William Oughtred attended Eton School, which although a very famous school was in fact his local school. From there he went to King's College Cambridge, entering in 1592. Three years later he became a Fellow of King's College, received his B.A. in 1596 and his M.A. in the year 1600. It is surprising that although very little mathematics was taught at either Eton or Cambridge at this time Oughtred became passionately interested. He wrote:- ... the time which over and above those usuall studies I employed upon the mathematicall sciences I redeemed night by night from my naturall sleep, defrauding my body, and inuring it to watching, cold, and labour, while most others tooke their rest. Oughtred was ordained an Episcopal minister in 1603. In 1604 he became vicar of Shalford and later, in 1610, he became rector of Albury. Oughtred took private pupils who came to his house and lived there free of charge while they received mathematical instruction. He had many pupils but the most famous were John

And until well into the 20th century companies used this method for transmitting information. These perforated tapes, or punch tapes, will also be adopted for the output of computer. The teletype (telex) terminals accepted only this kind of tape and were the sole way to communicate with computers. Thus data the punched tape will be used for the decades to come in dataprocessing.

Sandboxes gave way to trays with lines and eventually grooved trays with balls. Grooved trays were introduced into China by the Han Dynasty period (206 B.C - 220 A.D.) During the Ming Dynasty (1368-1636) the rod abacus was developed. One source says the Egyptians developed rod and bead abacuses as early as 500 B.C.

Hands Hands were the first computers. Try it out by one hand to count from 1 to 10. For 1 to 5 you bend a finger and from 6 to 10 you straighten it.
On the other hand you keep count of the 10s. You bend a finger fro each ten from 10 to 50 and straighten a finger for 60 to one hundred. The example below shows a total of 87.

Use the right hand to count the 10s. If you start with the thumb this would represent 80. The abacus People first started to compute by using parts of their bodies. Fingers, toes, arms, wrists and even ears were used to keep count. The first real computing machine was the abacus, which was invented about 3000 BC by the Chinese and the Babylonians. The first mechanical computer In 1642, Blaise Pascal, the nineteen year old son of a government tax official, was working in his father's office and he was bored adding all the figures. To solve his problem he invented a calculating machine. This was a mechanical device that used a series of gears to produce the movement of the display that represented units, tens, hundreds and so on. Gottfried Leibniz developed an improved model that could add, subtract, multiply and divide. It was the first of the mechanical desk calculator.

Computing Machines Significant discoveries In 1642, Blaise Pascal, the nineteen year old son of a government tax official, working in his fatherís office, invented a calculating machine to relieve the boredom of adding figures. This was a mechanical device that used a series of gears to produce the relative movement of the display that represented units, tens, hundreds and so on. Gottfried Leibniz developed an improved model that could add, subtract, multiply and divide. It was the forerunner of the mechanical desk calculator. The first calculating machine In addition to broadening our mathematical knowledge and skill the other need was to increase the speed and accuracy of calculations involving many numbers. The first calculating machine, the abacus, appeared around 500 BC. Logarithms and the slide rule Also in the 17 th century, Scottish mathematician, John Napier, discovered the system of mathematics called logarithms that converted multiplication and division into addition and subtraction. A French army officer, Amedee Mannheim, designed the device known as the slide rule in 1850 that was based on Napierís logarithms. The slide rule was a hand held calculator for multiplying and dividing large numbers. The first computing machine A significant event in the history of computers was the attempts by Charles Babbage, a 19th century Englishman to develop a computing machine. Over a period of fifty years he designed two machines to automatically carry out complex calculations. The first machine, known as the Difference Engine, was never completed because the government withdrew its funding. The second machine, called the Analytical Engine, was designed to carry out even the most complex calculations but it was never built because Babbage lost interest when he became involved in other activities. Some claim the machines could not be built because the degree of precision required for the many components was not possible at that time. The machines would have involved over two tonnes of metal components. In the second half on the 20

Computermuseum: Rekenlat
Status: publiek Laatste wijziging: 15 oktober 1996
De Rekenlat
Werkingsprincipe
Rekenlatten bestaan in verscheidene vormen, types en afmetingen. Het klassieke type bestaat uit drie linialen, waarvan de onderste en de bovenste onwrikbaar met mekaar zijn verbonden, zodat de middelste liniaal er kan tussen bewegen. Over het geheel kan een loper (cursor) verschoven worden. Rekenlat voorzijde: Rekenlat achterzijde: Twee langs mekaar glijdende linialen met een identieke lineaire schaalverdeling laten toe twee getallen op te tellen en af te trekken. Indien de schaalverdeling logaritmisch is, kunnen op gelijkaardige wijze vermenigvuldigingen en delingen uitgevoerd worden, gebruik makend van de regel dat de logaritme van een produkt de som van de logaritmen is. Op dit principe is de werking van de rekenlat gebaseerd. Volgende figuur illustreert de vermenigvuldiging 2 x 3. De nauwkeurigheid is echter nogal beperkt. Met een rekenlat van 30 cm lengte kan een ervaren gebruiker drie juist beduidende cijfers aflezen, wat voor vele ingenieurstoepassingen voldoende is.
Geschiedenis
In 1620 voerde Edmund Gunter rekenkundige vermenigvuldigingen en delingen uit door met een passer afstanden op een logaritmische schaal op te tellen en af te trekken. Enkele jaren later verbeterde William Oughtred deze werkwijze door twee logaritmische schalen naast en ten opzichte van mekaar te verschuiven. Hij construeerde eveneens een cirkelvormige rekenlat, die nog handiger in gebruik was. Later zijn ook cilindervormige rekenlatten geconstrueerd. In 1850 werd door Amedee Mannheim de cursor of loper toegevoegd. Ook schaalverdelingen voor het berekenen van elementaire functies werden aangebracht.

Slide Rule and Abacus The slide rule is a mechanical device for making rapid mathematical calculations other than addition and subtraction. It can be used to multiply, divide, find powers and roots, and perform more complex operations involving logarithms and trigonometric functions. The history of the slide rule essentially began in 1614, when John Napier published his first table of logarithms, but the device in its present form was designed in 1850 by a French army officer, Amedee Mannheim. The invention of hand-held electronic calculators made the slide rule obsolete. Download from WebEE Excalibur - an RPN Calculator for Windows

THE ORIGIN
OF THE
AUTOMOBILE
When was the first automobile built? Daimler and Benz are traditionally credited with building the first cars in 1886, but the French claim it was first built in 1884 by Delamare-Deboutteville. Still others claim it was built in 1860. It all depends on your definition of a car. Contrary to popular belief, Henry Ford did not invent the automobile. He wasn't even close. What Ford did was perfect the assembly line technique, well after the turn of the century. This allowed him to lower the cost of the automobile drastically, bringing a rich man's plaything within reach of the masses, thereby changing Western society. Reason enough to be famous. In 1860 a Frenchman, Edouard Delamare-Debouteville, did some experiments and filed some patents for a self-propelled car. In 1884 France built the world's first car. However the first self-propelled automobile existed long before 1884. Charles Dietz and his sons ran steam-driven road tractors hauling passenger carriages on routes around Paris and Bordeaux prior to 1850. And in America, steam coaches were built in the 1860 to '80 period by Harrison Dyer of Boston, Joseph Dixon of Lynn, Mass., Rufus Porter of Hartford, Conn., and William T. James of New York City. Amedee Bollee Sr. was the most remarkable of the steam-car pioneers. Heir to a bell foundry at Le Mans, he added mechanical workshops and built a series of advanced-design vehicles from 1873 to 1883. There was nothing particularly new or refined in his steam power systems, but his sense of vehicle architecture was superb.

HISTORY-1: EARLY HISTORY OF COMPUTERS (PRE-1939) 3000 yrs ago The Chinese first used the Abacus for arithmetic. It's still used in many countries.
Scottish mathematician John Napier published his invention of the concept of the logarithm, having worked on it for 20 years. John Briggs, a professor of geometry at Oxford in England, published the first table of logarithms (to base 10) of numbers 1 to 1000. William Oughtred, an English mathematician, invented a slide rule (an analog device). Blaise Pascal, an extremely intelligent 19 year old French Mathematician, built the first mechanical computer, or adding machine. It could add and subtract numbers. The adding mechanism in this machine is still used in many present-day machines. Joseph Jacquard - he used punched cards to automate control of looms for weaving. Charles Babbage, a British mathematician, designed the forerunner of the modern computer, the Difference Engine/Analytical Engine. It was never built because engineers had not yet learned how to build precision instruments of this type (and political problems). mid 1800's Slide rule as we know it today invented by French artillery officer, Amedee Mannheim. Based on logarithms, it allowed a gunner to compute ballistic information more quickly.

http://www.rit.edu/~bpbsma/Slide Rule.htm
History of the Slide Rule Slide rules are based on logarithms so our history lesson must begin with Scottish mathematician and theologian John Napier who first described logarithms. Napier's discussion of logarithms appeared in Mirifici logarithmorum canonis descriptio in 1614. Two years later, an English translation of Napier's original Latin text was published, translated by Edward Wright. In the preface of the book Napier explains his thinking behind his great discovery, quoted from the English translation of 1616 of the original Latin. “Seeing there is nothing right well-beloved Students of the Mathematics that is so troublesome to mathematical practice, nor that doth more molest and hinder calculators, than the multiplications, divisions, square and cubical extractions of great numbers, which besides the tedious expense of time are for the most part subject to many slippery errors, I began therefore to consider in my mind by what certain and ready art I might remove those hindrances. And having thought upon many things to this purpose, I found at length some excellent brief rules to be treated of perhaps hereafter. But amongst all, none more profitable than this which together with the hard and tedious multiplications, divisions, and extractions of roots, doth also cast away from the work itself even the very numbers themselves that are to be multiplied, divided and resolved into roots, and putteth other numbers in their place which perform as much as they can do, only by addition and subtraction, division by two or division by three.”
