William Jones (mathematician)
William Jones, FRS (16751 July 1749) was a Welsh mathematician best known for his use of the symbol (the Greek letter '' Pi'') to represent the ratio of the circumference of a circle to its diameter. He was a close friend of Sir Isaac Newton and Sir Edmund Halley. In November 1711, Jones became a fellow of the Royal Society, and later served as the Royal Society's vice-president. Early life William Jones was born as the son of Siôn Siôr (John George Jones) and Elizabeth Rowland in the parish of Llanfihangel Tre'r Beirdd, about west of Benllech on the Isle of Anglesey in Wales. He attended a charity school at Llanfechell, also on the Isle of Anglesey, where his mathematical talents were spotted by the local landowner Lord Bulkeley, who arranged for him to work in a merchant's counting-house in London. His main patrons were the Bulkeley family of north Wales, and later the Earl of Macclesfield. Early mathematical career Jones initially served at sea, teaching mathematics ...

Sir William Jones
Sir William Jones (28 September 1746 – 27 April 1794) was a British philologist, orientalist, Indologist and judge. Born in Westminster, London to Welsh mathematician William Jones, he moved to the Bengal Presidency where Jones served as a puisne judge on the Supreme Court of Judicature at Fort William and also became a scholar of ancient Indian history. As part of his research, he was the first to assert the kinship of the Indo-European languages. Jones also founded the Asiatic Society in Calcutta in 1784. Early life William Jones was born in London; his father William Jones (1675–1749) was a mathematician from Anglesey in Wales, noted for introducing the use of the symbol π. The young William Jones was a linguistic prodigy, who in addition to his native languages English and Welsh, learned Greek, Latin, Persian, Arabic, Hebrew and the basics of Chinese writing at an early age. By the end of his life, he knew eight languages with critical thoroughness. Jones's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Derivative
In mathematics, the derivative is a fundamental tool that quantifies the sensitivity to change of a function's output with respect to its input. The derivative of a function of a single variable at a chosen input value, when it exists, is the slope of the tangent line to the graph of the function at that point. The tangent line is the best linear approximation of the function near that input value. For this reason, the derivative is often described as the instantaneous rate of change, the ratio of the instantaneous change in the dependent variable to that of the independent variable. The process of finding a derivative is called differentiation. There are multiple different notations for differentiation. '' Leibniz notation'', named after Gottfried Wilhelm Leibniz, is represented as the ratio of two differentials, whereas ''prime notation'' is written by adding a prime mark. Higher order notations represent repeated differentiation, and they are usually denoted in Leib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Oughtred
William Oughtred (5 March 1574 – 30 June 1660), also Owtred, Uhtred, etc., was an English mathematician and Anglican clergyman.'Oughtred (William)', in P. Bayle, translated and revised by J.P. Bernard, T. Birch and J. Lockman, ''A General Dictionary, Historical and Critical'', (James Bettenham, for G. Strachan and J. Clarke, London 1734/1739), Vol. VIIIpp. 77-86(Google). After John Napier discovered logarithms and Edmund Gunter created the logarithmic scales (lines, or rules) upon which slide rules are based, Oughtred was the first to use two such scales sliding by one another to perform direct multiplication and division. He is credited with inventing the slide rule in about 1622. He also introduced the "×" symbol for multiplication and the abbreviations "sin" and "cos" for the sine and cosine functions. Clerical life Education The son of Benjamin Oughtred of Eton in Buckinghamshire (now part of Berkshire), William was born there on 5 March 1574/75 and was educated a ...

Infinite Series
In mathematics, a series is, roughly speaking, an addition of infinitely many terms, one after the other. The study of series is a major part of calculus and its generalization, mathematical analysis. Series are used in most areas of mathematics, even for studying finite structures in combinatorics through generating functions. The mathematical properties of infinite series make them widely applicable in other quantitative disciplines such as physics, computer science, statistics and finance. Among the Ancient Greeks, the idea that a potentially infinite summation could produce a finite result was considered paradoxical, most famously in Zeno's paradoxes. Nonetheless, infinite series were applied practically by Ancient Greek mathematicians including Archimedes, for instance in the quadrature of the parabola. The mathematical side of Zeno's paradoxes was resolved using the concept of a limit during the 17th century, especially through the early calculus of Isaac Newton. The ...

Differential Calculus
In mathematics, differential calculus is a subfield of calculus that studies the rates at which quantities change. It is one of the two traditional divisions of calculus, the other being integral calculus—the study of the area beneath a curve. The primary objects of study in differential calculus are the derivative of a Function (mathematics), function, related notions such as the Differential of a function, differential, and their applications. The derivative of a function at a chosen input value describes the Rate (mathematics)#Of_change, rate of change of the function near that input value. The process of finding a derivative is called differentiation. Geometrically, the derivative at a point is the slope of the tangent, tangent line to the graph of a function, graph of the function at that point, provided that the derivative exists and is defined at that point. For a real-valued function of a single real variable, the derivative of a function at a point generally determines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Philip Yorke, 1st Earl of Hardwicke, (1 December 16906 March 1764) was an England, English lawyer and politician who served as Lord High Chancellor of Great Britain. He was a close confidant of the Duke of Newcastle, Prime Minister between 1754 and 1756 and 1757 until 1762. Background A son of Philip Yorke, an lawyer, attorney, he was born at Dover. Through his mother, Elizabeth, daughter and co-heiress of Richard Gibbon of Rolvenden, Kent, he was connected with the family of Edward Gibbon the historian.

George Parker, 2nd Earl Of Macclesfield
George Parker, 2nd Earl of Macclesfield, FRS ( 17 March 1764) was a British politician and astronomer. Biography George was tutored by Welsh mathematician William Jones, who went on to become the first person to use the symbol (the Greek letter '' Pi'') to represent the ratio of the circumference of a circle to its diameter. Styled Viscount Parker from 1721 to 1732, he was Member of Parliament (MP) for Wallingford from 1722 to 1727, but his interests were not in politics. In 1722, he became a fellow of the Royal Society, and he spent most of his time in astronomical observations at his Oxfordshire seat, Shirburn Castle, which had been bought by his father in 1716; here he built an observatory and a chemical laboratory. He was very prominent in making the case in Parliament for the Calendar (New Style) Act 1750, with which the Kingdom of Great Britain and the British Empire changed from the Julian calendar to the Gregorian calendar in 1752.

Gareth Ffowc Roberts
Gareth (; Old French: ''Guerehet'', ''Guerrehet'', etc.) is a Knights of the Round Table">Knight of the Round Table in Arthurian legend. He is the youngest son of King Lot and Morgause, Queen Morgause, King Arthur's half-sister, thus making him Arthur's nephew, as well as brother to Gawain, Agravain and Gaheris, and either a brother or half-brother of Mordred. Gareth is particularly notable in ''Le Morte d'Arthur'', where one of its eight books is named after and largely dedicated to him, and in which he is also known by his nickname Beaumains. Arthurian legend French literature The earliest role of Gareth, appearing as Guerrehet, is found in the First Continuation of Chrétien de Troyes's ''Perceval ou le Conte du Graal'' (in the original ''Perceval'', Chrétien himself had only mentioned Gawain's brothers named Agrevain, Gaherriez and Guerrehés). As the protagonist of the story's final episode, he slays the giant known as "Little Knight", thus avenging the death of fairy k ...
