Robert Harley (mathematician)
Robert Harley (23 January 1828 – 26 July 1910) was an English Congregational minister and mathematician. Life Born in Liverpool on 23 January 1828, he was third son of Robert Harley by his wife Mary, daughter of William Stevenson, and niece of General Stevenson of Ayr.. The father, after a career as a merchant, became a minister of the Wesleyan Methodist Association. Harley's mathematical aptitude developed at school in Blackburn under William Hoole, and age 16 he was appointed to a mathematical mastership at Seacombe, near Liverpool, returning later to teach at Blackburn. In 1854 Harley entered the Congregational ministry, and was at Brighouse, Yorkshire, until 1868, after a time also filling the chair of mathematics and logic at Airedale College from 1864 to 1868. In 1863 he was admitted Fellow of the Royal Society. He acted as secretary of the A section of the British Association at meetings at Norwich (1868) and Edinburgh (1871); and was a vice-president of the meetings at Br ...

Temperance (virtue)
Temperance in its modern use is defined as moderation or voluntary self-restraint. It is typically described in terms of what an individual voluntarily refrains from doing. This includes restraint from revenge by practicing non-violence and forgiveness, restraint from arrogance by practicing humility and modesty, restraint from excesses such as extravagant luxury or splurging, and restraint from rage or craving by practicing calmness and self-control. Temperance has been described as a virtue by religious thinkers, philosophers, and more recently, psychologists, particularly in the positive psychology movement. It has a long history in philosophical and religious thought. In classical iconography, the virtue is often depicted as a woman holding two vessels transferring water from one to another. It is one of the cardinal virtues in western thought found in Greek philosophy and Christianity, as well as eastern traditions such as Buddhism and Hinduism. Temperance is one of the ...

1910 Deaths
Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Mark Ambient
Harold Harley (20 June 1860 – 11 August 1937), known by his pen name Mark Ambient, was an English actor and dramatist. He is particularly noted as a writer of the musical comedy '' The Arcadians'', first produced in 1909. He was born in Rastrick, Yorkshire, son of Robert Harley, a Congregational minister and mathematician. He was educated at Mill Hill School in London, where his father was vice-principal, and King's College, Cambridge, graduating BA in 1884.''Alumni Cantabrigienses: A Biographical List of All Known Students, Graduates and Holders of Office at the University of Cambridge, from the Earliest Times to 1900'' Volume 2, page 246.

George Boole
George Boole (; 2 November 1815 – 8 December 1864) was a largely self-taught English mathematician, philosopher, and logician, most of whose short career was spent as the first professor of mathematics at Queen's College, Cork in Ireland. He worked in the fields of differential equations and algebraic logic, and is best known as the author of '' The Laws of Thought'' (1854) which contains Boolean algebra. Boolean logic is credited with laying the foundations for the Information Age. Early life Boole was born in 1815 in Lincoln, Lincolnshire, England, the son of John Boole senior (1779–1848), a shoemaker and Mary Ann Joyce. He had a primary school education, and received lessons from his father, but due to a serious decline in business, he had little further formal and academic teaching. William Brooke, a bookseller in Lincoln, may have helped him with Latin, which he may also have learned at the school of Thomas Bainbridge. He was self-taught in modern la ...

Quintic Function
In algebra, a quintic function is a function of the form :g(x)=ax^5+bx^4+cx^3+dx^2+ex+f,\, where , , , , and are members of a field, typically the rational numbers, the real numbers or the complex numbers, and is nonzero. In other words, a quintic function is defined by a polynomial of degree five. Because they have an odd degree, normal quintic functions appear similar to normal cubic functions when graphed, except they may possess one additional local maximum and one additional local minimum. The derivative of a quintic function is a quartic function. Setting and assuming produces a quintic equation of the form: :ax^5+bx^4+cx^3+dx^2+ex+f=0.\, Solving quintic equations in terms of radicals (''n''th roots) was a major problem in algebra from the 16th century, when cubic and quartic equations were solved, until the first half of the 19th century, when the impossibility of such a general solution was proved with the Abel–Ruffini theorem. Finding roots of a quintic equa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur Cayley
Arthur Cayley (; 16 August 1821 – 26 January 1895) was a prolific British mathematician who worked mostly on algebra. He helped found the modern British school of pure mathematics. As a child, Cayley enjoyed solving complex maths problems for amusement. He entered Trinity College, Cambridge, where he excelled in Greek, French, German, and Italian, as well as mathematics. He worked as a lawyer for 14 years. He postulated the Cayley–Hamilton theorem—that every square matrix is a root of its own characteristic polynomial, and verified it for matrices of order 2 and 3. He was the first to define the concept of a group in the modern way—as a set with a binary operation satisfying certain laws. Formerly, when mathematicians spoke of "groups", they had meant permutation groups. Cayley tables and Cayley graphs as well as Cayley's theorem are named in honour of Cayley. Early years Arthur Cayley was born in Richmond, London, England, on 16 August 1821. His father, Hen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
