Orbassano
Orbassano is a ''comune'' (municipality) in the Metropolitan City of Turin in the Italian region Piedmont, located about southwest of Turin. Orbassano borders the following municipalities: Turin, Rivoli, Rivalta di Torino, Beinasco, Nichelino, Volvera, Candiolo, None. History The known origins of the city date back to the Roman conquest of Cisalpine Gaul, evidenced by two Imperial era tombstones found here in the second half of the nineteenth century. By the end of the first millennium, Orbassano was among the lands of the Margrave of Susa, but in 1029 it found itself sold by Manfredi to the new Abbey of San Giusto in Susa. Shortly thereafter, in 1035, some of the land came into the possession of the Diocese of Turin. In the twelfth century Orbassano came under the control of its northern neighbours the Lords of Rivalta, the Orsini family. People Sonia Gandhi was raised here, although she was born in Lusiana, near Vicenza. Twin towns Orbassano is twinned w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Liguria
Liguria (; lij, Ligûria ; french: Ligurie) is a Regions of Italy, region of north-western Italy; its Capital city, capital is Genoa. Its territory is crossed by the Alps and the Apennine Mountains, Apennines Mountain chain, mountain range and is roughly coextensive with the former territory of the Republic of Genoa. Liguria is bordered by France (Provence-Alpes-Côte d'Azur) to the west, Piedmont to the north, and Emilia-Romagna and Tuscany to the east. It rests on the Ligurian Sea, and has a population of 1,557,533. The region is part of the Alps–Mediterranean Euroregion. Etymology The name ''Liguria'' predates Latin and is of obscure origin.

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 ...

Palmiro Togliatti
Palmiro Michele Nicola Togliatti (; 26 March 1893 – 21 August 1964) was an Italian politician and leader of the Italian Communist Party from 1927 until his death. He was nicknamed ("The Best") by his supporters. In 1930 he became a citizen of the Soviet Union and later he had a city in that country named after him: Tolyatti. Togliatti was a founding member of the Communist Party of Italy (''Partito Comunista d’Italia'', PCI), and from 1927 until his death, he was the Secretary and the undisputed leader of the Italian Communist Party, except for the period from 1934 to 1938, during which he served as representative to the Comintern, the international organization of communist parties. After the dissolution of the Comintern in 1943 and the formation of the Cominform in 1947, he refused the post of Secretary General, offered to him directly by Stalin in 1951, preferring to remain at the head of the PCI. From 1944 to 1945 Togliatti held the post of Deputy Prime Minister and from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dionisio Gallarati
Dionisio Gallarati (May 8, 1923 – May 13, 2019) was an Italian mathematician, who specialised in algebraic geometry. He was a major influence on the development of algebra and geometry at the University of Genova. Life Born 8 May 1923 in Savona, Italy, Gallarati joined the University of Pisa in 1941. His studies being interrupted by the war, he received his first degree from Genova.www-history.mcs.st-andrews.ac.uk/Biographies/Gallarati.html He started his research career at l'Istituto Nazionale di Alta Matematica in Rome, where he was taught by Giacomo Albanese, Leonard Roth, Leonida Tonelli, E. G. Togliatti, Beniamino Segre and Francesco Severi. He took a post at Genova in 1947, where he stayed until he retired in 1987. Research Gallarati published 64 papers between 1951 and 1996.

1890 Births
Year 189 ( CLXXXIX) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Silanus and Silanus (or, less frequently, year 942 ''Ab urbe condita''). The denomination 189 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

People From Orbassano
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...
