	Tycho Brahe (1546-1601)
		Tycho (whose original name was Tyge Brahe) was born in Skane (then Denmark, now Sweden) on December 14, 1546 and grew up as a nobleman in an uncle's castle.
		Tycho also invented a new (the "Tychonic") world system, opposing Copernicus because of the lack of observable stellar parallaxes: In his system, the planets Mercury, Venus, Mars, Jupiter and Saturn should orbit the Sun, but the Sun together with the Moon should revolve around an Earth at rest.
		Tycho left Denmark after the death of King Frederick in 1597, and in 1600, went to Prague to accept a post as Emperial Mathematician and Astronomer at the court of Rudolf II.

	Important Astronomers, their Instruments and Discoveries 1
		Tycho's observations of the nova of 1572, published in 1573, and lectures on astronomy he delivered in 1574 in Copenhagen, convinced the Danish king Fredrick II to grant Tycho an island on which to build an observatory, money to construct the needed instruments and a lifelong pension to run it.
		Tycho used equatorial armillary spheres for determining declinations and hour angles of objects anywhere in the sky.
		Tycho used an early form of vernier scales -- called transversals -- and compound sights on his instruments to measure objects to an accuracy of three arcminutes, better than his contemporaries by factors of 10 to 50.

	Development of Cometary Thought (Site not responding. Last check: 2007-10-03)
		Tycho Brahe (1546-1601), whose systematic and meticulous observational data enabled Johannes Kepler to formulate his planetary laws, wrote a German treatise on the comet of 1577, which he first noticed on November 13, 1577, and continued to observe for the next two and a half months.
		Tycho rejected the Aristotelian notion of comets by stating that the comet was certainly above the Moon's sphere.
		Tycho was the first to suggest that a comet's orbit may not be circular.

	Astronomy in Stamps
		Tycho Brahe (1546-1601) was the last and greatest of the naked-eye astronomers, rivalled only perhaps by Hipparchus.
		For over 20 years Tycho made observations from his castle Uraniborg on the island of Ven, given him as a fief by the king to keep the famed astronomer in Denmark.
		Johannes Kepler (1571-1630) was a German mathematician who is remembered for his three laws of planetary motion, derived empirically from Tycho Brahe's data and observations, which describe the solar system having the sun at the focus of elliptic planetary orbits.

	Giovanni Domenico Cassini and Christiaan Huygens
		In spite of his work in astronomy, he was very much inclined to the earth-centered theory of the Universe which was still the official view of the Church.
		Tycho Brahe made precise measurements of the planetary motions, the Sun, the Moon and the stars from 1576-1597, which became the foundation for Johannes Kepler's work.
		Tycho Brahe did not believe that the Sun was the center of the universe.

		Tycho's measurements are accurate to one arc-minute, equivalent to a 1 inch error at 100 yards, about what a good marksman can achieve with the naked eye.
		The problem was that Tycho's data were so accurate that deviations of any proposed mathematical model, his own or Copernicus's, could not be explained away as measurement error.
		Tycho's data were of such excellent quality that the conclusion stood on his data alone, aided of course by Galileo's discovery of another "planetary system" in the moons orbiting Jupiter.

	The Galileo Project
		He lived and studied with Erasmus Batholin, who was impressed enough with his work to entrust to him the editing of Tycho Brahe's manuscripts.
		1671, he accompanied Bartholin and Jean Picard to Hveen to observe the position of Tycho's observatory, then (1672) accompanied Picard back to Paris where he was assigned lodgings in the Royal Observatory and worked under the auspices of the Académie.
		1677, the Professorship of Astronomy in Copenhagen was designated for him.

		Chapelain was dead by 1677; the dedication was then a gift of gratitude for past favors.

	Cassini
		Observations would lead him to accept the model of the solar system proposed by Tycho Brahe and, in 1659, he presented an Earth centred system with the moon and sun orbiting the Earth and the other planets orbiting the sun.
		On their marriage Geneviève brought with her a dowry which included the Château de Thury in the Oise which became the Cassini summer residence for succeeding generations of the family.
		There were two sons from this marriage, the younger one Jacques Cassini being born in 1677 and eventually succeeding to his father's position as head of the Paris Observatory.

		In 1677 he became a member of the Royal Society.
		Near the end of the 16th century, Tycho Brahe of Denmark resolved to provide an observational basis for the renovation of astronomy.
		With his large and sturdy (but pre-telescopic) quadrants and sextants, he carefully measured the positions of 777 stars, to which he later added enough hastily observed stars to bring the catalog up to exactly 1,000.

	Background Reading: History
		Johannes Kepler, meanwhile, was shaking up the world by his meticulous use of astronomical data assembled by Tycho Brahe.
		What he discovered during these laborious hand calculations was that Venus would pass in front of the Sun on December 6th 1631, but the transit was not visible from Europe at all.
		Sir Edmund Halley (1656-1742), the namesake for Halley's Comet, made the same suggestion 14 years later in 1677 and published an important paper on the details of this technique in 1716.

	The First Known Variable Stars
		Soon after, some more variable stars were discovered, including the first periodic one, Mira (the periodicity of which was only discovered considerably later in 1638, by Holwarda; up to this time the four known variables had all been classified as "Stellae Novae", although none of them was actually a nova).

		A primary goal of these recorded observations was to confirm and extend the Rudolphine Tables, the project set up by Tycho Brahe and completed by Kepler, to facilitate calculation of the planet's positions (which goal in itself suggests Gassendi's adherence to a Keplerian heliocentrism).
		Another facet of Gassendi's empiricist astronomy was his denunciation of astrology as crafted independent of any ideas from the senses, impervious to correction by experiment or observation, and thus as failing to qualify as natural or experiential knowledge.
		The great triumph of Gassendi's scanning of the skies was his observation of Mercury's transit before the Sun (1631), the first such recorded observation and a confirmation of Kepler's prediction of the planetary orbits in accordance with the Three Laws.

		No account of this period of 150 years would be complete without mention of the Scientific Revolution (see Lecture 10).
		In the world of science, mathematics and astronomy, the age produced Nicolaus Copernicus, Giordano Bruno, Johannes Kepler, Tycho Brahe, Galileo, Robert Hooke, Robert Boyle, Edmund Halley, and Isaac Newton, in whose mind the wisdom of centuries of scientific thinking and endeavor seemed to find its ultimate expression.

		Turkey, as early as 1088 AH (AD 1677), took over the solar (Julian) year with its month names but kept the Muslim Era.

		In 1699-1700, Denmark and the Dutch and German Protestant states embraced the New Style, although the Germans declined to adopt the rules laid down for determining Easter, preferring to rely on astronomical tables and specifying the use of the Tabulae Rudolphinae (Rudolphine Tables), based on the 16th century observations of Tycho Brahe.

		Galileo Galilaei (1564-1642) compared apparent diameter of sun with estimated telescopic diameter of mag 6 star, assumed the same absolute size as the sun, concluded that the star was 2,160 AU distant.
		Galileo also advocated varying distances of stars and proposed use of differential parallax for bright stars (assuming that they were closer than faint stars).
