Jan Å indel
Jan Šindel (1370s – between 1455 and 1457), also known as Jan Ondřejův ( or ''Joannes de Praga''), was a Czechs, Czech medieval scientist and Catholic priest. He was a professor at Charles University in Prague and became the Rector (academia), rector of the university in 1410. He lectured on mathematics and astronomy and was also a personal astrologer and physician of kings Wenceslaus IV of Bohemia and his brother Holy Roman Emperor Sigismund, Holy Roman Emperor, Sigismund. Life Jan Šindel was born in Hradec Králové probably in the 1370s. As a young man he came to Prague to study at Charles University. In 1395 or 1399 he became the Master of Arts at Prague University. In 1406 he worked at the parish school of the St. Nicholas Church (Malá Strana), St. Nicolas Church in Malá Strana in Prague. Later he worked as a teacher of mathematics in Vienna, where he also studied medicine. Then he came back to Prague and became the professor of astronomy at Charles University, where ...

Canon (priest)
A canon (from the Latin , itself derived from the Greek , , "relating to a rule", "regular") is a member of certain bodies in subject to an ecclesiastical rule. Originally, a canon was a cleric living with others in a clergy house or, later, in one of the houses within the precinct of or close to a cathedral or other major church and conducting his life according to the customary discipline or rules of the church. This way of life grew common (and is first documented) in the 8th century AD. In the 11th century, some churches required clergy thus living together to adopt the rule first proposed by Saint Augustine that they renounce private wealth. Those who embraced this change were known as Augustinians or Canons Regular, whilst those who did not were known as secular canons. Secular canons Latin Church In the Latin Church, the members of the chapter of a cathedral (cathedral chapter) or of a collegiate church (so-called after their chapter) are canons.

Å indel Sequence
In additive combinatorics, a Å indel sequence is a periodic sequence of integers with the property that its partial sums include all of the triangular numbers. For instance, the sequence that begins 1, 2, 3, 4, 3, 2 is a Å indel sequence, with the triangular partial sums etc. Another way of describing such a sequence is that it can be partitioned into contiguous subsequences whose sums are the consecutive integers: This particular example is used in the gearing of the Prague astronomical clock, as part of a mechanism for chiming the clock's bells the correct number of times at each hour. The Å indel sequences are named after Jan Å indel, a Czech scientist in the 14th and 15th centuries whose calculations were used in the design of the Prague clock. The definition and name of these sequences were given by Michal KřÞek, Alena Å olcová, and Lawrence Somer, in their work analyzing the mathematics of the Prague clock.

Mikuláš Of Kadaň
Mikuláš of Kadaň ( cs, Mikuláš z Kadaně) (born 1350, Kadaň – died 1419, Prague) was an Imperial clockmaker. The oldest part of the Orloj (which also known as Prague Astronomical Clock), the mechanical clock and astronomical dial, dates back to 1410, was designed by Mikuláš of Kadaň and Jan Šindel The clock was modified by Master Hanuš, who was mistakenly identified as the creator of the clock in a legend related by Alois Jirásek. See also * Astronomical clock An astronomical clock, horologium, or orloj is a clock with special mechanisms and dials to display astronomical information, such as the relative positions of the Sun, Moon, zodiacal constellations, and sometimes major planets.

Tycho Brahe
Tycho Brahe ( ; born Tyge Ottesen Brahe; generally called Tycho (14 December 154624 October 1601) was a Danish astronomer, known for his comprehensive astronomical observations, generally considered to be the most accurate of his time. He was known during his lifetime as an astronomer, astrologer, and alchemist. He was the last major astronomer before the invention of the telescope. An heir to several noble families, Tycho was well-educated. He took an interest in astronomy and in the creation of more accurate instruments of measurement. He worked to combine what he saw as the geometrical benefits of Copernican heliocentrism with the philosophical benefits of the Ptolemaic system, and devised the Tychonic system, his own version of a model of the universe, with the Sun orbiting the Earth, and the planets as orbiting the Sun. In ''De nova stella'' (1573), he refuted the Aristotelian belief in an unchanging celestial realm. His measurements indicated that "new stars" (''stellae ...

Pope Pius II
Pope Pius II ( la, Pius PP. II, it, Pio II), born Enea Silvio Bartolomeo Piccolomini ( la, Aeneas Silvius Bartholomeus, links=no; 18 October 1405 – 14 August 1464), was head of the Catholic Church and ruler of the Papal States from 19 August 1458 to his death in August 1464. He was born at Corsignano in the Sienese territory of a noble but impoverished family. He was a Renaissance humanist, famous as an author in Latin before he became pope. His longest and most enduring work is the story of his life, the ''Commentaries'', which is the only revealed autobiography ever to have been written by a reigning pope. This was only published in 1584. Early life Aeneas was born to Silvio, a soldier and member of the House of Piccolomini, and Vittoria Forteguerri, who had 18 children including several twins, though most died at a young age. He worked with his father in the fields for some years and at age 18 left to study at the universities of Siena and Florence. He settled in the f ...

Dean (Christianity)
A dean, in an ecclesiastical context, is a cleric holding certain positions of authority within a religious hierarchy. The title is used mainly in the Roman Catholic Church, the Anglican Communion, and many Lutheran denominations. A dean's assistant is called a sub-dean. History Latin ''decanus'' in the Roman military was the head of a group of ten soldiers within a '' centuria'', and by the 5th century CE, it was the head of a group of ten monks. It came to refer to various civil functionaries in the later Roman Empire.''Oxford English Dictionary'' s.v.' Based on the monastic use, it came to mean the head of a chapter of canons of a collegiate church or cathedral church. Based on that use, deans in universities now fill various administrative positions. Latin ''decanus'' should not be confused with Greek ''diákonos'' (διάκονος),' from which the word deacon derives, which describes a supportive role. Officials In the Roman Catholic Church, the Dean of the Colleg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuremberg
