On February 4, 1600, Kepler met Tycho Brahe and his assistants Franz Tengnagel and Longomontanus at Benátky nad Jizerou ( 35 km from Prague ), the site where Tycho's new observatory was being constructed.

It was based upon the work of Tycho Brahe and may have borrowed from Alessandro Piccolomini's 1540 star atlas, De le stelle fisse, although Bayer included an additional 1, 000 stars.

He had since 1613 tried to get his mother's permission to marry the noblewoman Ebba Brahe, but this was not allowed, and he had to give up his wishes to marry her, though he continued to be in love with her.

The Islamic astronomer al-Sufi updated it in 964, and the star positions were redetermined by Ulugh Beg in 1437, but it was not fully superseded until the appearance of the thousand-star catalogue of Tycho Brahe in 1598.

Kepler was an astronomer who, using the accurate observations of Tycho Brahe, proposed that the planets move around the sun not in circular orbits, but in elliptical ones.

Tycho Brahe ( 14 December 154624 October 1601 ), born Tyge Ottesen Brahe, was a Danish nobleman known for his accurate and comprehensive astronomical and planetary observations.

Tycho Brahe was granted an estate on the island of Hven and the funding to build the Uraniborg, an early research institute, where he built large astronomical instruments and took many careful measurements, and later Stjerneborg, underground, when he discovered that his instruments in the former were not sufficiently steady.

Tycho was born at his family's ancestral seat of Knutstorp Castle ( Danish: Knudstrup borg ; Swedish: Knutstorps borg ), about eight kilometres north of Svalöv in then Danish Scania, now Swedish, to Otte Brahe ( of the Brahe family ) and Beate Bille ( of the Bille family ).

Otte Brahe, Tycho's father, was a nobleman and an important figure at the court of the Danish king.

Tycho later wrote that when he was around age two, his uncle, Danish nobleman Jørgen Thygesen Brahe, " without the knowledge of my parents took me away with him while I was in my earliest youth to become a scholar ".

Copernicus proposed the heliocentric universe, which was met with strong resistance, and Tycho Brahe refuted the theory of celestial spheres through observational measurement of the 1572 appearance of a Milky Way Super Nova.

It was more accurate than later measurements by Copernicus and Tycho Brahe.

This idea was disproved in 1577 by Tycho Brahe, who used parallax measurements to show that comets must lie beyond the Moon.

During what was called the Stockholm Bloodbath, close to 100 people were executed on Stortorget, among them Gustav Eriksson's father, Erik Johansson, and nephew, Joakim Brahe.

An example of such an event is the supernova SN 1572, which was observed by Tycho Brahe.

) The implicit false solar parallax of slightly under 3 ° was used by astronomers up to and including Tycho Brahe, ca.

He was supported and directed by Frederick III of Denmark to prepare for publication the collected manuscript observations of Tycho Brahe.

Johannes Kepler ( 27 December 1571 – 15 November 1630 ) was the first to closely integrate the predictive geometrical astronomy, which had been dominant from Ptolemy to Copernicus, with physical concepts to produce a New Astronomy, Based upon Causes, or Celestial Physics .... His work led to the modern laws of planetary orbits, which he developed using his physical principles and the planetary observations made by Tycho Brahe.

An attempted remedy was made by chancellor Nils Brahe, who traveled to Copenhagen, in the spring of 1675, to try to get the Danish princess Ulrika Eleonora engaged to the Swedish king.

During the 16th and 17th centuries, most of the land in eastern Täby was owned by the Brahe family of Rydboholm Castle.

The famous astronomer Tycho Brahe was born there.

However, the last city in Finland that was ordered to be built on a previously completely uninhabited land was Raahe, founded by governor general Per Brahe the Younger in 1649.

After further studies in Uppsala University, Königsberg University ( Królewiec University ) and some other universities, mainly in Germany, he was appointed teacher for the nephew of the Lord High Chancellor Peter Brahe.

Burke, Wills, King, Gray, Brahe, Mahomet, Patton and McDonough made their first camp on what they thought was Cooper Creek, but which was actually the Wilson River.

At the court of King Rudolf II, in Hradcany Castle, in Prague, Veranzio was chancellor for Hungary and Transylvania often in contact with Johannes Kepler and Tycho Brahe.

*** Ebba Brahe ( 1596 – 1674 ): lady-in-waiting and mistress of future King Gustavus Adolphus, wife of Jakob De la Gardie

When King Carl IX died and was succeeded by his son Gustavus Adolphus in 1611, Magnus Brahe remained a close confidant of the king, albeit a new one.

He was the grandson of Per Brahe ( the elder ) ( 1520 – 1590 ), one of Gustavus Vasa's Privy Councillors, created count of Visingsborg by Eric XIV of Sweden, known also as the continuator of Peder Svart's chronicle of Gustavus, and author of Oeconomia in 1585, a manual for young noblemen.

Per Brahe the younger, after completing his education by several years ’ travel abroad, became in 1626 chamberlain to Gustavus Adolphus, whose lasting friendship he gained.

Brahe took part in the long duel between Gustavus and Wallenstein around Nuremberg as general of infantry, and commanded the left wing at Lützen on November 6, 1632, where he was the only Swedish general officer present.

in 1618, De la Gardie married Ebba Brahe, the love of young Gustavus Adolphus.

This rendered futile any attempt to forcibly separate the couple, as had been done when the duke's elder brother was compelled to abandon his great love, Ebba Brahe, whose noble birth had likewise been deemed insufficient to allow Gustavus Adolphus to marry her.

Ebba Magnusdotter Brahe ( 16 March 1596 – 5 January 1674 ) was a lady-in-waiting in the Swedish court, countess, and the mistress of king Gustavus Adolphus of Sweden.

Brahe was knighted at the coronation of Gustavus Adolphus in October 1617.

He died in Stockholm on March 3, 1633, due to an illness, which possibly was caused by the great grief Brahe felt when king Gustavus Adolphus died.

The songs interspersed in the four operas which they produced together, viz., Gustaf Vasa, Gustaf Adolf och Ebba Brahe, Aeneas i Carthago, and Drottning Kristina, are wholly the work of Kellgren.

He also sought the opinions of many of the astronomers to whom he had sent Mysterium, among them Reimarus Ursus ( Nicolaus Reimers Bär )— the imperial mathematician to Rudolph II and a bitter rival of Tycho Brahe.

He became noted for the quality and accuracy of his instruments, which were praised by Tycho Brahe, among others.

In 1607 Count Abraham Brahe was appointed chancellor, but does not seem to have given much attention to the university, in contrast to the king's former tutor, the learned Johan Skytte, still remembered ( among other things ) for his donation of the Skyttean professorship, who was appointed chancellor in 1622 and can be said to begin the continuous chronological list of chancellors.

Johannes Kepler published his first two laws in 1609, having found them by analyzing the astronomical observations of Tycho Brahe.

Tycho Brahe developed the Rudolfine tables ( finished by Kepler, after Brahe's death ), the first comprehensive table of data of the movements of the planets.

The first accurate, modern, western observations of the obliquity were probably those of Tycho Brahe, about 1584, although observations by several others, including Purbach, Regiomontanus, and Walther, could have provided similar information.

The first two comprise entirely his Syntagma philosophicum ; the third contains his critical writings on Epicurus, Aristotle, Descartes, Robert Fludd and Herbert of Cherbury, with some occasional pieces on certain problems of physics ; the fourth, his Institutio astronomica, and his Commentarii de rebus celestibus ; the fifth, his commentary on the tenth book of Diogenes Laërtius, the biographies of Epicurus, Nicolas-Claude Fabri de Peiresc, Tycho Brahe, Nicolaus Copernicus, Georg von Peuerbach, and Regiomontanus, with some tracts on the value of ancient money, on the Roman calendar, and on the theory of music, with an appended large and prolix piece entitled Notitia ecclesiae Diniensis ; the sixth volume contains his correspondence.

Copernicus is mentioned for the first time in Hebrew in the books of David Gans ( 1541 – 1613 ), who worked with Tycho Brahe and Johannes Kepler.

Thereafter, the books were stored temporarily in various noble palaces in Stockholm, first in Count Lillie ’ s house on what was then Norrmalm Square ( 1697 – 1702 ), and later in the Bonde Palace ( 1702 – 1730 ), and Count Per Brahe ’ s house on Helgeandsholmen ( 1730 – 1768 ).

The regiment was also called Joakim Brahes regemente after its first commander Joakim Brahe.

The regiment's first commander was Nils Brahe.

Per Brahe was in 1561 granted dignity as a count by Eric XIV of Sweden and in 1620 was the family introduced on the Swedish House of Knights ( Riddarhuset ) as the first counts.

After Tycho Brahe had fallen out of favour and left Denmark, Christian Longomontanus had become Christian IV's new astronomer and the first professor of astronomy at the University of Copenhagen.

The first two of these are believed to have been derived by Bürgi, who related them to Brahe ; the others follow easily from these two.

Osiander's Italian pal, Dr. Cardano, who cures the asthmatic Archbishop John Hamilton, executed for helping Mary, Queen of Scots, whose lover, the explosive bearing Earl of Bothwell, ends up in Scandinavia with a friend of astronomer Tycho Brahe, whose assistant, Willem Blaeu, makes maps updated in the first true atlas by the Englishman Dudley, working in Italy for Bernardo Buontalenti, who got opera started, which was a rave success, especially with the French Cardinal Mazarin, whose library inspired the secretary of the English navy, which eventually buys French semaphore, after which Gamble gets the patent for canned food that feeds explorers like Hooker, who transplanted rubber trees to Sri Lanka.

* The Variation, discovered by Tycho Brahe, is a speeding-up of the Moon as it approaches new-moon and full-moon, and a slowing-down as it approaches first and last quarter.

A brilliant supernova ( SN 1572-thought, at the time, to be a comet ) is observed by Tycho Brahe, who proves that it is traveling beyond Earth's atmosphere and therefore provides the first evidence that the heavens can change.
