Gemma Frisius
Gemma Frisius (; born Jemme Reinerszoon; December 9, 1508 – May 25, 1555) was a Dutch 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 teaching ...

Gaspard Van Der Heyden
Gaspard van der Heyden (also known as Gaspar à Myrica) (c. 1496 – c. 1549) was a goldsmith, Engraving, engraver, master Printer (publishing), printer and builder of precision astronomical instruments including Globe, 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 th ...

Baseline (surveying)
In surveying, a baseline is generally a line between two points on the Earth's surface and the direction and/or distance between them. In a triangulation network, at least one distance between two stations needs to be measured to calculate the size of the triangles by trigonometry. In relative Global Navigation Satellite System (GNSS) surveying, a baseline is the line between two GNSS receivers to determine the 3D coordinate difference. United States In the United States Public Land Survey System, a baseline is specifically 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 (north-south line) 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 ...

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 Snellius, 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 Position resection and intersection, 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 refere ...

Tycho Brahe
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. Tycho Brahe has also been described as the greatest pre-telescopic astronomer. In 1572, Tycho noticed a completely SN 1572, 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). Frederick II of Denmark, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Latinisation of names, Latinised name, adopted when he matriculated at the Old University of Louvain, 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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
