This important work is the oldest surviving linguistic book and introduced the idea of metarules, transformations, and recursions, all of which have important applications in computer science.The first true computers were made with intricate gear systems by the Greeks. In this work he created 3,959 rules of grammar for Indias Sanskrit language.
Card Games 10.3 Operating System Mac OS SystemThe Inca had several of these computers and used them for tax and government records. Knots in the ropes served the purpose of binary digits. It is likely that the Antikythera mechanism was based on an astrological computer created by Archimedes of Syracuse in the 3rd century B.C.E.The first digital computers were made by the Inca using ropes and pulleys. The Antikythera mechanism could accurately predict eclipses and could draw up accurate astrological charts for important leaders. The system of gears added and subtracted angular velocities to compute differentials. The Antikythera mechanism used a system of 37 gears to compute the positions of the sun and the moon through the zodiac on the Egyptian calendar, and possibly also the fixed stars and five planets known in antiquity (Mercury, Venus, Mars, Jupiter, and Saturn) for any time in the future or past. In 1933 Babbage started work on his Analytical Engine, a mechanical computer with all of the elements of a modern computer, including control, arithmetic, and memory, but the technology of the day couldnt produce gears with enough precision or reliability to make his computer possible. The first computer programmer was Lady Ada, for whom the Ada programming language is named.In 1822 Charles Babbage proposed a difference engine for automated calculating. These cards were very similiar to the famous Hollerinth cards developed later. Created by Charles Babbage, these early computers used Punch cards as data storage (the cards contained the control codes for the various patterns). Spanish soldiers acting on orders of Roman Catholic priests destroyed all but one of the Inca computers in the mistaken belief that any device that could give accurate information about distant conditions must be a divination device powered by the Christian ∽evil (and many modern Luddites continue to view computers as Satanically possessed devices).In the 1800s, the first computers were programmable devices for controlling the weaving machines in the factories of the Industrial Revolution. Mac emulator online os xBut the real future of computing was digital rather than analog. Some of the most successful early computers were analog computers, capable of performing advanced calculus problems rather quickly. This branch of mathematics was essential for creating the complex circuits in modern electronic digital computers.In the 1900s, researchers started experimenting with both analog and digital computers using vacuum tubes. Lady Ada Lovelace wrote a program for the Analytical Engine that would have correctly calculated a sequence of Bernoulli numbers, but was never able to test her program because the machine wasnt built.George Boole introduced what is now called Boolean algebra in 1854. Babbage designed the Difference Engine No.2. See below for information on Von Neumanns important contributions.The first solid-state (or transistor) computer was the TRADIC, built at Bell Laboratories in 1954. Telephone and telegraph companies had been using reed relays for the logic circuits needed for large scale switching networks.The first modern electronic computer was the ENIAC in 1946, using 18,000 vacuum tubes. The Mark I was primarily mechanical, while the Mark II was primarily based on reed relays. In 1944 Howard Aiken of Harvard University created the Harvard Mark I and Mark II. Previous computers had their programming hard wired into the computer. This design is called von Neumann architecture and has been used in almost every digital computer ever made.Von Neumann architecture introduced flexibility to computers. When evaluating code, the binary numbers are decoded by some kind of physical logic circuits (later other methods, such as microprogramming, were introduced), and then the instructions are run in hardware. The computer knows the difference between code and data by which it is attempting to access at any given moment. Von Neumann architectureJohn Louis von Neumann, mathematician (born János von Neumann 28 December 1903 in Budapest, Hungary, died 8 February 1957 in Washington, D.C.), proposed the stored program concept while professor of mathemtics (one of the orginal six) at Princeton Universitys Institute for Advanced Services, in which programs (code) are stored in the same memory as data. Some researchers are now experimenting with Harvard architecture to solve the von Neumann bottleneck. Well designed data and code caches help, but only when the requested access is already loaded into cache. With data and code both being accessed over the same circuit lines, the processor has to wait for one while the other is being fetched (or written). Von Neumann was exposed to the concepts of logical design and universal machine proposed in Turings 1934 paper On Computable Numbers with an Application to the Entschiedungs-problem.Von Neumann worked with such early computers as the Harvard Mark I, ENIAC, EDVAC, and his own IAS computer.Early research into computers involved doing the computations to create tables, especially artillery firing tables. Morganstern recommended that he not ask questions, but just answer them.Von Neumann occassionally worked with Alan Turing in 1936 through 1938 when Turing was a graduate student at Princeton. Morganstern asked if they had any questions, and Gödel replied that he had no questions, but had found some logical inconsistencies in the Constitution that he wanted to ask the Immigration officers about. Constitution and American history while driving them to their immigration interview. There is a story that Oskar Morganstern coached von Neumann and Kurt Gödel on the U.S.
