Erhard Etzlaub
Erhard Etzlaub ( 1455 1465 – 1532) was a German astronomer, geodesist, cartographer, instrument maker and physician. Life Little is known of Etzlaub's life. One "Erhart Etzlauber" became a citizen of Nuremberg in 1484, but his profession was not recorded on that occasion. Assuming that the "Eberhardus Eczleiben" who matriculated at the ''Erfurter Hochschule'' in 1468 is the same person, then the year of his birth should be between 1455 and 1460 rather than later. Letters from a third party dated 1500 and 1507 describe Etzlaub as a well-known instrument ("compass") maker and a geodesist, and a letter dated 1517 reveals that "he had also practicised as a physician for at least four years" and that he "comes from Erfurt". In 1515, he declared himself to be an "astronomer and physician, from Erfurt University". His death is officially quoted as the 15th entry in an official list of 20 people buried between December 20, 1531 and February 21, 1532. Therefore, he very probably died i ...

Austria
Austria, , bar, Östareich officially the Republic of Austria, is a country in the southern part of Central Europe, lying in the Eastern Alps. It is a federation of nine states, one of which is the capital, Vienna, the most populous city and state. A landlocked country, Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has a population of 9 million. Austria emerged from the remnants of the Eastern and Hungarian March at the end of the first millennium. Originally a margraviate of Bavaria, it developed into a duchy of the Holy Roman Empire in 1156 and was later made an archduchy in 1453. In the 16th century, Vienna began serving as the empire's administrative capital and Austria thus became the heartland of the Habsburg monarchy. After the dissolution of the H ...

Regensburg
Regensburg or is a city in eastern Bavaria, at the confluence of the Danube, Naab and Regen rivers. It is capital of the Upper Palatinate subregion of the state in the south of Germany. With more than 150,000 inhabitants, Regensburg is the fourth-largest city in the State of Bavaria after Munich, Nuremberg and Augsburg. From its foundation as an imperial Roman river fort, the city has been the political, economic and cultural centre of the surrounding region; it is still known in the Romance languages by a cognate of its Latin name of "Ratisbona" (the version "Ratisbon" was long current in English). Later, under the rule of the Holy Roman Empire, it housed the Perpetual Diet of Regensburg. The medieval centre of the city was made a UNESCO World Heritage Site in 2006 because of its well-preserved architecture and the city's historical importance for assemblies during the Holy Roman Empire. In 2014, Regensburg was among the top sights and travel attractions in Germany. Histor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mercator Projection
The Mercator projection () is a cylindrical map projection presented by Flemish geographer and cartographer Gerardus Mercator in 1569. It became the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes. The map is thereby conformal. As a side effect, the Mercator projection inflates the size of objects away from the equator. This inflation is very small near the equator but accelerates with increasing latitude to become infinite at the poles. As a result, landmasses such as Greenland, Antarctica and Russia appear far larger than they actually are relative to landmasses near the equator, such as Central Africa. History There is some controversy over the origins of the Mercator. German polymath Erhard Etzlaub engraved miniature "compass maps" (about 10×8 cm) of Europe and parts of Africa that spanned latitudes 0°–67° to allow adjustment of his portable pocket-s ...

Equator
The equator is a circle of latitude, about in circumference, that divides Earth into the Northern and Southern hemispheres. It is an imaginary line located at 0 degrees latitude, halfway between the North and South poles. The term can also be used for any other celestial body that is roughly spherical. In spatial (3D) geometry, as applied in astronomy, the equator of a rotating spheroid (such as a planet) is the parallel (circle of latitude) at which latitude is defined to be 0°. It is an imaginary line on the spheroid, equidistant from its poles, dividing it into northern and southern hemispheres. In other words, it is the intersection of the spheroid with the plane perpendicular to its axis of rotation and midway between its geographical poles. On and near the equator (on Earth), noontime sunlight appears almost directly overhead (no more than about 23° from the zenith) every day, year-round. Consequently, the equator has a rather stable daytime temperature throug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
67th Parallel North
The 67th parallel north is a circle of latitude that is 67 degrees north of the Earth's equatorial plane, about 50 km north of the Arctic Circle. It crosses the Atlantic Ocean, Europe, Asia and North America. At this latitude the sun is visible for 24 hours, 0 minutes during the summer solstice and 1 hour, 30 minutes during the winter solstice.

Johannes Cochlaeus
Johann Cochlaeus (Cochläus) (1479 – 10 January 1552) was a German humanist, music theorist, and controversialist. Life Originally Johann Dobneck, he was born of poor parents at Wendelstein (near Nuremberg), from which he obtained the punning surname Cochlaeus (spiral), for which he occasionally substituted Wendelstinus. Educated at Nuremberg by the humanist Heinrich Grieninger, he entered the University of Cologne in 1504, and there associated with Hermann von Neuenahr, Ulrich von Hutten, and other humanists. He also knew well Carl von Miltitz, who later became papal chamberlain.'' Schaff-Herzog Encyclopedia'', article on Cochlaeus by T. Kolde. In 1507 he graduated; he left Cologne in May 1510 to become schoolmaster at Nuremberg, where he brought out several school manuals. During the years 1515-19 he traveled in Italy as tutor to three nephews of Willibald Pirkheimer. In 1515 he was at Bologna, hearing (with disgust) Eck's disputation on the subject of usury, and ass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martin Behaim
Martin Behaim (6 October 1459 – 29 July 1507), also known as and by various forms of , was a German textile merchant and cartographer. He served John II of Portugal as an adviser in matters of navigation and participated in a voyage to West Africa. He is now best known for his Erdapfel, the world's oldest surviving globe, which he produced for the Imperial City of Nuremberg in 1492. Biography Behaim was born in Nuremberg on 6 October 1459, the oldest son of Martin Behaim and Agnes Schopper. The elder Martin was a merchant involved in long-distance trade within Europe, including Venice; in 1461 he was elected a senator of Nuremberg. Their son, as a member of a prominent and prosperous family, likely received a good education at one of the best grammar schools in the city. Contrary to later assertions, it is unlikely that he was ever a student of the famous Renaissance mathematician and astronomer, Regiomontanus.Görz, 2007Ravenstein, 1908 When his father died in 1474, Mar ...

Regiomontanus
Johannes Müller von Königsberg (6 June 1436 – 6 July 1476), better known as Regiomontanus (), was a mathematician, astrologer and astronomer of the German Renaissance, active in Vienna, Buda and Nuremberg. His contributions were instrumental in the development of Copernican heliocentrism in the decades following his death. Regiomontanus wrote under the Latinized name of ''Ioannes de Monteregio'' (or ''Monte Regio''; ''Regio Monte''); the toponym ''Regiomontanus'' was first used by Philipp Melanchthon in 1534. He is named after Königsberg, Bavaria, Königsberg in Lower Franconia, not the larger Königsberg (modern Kaliningrad) in Prussia. Life Although little is known of Regiomontanus' early life, it is believed that at eleven years of age, he became a student at the University of Leipzig, Electorate of Saxony, Saxony. In 1451 he continued his studies at University of Vienna, Alma Mater Rudolfina, the university in Vienna, Duchy of Austria, Austria. There he became a pupil ...

Sundials
A sundial is a horological device that tells the time of day (referred to as civil time in modern usage) when direct sunlight shines by the apparent position of the Sun in the sky. In the narrowest sense of the word, it consists of a flat plate (the ''dial'') and a gnomon, which casts a shadow onto the dial. As the Sun appears to move through the sky, the shadow aligns with different hour-lines, which are marked on the dial to indicate the time of day. The ''style'' is the time-telling edge of the gnomon, though a single point or ''nodus'' may be used. The gnomon casts a broad shadow; the shadow of the style shows the time. The gnomon may be a rod, wire, or elaborately decorated metal casting. The style must be parallel to the axis of the Earth's rotation for the sundial to be accurate throughout the year. The style's angle from horizontal is equal to the sundial's geographical latitude. The term ''sundial'' can refer to any device that uses the Sun's altitude or azimuth ( ...
