Francesco Faà Di Bruno
Francesco Faà di Bruno (7 March 1825 – 25 March 1888) was an Italian priest and advocate of the poor, a leading mathematician of his era and a noted religious musician. In 1988 he was beatified by Pope John Paul II.See the Vatican News Service, "''Papal Office for Liturgical Celebrations''" . He is the eponym of Faà di Bruno's formula. Life Early life Faà di Bruno was born in Alessandria, then part of the Kingdom of Sardinia, on 7 March 1825. He was of noble birth, being the twelfth and youngest child of the Marchese Luigi Faà di Bruno and the Lady Carolina Sappa de' Milanesi. He was raised in a home marked by happiness, the arts and a concern for the poor arising from the parents' strong Catholic faith. As a young man, he entered the Royal Army and held, at one time, the rank of Staff Officer. He resigned his commission, and went to Paris, where he did doctoral studies in mathematics under Augustin Cauchy, and Urbain Le Verrier, who both shared in the discovery of the p ...

Alessandria
Alessandria (; pms, Lissandria ) is a city and ''comune'' in Piedmont, Italy, and the capital of the Province of Alessandria. The city is sited on the alluvial plain between the Tanaro and the Bormida rivers, about east of Turin. Alessandria is also a major railway hub. History Alessandria was founded in 1168 with a charter as a free comune; it was sited upon a preexisting urban nucleus, to serve as a stronghold for the Lombard League, defending the traditional liberties of the communes of northern Italy against the Imperial forces of Frederick Barbarossa. Alessandria stood in the territories of the marchese of Montferrat, a staunch ally of the Emperor, with a name assumed in 1168 to honour the Emperor's opponent, Pope Alexander III. In 1174–1175 the fortress was sorely tested by the Imperial siege and stood fast. A legend (related in Umberto Eco's book ''Baudolino'', and which recalls one concerning Bishop Herculanus’ successful defence of Perugia several centuries ear ...

Combinatorics
Combinatorics is an area of mathematics primarily concerned with counting, both as a means and an end in obtaining results, and certain properties of finite structures. It is closely related to many other areas of mathematics and has many applications ranging from logic to statistical physics and from evolutionary biology to computer science. Combinatorics is well known for the breadth of the problems it tackles. Combinatorial problems arise in many areas of pure mathematics, notably in algebra, probability theory, topology, and geometry, as well as in its many application areas. Many combinatorial questions have historically been considered in isolation, giving an ''ad hoc'' solution to a problem arising in some mathematical context. In the later twentieth century, however, powerful and general theoretical methods were developed, making combinatorics into an independent branch of mathematics in its own right. One of the oldest and most accessible parts of combinatorics is gra ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Urbain Le Verrier
Urbain Jean Joseph Le Verrier FRS (FOR) HFRSE (; 11 March 1811 – 23 September 1877) was a French astronomer and mathematician who specialized in celestial mechanics and is best known for predicting the existence and position of Neptune using only mathematics. The calculations were made to explain discrepancies with Uranus's orbit and the laws of Kepler and Newton. Le Verrier sent the coordinates to Johann Gottfried Galle in Berlin, asking him to verify. Galle found Neptune in the same night he received Le Verrier's letter, within 1° of the predicted position. The discovery of Neptune is widely regarded as a dramatic validation of celestial mechanics, and is one of the most remarkable moments of 19th-century science. Biography Early years Le Verrier was born at Saint-Lô, Manche, France, in a modest bourgeois family, his parents being, Louis-Baptiste Le Verrier and Marie-Jeanne-Josephine-Pauline de Baudre. He studied at École Polytechnique. He briefly studied chemistry und ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Augustin Cauchy
Baron Augustin-Louis Cauchy (, ; ; 21 August 178923 May 1857) was a French mathematician, engineer, and physicist who made pioneering contributions to several branches of mathematics, including mathematical analysis and continuum mechanics. He was one of the first to state and rigorously prove theorems of calculus, rejecting the heuristic principle of the generality of algebra of earlier authors. He almost singlehandedly founded complex analysis and the study of permutation groups in abstract algebra. A profound mathematician, Cauchy had a great influence over his contemporaries and successors; Hans Freudenthal stated: "More concepts and theorems have been named for Cauchy than for any other mathematician (in elasticity alone there are sixteen concepts and theorems named for Cauchy)." Cauchy was a prolific writer; he wrote approximately eight hundred research articles and five complete textbooks on a variety of topics in the fields of mathematics and mathematical physics.

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 ...

Staff (military)
A military staff or general staff (also referred to as army staff, navy staff, or air staff within the individual services) is a group of officers, enlisted and civilian staff who serve the commander of a division or other large military unit in their command and control role through planning, analysis, and information gathering, as well as by relaying, coordinating, and supervising the execution of their plans and orders, especially in case of multiple simultaneous and rapidly changing complex operations. They are organised into functional groups such as administration, logistics, operations, intelligence, training, etc. They provide multi-directional flow of information between a commanding officer, subordinate military units and other stakeholders.PK Mallick, 2011Staff System in the Indian Army: Time for Change Centre for Land Warfare Studies, New Delhi, vol 31. A centralised general staff results in tighter top-down control but requires larger staff at headquarters (H ...

Marchese
A marquess (; french: marquis ), es, marqués, pt, marquês. is a nobleman of high hereditary rank in various European peerages and in those of some of their former colonies. The German language equivalent is Markgraf (margrave). A woman with the rank of a marquess or the wife (or widow) of a marquess is a marchioness or marquise. These titles are also used to translate equivalent Asian styles, as in Imperial China and Imperial Japan. Etymology The word ''marquess'' entered the English language from the Old French ("ruler of a border area") in the late 13th or early 14th century. The French word was derived from ("frontier"), itself descended from the Middle Latin ("frontier"), from which the modern English word ''march'' also descends. The distinction between governors of frontier territories and interior territories was made as early as the founding of the Roman Empire when some provinces were set aside for administration by the senate and more unpacified or vulnerable ...

Eponym
An eponym is a person, a place, or a thing after whom or which someone or something is, or is believed to be, named. The adjectives which are derived from the word eponym include ''eponymous'' and ''eponymic''. Usage of the word The term ''eponym'' functions in multiple related ways, all based on an explicit relationship between two named things. A person, place, or thing named after a particular person share an eponymous relationship. In this way, Elizabeth I of England is the eponym of the Elizabethan era. When Henry Ford is referred to as "the ''eponymous'' founder of the Ford Motor Company", his surname "Ford" serves as the eponym. The term also refers to the title character of a fictional work (such as Rocky Balboa of the Rocky film series, ''Rocky'' film series), as well as to ''self-titled'' works named after their creators (such as the album The Doors (album), ''The Doors'' by the band the Doors). Walt Disney created the eponymous The Walt Disney Company, Walt Disney Com ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Beatification
Beatification (from Latin ''beatus'', "blessed" and ''facere'', "to make”) is a recognition accorded by the Catholic Church of a deceased person's entrance into Heaven and capacity to intercede on behalf of individuals who pray in their name. ''Beati'' is the plural form, referring to those who have undergone the process of beatification; they possess the title of "Blessed" (abbreviation "Bl.") before their names and are often referred to in English as "a Blessed" or, plurally, "Blesseds". History Local bishops had the power of beatifying until 1634, when Pope Urban VIII, in the apostolic constitution ''Cœlestis Jerusalem'' of 6 July, reserved the power of beatifying to the Holy See. Since the reforms of 1983, as a rule, one miracle must be confirmed to have taken place through the intercession of the person to be beatified. Miracles are almost always unexplainable medical healings, and are scientifically investigated by commissions comprising physicians and theologia ...

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 ...

Priesthood (Catholic Church)
The priesthood is the office of the ministers of religion, who have been commissioned ("ordained") with the Holy orders of the Catholic Church. Technically, bishops are a priestly order as well; however, in layman's terms ''priest'' refers only to presbyters and pastors (parish priests). The church's doctrine also sometimes refers to all baptised (lay) members as the "common priesthood", which can be confused with the ministerial priesthood of the consecrated clergy. The church has different rules for priests in the Latin Church–the largest Catholic particular church–and in the 23 Eastern Catholic Churches. Notably, priests in the Latin Church must take a vow of celibacy, whereas most Eastern Catholic Churches permit married men to be ordained. Deacons are male and usually belong to the diocesan clergy, but, unlike almost all Latin Church (Western Catholic) priests and all bishops from Eastern or Western Catholicism, they may marry as laymen before their ordination as cler ...
