High Quality Content by WIKIPEDIA articles! In mathematics before the 1970s, the term umbral calculus was understood to mean the surprising similarities between otherwise unrelated polynomial equations, and certain shadowy techniques that can be used to 'prove' them. These techniques were introduced by John Blissard in 1861 and are sometimes called Blissard's symbolic method. They are often attributed to Édouard Lucas (or James Joseph Sylvester), who used the technique extensively.In the 1930s and 1940s, Eric Temple Bell attempted to set the umbral calculus on a rigorous footing, perhaps not altogether successfully.In the 1970s, Steven Roman, Gian-Carlo Rota, and others developed the umbral calculus by means of linear functionals on spaces of polynomials.

Excerpt: Cyril Lionel Robert James (4 January 1901 19 May 1989) who also adopted the pen-name of J.R. Johnson was an Afro-Trinidadian historian, journalist, socialist theorist and essayist. He was influential in the United Kingdom and the United States in socialist parties and Marxist thought, as well as leading ideas about the end of colonialism. He is also famed as a writer on cricket. Born in Trinidad and Tobago, then a British Crown colony, James attended Queen's Royal College in Port of Spain before becoming a cricket journalist, and also an author of fiction. He later worked as a school teacher, teaching among others the young Eric Williams, later the first Prime Minister of Trinidad and Tobago. Together with Ralph de Boissière, Albert Gomes and Alfred Mendes, James was a member of the anti-colonialist Beacon Group, a circle of writers associated with The Beacon magazine. In 1932, he moved to Nelson in Lancashire, England as his friend, and West Indian cricketer, Learie Constantine's biographer, plus a hope of furthering his literary career. There he worked for the Manchester Guardian and helped the cricketer Learie Constantine write his autobiography. In 1933, James left his home in the small Lancashire town of Nelson and moved to London. James had begun to campaign for the independence of the West Indies while in Trinidad, and his Life of Captain Cipriani and the pamphlet The Case for West-Indian Self Government were his first important published works. Now he became a leading champion of Pan-African agitation and the Chair of the International African Friends of Abyssinia, formed in 1935 in response ...More: http://booksllc.net/?id=437867 ...
