OAS_AD('Top'); SURREY PEOPLE WILLIAM OUGHTRED 1574 - 1660 William Oughtred sleeps where he died, the last fifty years of his life was spent as the parson at Albury. He was born at Eton in 1574 and he went from the college there to Cambridge where it was discovered that he was a genius for mathematics. While an undergraduate there he wrote his Easy Method of Mathematical Dialling, which was translated into Latin by Sir Christopher Wren, who was at the time at Oxford. Oughtred was ordained in the the church in 1603 and came to Albury from Shalford in 1610 where he married and attended to his parish, and also spent time working away at his problem with an ink-horn fixed to his bed head and a tinderbox and candle by his side, ready to record a solution of his difficulties. Night after night would be spent working out a problem, and his most famous work embodied practically all that was known of algebra and arithmetic, and included Oughtred's invention, the X for multiplication, and the

A contemporary of Oughtred's, Edmund Gunter, devised a logarithmic rule in 1620, which could be used to multiply and divide using a pair of calipers. Oughtred was the first to see that a simpler and more sophisticated method of multiplication and division could be achieved by placing two logarithmic rules side by side and using the position of the numbers relative to each other to calculate the desired results. He also developed the circular slide rule, which operated in the same fashion as a linear slide rule, except that it makes use of an inner and an outer ring click here to make a comment Show All 24-Apr-2004 mail this page Pagenation

He also introduced the "x" symbol for multiplication , as well as the abbreviations "sin" for sine and "cos" for cosine. Oughtred was born at Eton , and educated there and at King's College, Cambridge , of which he became fellow. Being admitted to holy orders, he left the university about 1603, and was presented to the rectory of Aldbury, near Guildford in Surrey ; and about 1628 he was appointed by the earl of Arundel to instruct his son in mathematics. He corresponded with some of the most eminent scholars of his time on mathematical subjects; and his house was generally full of pupils from all quarters. It is said that he expired in a sudden transport of joy upon hearing the news of the vote at Westminster for the restoration of Charles II He published, among other mathematical works, Clavis Mathematicae (The Key to Mathematics), in 1631; a treatise on

To subscribe click here ; to read past issues click here March 5 Today we celebrate the slide rule and its inventor. On March 5, 1574, William Oughtred (pronounced AW-tred) was born in England. He was educated at Eton and Cambridge, and although he was a minister by profession, he spent nearly all his free time studying and teaching mathematics. In college, he became a workaholic who stayed awake late into the night studying math a habit he retained his entire life. Oughtred's contributions to mathematics were substantial. In his most famous book, Clavis Mathematicae (The Keys to Mathematics), he introduced several new mathematical symbols, such as the "x" for multiplication. In the 1620s or early 1630s, Oughtred invented the "slide rule" a device that lets users perform difficult calculations without consulting tables, by carefully sliding two specially-marked rulers against one another. Oughtred's original slide rule was actually round, made of rings which he called "circles of proportion," but it was not long before slide rules were made straight and much more convenient. The slide rule became the proud badge and status symbol of the mathematician, the scientist and the engineer. It was an utterly indispensable tool for more than three centuries, until it was supplanted in 1971 by the pocket calculator. Many of the men and women who were trained to use slide rules still treasure their retired tools as fond reminders of a bygone subculture, and of a different way of thinking.

Earliest Uses of Symbols for Trigonometric and Hyperbolic Functions Last revision: June 27, 1999 Sine. In 1583, Thomas Fincke (or Finck) (1561-1656) used sin. (with a period) in Book 14 of his Geometria rotundi. Cajori writes that "perhaps the first use of abbreviations for the trigonometric lines goes back to ... Finck" (Cajori vol. 2, page 150). In 1624, Edmund Gunter (1581-1626) used sin (without a period) in a drawing representing Gunter's scale (Cajori vol. 2, page 156). In 1632, William Oughtred (1574-1660) used sin (without a period) in Addition vnto the Vse of the Instrvment called the Circles of Proportion (Cajori vol. 1, page 193, and vol. 2, page 158). According to the trigonometry article at the University of St. Andrews website, the first use of sin in a book (thus disallowing Gunter's use) was in 1634 by H?rigone. However, the use by Oughtred would seem to predate that of H?rigone. Cosine. In his Geometria rotundi (1588) Thomas Fincke used sin. com. for the cosine. In 1674, Sir Jonas Moore (1617-1679) used Cos. in Mathematical Compendium (Cajori vol. 2, page 163).

Símbolos matemáticos Fecha de primera versión: 01-03-98 Fecha de última actualización: 21-07-98 Si alguien os pregunta quién utilizó por primera vez un símbolo matemático y no lo sabéis y tenéis que contestar, responded Euler , es muy probable que acertéis. Símbolos de relación: Antiguamente se utilizaban palabras para referirse a los símbolos, por ejemplo para el signo igual se utilizaba aequales, aequantur, o abreviaturas como aeq. El símbolo = aparece por primera vez en The Whetstone of whitte (El aguzador del ingenio) publicada en 1557 por Robert Recorde, que es el primer tratado inglés de álgebra. El autor afirma que eligió ese símbolo porque dos cosas no pueden ser más iguales que dos rectas paralelas. Este símbolo se generalizó hacia finales del siglo XVII; todavía en este siglo Descartes utiliza un signo semejante al símbolo del infinito, probable corrupción de la inicial de la palabra ae qualis (igual en latín).
