Catalonia
Catalonia (; ca, Catalunya ; Aranese Occitan: ''Catalonha'' ; es, Cataluña ) is an autonomous community of Spain, designated as a ''nationality'' by its Statute of Autonomy. Most of the territory (except the Val d'Aran) lies on the northeast of the Iberian Peninsula, to the south of the Pyrenees mountain range. Catalonia is administratively divided into four provinces: Barcelona, Girona, Lleida, and Tarragona. The capital and largest city, Barcelona is the second-most populated municipality in Spain and the fifth-most populous urban area in the European Union.Demographia: World Urban Areas – Demographia, April 2018 Current day Catalonia comprises most of the medieval and early modern Principality o ...

Alex Catalán
Alejandro Catalán (11 December 1968 in El Pobo de Dueñas, Spain – present) better known as Alex Catalán, is a Spanish director of photography, who has worked in more than 20 feature films and other short films which have won several prizes. Biography One of his first jobs related with the audiovisual sector was when her sister, who was a 1st. Camera Assistant, gave him the opportunity of working as a Clapper/Loader in a commercial for the Spanish National Organization for the blind (ONCE) at the Puerta del Sol of Madrid in the mid – 80s. There he found out the intensity of the professional filming. He also started working as press photographer. Although he matriculated at biology at the Universidad de Sevilla, he was more attracted by the photography. But not only photography, he also has always loved scuba diving. He attended the schools from Madrid, London, Los Angeles and Cuba and after passing the public examination, he started working as a camera operator in the publ ...

Catalan Wine
Catalan wines are those that are produced in the wine region of Catalonia. Occasionally, the appellation is applied to some French wine made in the Catalan region of Roussillon also known as Northern Catalonia or the ''Pays catalans''. The city of Barcelona is the capital of Catalonia and despite not being in a wine region (although a portion of the Penedès is in the greater comarca of Barcelona) it is the focal point of the Catalan wine industry: a primary consumer market, its port provides export functions and a source of financial resources and investment. The area has a long winemaking tradition and was the birthplace of the sparkling wine ''Cava'', invented in the early 1870s in Sant Sadurní d'Anoia by Josep Raventos of Codorníu Winery. At the turn of the 20th century, the Catalan wine industry was at the forefront of Spain's emergence as a world leader in quality wine production, being the first Spanish wine region to adopt the use of stainless steel fermentation tanks.

Catalan's Conjecture
Catalan's conjecture (or Mihăilescu's theorem) is a theorem in number theory that was Conjecture, conjectured by the mathematician Eugène Charles Catalan in 1844 and proven in 2002 by Preda Mihăilescu at Paderborn University. The integers 23 and 32 are two perfect powers (that is, powers of exponent higher than one) of natural numbers whose values (8 and 9, respectively) are consecutive. The theorem states that this is the ''only'' case of two consecutive perfect powers. That is to say, that History The history of the problem dates back at least to Gersonides, who proved a special case of the conjecture in 1343 where (''x'', ''y'') was restricted to be (2, 3) or (3, 2). The first significant progress after Catalan made his conjecture came in 1850 when Victor-Amédée Lebesgue dealt with the case ''b'' = 2. In 1976, Robert Tijdeman applied Baker's method in transcendental number theory, transcendence theory to establish a bound on a,b and used existing results bounding '' ...

Catalan's Constant
In mathematics, Catalan's constant , is defined by : G = \beta(2) = \sum_^ \frac = \frac - \frac + \frac - \frac + \frac - \cdots, where is the Dirichlet beta function. Its numerical value is approximately : It is not known whether is irrational number, irrational, let alone transcendental number, transcendental. has been called "arguably the most basic constant whose irrationality and transcendence (though strongly suspected) remain unproven". Catalan's constant was named after Eugène Charles Catalan, who found quickly-converging series for its calculation and published a memoir on it in 1865. Uses In low-dimensional topology, Catalan's constant is 1/4 of the volume of an ideal polyhedron, ideal hyperbolic octahedron, and therefore 1/4 of the hyperbolic volume of the complement of the Whitehead link. It is 1/8 of the volume of the complement of the Borromean rings. In combinatorics and statistical mechanics, it arises in connection with counting domino tilings, spannin ...

Catalan Number
In combinatorial mathematics, the Catalan numbers are a sequence of natural numbers that occur in various counting problems, often involving recursively defined objects. They are named after the French-Belgian mathematician Eugène Charles Catalan (1814–1894). The ''n''th Catalan number can be expressed directly in terms of binomial coefficients by :C_n = \frac = \frac = \prod\limits_^\frac \qquad\textn\ge 0. The first Catalan numbers for ''n'' = 0, 1, 2, 3, ... are :1, 1, 2, 5, 14, 42, 132, 429, 1430, 4862, 16796, 58786, ... . Properties An alternative expression for ''C''''n'' is :C_n = - for n\ge 0, which is equivalent to the expression given above because \tbinom=\tfrac\tbinomn. This expression shows that ''C''''n'' is an integer, which is not immediately obvious from the first formula given. This expression forms the basis for a proof of the correctness of the formula. The Catalan numbers satisfy the recurrence relations :C_0 = 1 \quad \text \quad C_=\sum_^C_i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Moses Chayyim Catalan
Moses Chayyim Catalan (b. Padua, Italy, d. 1661, Padua) was an Italian poet. A son of the physician Abraham Catalan, he was rabbi in his native town, and died there at an advanced age in 1661. It was to him that the first letters of Isaac Vita Cantarini, whose teacher he was, were addressed. His "Metzaref ha-Sekel", a rhetorical pamphlet on man, has never been published. He wrote a poem in honor of the marriage of his sister Perla to Raphael Gans Levi, which can be read either as Hebrew or as Italian. It has been reprinted by Johann Christoph Wolf, ''Bibliotheca Hebræa'' iii. 726. In 1645 he wrote a similar poem in honor of Shabbethai Astruc. An elegy on Lamentations in ''ottava rima'' was also published by him at Padua.

Eugène Charles Catalan
Eugène Charles Catalan (30 May 1814 – 14 February 1894) was a French and Belgian mathematician who worked on continued fractions, descriptive geometry, number theory and combinatorics. His notable contributions included discovering a periodic minimal surface in the space \mathbb^3; stating the famous Catalan's conjecture, which was eventually proved in 2002; and, introducing the Catalan number to solve a combinatorial problem. Biography Catalan was born in Bruges (now in Belgium, then under Dutch rule even though the Kingdom of the Netherlands had not yet been formally instituted), the only child of a French jeweller by the name of Joseph Catalan, in 1814. In 1825, he traveled to Paris and learned mathematics at École Polytechnique, where he met Joseph Liouville (1833). In December 1834 he was expelled along with most of the students in his year for political reasons; he resumed his studies in January 1835, graduated that summer, and went on to teach at Châlons-sur-Marne. ...
