Gemma Frisius
Gemma Frisius (; born Jemme Reinerszoon; December 9, 1508 – May 25, 1555) was a Frisian physician, mathematician, cartographer, philosopher, and instrument maker. He created important globes, improved the mathematical instruments of his day and applied mathematics in new ways to surveying and navigation. Gemma's rings, an astronomical instrument, are named after him. Along with Gerardus Mercator and Abraham Ortelius, Frisius is often considered one of the founders of the Netherlandish school of cartography, and significantly helped lay the foundations for the school's golden age (approximately 1570s–1670s). Biography Frisius was born in Dokkum, Friesland (present-day Netherlands), of poor parents who died when he was young. He moved to Groningen and later studied at the University of Leuven (Louvain), Belgium, beginning in 1525. He received the degree of MD in 1536 and remained on the faculty of medicine of Leuven for the rest of his life where, in addition to te ...

Gaspard Van Der Heyden
Gaspard van der Heyden (also known as Gaspar à Myrica) (c. 1496 – c. 1549) was a goldsmith, engraver, master printer and builder of precision astronomical instruments including terrestrial and celestial globes from Leuven, Belgium. He was well known among the humanists in Leuven as well as among scientists and mathematicians. Life Gaspard was the son of the surgeon Peter van der Heyden and Katharina van den Berghe. He was born around 1496 in Leuven. He's recorded to have married his wife, Anna van Luye in 1521. Little of his early life and education are recorded, but he was considered to be more than an artist, an engraver, a highly qualified craftsman, and a metal worker. He certainly had scientific education, especially in mathematics. A letter from Prof. Goglenius of Leuven dated December 2, 1531, to a friend of Erasmus, namely, to John Dantiscus, Polish policeman in the Netherlands, and great protector of Gemma Frisius, shows us that he and several other local humanists ...

The country is bordered by the Netherlands to the north, Germany to the east, Luxembourg to the southeast, France to the southwest, and the North Sea to the northwest. It covers an area of and has a population of more than 11.5 million, making it the 22nd most densely populated country in the world and the 6th most densely populated country in Europe, with a density of . Belgium is part of an area known as the Low Countries, historically a somewhat larger region than the Benelux group of states, as it also included parts of northern France. The capital and largest city is Brussels; other major cities are Antwerp, Ghent, Charleroi, Liège, Bruges, Namur, and Leuven.

Brussels
Brussels (french: Bruxelles or ; nl, Brussel ), officially the Brussels-Capital Region (All text and all but one graphic show the English name as Brussels-Capital Region.) (french: link=no, Région de Bruxelles-Capitale; nl, link=no, Brussels Hoofdstedelijk Gewest), is a region of Belgium comprising 19 municipalities, including the City of Brussels, which is the capital of Belgium. The Brussels-Capital Region is located in the central portion of the country and is a part of both the French Community of Belgium and the Flemish Community, but is separate from the Flemish Region (within which it forms an enclave) and the Walloon Region. Brussels is the most densely populated region in Belgium, and although it has the highest GDP per capita, it has the lowest available income per household. The Brussels Region covers , a relatively small area compared to the two other regions, and has a population of over 1.2 million. The five times larger metropolitan area of Brusse ...

Baseline (surveying)
In surveying, a baseline is a line between two points on the earth's surface and the direction and distance between them. In a triangulation network, at least one baseline between two stations needs to be measured to calculate the size of the triangles by trigonometry. In the United States Public Land Survey System, a baseline is the principal east-west line (i.e., a parallel) upon which all rectangular surveys in a defined area are based. The baseline meets its corresponding principal meridian at the point of origin, or '' initial point'', for the land survey. For example, the baseline for Nebraska and Kansas is shared as the border for both states, at the 40th parallel north. More specifically a baseline may be the line that divides a survey township between north and south. "Baseline Road" in the United States Many communities in the United States have roads that run along survey baselines, many of which are named to reflect that fact. Some examples: * In Little Rock, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triangulation (surveying)
In surveying, triangulation is the process of determining the location of a point by measuring only angles to it from known points at either end of a fixed baseline by using trigonometry, rather than measuring distances to the point directly as in trilateration. The point can then be fixed as the third point of a triangle with one known side and two known angles. Triangulation can also refer to the accurate surveying of systems of very large triangles, called triangulation networks. This followed from the work of Willebrord Snell in 1615–17, who showed how a point could be located from the angles subtended from ''three'' known points, but measured at the new unknown point rather than the previously fixed points, a problem called resectioning. Surveying error is minimized if a mesh of triangles at the largest appropriate scale is established first. Points inside the triangles can all then be accurately located with reference to it. Such triangulation methods were used for accur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tycho Brahe
Tycho Brahe ( ; born Tyge Ottesen Brahe; generally called Tycho (14 December 154624 October 1601) was a Danish astronomer, known for his comprehensive astronomical observations, generally considered to be the most accurate of his time. He was known during his lifetime as an astronomer, astrologer, and alchemist. He was the last major astronomer before the invention of the telescope. An heir to several noble families, Tycho was well-educated. He took an interest in astronomy and in the creation of more accurate instruments of measurement. He worked to combine what he saw as the geometrical benefits of Copernican heliocentrism with the philosophical benefits of the Ptolemaic system, and devised the Tychonic system, his own version of a model of the universe, with the Sun orbiting the Earth, and the planets as orbiting the Sun. In ''De nova stella'' (1573), he refuted the Aristotelian belief in an unchanging celestial realm. His measurements indicated that "new stars" (''stellae ...

Franciscus Monachus
Franciscus Monachus, (c. 1490 – 1565) was born Frans Smunck in Mechelen (or Malines) in the Duchy of Brabant (in modern-day Belgium). His Latinised name, adopted when he matriculated at the University of Louvain, is translated as simply ''Francis the monk''. ''Franciscus Monachus'' was identified as the Latinised form of his name, Frans Smunck, in his obituary notice. He is remembered as the cartographer who created the first terrestrial globe in the Low Countries. Biography Franciscus studied and taught at the university of Louvain from about 1510 to 1530 and numbered Gemma Frisius among his students. He was also an important influence on Gerardus Mercator. Very little is known of his life and the accounts which do exist are very brief. On leaving Louvain (Leuven) he returned the short distance to Mechelen where he spent the rest of his life in the monastery there. This was no backwater for the Great Council of Mechelen was the supreme court of the Low Countries and would be fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
