Republic Of Geneva
The Canton of Geneva, officially the Republic and Canton of Geneva (french: link=no, République et canton de Genève; frp, Rèpublica et canton de Geneva; german: Republik und Kanton Genf; it, Repubblica e Cantone di Ginevra; rm, Republica e chantun Genevra), is one of the 26 cantons forming the Swiss Confederation. It is composed of forty-five municipalities and the seat of the government and parliament is in the City of Geneva. Geneva is the French-speaking westernmost canton of Switzerland. It lies at the western end of Lake Geneva and on both sides of the Rhone, its main river. Within the country, the canton shares borders with Vaud to the east, the only adjacent canton. However, the borders of the canton are essentially international, with the French region of Auvergne-Rhône-Alpes. As is the case in several other Swiss cantons (Ticino, Neuchâtel, and Jura), Geneva is referred to as a republic within the Swiss Confederation. One of the most populated cantons, Genev ...

Historical Dictionary Of Switzerland
The ''Historical Dictionary of Switzerland'' is an encyclopedia on the history of Switzerland that aims to take into account the results of modern historical research in a manner accessible to a broader audience. The encyclopedia is published by a foundation under the patronage of the Swiss Academy of Humanities and Social Sciences (SAGW/ASSH) and the Swiss Historical Society (SGG-SHH) and is financed by national research grants. Besides a staff of 35 at the central offices, the contributors include 100 academic advisors, 2500 historians and 100 translators. Print edition The encyclopedia is published simultaneously in three of Switzerland's national languages: German (''Historisches Lexikon der Schweiz'', HLS, in red), French (''Dictionnaire Historique de la Suisse'', DHS, in blue) and Italian Italian(s) may refer to: * Anything of, from, or related to the people of Italy over the centuries ** Italians, an ethnic group or simply a citizen of the Italian Republic or ...

Differential Equation
In mathematics, a differential equation is an equation that relates one or more unknown functions and their derivatives. In applications, the functions generally represent physical quantities, the derivatives represent their rates of change, and the differential equation defines a relationship between the two. Such relations are common; therefore, differential equations play a prominent role in many disciplines including engineering, physics, economics, and biology. Mainly the study of differential equations consists of the study of their solutions (the set of functions that satisfy each equation), and of the properties of their solutions. Only the simplest differential equations are solvable by explicit formulas; however, many properties of solutions of a given differential equation may be determined without computing them exactly. Often when a closed-form expression for the solutions is not available, solutions may be approximated numerically using computers. The theory of d ...

Finite Difference
A finite difference is a mathematical expression of the form . If a finite difference is divided by , one gets a difference quotient. The approximation of derivatives by finite differences plays a central role in finite difference methods for the numerical solution of differential equations, especially boundary value problems. The difference operator, commonly denoted \Delta is the operator that maps a function to the function \Delta /math> defined by :\Delta x)= f(x+1)-f(x). A difference equation is a functional equation that involves the finite difference operator in the same way as a differential equation involves derivatives. There are many similarities between difference equations and differential equations, specially in the solving methods. Certain recurrence relations can be written as difference equations by replacing iteration notation with finite differences. In numerical analysis, finite differences are widely used for approximating derivatives, and the term " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Probability Theory
Probability theory is the branch of mathematics concerned with probability. Although there are several different probability interpretations, probability theory treats the concept in a rigorous mathematical manner by expressing it through a set of axioms. Typically these axioms formalise probability in terms of a probability space, which assigns a measure taking values between 0 and 1, termed the probability measure, to a set of outcomes called the sample space. Any specified subset of the sample space is called an event. Central subjects in probability theory include discrete and continuous random variables, probability distributions, and stochastic processes (which provide mathematical abstractions of non-deterministic or uncertain processes or measured quantities that may either be single occurrences or evolve over time in a random fashion). Although it is not possible to perfectly predict random events, much can be said about their behavior. Two major results in probability ...

Abraham Trembley
Abraham Trembley (3 September 1710 – 12 May 1784 Geneva) was a Genevan naturalist. He is best known for being the first to study freshwater polyps or '' hydra'' and for being among the first to develop experimental zoology. His mastery of experimental method has led some historians of science to credit him as the "father of biology". He also wrote on religion and morals. Biography Trembley came from an officer's family from Geneva, Republic of Geneva. He was uncle to Charles Bonnet, with whom he corresponded regularly, as well as to René-Antoine Ferchault de Réaumur (1683–1757) and Lazzaro Spallanzani (1729–1799). Trembley acted as tutor to the two children of Count Willem Bentinck van Rhoon (1704–1774), a prominent Dutch politician at the time. The boys were 3 and 6 when Trembley, during lessons in which he went fishing in the ponds outside the house, accidentally discovered the regenerative powers of the Hydra. Those lessons took place at the Count's summer residenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacques-André Mallet
Jacques-André Mallet (); also Mallet-Favre; 23 September 1740 – 31 January 1790) was a Genevan mathematician and astronomer. In 1772, Mallet established and co-financed the first Geneva Observatory, and served as its director until his death in 1790. His research primarily concerned occultations, especially lunar eclipse, lunar and solar eclipse, solar eclipses, sunspots, Orbit#Planetary orbits, planetary orbits, and the orbits of the moons of Jupiter. Biography Early life and education Jacques-André was born in Geneva to Jean-Robert, a Ranks in the French Army#Officiers subalternes - junior officers, captain in the French Army, and his wife, Dorothée Favre, both of Nobility, noble lineage. Jean-Robert was from a branch of the Mallet family of Huguenot merchants and bankers who had fled from Rouen to Geneva in 1557 to escape growing Anti-Protestantism, religious persecution. Through his mother, Dorothée, Jacques-André was also a direct descendant of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Bonnet
Charles Bonnet (; 13 March 1720 – 20 May 1793) was a Genevan naturalist and philosophical writer. He is responsible for coining the term ''phyllotaxis'' to describe the arrangement of leaves on a plant. He was among the first to notice parthenogenetic reproduction in aphids and established that insects respired through their spiracles. He was among the first to use the term "evolution" in a biological context. Deaf from an early age, he also suffered from failing eyesight and had to make use of assistants in later life to help in his research. Life and work Bonnet was born in Geneva, the son of Pierre Bonnet and Anne-Marie Lullin de Châteauvieux. Although originally from France, the family had been driven into Geneva by religious persecution of Protestants in the 16th century. At age seven he lost hearing which pushed him into an interest in the natural world. His schoolmates troubled him due to the hearing handicap and the parents took him out and had a private tutor.
