Virtually nothing is known about Ptolemys life except what can be inferred from his writings. The numerical tables in the Almagest (which enabled planetary positions and other celestial phenomena to be calculated for arbitrary dates) had a profound influence on medieval astronomy, in part through a separate, revised version of the tables that Ptolemy published as Procheiroi kanones (Handy Tables). Islam requires each Muslim to have at least enough knowledge of geography to know the direction of the Qiblah 4. Category:Geography (Ptolemy) English: Geography or Cosmographia is a name of an old atlas, written by Ptolemy (2nd century). Through the course of a year the Sun slowly traces out a great circle, known as the ecliptic, against the rotation of the celestial sphere. Ptolemys fame as a geographer is hardly less than his fame as an astronomer. He was a Greek-Roman citizen, who displayed multiple talents of astronomy, mathematics, georgraphy, astrology and poetry. At the end of the 1400s his work was rediscovered and translated into Latin, a more commonly used language of western scholars at the time. During the second century AD, Ptolemy (circa 100 - 178 AD) made some important contributions to geography. Unit 2702, NUO Centre PTOLEMY (OR CLAUDIUS PTOLEMAEUS) (b.c. Egyptian astronomer, mathematician, and geographer. Berggren, J. Lennart and Jones, Alexander. 3. Ptolemy begins with a theoretical introduction to the subjects of geography and of mapmaking and then proceeds to a long, long list of all the places that should be in the map, along with their latitudes and longitudes. One problem modern historians have encountered when researching Ptolemys work is that his works were all copied by hand and redistributed. His father was a physician and when he died his widow lacked any means . Ptolemys mathematical model of the universe had a profound influence on medieval astronomy in theIslamic worldandEurope. Franais : Gographie ou Cosmographie est le nom d'un vieux atlas, ecrit par Claude Ptolme (2e siecle).

This page was last edited on 7 September 2022, at 00:43. United States Another reason why Macbeth is a villain is because he continued to . But more importantly, he introduced the practice of writing down coordinates of latitude and longitude for every feature drawn on a world map, so that someone else possessing only the text of the Geography could reproduce Ptolemys map at any time, in whole or in part, at any scale. He believed that astrology is a legitimate, though inexact, science that describes the physical effects of the heavens on terrestrial life. In contrast, Ptolemy established this principle by measuring angles of incidence and reflection for planar and curved mirrors set upon a disk graduated in degrees. He introduced improvements to the construction of maps and developed a system of nautical charts. 4. He was the first one . He invented the concept of latitude and longitude, a mapping system still commonly used today. Galileo Galilei. Eratosthenes may have been the first to use the word geography.

Ptolemy championed the use of astronomical . In several fields his writings represent the culminating achievement of Greco-Roman science, particularly his geocentric (Earth-centred) model of the universe now known as the Ptolemaic system. Brahe pointed out that solar observations Ptolemy claimed to have made in 141 are definitely not genuine, and there are strong arguments for doubting that Ptolemy independently observed the more than 1,000 stars listed in his star catalog.

It supersedes all previous translations and corrects all editions. The text of Geographia reached Europe from Constantinople around AD 1400. Written in the second century AD, for more than fifteen centuries it was the most detailed topography of Europe and Asia available and the best reference on how to gather data and draw maps.

Ptolemy also measured how lines of sight are refracted at the boundary between materials of different density, such as air, water, and glass, although he failed to discover the exact law relating the angles of incidence and refraction (Snells law). 5. What is not disputed, however, is the mastery of mathematical analysis that Ptolemy exhibited. He also applied fundamental theorems in spherical trigonometry (apparently discovered half a century earlier by Menelaus of Alexandria) to the solution of many basic astronomical problems. He authored three books with historical significance: 1) the Almagest (in; Greek, The Great Treatise) on mathematics; 2) Geographia; and 3) Terabiblos (Four Books) about astrology and phillosphy.
