R.K. Guy
Richard Kenneth Guy (30 September 1916 – 9 March 2020) was a British mathematician. He was a professor in the Department of Mathematics at the University of Calgary. He is known for his work in number theory, geometry, recreational mathematics, combinatorics, and graph theory. He is best known for co-authorship (with John Horton Conway, John Conway and Elwyn Berlekamp) of ''Winning Ways for your Mathematical Plays'' and authorship of ''Unsolved Problems in Number Theory''. He published more than 300 scholarly articles. Guy proposed the partially tongue-in-cheek "strong law of small numbers", which says there are not enough small integers available for the many tasks assigned to them – thus explaining many coincidences and patterns found among numerous cultures. For this paper he received the MAA Paul R. Halmos – Lester R. Ford Award, Lester R. Ford Award. Biography Early life Guy was born 30 September 1916 in Nuneaton, Warwickshire, England, to Adeline Augusta Tanner and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

British Undergraduate Degree Classification
The British undergraduate degree classification system is a Grading in education, grading structure used for undergraduate degrees or bachelor's degrees and Master's degree#Integrated Masters Degree, integrated master's degrees in the United Kingdom. The system has been applied, sometimes with significant variation, in other countries and regions. The UK's university degree classification system, established in 1918, serves to recognize academic achievement beyond examination performance. Bachelor's degrees in the UK can either be honours or ordinary degrees, with honours degrees classified into First Class, Upper Second Class (2:1), Lower Second Class (2:2), and Third Class based on weighted averages of marks. The specific thresholds for these classifications can vary by institution. Integrated master's degrees follow a similar classification, and there is some room for discretion in awarding final classifications based on a student's overall performance and work quality.

Chess Problem
A chess problem, also called a chess composition, is a puzzle created by the composer using chess pieces on a chessboard, which presents the solver with a particular task. For instance, a position may be given with the instruction that White is to move first, and checkmate Black in two moves against any possible defence. A chess problem fundamentally differs from play in that the latter involves a struggle between Black and White, whereas the former involves a competition between the composer and the solver. Most positions which occur in a chess problem are unrealistic in the sense that they are very unlikely to occur in over-the-board play. There is a substantial amount of specialized jargon used in connection with chess problems. Definition The term chess problem is not sharply defined: there is no clear demarcation between chess compositions on the one hand and puzzle or tactical exercises on the other. In practice, however, the distinction is very clear. There are common c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of The Theory Of Numbers
''History of the Theory of Numbers'' is a three-volume work by Leonard Eugene Dickson summarizing work in number theory up to about 1920. The style is unusual in that Dickson mostly just lists results by various authors, with little further discussion. The central topic of quadratic reciprocity and higher reciprocity laws is barely mentioned; this was apparently going to be the topic of a fourth volume that was never written .

Leonard Eugene Dickson
Leonard Eugene Dickson (January 22, 1874 – January 17, 1954) was an American mathematician. He was one of the first American researchers in abstract algebra, in particular the theory of finite fields and classical groups, and is also remembered for a three-volume history of number theory, '' History of the Theory of Numbers''. The L. E. Dickson instructorships at the University of Chicago Department of Mathematics are named after him. Life Dickson considered himself a Texan by virtue of having grown up in Cleburne, where his father was a banker, merchant, and real estate investor. He attended the University of Texas at Austin, where George Bruce Halsted encouraged his study of mathematics. Dickson earned a B.S. in 1893 and an M.S. in 1894, under Halsted's supervision. Dickson first specialised in Halsted's own specialty, geometry. A. A.
