History of Computing Prehistory – the World Before 1946
Social and Professional Issues in IT Prehistory - the world before 1946 History of Computing Prehistory – the world before 1946 The word “Computing” Originally, the word computing was synonymous with counting and calculating, and a computer was a person who computes. Since the advent of the electronic computer, it has come to also mean the operation and usage of these machines, the electrical processes carried out within the computer hardware itself, and the theoretical concepts governing them. Prehistory: Computing related events 750 BC - 1799 A.D. 750 B.C. The abacus was first used by the Babylonians as an aid to simple arithmetic at sometime around this date. 1492 Leonardo da Vinci produced drawings of a device consisting of interlocking cog wheels which could be interpreted as a mechanical calculator capable of addition and subtraction. A working model inspired by this plan was built in 1968 but it remains controversial whether Leonardo really had a calculator in mind 1588 Logarithms are discovered by Joost Buerghi 1614 Scotsman John Napier invents an ingenious system of moveable rods (referred to as Napier's Rods or Napier's bones). These were based on logarithms and allowed the operator to multiply, divide and calculate square and cube roots by moving the rods around and placing them in specially constructed boards. 1622 William Oughtred developed slide rules based on John Napier's logarithms 1623 Wilhelm Schickard of Tübingen, Württemberg (now in Germany), built the first discrete automatic calculator, and thus essentially started the computer era. His device was called the "Calculating Clock". This mechanical machine was capable of adding and subtracting up to 6 digit numbers, and warned of an overflow by ringing a bell.

To obtain the 3D CAD (computer-aided design) model and the geometric documentation of said invention, CATIA V5 R20 software has been used. The starting materials for this research, mainly the plans of this arithmetic machine, are collected in the volumes Oeuvres de Blaise Pascal published in 1779. Sketches of said machine are found therein that lack scale, are not dimensioned and certain details are absent; that is, they were not drawn with precision in terms of their measurements and proportions, but they do provide qualitative information on the shape and mechanism of the machine. Thanks to the three-dimensional modelling carried out; it has been possible to explain in detail both its operation and the ﬁnal assembly of the invention, made from the assemblies of its different Citation: Rojas-Sola, J.I.; del subsets.

◆ INVENTORS AND INVENTIONS ◆ Eli Whitney THE COTTON GIN The first patent of major importance to be issued by the U.S. government after it was formed was Eli Whitney’s patent for the cotton gin (“gin” is short for “engine”), which was issued on March 14, 1794. The patent description is in longhand, for reasons I cannot explain. Upon graduating Yale as an engineer in 1792, Whitney, like many college graduates of today, found himself in debt and in need of a job. He left his home in Massachusetts and took a job as a teacher in South Carolina. That job fell through, and Katherine Greene, the war widow of General Nathanial Greene, invited Whitney to stay at her Georgia cotton plantation in early 1793. He noticed that long‐staple cotton, which was readily separated from its seed, could only be grown along the coast. The inland‐ grown variety of cotton had sticky green seeds that were difficult to cull from the fluffy white cotton bolls,COPYRIGHTED and thus was less profitable to MATERIALgrow and harvest. It took 10 hours of hand labor to sift out a single point of cotton lint from its seeds. Whitney, after observing the manual process being used for separating the sticky seeds from the cotton bolls, built his first machine, which did not work. The bulk cotton was pushed against a wire mesh screen, which held back the seeds while wooden Intellectual Property Law for Engineers, Scientists, and Entrepreneurs, Second Edition. Howard B.

Mechanical Calculator (Edited from Wikipedia)
Mechanical Calculator (Edited from Wikipedia) SUMMARY A mechanical calculator, or calculating machine, was a mechanical device used to automatically perform the basic operations of arithmetic. Most mechanical calculators were comparable in size to small desktop computers and have been rendered obsolete by the advent of the electronic calculator. Surviving notes from Wilhelm Schickard in 1623 report that he designed and had built the earliest of the modern attempts at mechanizing calculation. His machine was composed of two sets of technologies: first an abacus made of Napier's bones, to simplify multiplications and divisions. And for the mechanical part, it had a dialed pedometer to perform additions and subtractions. A study of the surviving notes shows a machine that would have jammed after a few entries on the same dial, and that it could be damaged if a carry had to be propagated over a few digits (like adding 1 to 999). Schickard abandoned his project in 1624 and never mentioned it again until his death eleven years later in 1635. Two decades after Schickard's failed attempt, in 1642, Blaise Pascal decisively solved these particular problems with his invention of the mechanical calculator. Helping his father as tax collector in France, Pascal designed the calculator to help in the large amount of tedious arithmetic required.; it was called Pascal's Calculator or Pascaline. Thomas' arithmometer, the first commercially successful machine, was manufactured two hundred years later in 1851; it was the first mechanical calculator strong enough and reliable enough to be used daily in an office environment. For forty years the arithmometer was the only type of mechanical calculator available for sale.

MACHINES to DO ARITHMETIC EARLY CALCULATORS the Term Computer Dates Back to the 1600S
ANChp0wTLV5_052002.qxp 5/20/02 10:53 AM Page 5 0.2 Part of the Picture The History of Computing # Four important concepts have shaped the history of computing: I the mechanization of arithmetic; I the stored program; I the graphical user interface; I the computer network. The following timeline of the history of computing shows some of the important events and devices that have implemented these concepts, especially the first two. Additional information about these and the other two important concepts follow the timeline. MACHINES TO DO ARITHMETIC EARLY CALCULATORS The term computer dates back to the 1600s. However, until the 1950s, the term referred almost exclusively to a human who performed computations. For human beings, the task of performing large amounts of computation is one that is laborious, time consuming, and error prone. Thus, the human desire to mechanize arithmetic is an ancient one. One of the earliest “personal calculators” was the abacus,with movable beads strung on rods to count and to do calculations. Although its exact origin is unknown, 3000 B.C. ABACUS the abacus was used by the Chinese perhaps 3000 to 4000 years ago and is still used today throughout Asia. Early mer- chants used the abacus in trading transactions. The ancient British stone monument Stonehenge,located near Salisbury, England, was built between 1900 and 1600 B.C. and, evidently, was used to predict the changes of the seasons. In the twelfth century, a Persian teacher of mathematics in Baghdad, Muhammad ibn-Musa al-Khowarizm, developed 1900-1600 B.C. STONEHENGE some of the first step-by-step procedures for doing computa- tions.

Gottfried Wilhelm Leibniz (1646 – 1716)
Gottfried Wilhelm Leibniz (1646 – 1716) From Wikipedia, the free encyclopedia, http://en.wikipedia.org/wiki/Gottfried_Leibniz Leibniz occupies a prominent place in the history of mathematics and the history of philosophy. He developed the infinitesimal calculus independently of Isaac Newton, and Leibniz's mathematical notation has been widely used ever since it was published. He became one of the most prolific inventors in the field of mechanical calculators. While working on adding automatic multiplication and division to Pascal's calculator, he was the first to describe a pinwheel calculator in 1685 and invented the Leibniz wheel, used in the arithmometer, the first mass-produced mechanical calculator. He also refined the binary number system, which is at the foundation of virtually all digital computers. In philosophy, Leibniz is mostly noted for his optimism, e.g., his conclusion that our Universe is, in a restricted sense, the best possible one that God could have created. Leibniz, along with René Descartes and Baruch Spinoza, was one of the three great 17th century advocates of rationalism. The work of Leibniz anticipated modern logic and analytic philosophy, but his philosophy also looks back to the scholastic tradition, in which conclusions are produced by applying reason to first principles or prior definitions rather than to empirical evidence. Leibniz made major contributions to physics and technology, and anticipated notions that surfaced much later in biology, medicine, geology, probability theory, psychology, linguistics, and information science. He wrote works on politics, law, ethics, theology, history, philosophy, and philology. Leibniz's contributions to this vast array of subjects were scattered in various learned journals, in tens of thousands of letters, and in unpublished manuscripts.

Writing and Calculating Passing on Knowledge
WRITING AND CALCULATING PASSING ON KNOWLEDGE We pass on information and knowledge constantly, in all aspects of life : in cooking, in education, in books, in music, on the street, in the countryside, at a lawyer’s office – the possibilities are endless. We are driven by the need for others to know something or to help them discover it. This desire is handed down from one generation to the next and shared with those around us. It can sometimes be spontaneous and unselfconscious, sometimes determined, systematic, institutionalized and ritualized. It can be found in our gestures, words and creative works. The act of passing on knowledge is free and unselfish, which is why monuments erected to commemorate tyrants and the commercialization of knowledge are tantamount to betrayal and distortion. It also builds bridges between very distant worlds, separated by time and space. The heroic films in 21st-century cinema are still rooted in myths dating back thousands of years. But not everything can be passed on. Personal details almost never survive. And customs and knowledge are lost when society, the economy and technology undergo significant change, when new ideas usurp old ones. The chosen pieces of art you see in these display cases are fragile. Papyrus, parchment, palm tree paper, photographs… are sensitive to light, temperature and humidity. The lighting with optical fibres produces a bright light whilst guaranteeing the lighting intensity supported by these type of works of art ( 50 lux ).

Merzbach .^•^.iitfCV SMI'lHSONl.iN INSTITUTION PRESS SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given sub stantive review.
