Tycho Brahe (11853347315)
Tycho Brahe ( , ; born Tyge Ottesen Brahe, ; 14 December 154624 October 1601), generally called Tycho for short, was a Danish astronomer of the Renaissance, known for his comprehensive and unprecedentedly accurate astronomical observations. He was known during his lifetime as an astronomer, astrologer, and alchemist. He was the last major astronomer before the invention of the telescope. In 1572, Tycho noticed a completely new star that was brighter than any star or planet. Astonished by the existence of a star that ought not to have been there, he devoted himself to the creation of ever more accurate instruments of measurement over the next fifteen years (1576–1591). King Frederick II granted Tycho an estate on the island of Hven and the money to build Uraniborg, the first large observatory in Christian Europe. He later worked underground at Stjerneborg, where he realised that his instruments in Uraniborg were not sufficiently steady. His unprecedented research program bo ...

Knutstorp Castle
Knutstorp Castle ( sv, Knutstorps slott, da, Knutstrup borg) is a manor house situated in the Svalöv Municipality of Scania, Sweden. History A manor already in the middle of the 14th century, it was owned by the Danish Brahe noble family from the end of the Middle Ages until 1663, after Scania was ceded to Sweden in the treaty of Roskilde. The main building was completed in 1551 by the Danish Royal Privy Councilor Otte Brahe (1518–1571) and his wife Beate Clausdatter Bille (1526–1605). The estate was the birthplace of their children; the famous astronomer Tycho Brahe (1546–1601) and his astronomer sister Sophia Brahe (1556–1643). The estate was sold in 1771 to the Swedish Count Wachtmeister (Swedish family), Fredrik Georg Hans Carl Wachtmeister af Johannishus (1720–1792), and has since belonged to the members of his family.

Roman Mythology
Roman mythology is the body of myths of ancient Rome as represented in the literature and visual arts of the Romans. One of a wide variety of genres of Roman folklore, ''Roman mythology'' may also refer to the modern study of these representations, and to the subject matter as represented in the literature and art of other cultures in any period. Roman mythology draws from the mythology of the Italic peoples and ultimately from Proto-Indo-European mythology. Roman mythology also draws directly on Greek mythology, potentially as early as Rome's protohistory, but primarily during the Hellenistic period of Greek influence and through the Roman conquest of Greece, via the artistic imitation of Greek literary models by Roman authors. The Romans identified their own gods with those of the ancient Greeks—who were closely historically related in some cases, such as Zeus and Jupiter—and reinterpreted myths about Greek deities under the names of their Roman counterparts. Greek and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hven
Ven ( da, Hven, older Swedish spelling Hven) is a small Swedish island in the Øresund strait, between Scania and Zealand (Denmark). It is part of Landskrona Municipality, Scania County. The island has 371 inhabitants and an area of . During the 1930s, the population was at its peak, with approximately 1,300 inhabitants. There are four villages on the island: Bäckviken, Tuna By, Norreborg and Kyrkbacken. The island is best known as the location of Tycho Brahe's 16th-century observatories. Geography Unlike the relatively flat islands Amager and Saltholm, Ven rises from the Öresund with steep and dramatic coastlines. This makes the island easily visible from both Zealand and Scania, as well as from all ships that sail in and out of the Baltic Sea. Its southern coastline resembles the White Cliffs of Dover, Møns Klint and Cape Arkona, but owing to a higher degree of sand and lower of chalk, the cliffs are more yellow than white. Almost the entire island consists of a flat agric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frederick II Of Denmark
Frederick II (1 July 1534 – 4 April 1588) was King of Denmark and Norway and Duke of Schleswig and Holstein from 1559 until his death. A member of the House of Oldenburg, Frederick began his personal rule of Denmark-Norway at the age of 24. He inherited a capable and strong kingdom, formed in large by his father after the civil war known as the Count's Feud, after which Denmark saw a period of economic recovery and of a great increase in the centralised authority of the Crown. Frederick was, especially in his youth and unlike his father, belligerent and adversarial, aroused by honor and national pride, and so he began his reign auspiciously with a campaign under the aged Johan Rantzau, which reconquered Dithmarschen. However, after miscalculating the cost of the Northern Seven Years' War, he pursued a more prudent foreign policy. The remainder of Frederick II's reign was a period of tranquillity, in which king and nobles prospered. Frederick spent more time hunting and f ...

Celestial Spheres
The celestial spheres, or celestial orbs, were the fundamental entities of the cosmology, cosmological models developed by Plato, Eudoxus of Cnidus, Eudoxus, Aristotle, Ptolemy, Copernicus, and others. In these celestial models, the diurnal motion, apparent motions of the fixed stars and classical planet, planets are accounted for by treating them as embedded in rotating spheres made of an aetherial, transparent fifth element (aether (classical element), quintessence), like jewels set in orbs. Since it was believed that the fixed stars did not change their positions relative to one another, it was argued that they must be on the surface of a single starry sphere. In modern thought, the Orbit#Planetary orbits, orbits of the planets are viewed as the paths of those planets through mostly empty space. Ancient and medieval thinkers, however, considered the celestial orbs to be thick spheres of rarefied matter nested one within the other, each one in complete contact with the spher ...

SN 1572
SN 1572 ('' Tycho's Supernova'', ''Tycho's Nova''), or B Cassiopeiae (B Cas), was a supernova of Type Ia in the constellation Cassiopeia, one of eight supernovae visible to the naked eye in historical records. It appeared in early November 1572 and was independently discovered by many individuals. Its supernova remnant has been observed optically but was first detected at radio wavelengths; it is often known as 3C 10, a radio-source designation, although increasingly as Tycho's supernova remnant. Historic description The appearance of the Milky Way supernova of 1572 belongs among the most important observation events in the history of astronomy. The appearance of the "new star" helped to revise ancient models of the heavens and to speed on a revolution in astronomy that began with the realisation of the need to produce better astrometric star catalogues (and thus the need for more precise astronomical observing instruments). It also challenged the Aristotelian dogma of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invention Of The Telescope
The history of the telescope can be traced to before the invention of the earliest known telescope, which appeared in 1608 in the Netherlands, when a patent was submitted by Hans Lippershey, an eyeglass maker. Although Lippershey did not receive his patent, news of the invention soon spread across Europe. The design of these early refracting telescopes consisted of a convex objective lens and a concave eyepiece. Galileo improved on this design the following year and applied it to astronomy. In 1611, Johannes Kepler described how a far more useful telescope could be made with a convex objective lens and a convex eyepiece lens. By 1655, astronomers such as Christiaan Huygens were building powerful but unwieldy Keplerian telescopes with compound eyepieces. Isaac Newton is credited with building the first reflector in 1668 with a design that incorporated a small flat diagonal mirror to reflect the light to an eyepiece mounted on the side of the telescope.

Alchemist
Alchemy (from Arabic: ''al-kīmiyā''; from Ancient Greek: χυμεία, ''khumeía'') is an ancient branch of natural philosophy, a philosophical and protoscience, protoscientific tradition that was historically practiced in Chinese alchemy, China, Rasayana, India, the Alchemy and chemistry in medieval Islam, Muslim world, and Europe. In its Western form, alchemy is first attested in a number of pseudepigraphical texts written in Egypt (Roman province), Greco-Roman Egypt during the first few centuries AD.Principe, Lawrence M. The secrets of alchemy'. University of Chicago Press, 2012, pp. 9–14. Alchemists attempted to purify, mature, and perfect certain materials. Common aims were chrysopoeia, the transmutation of "base metals" (e.g., lead) into "noble metals" (particularly gold); the creation of an Elixir of life, elixir of immortality; and the creation of Panacea (medicine), panaceas able to cure any disease. The perfection of the human body and soul was thought to result f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astrologer
Astrology is a range of divinatory practices, recognized as pseudoscientific since the 18th century, that claim to discern information about human affairs and terrestrial events by studying the apparent positions of celestial objects. Different cultures have employed forms of astrology since at least the 2nd millennium BCE, these practices having originated in calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications. Most, if not all, cultures have attached importance to what they observed in the sky, and some—such as the Hindus, Chinese, and the Maya—developed elaborate systems for predicting terrestrial events from celestial observations. Western astrology, one of the oldest astrological systems still in use, can trace its roots to 19th–17th century BCE Mesopotamia, from where it spread to Ancient Greece, Rome, the Islamic world, and eventually Central and Western Europe. Contemporary Western astrology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomical Observation
Observational astronomy is a division of astronomy that is concerned with recording data about the observable universe, in contrast with theoretical astronomy, which is mainly concerned with calculating the measurable implications of physical models. It is the practice and study of observing celestial objects with the use of telescopes and other astronomical instruments. As a science, the study of astronomy is somewhat hindered in that direct experiments with the properties of the distant universe are not possible. However, this is partly compensated by the fact that astronomers have a vast number of visible examples of stellar phenomena that can be examined. This allows for observational data to be plotted on graphs, and general trends recorded. Nearby examples of specific phenomena, such as variable stars, can then be used to infer the behavior of more distant representatives. Those distant yardsticks can then be employed to measure other phenomena in that neighborhood, includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Renaissance
The Renaissance ( , ) , from , with the same meanings. is a period in European history marking the transition from the Middle Ages to modernity and covering the 15th and 16th centuries, characterized by an effort to revive and surpass ideas and achievements of classical antiquity. It occurred after the Crisis of the Late Middle Ages and was associated with great social change. In addition to the standard periodization, proponents of a "long Renaissance" may put its beginning in the 14th century and its end in the 17th century. The traditional view focuses more on the early modern aspects of the Renaissance and argues that it was a break from the past, but many historians today focus more on its medieval aspects and argue that it was an extension of the Middle Ages. However, the beginnings of the period – the early Renaissance of the 15th century and the Italian Proto-Renaissance from around 1250 or 1300 – overlap considerably with the Late Middle Ages, conventionally da ...

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...
