Bogdan Suceavă
Bogdan Suceavă (born September 27, 1969) is a Romanian-American mathematician and writer. Biography He was born in Curtea de Argeș, Romania. Growing up, Suceavă spent his holidays with his maternal grandparents at Nucșoara, a remote community that maintained its traditions, unbroken by the collectivisation elsewhere of Nicolae Ceaușescu's regime. There he absorbed Balkan folk-tales and myths, which would inform some of his literary works. Suceavă mentioned his maternal grandmother was a cousin of Elisabeta Rizea, a figure of the Romanian anti-communist resistance movement. Suceavă went to school in Pitești, Găești, Târgoviște, and Bucharest, as his family moved several times. After the Romanian Revolution of 1989, he attended the University of Bucharest, where he obtained his undergraduate degree in mathematics and master's degree in mathematics, with a focus on geometry. He then moved to the United States to study at the Michigan State University for his doctorate. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curtea De Argeș
Curtea de Argeș () is a municipality in Romania on the left bank of the river Argeș, where it flows through a valley of the Southern Carpathians (the Făgăraș Mountains), on the railway from Pitești to the Turnu Roșu Pass. It is part of Argeș County. The city also administers one village, Noapteș. On July 7, 1947, the total rainfall in Curtea de Argeș was in 20 minutes, which is a world record. Etymology and names The present name, literally ''The Court upon (river) Argeș'', refers to the former status of the town as the capital of Wallachia. Some historians identify the Argeș River with ancient " Ordessos", however the name is unlikely to be derived from this name. The oldest Slavonic documents use an "Arghiș" form, which might suggest a Cuman or Pecheneg etymology, from the root ''arghiš'' ("higher ground", "heights"). The original name was Argeș, which was then used for the name of the river as well. History Capital of Wallachia One of the oldes ...

Găești
Găești () is a town in Dâmbovița County, Muntenia, Romania with a population of 12,767. History The name of the town comes from a family of nobles (boyars) who owned most of the lands on which the town is now situated. Their name was Găești. It was first mentioned on 19 July 1498 during the rule of Radu cel Mare, the son of Vlad Călugărul, who donated the land around Găești to the Monastery of Râncăciov. In 1807, most of the buildings of Găești were destroyed by a fire, then in 1812, it was hit by the plague. Demographics According to the census conducted in 2011, the population of Găești is of 13,317 inhabitants. The majority of the inhabitants are Romanians (93.41%), with a minority of Roma (1.71%). For 4.68% of the population, the ethnicity is unknown. Most of the inhabitants are Orthodox (93.97%). Economy Arctic S.A. company is headquartered in the town.

Felix Klein
Christian Felix Klein (; 25 April 1849 – 22 June 1925) was a German mathematician and mathematics educator, known for his work with group theory, complex analysis, non-Euclidean geometry, and on the associations between geometry and group theory. His 1872 Erlangen program, classifying geometries by their basic symmetry groups, was an influential synthesis of much of the mathematics of the time. Life Felix Klein was born on 25 April 1849 in Düsseldorf, to Prussian parents. His father, Caspar Klein (1809–1889), was a Prussian government official's secretary stationed in the Rhine Province. His mother was Sophie Elise Klein (1819–1890, née Kayser). He attended the Gymnasium in Düsseldorf, then studied mathematics and physics at the University of Bonn, 1865–1866, intending to become a physicist. At that time, Julius Plücker had Bonn's professorship of mathematics and experimental physics, but by the time Klein became his assistant, in 1866, Plücker's interest wa ...

Dan Barbilian
Ion Barbu (, pen name of Dan Barbilian; 18 March 1895 –11 August 1961) was a Romanian mathematician and poet. His name is associated with the Mathematics Subject Classification number 51C05, which is a major posthumous recognition reserved only to pioneers of investigations in an area of mathematical inquiry. Early life Born in Câmpulung-Muscel, Argeș County, he was the son of Constantin Barbilian and Smaranda, born Șoiculescu. He attended elementary school in Câmpulung, Dămienești, and Stâlpeni, and for secondary studies he went to the Ion Brătianu High School in Pitești, the Dinicu Golescu High School in Câmpulung, and finally the Gheorghe Lazăr High School and the Mihai Viteazul High School in Bucharest. During that time, he discovered that he had a talent for mathematics, and started publishing in ''Gazeta Matematică''; it was also then that he discovered his passion for poetry.

Differential Geometry
Differential geometry is a mathematical discipline that studies the geometry of smooth shapes and smooth spaces, otherwise known as smooth manifolds. It uses the techniques of differential calculus, integral calculus, linear algebra and multilinear algebra. The field has its origins in the study of spherical geometry as far back as antiquity. It also relates to astronomy, the geodesy of the Earth, and later the study of hyperbolic geometry by Lobachevsky. The simplest examples of smooth spaces are the plane and space curves and surfaces in the three-dimensional Euclidean space, and the study of these shapes formed the basis for development of modern differential geometry during the 18th and 19th centuries. Since the late 19th century, differential geometry has grown into a field concerned more generally with geometric structures on differentiable manifolds. A geometric structure is one which defines some notion of size, distance, shape, volume, or other rigidifying structu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Professor
Professor (commonly abbreviated as Prof.) is an Academy, academic rank at university, universities and other post-secondary education and research institutions in most countries. Literally, ''professor'' derives from Latin as a "person who professes". Professors are usually experts in their field and teachers of the highest rank. In most systems of List of academic ranks, academic ranks, "professor" as an unqualified title refers only to the most senior academic position, sometimes informally known as "full professor". In some countries and institutions, the word "professor" is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States, where the unqualified word is also used colloquially to refer to associate and assistant professors as well. This usage would be considered incorrect among other academic communities. However, the otherwise unqualified title "Professor" designated with a capital let ...

Stere Ianuș
The stere or stère (st) is a unit of volume in the original metric system equal to one cubic metre. The stere is typically used for measuring large quantities of firewood or other cut wood, while the cubic meter is used for uncut wood. The name was coined from the Greek στερεός ''stereós'', "solid", in 1795 in France as a metric analogue to the cord. The unit was introduced to remove regional disparities of this former unit, for which the length could vary greatly from 6 to 13.5 m. It is not part of the modern metric system (SI) and is no longer a legal unit in France, but remains used in the commerce of firewood. Background The correspondence between stere and cubic meter of stacked wood is imprecise because it depends on the length of the logs used and on how irregular they are. The stere corresponds to 1 m3 of wood, made exclusively with logs of 1 m in length, all stacked parallel and neatly arranged. If the length of the logs is less than 1 m, the volume of visib ...

Ion Colojoară
An ion () is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of electrons is unequal to its total number of protons. A cation is a positively charged ion with fewer electrons than protons while an anion is a negatively charged ion with more electrons than protons. Opposite electric charges are pulled towards one another by electrostatic force, so cations and anions attract each other and readily form ionic compounds. Ions consisting of only a single atom are termed atomic or monatomic ions, while two or more atoms form molecular ions or polyatomic ions. In the case of physical ionization in a fluid (gas or liquid), "ion pairs" are created by spontaneous molecule collisions, where each generated pair consists of a free electron and ...
