He was acclaimed for his virtuoso technique, his tone color, and the excitement engendered by his playing. He is recognized as one of the greatest pianists of all time., A pianist is an individual musician who plays the piano. Most forms of Western music can make use of the piano. Consequently, pianists have a wide variety of repertoire and styles to choose from, including traditionally classical music, Jazz, blues and all sorts of popular music, including rock music. Most pianists can, to a certain extent, play other keyboard-related instruments such as the synthesizer, harpsichord, celesta and the organ and keyboard. Perhaps the greatest pianist of all time was Franz Liszt, whose piano mastery was described by Anton Rubinstein: "In comparison with Liszt, all other pianists are children". , Ukraine (tr. ) is a sovereign state in Eastern Europe, bordered by Russia to the east and northeast, Belarus to the northwest, Poland and Slovakia to the west, Hungary, Romania, and Moldova to the southwest, and the Black Sea and Sea of Azov to the south and southeast, respectively. Ukraine is currently in territorial dispute with Russia over the Crimean Peninsula which Russia annexed in 2014 but which Ukraine and most of the international community recognise as Ukrainian. Including Crimea, Ukraine has an area of , making it the largest country entirely within Europe and the 46th largest country in the world. It has a population of about 44.5 million, making it the 32nd most populous country in the world., Miami University (also referred to as Miami U, Miami of Ohio, Miami University, Ohio, or simply Miami) is a coeducational public research university located in Oxford, Ohio, United States. Founded in 1809, although classes were not held until 1824, it is the 10th oldest public university in the United States and the second oldest university in Ohio. In its 2017 edition, U.S. News & World Report ranked the university 79th among national universities, the 30th top public school, and 2nd (1st among public institutions) for best undergraduate teaching at national universities. , Kiev or Kyiv is the capital and largest city of Ukraine, located in the north central part of the country on the Dnieper River.

The theatre has also hosted the Royal Variety Performance a record 40 times, most recently in 2014., NeWS (Network extensible Window System) is a discontinued windowing system developed by Sun Microsystems in the mid-1980s. Originally known as "SunDew", its primary authors were James Gosling and David S. H. Rosenthal. The NeWS interpreter was based on PostScript (as was the later Display PostScript, although the two projects were otherwise unrelated) extending it to allow interaction and multiple "contexts" to support windows. Like PostScript, NeWS could be used as a complete programming language, but unlike PostScript, NeWS could be used to make complete interactive programs with mouse support and a GUI., The National Broadcasting Company (NBC) is an American commercial broadcast television network that is the flagship property of NBCUniversal, a subsidiary of Comcast. The network is headquartered in the Comcast Building (formerly known as the GE Building) at Rockefeller Center in New York City, with additional major offices near Los Angeles (at Universal City Plaza), Chicago (at the NBC Tower) and soon in Philadelphia at Comcast Innovation and Technology Center. The network is part of the Big Three television networks. NBC is sometimes referred to as the "Peacock Network", in reference to its stylized peacock logo, which was originally created in 1956 for its then-new color broadcasts and became the network's official emblem in 1979., Play Your Cards Right ( or Bruce Forsyth 's Play Your Cards Right ) is a British television game show based on , and played similarly to , the American show known as Card Sharks ., Mark Goodson (January 14, 1915 December 18, 1992) was an American television producer who specialized in game shows, most frequently with his business partner Bill Todman, with whom he created Goodson-Todman Productions, You Bet! was a British game show based around the format of the German show "Wetten, dass..?" developed by Frank Elstner. "You Bet!" ran on ITV, mostly on Saturday nights but sometimes on Fridays, between 20 February 1988 and 12 April 1997, initially hosted by Bruce Forsyth from 1988 to 1990, then by Matthew Kelly from 1991 to 1995 and finally by Darren Day from 1996 to 1997. It was replaced the following year by "Don't Try This At Home!", which emulated the challenges of "You Bet!", but were considerably more risky and dangerous. A close successor debuted in 2016 with "Go For It!" , Sir Bruce Joseph Forsyth-Johnson (born 22 February 1928) is an English television presenter and entertainer whose career has spanned more than 75 years. In 2012, "Guinness World Records" recognised Forsyth as having the longest television career for a male entertainer.

Since then he has hosted several game shows, including "The Generation Game", "Play Your Cards Right", "The Price Is Right" and "You Bet!". He co-presented "Strictly Come Dancing" from 2004 to 2013. Forsyth is known for his catchphrases, "Nice to see you, to see you nice" and "Didn't he (/she/they) do well?"., William "Bill" Rafferty (June 17, 1944 August 11, 2012) was a comedian and impressionist who hosted the game shows "Every Second Counts" (1984-1985, syndicated), "Card Sharks" (198687, syndication), and "Blockbusters" (1987, NBC)., CBS (an initialism of the network's former name, the Columbia Broadcasting System) is an American commercial broadcast television network that is a flagship property of CBS Corporation. The company is headquartered at the CBS Building in New York City with major production facilities and operations in New York City (at the CBS Broadcast Center) and Los Angeles (at CBS Television City and the CBS Studio Center)., Television or TV is a telecommunication medium used for transmitting moving images in monochrome (black-and-white), or in color, and in two or three dimensions and sound. It can refer to a television set, a television program ("TV show"), or the medium of television transmission. Television is a mass medium, for entertainment, education, news, and advertising., Card Sharks is an American television game show created by Chester Feldman for Mark Goodson-Bill Todman Productions. Based on the card game Acey Deucey, the game has two contestants compete for control of a row of oversized playing cards by answering questions posed by the host and then guessing if the next card is higher or lower in value than the previous one. The concept has been made into a series four separate times since its debut in 1978, and also appeared as part of CBS's "Gameshow Marathon". The show originally ran on NBC from 1978 to 1981 with Jim Perry hosting; a revival ran from 1986 to 1989 on CBS with Bob Eubanks as host, accompanied by another version in syndication with Bill Rafferty. Gene Wood was the announcer on these three versions. Another syndicated revival aired from 2001 to 2002 with Pat Bullard as host and Gary Kroeger as announcer.

[EX Q]: Context: Abraham de Moivre (26 May 166727 November 1754) was a French mathematician known for de Moivre's formula, one of those that link complex numbers and trigonometry, and for his work on the normal distribution and probability theory. He was a friend of Isaac Newton, Edmond Halley, and James Stirling. Even though he faced religious persecution he remained a "steadfast Christian" throughout his life. Among his fellow Huguenot exiles in England, he was a colleague of the editor and translator Pierre des Maizeaux., England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight., Huguenots (or ) is a designation for an ethnoreligious group of French Protestants that follow the Reformed tradition., A definition is a statement of the meaning of a term (a word, phrase, or other set of symbols). Definitions can be classified into two large categories, intensional definitions (which try to give the essence of a term) and extensional definitions (which proceed by listing the objects that a term describes). Another important category of definitions is the class of ostensive definitions, which convey the meaning of a term by pointing out examples. A term may have many different senses and multiple meanings, and thus require multiple definitions., Probability theory is the branch of mathematics concerned with probability, the analysis of random phenomena. The central objects of probability theory are random variables, stochastic processes, and events: mathematical abstractions of non-deterministic events or measured quantities that may either be single occurrences or evolve over time in an apparently random fashion., In mathematics , Stirling 's approximation ( or Stirling 's formula ) is an approximation for factorials . It is a very powerful approximation , leading to accurate results even for small values of n. It is named after James Stirling , though it was first stated by Abraham de Moivre . The formula as typically used in applications is \ ln ( n ! ) = n \ ln ( n ) - n + O ( \ ln ( n ) ) ( in big O notation ) . The next term in the O ( ln ( n ) ) is 1/2ln ( 2n ) ; a more precise variant of the formula is therefore n ! \ sim \ sqrt ( 2 \ pi n ) \ left ( \ frac ( n ) ( e ) \ right ) ^ n. It is also possible to give a version of Stirling 's formula with bounds valid for all positive integers n , rather than asymptotics : one has \ sqrt ( 2 \ pi ) \ n ^ ( n + \ frac12 ) e ^ ( - n ) \ le n ! \ le e \ n ^ ( n + \ frac12 ) e ^ ( - n ) for all positive integers n. Thus the ratio \ frac ( n ! ) ( n ^ ( n + \ frac12 ) e ^ ( - n ) ) is always between 2 = 2.5066 ... and e = 2.71828 ... . As an asymptotic formula , Stirling 's approximation has the property that the ratio \ frac ( n ! ) ( \ sqrt ( 2 \ pi n ) \ left ( \ frac ( n ) ( e ) \ right ) ^ n ) approaches 1 as n grows to infinity ., Trigonometry (from Greek "trignon", "triangle" and "metron", "measure") is a branch of mathematics that studies relationships involving lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies., Pierre des Maizeaux, also spelled Desmaizeaux (c. 1666 or 1673June 1745), was a French Huguenot writer exiled in London, best known as the translator and biographer of Pierre Bayle., In mathematics, de Moivre's formula (also known as de Moivre's theorem and de Moivre's identity), named after Abraham de Moivre, states that for any complex number (and, in particular, for any real number) and integer it holds that, A mathematician is someone who uses an extensive knowledge of mathematics in his/her work, typically to solve mathematical problems., Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework., Sir Isaac Newton (25 December 1642 20 March 1726/27) was an English mathematician, astronomer, and physicist (described in his own day as a "natural philosopher") who is widely recognised as one of the most influential scientists of all time and a key figure in the scientific revolution. His book "Philosophi Naturalis Principia Mathematica" ("Mathematical Principles of Natural Philosophy"), first published in 1687, laid the foundations of classical mechanics. Newton also made seminal contributions to optics, and he shares credit with Gottfried Wilhelm Leibniz for developing the infinitesimal calculus., A complex number is a number that can be expressed in the form , where and are real numbers and is the imaginary unit, satisfying the equation . In this expression, is the ' and is the ' of the complex number. If formula_1, then formula_2, Quantity is a property that can exist as a magnitude or multitude. Quantities can be compared in terms of "more", "less", or "equal", or by assigning a numerical value in terms of a unit of measurement. Quantity is among the basic classes of things along with quality, substance, change, and relation. Some quantities are such by their inner nature (as number), while others are functioning as states (properties, dimensions, attributes) of things such as heavy and light, long and short, broad and narrow, small and great, or much and little. A small quantity is sometimes referred to as a quantulum., Mathematics (from Greek "mathma", knowledge, study, learning) is the study of topics such as quantity (numbers), structure, space, and change. There is a range of views among mathematicians and philosophers as to the exact scope and definition of mathematics., Subject: stirling's approximation, Relation: instance_of, Options: (A) 25 (B) branch (C) complex number (D) definition (E) designation (F) editor (G) england (H) fashion (I) field (J) five (K) formula (L) four (M) identity (N) integer (O) island (P) key (Q) magnitude (R) mathematics (S) may (T) measurement (U) number (V) phrase (W) position (X) property (Y) quality (Z) quantity ([) range (\) real number (]) relation (^) relationship (_) space (') statement (a) structure (b) study (c) theorem (d) theory (e) three (f) time (g) translator (h) triangle (i) two (j) unit of measurement (k) word (l) work
