascal, Gottfried Leibniz, and Joseph Marie Jacquard) have made a donation equivalent to Babbage. Pascal, a mathematician, philosopher and French scientists discovered the sum of mechanical machines in 1642. In 1671 Wilhelm von Leibniz Gottfired, a philosopher and mathematician to design a machine that can add, subtract, multiply and divide. Leibniz is also the first to demonstrate the importance of "binary system," namely the sum of the two "digits" in the modern era that is widely used in computer machinery. And other French people, Jacquard, who at the beginning of the 19th century have been using computers to monitor the charging system looms. Jacquard looms are sold commercially profusely, had a major influence on the thinking of Babbage. May be affected also Herman Hollerith, an American who in the late 19th century using a computer charging system to make columns of data in the Census Bureau.
