Rudolphine Tables
The ''Rudolphine Tables'' ( la, Tabulae Rudolphinae) consist of a star catalogue and planetary tables published by Johannes Kepler in 1627, using observational data collected by Tycho Brahe (1546–1601). The tables are named in memory of Rudolf II, Holy Roman Emperor, in whose employ Brahe and Kepler had begun work on the tables. The main purpose of the Rudolphine tables was to allow the computation of the positions of the then known planets of the Solar System, and they were considerably more precise than earlier such tables. Previous tables Star tables had been produced for many centuries and were used to establish the position of the planets relative to the fixed stars (particularly the twelve constellations used in astrology) on a specific date in order to construct horoscopes. Until the end of the 16th century, the most widely used had been the '' Alphonsine tables'', first produced in the 13th century and regularly updated thereafter. These were based on a Ptolemaic, geoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peasants' War In Upper Austria
The Peasants' War in Upper Austria (german: Oberösterreichischer Bauernkrieg) was a rebellion led by farmers in 1626 whose goal was to free Upper Austria from Bavarian rule. The motive (found in the of 1625) was an escalation of the Bavarian Electorate's attempt to press the country into the Catholic faith at the time of the Thirty Years' War. History In the beginning of the Thirty Years' War, Upper Austria was pledged to the Bavarian Electorate by the House of Habsburg. The new ruler assumed ''cuius regio, eius religio'' (the religion of the ruler dictated the religion of the ruled) and tried to convert the lands to the Catholic faith. In May 1625, the Protestant priest of the Frankenburg am Hausruck parish was replaced by a Catholic priest sent from Bavaria. After an armed uprising, the new priest was forced to flee from the castle. However, the men feared the reaction from Bavaria and surrendered three days later. Adam von Herberstorff, the Bavarian steward of Upper Austri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thirty Years' War
The Thirty Years' War was one of the longest and most destructive conflicts in European history The history of Europe is traditionally divided into four time periods: prehistoric Europe (prior to about 800 BC), classical antiquity (800 BC to AD 500), the Middle Ages (AD 500 to AD 1500), and the modern era (since AD 1500). The first early ..., lasting from 1618 to 1648. Fought primarily in Central Europe, an estimated 4.5 to 8 million soldiers and civilians died as a result of battle, famine, and disease, while some areas of what is now modern Germany experienced population declines of over 50%. Related conflicts include the Eighty Years' War, the War of the Mantuan Succession, the Franco-Spanish War (1635–1659), Franco-Spanish War, and the Portuguese Restoration War. Until the 20th century, historians generally viewed it as a continuation of the religious struggle initiated by the 16th-century Reformation within the Holy Roman Empire.

Linz
Linz ( , ; cs, Linec) is the capital of Upper Austria and third-largest city in Austria. In the north of the country, it is on the Danube south of the Czech border. In 2018, the population was 204,846. In 2009, it was a European Capital of Culture. Geography Linz is in the centre of Europe, lying on the Paris–Budapest west–east axis and the Malmö–Trieste north–south axis. The Danube is the main tourism and transport connection that runs through the city. Approximately 29.27% of the city's wide area is grassland. A further 17.95% are covered with forest. All the rest areas fall on water (6.39%), traffic areas and land. Districts Since January 2014 the city has been divided into 16 statistical districts: Before 2014 Linz was divided into nine districts and 36 statistical quarters. They were: #Ebelsberg #Innenstadt: Altstadtviertel, Rathausviertel, Kaplanhofviertel, Neustadtviertel, Volksgartenviertel, Römerberg-Margarethen #Kleinmünchen: Kleinmünchen, Neue ...

Florin
The Florentine florin was a gold coin struck from 1252 to 1533 with no significant change in its design or metal content standard during that time. It had 54 grains (3.499 grams, 0.113 troy ounce) of nominally pure or 'fine' gold with a purchasing power difficult to estimate (and variable) but ranging according to social grouping and perspective from approximately 140 to 1,000 modern US dollars. The name of the coin comes from the ''Giglio bottonato'' ( it), the floral emblem of the city, which is represented at the head of the coin. History The ''fiorino d'oro'' (gold florin) was used in the Republic of Florence and was the first European gold coin struck in sufficient quantities since the 7th century to play a significant commercial role. The florin was recognized across large parts of Europe. The territorial usage of the '' lira'' and the florin often overlapped, where the lira was used for smaller transactions (wages, food purchases), the florin was for larger transactions ...

Jesuits In China
The history of the missions of the Jesuits in China is part of the history of relations between China and the Western world. The missionary efforts and other work of the Society of Jesus, or Jesuits, between the 16th and 17th century played a significant role in continuing the transmission of knowledge, science, and culture between China and the West, and influenced Christian culture in Chinese society today. The first attempt by the Jesuits to reach China was made in 1552 by St. Francis Xavier, Navarrese priest and missionary and founding member of the Society of Jesus. Xavier never reached the mainland, dying after only a year on the Chinese island of Shangchuan. Three decades later, in 1582, Jesuits once again initiated mission work in China, led by several figures including the Italian Matteo Ricci, introducing Western science, mathematics, astronomy, and visual arts to the Chinese imperial court, and carrying on significant inter-cultural and philosophical dialogue with ...

Mughal India
The Mughal Empire was an early-modern empire that controlled much of South Asia between the 16th and 19th centuries. Quote: "Although the first two Timurid emperors and many of their noblemen were recent migrants to the subcontinent, the dynasty and the empire itself became indisputably Indian. The interests and futures of all concerned were in India, not in ancestral homelands in the Middle East or Central Asia. Furthermore, the Mughal empire emerged from the Indian historical experience. It was the end product of a millennium of Muslim conquest, colonization, and state-building in the Indian subcontinent." For some two hundred years, the empire stretched from the outer fringes of the Indus river basin in the west, northern Afghanistan in the northwest, and Kashmir in the north, to the highlands of present-day Assam and Bangladesh in the east, and the uplands of the Deccan Plateau in South India. Quote: "The realm so defined and governed was a vast territory of some , rang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kepler's Laws Of Planetary Motion
In astronomy, Kepler's laws of planetary motion, published by Johannes Kepler between 1609 and 1619, describe the orbits of planets around the Sun. The laws modified the heliocentric theory of Nicolaus Copernicus, replacing its circular orbits and epicycles with elliptical trajectories, and explaining how planetary velocities vary. The three laws state that: # The orbit of a planet is an ellipse with the Sun at one of the two foci. # A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. # The square of a planet's orbital period is proportional to the cube of the length of the semi-major axis of its orbit. The elliptical orbits of planets were indicated by calculations of the orbit of Mars. From this, Kepler inferred that other bodies in the Solar System, including those farther away from the Sun, also have elliptical orbits. The second law helps to establish that when a planet is closer to the Sun, it travels faster. The third law ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tychonic System
The Tychonic system (or Tychonian system) is a model of the Universe published by Tycho Brahe in the late 16th century, which combines what he saw as the mathematical benefits of the Copernican system with the philosophical and "physical" benefits of the Ptolemaic system. The model may have been inspired by Valentin Naboth and Paul Wittich, a Silesian mathematician and astronomer. A similar model was implicit in the calculations more than a century earlier by Nilakantha Somayaji of the Kerala school of astronomy and mathematics.Joseph, George G. (2000), ''The Crest of the Peacock: Non-European Roots of Mathematics'', p. 408, Princeton University Press, It is conceptually a geocentric model, or more precisely geoheliocentric: the Earth is at the centre of the universe, the Sun and Moon and the stars revolve around the Earth, and the other five planets revolve around the Sun. At the same time, the motions of the planets are mathematically equivalent to the motions in Copernic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
