Franco Of Liège
Franco of Liège (died ) was an 11th-century mathematician who worked on squaring the circle. He was the chancellor (attested 1057) and later scholaster of Saint Lambert's Cathedral, Liège (before 1066-after 1083). F.P.C. De Jong, "A Comparative Study of Schoolmasters in Eleventh Century Normandy and the Southern Low Countries", Ph.D. thesis, 2018 His ''De quadratura circuli'', explaining his efforts to square the circle, was written around 1050. The musical treatise ''Quaestiones in musica'', primarily ascribed to Rudolf of St Trond, has also been attributed to him. Sigebert of Gembloux ascribes to him other works, including some saints' lives, a poem (ligno crucis) and a treatise on the ember days (De Jejunio IIIIor temporum). Cosmas of Prague Cosmas of Prague (; ; – 21 October 1125) was a Czech priest, writer and historian. Life Between 1075 and 1081, he studied in Liège.

Squaring The Circle
Squaring the circle is a problem in geometry first proposed in Greek mathematics. It is the challenge of constructing a square (geometry), square with the area of a circle, area of a given circle by using only a finite number of steps with a compass and straightedge. The difficulty of the problem raised the question of whether specified axioms of Euclidean geometry concerning the existence of Line (geometry), lines and circles implied the existence of such a square. In 1882, the task was proven to be impossible, as a consequence of the Lindemann–Weierstrass theorem, which proves that pi (\pi) is a transcendental number. That is, \pi is not the zero of a function, root of any polynomial with Rational number, rational coefficients. It had been known for decades that the construction would be impossible if \pi were transcendental, but that fact was not proven until 1882. Approximate constructions with any given non-perfect accuracy exist, and many such constructions have been f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scholaster
A scholaster, from the Latin ''scholasticus'' (schoolmaster), or magister scholarum, was the head of an ecclesiastical school, typically a cathedral school, monastic school, or the school of a collegiate church, in medieval and early-modern Europe.Peter Nissen and William den Boer, "The Middle Ages after 1200", in ''Handbook of Dutch Church History'', edited by Herman Selderhuis (Göttingen, 2014), pp. 141–142. Depending on the size of the school and the status of the institution to which it was attached, the scholaster might be the only teacher, the head of a considerable educational establishment, or have oversight over all the schools in their city or territory. The scholaster might be a dignitary in a cathedral or collegiate chapter, alongside the provost, dean, cantor, succentor, precentor, archdeacon, treasurer, cellarer, sacristan or almoner An almoner () is a chaplain or church officer who originally was in charge of distributing money to the deserving poor.

Saint Lambert's Cathedral, Liège
St. Lambert's Cathedral (or in full, the Cathedral of Our Lady and St. Lambert; ) was the Catholic Church, Roman Catholic cathedral of Liège, modern-day Belgium, until 1794, when its destruction began. This enormous Gothic architecture, Gothic cathedral, dedicated to Saint Lambert of Maastricht, occupied the site of the present Place Saint-Lambert in the centre of Liège. History Saint Lambert, bishop of Maastricht, was assassinated in Liège about 705, and was initially buried in Maastricht. The site of his martyrdom became a place of pilgrimage, and his successor, Saint Hubert, returned the body and reburied it there. Shortly afterwards, the bishop's seat was transferred from Maastricht to Liège, and Lambert's shrine became a cathedral. Several structures succeeded each other on the site. The first was a martyr's shrine or mausoleum (''martyrium''), commissioned by Saint Hubert. Unusually, it was oriented to the west, which may account for the existence of a west choir ...

Rudolf Of St Trond
Rudolf of St Trond (also Rodulf, Rodolfus, Rodolphe, Radulphus, Rudolph, or Raoul, c. 1070–1138) was a Benedictine abbot of St Trond Abbey, chronicler and composer. A musical treatise ''Quaestiones in musica'' was attributed to him by the musicologist Rudolf Steglich; another suggestion is Franco of Liège. He wrote a chronicle ''Gesta Abbatum Trudonensium'', on the abbots of his abbey, beginning in 999; it is included in the '' Paleographie musicale'' and the ''Monumenta Germaniae Historica''. His description of monastic life includes details of musical practice and training methods of Guido of Arezzo. Historian Henri de Lubac Henri-Marie Joseph Sonier de Lubac (; 20 February 1896 – 4 September 1991), better known as Henri de Lubac, was a French Jesuit priest and Cardinal (Catholicism), cardinal who is considered one of the most influential Theology, theologia ... wrote that he showed "a very exacting and almost combative idea of historical truth."''Medieval Exeges ...

Sigebert Of Gembloux
Sigebert or Sigibert of Gembloux ( or ; – 5 October 1112) was a medieval author, known mainly as a pro-Imperial historian of a universal chronicle, opposed to the expansive papacy of Gregory VII and Pascal II. Early in his life he became a monk in the Benedictine abbey of Gembloux. Life He was born near Gembloux which is now in the Province of Namur, Belgium, about 1030. He was apparently not of Germanic background, but seems to have been of Latin descent. He received his education at the Abbey of Gembloux, where at an early age he became a monk. Later he was for a long time a teacher at the Abbey of St. Vincent at Metz; about 1070 he returned to Gembloux. He was universally admired, and had charge there of the abbey school until his death, occupied in teaching and writing.Löffler, Klem ...

Cosmas Of Prague
Cosmas of Prague (; ; – 21 October 1125) was a Czech priest, writer and historian. Life Between 1075 and 1081, he studied in Liège. After his return to Bohemia, he married Božetěcha with whom he had a son, named Jindřich Zdík, and remained in minor orders. His son later became Bishop of Olomouc. In 1094, he was ordained a deacon, and in 1099, he was ordained a priest at Esztergom, Hungary. Works His ''magnum opus,'' written in Latin, is called '' Chronica Boemorum''. The ''Chronica'' is divided into three books: *The first book, completed in 1119, starts with the creation of the world and ends in the year 1038. It describes the legendary foundation of the Bohemian state by the oldest Bohemians around the year 600 (Duke Czech, Duke Krok and his three daughters), Duchess Libuše and the foundation of Přemyslid dynasty by her marriage with Přemysl, old bloody wars, Duke Bořivoj and the introduction of Christianity in Bohemia, Saint Wenceslaus and his grandmother ...

11th-century Births
The 11th century is the period from 1001 (represented by the Roman numerals MI) through 1100 (MC) in accordance with the Julian calendar, and the 1st century of the 2nd millennium. In the history of Europe, this period is considered the early part of the High Middle Ages. There was, after a brief ascendancy, a sudden decline of Byzantine power and a rise of Norman domination over much of Europe, along with the prominent role in Europe of notably influential popes. Christendom experienced a formal schism in this century which had been developing over previous centuries between the Latin West and Byzantine East, causing a split in its two largest denominations to this day: Roman Catholicism and Eastern Orthodoxy. In Song dynasty China and the classical Islamic world, this century marked the high point for both classical Chinese civilization, science and technology, and classical Islamic science, philosophy, technology and literature. Rival political factions at the Song dynast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1080s Deaths
1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientists From Liège
A scientist is a person who researches to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From The Prince-Bishopric Of Liège
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
