Maestlin
Michael Maestlin (also Mästlin, Möstlin, or Moestlin) (30 September 1550 – 26 October 1631) was a German astronomer and mathematician, known for being the mentor of Johannes Kepler. He was a student of Philipp Apian and was known as the teacher who most influenced Kepler. Maestlin was considered to be one of the most significant astronomers between the time of Copernicus and Kepler. Early life and family Maestlin was born on September 30, 1550 in Göppingen, a small town in Southern Germany, about 50 kilometers east of Tübingen. The son of Jakob Maestlin and Dorothea Simon, Michael Maestlin was born into a Protestant family. Maestlin had an older sister named Elisabeth and a younger brother named Matthäus. The original family name of the Maestlin was Leckher or Legecker and they lived in the village of Boll, just a few kilometers south of Göppingen (Decker 103). In his autobiography, Maestlin recounts how the family name of Legecker became Mästlin. He claims that one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johannes Kepler
Johannes Kepler (; ; 27 December 1571 – 15 November 1630) was a German astronomer, mathematician, astrologer, natural philosopher and writer on music. He is a key figure in the 17th-century Scientific Revolution, best known for his laws of planetary motion, and his books ''Astronomia nova'', ''Harmonice Mundi'', and ''Epitome Astronomiae Copernicanae''. These works also provided one of the foundations for Newton's theory of universal gravitation. Kepler was a mathematics teacher at a seminary school in Graz, where he became an associate of Prince Hans Ulrich von Eggenberg. Later he became an assistant to the astronomer Tycho Brahe in Prague, and eventually the imperial mathematician to Emperor Rudolf II and his two successors Matthias and Ferdinand II. He also taught mathematics in Linz, and was an adviser to General Wallenstein. Additionally, he did fundamental work in the field of optics, invented an improved version of the refracting (or Keplerian) telescope, an ...

De Revolutionibus Orbium Coelestium
''De revolutionibus orbium coelestium'' (English translation: ''On the Revolutions of the Heavenly Spheres'') is the seminal work on the heliocentric theory of the astronomer Nicolaus Copernicus (1473–1543) of the Polish Renaissance. The book, first printed in 1543 in Nuremberg, Holy Roman Empire, offered an alternative model of the universe to Ptolemy's geocentric system, which had been widely accepted since ancient times. History Copernicus initially outlined his system in a short, untitled, anonymous manuscript that he distributed to several friends, referred to as the ''Commentariolus''. A physician's library list dating to 1514 includes a manuscript whose description matches the ''Commentariolus'', so Copernicus must have begun work on his new system by that time. Most historians believe that he wrote the ''Commentariolus'' after his return from Italy, possibly only after 1510. At this time, Copernicus anticipated that he could reconcile the motion of the Earth with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden Ratio
In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities. Expressed algebraically, for quantities a and b with a > b > 0, where the Greek letter phi ( or \phi) denotes the golden ratio. The constant \varphi satisfies the quadratic equation \varphi^2 = \varphi + 1 and is an irrational number with a value of The golden ratio was called the extreme and mean ratio by Euclid, and the divine proportion by Luca Pacioli, and also goes by several other names. Mathematicians have studied the golden ratio's properties since antiquity. It is the ratio of a regular pentagon's diagonal to its side and thus appears in the construction of the dodecahedron and icosahedron. A golden rectangle—that is, a rectangle with an aspect ratio of \varphi—may be cut into a square and a smaller rectangle with the same aspect ratio. The golden ratio has been used to analyze the proportions of natural object ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicolaus Copernicus
Nicolaus Copernicus (; pl, MikoÅ‚aj Kopernik; gml, Niklas Koppernigk, german: Nikolaus Kopernikus; 19 February 1473 – 24 May 1543) was a Renaissance polymath, active as a mathematician, astronomer, and Catholic Church, Catholic canon (priest), canon, who formulated a mathematical model, model of Celestial spheres#Renaissance, the universe that placed heliocentrism, the Sun rather than Earth at its center. In all likelihood, Copernicus developed his model independently of Aristarchus of Samos, an ancient Greek astronomer who had formulated such a model some eighteen centuries earlier. The publication of Copernicus's model in his book ' (''On the Revolutions of the Celestial Spheres''), just before his death in 1543, was a major event in the history of science, triggering the Copernican Revolution and making a pioneering contribution to the Scientific Revolution. Copernicus was born and died in Royal Prussia, a region that had been part of the Kingdom of Poland (1385â ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christian Wursteisen
Christian Wurstisen ( la, Christianus Urstisius) (23 December 1544 – 29 March 1588) was a mathematician, theologician, historian from Basel. His name is also given as ''Wursteisen, Wurzticius, Ursticius, Urstisius'', or ''Urstis''. Life In 1565, he became professor of mathematics at the Basel University, and in 1585 professor of theology. The next year, the city magistrate appointed him to the academy as a town historian, a position he held until his death. He was buried in Münster. The second edition of Nicolaus Copernicus's De revolutionibus orbium coelestium had been printed in Basel. Wurstisen is credited to have first introduced Copernicus' work to Galileo Galilei, while Galilei's adoption of heliocentrism was often attributed to Michael Maestlin. Christian Wurstisen is mentioned by name in Galileo's ''Dialogue''. This attribution has been challenged, however, and another similarly named man, Christopher Wursteisen, has been credited with introducing Copernicus's the ...

Tübinger Stift
The Tübinger Stift () is a hall of residence and teaching; it is owned and supported by the Evangelical-Lutheran Church in Württemberg, and located in the university city of Tübingen, in South West Germany. The Stift was founded as an Augustinian monastery in the Middle Ages. After the Reformation, in 1536, Duke Ulrich turned the Stift into a seminary which served to prepare Protestant pastors for Württemberg. To this day the scholarship is still given to students in preparation for the ministry or teaching in Baden-Württemberg. Students receive a scholarship which consists of boarding, lodging and further academic support. Some of the well known "Stiftlers" are the astronomer Johannes Kepler and his associate, statesman Hans Ulrich von Eggenberg, the poet Friedrich Hölderlin who had as roommates the philosophers G. W. F. Hegel and Friedrich Schelling (although the latter was five years their junior), the theologians David Friedrich Strauß, Johann Albrecht Bengel, Friedri ...

Göppingen
Göppingen ( Swabian: ''Geppenge'' or ''Gebbenga'') is a town in southern Germany, part of the Stuttgart Region of Baden-Württemberg. It is the capital of the district Göppingen. Göppingen is home to the toy company Märklin, and it is the birthplace of football player Jürgen Klinsmann. It also hosts the headquarters of TeamViewer AG - the main sponsors of Manchester United. Geography Göppingen is situated at the bottom of the Hohenstaufen mountain, in the valley of the river Fils. The districts of Göppingen are Bartenbach, Bezgenriet, Faurndau, Göppingen, Hohenstaufen, Holzheim, Jebenhausen and Maitis. History Tradition holds that the city was founded by an Alemannic leader called Geppo sometime in the 3rd or 4th century. A disastrous fire on August 25, 1782 destroyed most of the town, but it was immediately rebuilt. Industrialisation during the 19th century made the area into a centre of industry. The importance of such industry is still seen in the town in the pres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protestantism
Protestantism is a branch of Christianity that follows the theological tenets of the Protestant Reformation, a movement that began seeking to reform the Catholic Church from within in the 16th century against what its followers perceived to be growing errors, abuses, and discrepancies within it. Protestantism emphasizes the Christian believer's justification by God in faith alone (') rather than by a combination of faith with good works as in Catholicism; the teaching that salvation comes by divine grace or "unmerited favor" only ('); the priesthood of all faithful believers in the Church; and the ''sola scriptura'' ("scripture alone") that posits the Bible as the sole infallible source of authority for Christian faith and practice. Most Protestants, with the exception of Anglo-Papalism, reject the Catholic doctrine of papal supremacy, but disagree among themselves regarding the number of sacraments, the real presence of Christ in the Eucharist, and matters of ecclesiast ...

Backnang
Backnang (; swg, Bagene) is a town in Germany in the Bundesland of Baden-Württemberg, roughly northeast of Stuttgart. Its population has increased greatly over the past century, from 7,650 in 1900 to 35,761 in 2005. Backnang was ceded to Württemberg by the Baden ( Zähringer family) in 1325. Backnang has been known as ''Gerberstadt'' due to several tanneries and leather factories, and wool and cloth mills that dominated Backnang's industries. Today, all of these have vanished, and instead, telecommunication companies such as Ericsson (formerly AEG, Telefunken, ANT Nachrichtentechnik, Bosch and Marconi) and Tesat-Spacecom dominate the town's industries. The ''Stiftskirche'', formerly the church of Backnang Abbey, dates back to the 12th century. Backnang hosts the annual ''Strassenfest'' during the last weekend in June. It has been founded as a street festival where local sports and cultural clubs offered drinks and foods. The traditional opening of the ''Strassenfest'' ...

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 ...

Copernican Heliocentrism
Copernican heliocentrism is the astronomical model developed by Nicolaus Copernicus and published in 1543. This model positioned the Sun at the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular paths, modified by epicycles, and at uniform speeds. The Copernican model displaced the geocentric model of Ptolemy that had prevailed for centuries, which had placed Earth at the center of the Universe. Although he had circulated an outline of his own heliocentric theory to colleagues sometime before 1514, he did not decide to publish it until he was urged to do so later by his pupil Rheticus. Copernicus's challenge was to present a practical alternative to the Ptolemaic model by more elegantly and accurately determining the length of a solar year while preserving the metaphysical implications of a mathematically ordered cosmos. Thus, his heliocentric model retained several of the Ptolemaic elements, causing inaccuracies, such as the pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
