Marcel-Paul Schützenberger
Marcel-Paul "Marco" Schützenberger (24 October 1920 – 29 July 1996) was a French mathematician and Doctor of Medicine. He worked in the fields of formal language, combinatorics, and information theory.Herbert Wilf, Dominique Foata, ''et al.'',In Memoriam: Marcel-Paul Schützenberger, 1920-1996," ''Electronic Journal of Combinatorics'', served from University of Pennsylvania Dept. of Mathematics Server, article dated 12 October 1996, retrieved from WWW on 4 November 2006. In addition to his formal results in mathematics, he was "deeply involved in struggle against the votaries of eo-arwinism",Foata, Dominique, "In Memoriam," ''op. cit.'' a stance which has resulted in some mixed reactions from his peers and from critics of his stance on evolution. Several notable theorems and objects in mathematics as well as computer science bear his name (for example Schutzenberger group or the Chomsky–Schützenberger hierarchy). Paul Schützenberger was his great-grandfather. In the lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

Formal Language
In logic, mathematics, computer science, and linguistics, a formal language consists of words whose letters are taken from an alphabet and are well-formed according to a specific set of rules. The alphabet of a formal language consists of symbols, letters, or tokens that concatenate into strings of the language. Each string concatenated from symbols of this alphabet is called a word, and the words that belong to a particular formal language are sometimes called ''well-formed words'' or ''well-formed formulas''. A formal language is often defined by means of a formal grammar such as a regular grammar or context-free grammar, which consists of its formation rules. In computer science, formal languages are used among others as the basis for defining the grammar of programming languages and formalized versions of subsets of natural languages in which the words of the language represent concepts that are associated with particular meanings or semantics. In computational complexity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WorldCat
WorldCat is a union catalog that itemizes the collections of tens of thousands of institutions (mostly libraries), in many countries, that are current or past members of the OCLC global cooperative. It is operated by OCLC, Inc. Many of the OCLC member libraries collectively maintain WorldCat's database, the world's largest bibliographic database. The database includes other information sources in addition to member library collections. OCLC makes WorldCat itself available free to libraries, but the catalog is the foundation for other subscription OCLC services (such as resource sharing and collection management). WorldCat is used by librarians for cataloging and research and by the general public. , WorldCat contained over 540 million bibliographic records in 483 languages, representing over 3 billion physical and digital library assets, and the WorldCat persons dataset (Data mining, mined from WorldCat) included over 100 million people.

Dominique Jean Larrey
Baron Dominique Jean Larrey (; 8 July 1766 – 25 July 1842) was a French surgeon and military doctor, who distinguished himself in the French Revolutionary Wars and the Napoleonic Wars. An important innovator in battlefield medicine and triage, he is often considered the first modern military surgeon. Early life and career Larrey was born in the little village of Beaudéan, in the Pyrenees as the son of a shoemaker, who later moved to Bordeaux. He was orphaned at the age of 13, and was then raised by his uncle Alexis, who was chief surgeon in Toulouse. After an 8-year apprenticeship, he went to Paris to study under Pierre-Joseph Desault, who was chief surgeon at the Hôtel-Dieu de Paris. Larrey then went to Brest, where he was appointed surgeon in the navy and began lecturing. In 1787 he boarded a ship deployed to the defense of Newfoundland, and was, at nearly 21 years-old at the time, the youngest medical officer in the French Royal Navy. While in America, Larrey took an inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anne Ancelin Schützenberger
Anne Ancelin Schützenberger (29 March 1919 – 23 March 2018) was a French psychologist and psychotherapist. During the Second World War she was a member of the French Resistance. She was born in Moscow, into a Jewish family, but grew up in Paris, where she received her education, leading eventually to doctorates in literature and psychology. As a result of her Resistance activities, she became regional secretary of the newly-formed Mouvement de libération nationale in 1944, and on 6 June of the same year her home was burned down by the 2nd SS Panzer Division Das Reich. Having gained experience working on the MLN's journal, in 1947 she launched the ''Bulletin de Psychologie des Étudiants de l'Université de Paris'', which she later edited, producing the first issue in the kitchen of her apartment. On 30 August 1948, she married the mathematician Marcel-Paul Schützenberger in London; they had one daughter, Hélène, but divorced soon afterwards. Through her husband she ca ...

Paul Schützenberger
Paul Schützenberger (23 December 1829 – 26 June 1897) was a French chemist. He was born in Strasbourg, where his father Georges Frédéric Schützenberger (1779–1859) was professor of law, and his uncle Charles Schützenberger (1809–1881) professor of chemical medicine. He was intended for a medical career and graduated MD from the University of Strasbourg in 1855, but his interests laid in physical and chemical sciences. In 1853 he went to Paris as preparateur to JF Persoz (1805–1868), professor of chemistry at the Conservatoire des Arts et Métiers. A year later he was entrusted with a course of chemical instruction at Mulhouse, and he remained in that town until 1865 as professor at the École Supérieure des Sciences. He then returned to Paris as assistant to AJ Balard at the College de France, in 1876 he succeeded him in the chair of chemistry, and in 1882 he became directing professor at the municipal École de Physique et de Chimie. The two latter chairs he hel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chomsky–Schützenberger Hierarchy
In formal language theory, computer science and linguistics, the Chomsky hierarchy (also referred to as the Chomsky–Schützenberger hierarchy) is a containment hierarchy of classes of formal grammars. This hierarchy of grammars was described by Noam Chomsky in 1956. It is also named after Marcel-Paul Schützenberger, who played a crucial role in the development of the theory of formal languages. Formal grammars A formal grammar of this type consists of a finite set of '' production rules'' (''left-hand side'' → ''right-hand side''), where each side consists of a finite sequence of the following symbols: * a finite set of ''nonterminal symbols'' (indicating that some production rule can yet be applied) * a finite set of ''terminal symbols'' (indicating that no production rule can be applied) * a ''start symbol'' (a distinguished nonterminal symbol) A formal grammar provides an axiom schema for (or ''generates'') a ''formal language'', which is a (usually infinite) s ...

Computer Science
Computer science is the study of computation, automation, and information. Computer science spans theoretical disciplines (such as algorithms, theory of computation, information theory, and automation) to Applied science, practical disciplines (including the design and implementation of Computer architecture, hardware and Computer programming, software). Computer science is generally considered an area of research, academic research and distinct from computer programming. Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of computational problem, problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and for preventing Vulnerability (computing), security vulnerabilities. Computer graphics (computer science), Computer graphics and computational geometry address the generation of images. Progr ...

Evolution
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes, which are passed on from parent to offspring during reproduction. Variation tends to exist within any given population as a result of genetic mutation and recombination. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or more rare within a population. The evolutionary pressures that determine whether a characteristic is common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules. The theory of evolution by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neo-Darwinism
Neo-Darwinism is generally used to describe any integration of Charles Darwin's theory of evolution by natural selection with Gregor Mendel's theory of genetics. It mostly refers to evolutionary theory from either 1895 (for the combinations of Darwin's and August Weismann's theories of evolution) or 1942 ( "modern synthesis"), but it can mean any new Darwinian- and Mendelian-based theory, such as the current evolutionary theory. Original use Darwin's theory of evolution by natural selection, as published in 1859, provided a selection mechanism for evolution, but not a trait transfer mechanism. Lamarckism was still a very popular candidate for this. August Weismann and Alfred Russel Wallace rejected the Lamarckian idea of inheritance of acquired characteristics that Darwin had accepted and later expanded upon in his writings on heredity. The basis for the complete rejection of Lamarckism was Weismann's germ plasm theory. Weismann realised that the cells that produce the germ plasm ...

Votary
Religious vows are the public vows made by the members of religious communities pertaining to their conduct, practices, and views. In the Buddhism tradition, in particular within the Mahayana and Vajrayana tradition, many different kinds of religious vows are taken by the lay community as well as by the monastic community, as they progress along the path of their practice. In the monastic tradition of all schools of Buddhism the Vinaya expounds the vows of the fully ordained Nuns and Monks. In the Christianity, Christian tradition, such public vows are made by the religious Cenobium, cenobitic and Hermit, eremitic of the Catholic Church, Lutheran Churches, Anglican Communion, and Eastern Orthodox Churches, whereby they confirm their public profession of the evangelical counsels of poverty, chastity, and obedience or Rule of St Benedict, Benedictine equivalent. The vows are regarded as the individual's free response to a call by God to follow Jesus Christ more closely under the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
