Charles Babbage was born December 26, 1792 was a British mathematician who first put forward the idea of ​​a programmable computer. Most of the machinery developed can now be seen in the Science Museum London. In 1991, using Babbage's original plans, the differential engine developed and this machine can function perfectly, proving that Babbage's ideas on this machine can indeed 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). .: [Close] [Click 2x] [Close]:. At that time, calculations using mathematical tables often have errors. Babbage wanted to develop a way of doing calculations mechanically, so as to reduce the calculation error is often done by humans. At that time, Babbage was inspired by the development of calculating machines carried out by Wilhelm Schickard, Blaise Pascal, and Gottfried Leibniz. Preliminary ideas about Babbage engine 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" ("note on the application of machinery to the computation 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 full century before the development of large-scale electronic calculating machines occurs. Machine that he designed, which gave the name "analytical engine" in principle capable of carrying out what can be done modern calculator (though not as fast, because the "engine analyst" is not designed for electric powered). Unfortunately, since the 19th century technology is not yet advanced enough, Babbage was not able to complete the construction "analysts machine" that, besides it can not require a huge time and cost. After his death, his ideas were so brilliant almost forgotten. In 1937, Babbage writing to the attention of Howard H. Aiken, graduate degree from Harvard. Aiken is also trying to complete the design of computer machines, moved by the idea of ​​Babbage. In cooperation with IBM, Aiken could make Mark I, the first computer for all purposes. Two years after Mark I operated (1946), a group of engineers and other inventors completed the ENIAC, the first electronic calculating machine. Since then, advances in computer technology is growing rapidly. Calculating machines had so much influence in the world, it would only become more important in the future, their contributions to the development of the Babbage computer Aiken is not greater than or than John Mauchly and JO Eckert (the main character in the design of the ENIAC). On the basis that there are at least three predecessor Babbage (Blaise Pascal, Gottfried Leibniz and Joseph Marie Jacquard) has made a donation equivalent to Babbage. Pascal, a mathematician, philosopher and French scientists discovered the sum of mechanical machines in 1642. In 1671 Gottfired Wilhelm von Leibniz, a philosopher and a mathematician to design a machine that could add, subtract, multiply and divide. Leibniz was also the first to demonstrate the importance of "binary system," the system is the sum of the two "digits" that in modern times it is widely used in the computer machine. And the other French, Jacquard, who in the early 19th century has been using computers to monitor charging system looms. Jacquard loom which sells heavy commercial, had a major influence on the thinking of Babbage. May affect also Herman Hollerith, an American who at the end of the 19th century using computer charging system to create a column of data in the Census Bureau. - 5234
