Rheticus
Georg Joachim de Porris, also known as Rheticus ( /ˈrɛtɪkəs/; 16 February 1514 – 5 December 1576), was a mathematician, astronomer, cartographer, navigational-instrument maker, medical practitioner, and teacher. He is perhaps best known for his trigonometric tables and as Nicolaus Copernicus's sole pupil.Danielson, p. 3. He facilitated the publication of his master's ''De revolutionibus orbium coelestium'' (''On the Revolutions of the Heavenly Spheres''). Surname Rheticus was born at Feldkirch in the Archduchy of Austria. Both his parents, Georg Iserin and Thomasina de Porris, were of Italian heritage and possessed considerable wealth, his father being the town physician as well as a government official. He was educated by his father until the age of 14 when Georg (Iserin) abused the trust of many of his patients, stealing belongings and money from their homes. In 1528 he was convicted and executed for his crimes, and as a result his family was stripped of their surname. The ... [...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] |
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] |
Achilles Gasser
Achilles Pirmin Gasser (3 November 1505 – 4 December 1577) was a German physician and astrologer. He is now known as a well-connected humanistic scholar, and supporter of both Copernicus and Rheticus. Life Born in Lindau, he studied mathematics, history and philosophy as well as astronomy. He was a student in Sélestat under Johannes Sapidus; he also attended universities in Wittenberg, Vienna, Montpellier, and Avignon.. In 1528, German cartographer Sebastian Münster appealed to scientists across the Holy Roman Empire to assist him with his description of Germany. Gassar accepted this and was later recognized by Münster as a close collaborator for his cartography of the country. Rheticus lost his physician father Georg Iserin in 1528, executed on sorcery charges. Gasser later took over the practice in Feldkirch, Vorarlberg, Feldkirch, in 1538; he taught Rheticus some astrology, and helped his education, in particular by writing to the University of Wittenberg on his behalf. ...

Caspar Peucer

Valentinus Otho
Valentinus Otho (also Valentin Otto; born around 1545–46 possibly in Magdeburg – 8 April 1603 in Heidelberg) was a German mathematician and astronomer. Life In 1573 he came to Wittenberg, proposing to Johannes Praetorius an approximation of pi as \pi \approx \tfrac (now known as ''milü Milü (; "close ratio"), also known as Zulü ( Zu's ratio), is the name given to an approximation to (pi) found by Chinese mathematician and astronomer Zu Chongzhi in the 5th century. Using Liu Hui's algorithm (which is based on the areas of r ...'', as named by its first discover, the Chinese mathematician Zu Chongzhi). In 1575 he supported Georg Joachim Rheticus in his trigonometric tables. The next year they went to Kaschau in Hungary where Rheticus died. Thus, Otho inherited the De revolutionibus manuscript of Nicolaus Copernicus that Rheticus had published in 1543 in Nuremberg.

Feldkirch, Vorarlberg
Feldkirch () is a medieval town in the western Austrian state of Vorarlberg, bordering on Switzerland and Liechtenstein. It is the administrative centre of the Feldkirch district.

Rhaeticus (crater)
Rhaeticus is a lunar impact crater that lies astride the equator of the Moon, on the southeast edge of the Sinus Medii. To the north-northwest is the crater Triesnecker, and due south can be found the worn remnant of the walled plain Hipparchus. The crater was named after Austrian astronomer Georg Joachim Rheticus.''Autostar Suite Astronomer Edition''. CD-ROM. Meade, April 2006. Description The outer wall of Rhaeticus is heavily disintegrated, with rifts and notches in the northeast. The wall is most intact along the eastern face, while in the northwest it is little more than a low rise in the surface. There is also a low cut in the south-southeast wall. The overall shape of the rim is that of a rough hexagon that is slightly elongated in the north–south direction. The interior has been resurfaced by lava, and only a few low rises remain in the surface. Beginning at the crest of the eastern wall is a chain of craterlets that continue to the east-northeast for about a crater dia ...

Habsburg Monarchy
The Habsburg monarchy (german: Habsburgermonarchie, ), also known as the Danubian monarchy (german: Donaumonarchie, ), or Habsburg Empire (german: Habsburgerreich, ), was the collection of empires, kingdoms, duchies, counties and other polities that were ruled by the House of Habsburg, especially the dynasty's Austrian branch. The history of the Habsburg monarchy can be traced back to the election of Rudolf I as King of Germany in 1273 and his acquisition of the Duchy of Austria for the Habsburg in 1282. In 1482, Maximilian I acquired the Netherlands through marriage. Both realms passed to his grandson and successor, Charles V, who also inherited the Spanish throne and its colonial possessions, and thus came to rule the Habsburg empire at its greatest territorial extent. The abdication of Charles V in 1556 led to a division within the dynasty between his son Philip II of Spain and his brother Ferdinand I, who had served as his lieutenant and the elected king of Hungary and ...

Holy Roman Empire
The Holy Roman Empire was a Polity, political entity in Western Europe, Western, Central Europe, Central, and Southern Europe that developed during the Early Middle Ages and continued until its Dissolution of the Holy Roman Empire, dissolution in 1806 during the Napoleonic Wars. From the accession of Otto I in 962 until the twelfth century, the Empire was the most powerful monarchy in Europe. Andrew Holt characterizes it as "perhaps the most powerful European state of the Middle Ages". The functioning of government depended on the harmonic cooperation (dubbed ''consensual rulership'' by Bernd Schneidmüller) between monarch and vassals but this harmony was disturbed during the Salian Dynasty, Salian period. The empire reached the apex of territorial expansion and power under the House of Hohenstaufen in the mid-thirteenth century, but overextending led to partial collapse. On 25 December 800, Pope Leo III crowned the List of Frankish kings, Frankish king Charlemagne as Carolingi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
