Enrico D'Ovidio
Enrico D'Ovidio (1842-1933) was an Italian mathematician who is known by his works on geometry. Life and work D'Ovidio, son of a liberal parents involved in the Italian independence movement, studied at the university of Naples under his uncle, Achille Sannia, who prepared him to enter in the School of Bridges and Roads. In 1869, he published with Sannia a very successful textbook to teach geometry in the schools. Encouraged by Eugenio Beltrami, he obtained the chair on Algebra and Analytic Geometry at the university of Turin in 1872, and he remained there for the remaining 46 years of his life. He was also rector of the university from 1880 to 1885. The research of D'Ovidio was mainly in geometry and the most important works were produced when he was in Turin. Specially interesting is his work Le funzioni metriche fondamentali negli spazi di quante si vogliono dimensioni e di curvatura costante(The fundamental metrical functions in the n-dimensional spaces of constant curva ...

Campobasso
Campobasso (, ; nap, label= Campobassan, Cambuàsce ) is a city and ''comune'' in southern Italy, the capital of the region of Molise and of the province of Campobasso. It is located in the high basin of the Biferno river, surrounded by Sannio and Matese mountains. Campobasso is renowned for the craftsmanship of blades (including scissors and knives), a fact well documented since the 14th century. It is also famous for the production of pears and scamorza (cheese). The city is the home of the University of Molise and of the Archdiocese of Campobasso-Boiano. History The origins of Campobasso are disputed. According to the most widely held theory, the city was founded by the Lombards before the 8th century as a fortified camp on the slope of the hill where the castle stands. The original name was ''Campus vassorum'', suggesting that the city was the seat of the vassals of the duke of Spoleto. After the Norman conquest of Southern Italy, Campobasso lost its importance as a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman mathematician recorded by history was Hypati ...

19th-century Italian Mathematicians
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Law Of Sines
In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles. According to the law, \frac \,=\, \frac \,=\, \frac \,=\, 2R, where , and are the lengths of the sides of a triangle, and , and are the opposite angles (see figure 2), while is the radius of the triangle's circumcircle. When the last part of the equation is not used, the law is sometimes stated using the reciprocals; \frac \,=\, \frac \,=\, \frac. The law of sines can be used to compute the remaining sides of a triangle when two angles and a side are known—a technique known as triangulation. It can also be used when two sides and one of the non-enclosed angles are known. In some such cases, the triangle is not uniquely determined by this data (called the ''ambiguous case'') and the technique gives two possible values for the enclosed angle. The law of sines is one of two trigonometric equations commonly a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Turin
The University of Turin (Italian: ''Università degli Studi di Torino'', UNITO) is a public research university in the city of Turin, in the Piedmont region of Italy. It is one of the oldest universities in Europe and continues to play an important role in research and training. It is steadily ranked among the top 5 Italian universities and it is ranked third for research activities in Italy, according to the latest data by ANVUR. History Overview The University of Turin was founded as a ''studium'' in 1404, under the initiative of Prince Ludovico di Savoia. From 1427 to 1436 the seat of the university was transferred to Chieri and Savigliano. It was closed in 1536 and reestablished by Duke Emmanuel Philibert thirty years later. It started to gain its modern shape following the model of the University of Bologna, although significant development did not occur until the reforms made by Victor Amadeus II, who also created the Collegio delle Province for students not nativ ...

Geometry
Geometry (; ) is, with arithmetic, one of the oldest branches of mathematics. It is concerned with properties of space such as the distance, shape, size, and relative position of figures. A mathematician who works in the field of geometry is called a ''geometer''. Until the 19th century, geometry was almost exclusively devoted to Euclidean geometry, which includes the notions of point, line, plane, distance, angle, surface, and curve, as fundamental concepts. During the 19th century several discoveries enlarged dramatically the scope of geometry. One of the oldest such discoveries is Carl Friedrich Gauss' ("remarkable theorem") that asserts roughly that the Gaussian curvature of a surface is independent from any specific embedding in a Euclidean space. This implies that surfaces can be studied ''intrinsically'', that is, as stand-alone spaces, and has been expanded into the theory of manifolds and Riemannian geometry. Later in the 19th century, it appeared that geometries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kingdom Of The Two Sicilies
The Kingdom of the Two Sicilies ( it, Regno delle Due Sicilie) was a kingdom in Southern Italy from 1816 to 1860. The kingdom was the largest sovereign state by population and size in Italy before Italian unification, comprising Sicily and all of the Italian Peninsula south of the Papal States, which covered most of the area of today's Mezzogiorno. The kingdom was formed when the Kingdom of Sicily merged with the Kingdom of Naples, which was officially also known as the Kingdom of Sicily. Since both kingdoms were named Sicily, they were collectively known as the "Two Sicilies" (''Utraque Sicilia'', literally "both Sicilies"), and the unified kingdom adopted this name. The king of the Two Sicilies was overthrown by Giuseppe Garibaldi in 1860, after which the people voted in a plebiscite to join the Savoyard Kingdom of Sardinia. The annexation of the Kingdom of the Two Sicilies completed the first phase of Italian unification, and the new Kingdom of Italy was proclaimed in 1 ...

Corrado Segre
Corrado Segre (20 August 1863 – 18 May 1924) was an Italian mathematician who is remembered today as a major contributor to the early development of algebraic geometry. Early life Corrado's parents were Abramo Segre and Estella De Benedetti. Career Segre developed his entire career at the University of Turin, first as a student of Enrico D'Ovidio. In 1883 he published a dissertation on quadrics in projective space and was named as assistant to professors in algebra and analytic geometry. In 1885 he also assisted in descriptive geometry. He began to instruct in projective geometry, as stand-in for Giuseppe Bruno, from 1885 to 1888. Then for 36 years he had the chair in higher geometry following D'Ovidio. Segre and Giuseppe Peano made Turin known in geometry, and their complementary instruction has been noted as follows: The Erlangen program of Felix Klein appealed early on to Segre, and he became a promulgator. First, in 1885 he published an article on conics in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
