Geography

World Geography Map Geography is the scientific study of the earth's surface and the World Geography Map depicts both the earth's physical features and the human phenomena on its surface that is the result of man's interaction with his physical environment. The World Geography map therefore not only shows the distribution of the earth's natural landforms on the surface of the globe but also depicts the elements of human intervention such as political boundaries and the division of the world into countries and independent states together with their capitals and principle cities. As far as the earth's physical features are concerned, the World Geography Map shows the distribution of the varied natural landforms and topographical features of the earth's surface on a global scale. The World Geography Map therefore depicts the main features of elevation and depression on the earth's surface and is also the most graphic representation of the earth's various contours and its most prominent physical features.

Ptolemy 2nd-century Roman mathematician, astronomer, geographer Unlike most ancient Greek mathematicians, Ptolemy's writings (foremost the Almagest) never ceased to be copied or commented upon, both in Late Antiquity and in the Middle Ages.[4] However, it is likely that only a few truly mastered the mathematics necessary to understand his works, as evidenced particularly by the many abridged and watered-down introductions to Ptolemy's astronomy that were popular among the Arabs and Byzantines alike.[5][6] Biography[edit] The 14th-century astronomer Theodore Meliteniotes gave his birthplace as the prominent Greek city Ptolemais Hermiou (Πτολεμαΐς Ἑρμείου) in the Thebaid (Θηβᾱΐς). Claudius Ptolemy died in Alexandria around 168.[11] Naming and nationality[edit] Engraving of a crowned Ptolemy being guided by Urania, from Margarita Philosophica by Gregor Reisch (1508), showing an early confluence between his person and the rulers of Ptolemaic Egypt.

Module Seven (B), Activity Two | Exploring Africa Colonial Exploration and Conquest in Africa This activity discusses colonialism in Africa. Colonialism has also been addressed in Module Six: Africa and Its Geography, Module Nine: Economics of Africa, Module Ten: African Politics and Government, and Module Fifteen: Africa and the World. What does colonialism mean? Take a couple of minutes to write a few sentences describing what you know already about colonialism in your Activity Journal. Also write down a few questions addressing what you do not understand or would like to learn about colonialism. Student Journal Assignment: What does colonialism mean? Colonialism is generally defined as the occupation and control of one nation by another. Look at the map below that lists colonial languages that are spoken in the various nations of Africa. Colonial Conquest in Africa The 19th century in Europe was a time of industrialization. Politics in Europe also led to the colonization of Africa.

Planisphaerium The mathematician Claudius Ptolemy 'the Alexandrian' as imagined by a 16th-century artist Publication[edit] Herman of Carinthia, translator of Planisphaerium, with an astrolabe Originally written in Ancient Greek, Planisphaerium was one of many scientific works which survived from antiquity in Arabic translation. One reason why Planisphaerium attracted interest was that stereographic projection was the mathematical basis of the plane astrolabe, an instrument which was widely used in the medieval Islamic world. In the 12th century the work was translated from Arabic into Latin by Herman of Carinthia, who also translated commentaries by Maslamah Ibn Ahmad al-Majriti. Planisphere[edit] The word planisphere (Latin planisphaerium) was originally used in the second century by Ptolemy to describe the representation of a spherical Earth by a map drawn in the plane.

Portal:Forestry From Wikipedia, the free encyclopedia A pine forest in Sweden Forestry is the science, art, and craft of creating, managing, using, conserving, and restoring forests and associated resources to meet desired goals, needs, and values for human benefit. Forestry is practiced in plantations and natural stands. The main goal of forestry is to create and implement systems that manage forests to provide environmental supplies and services. The challenge of forestry is to create systems that are socially accepted while sustaining the resource and any other resources that might be affected. Additional categories Purge server cache

Almagest Geometric construction used by Hipparchus in his determination of the distances to the sun and moon The Almagest (/ˈælməˌdʒɛst/) is a 2nd-century Greek-language mathematical and astronomical treatise on the apparent motions of the stars and planetary paths, written by Claudius Ptolemy (c. AD 100 – c. 170). One of the most influential scientific texts of all time, its geocentric model was accepted for more than 1200 years from its origin in Hellenistic Alexandria, in the medieval Byzantine and Islamic worlds, and in Western Europe through the Middle Ages and early Renaissance until Copernicus. The Almagest is the critical source of information on ancient Greek astronomy. It has also been valuable to students of mathematics because it documents the ancient Greek mathematician Hipparchus's work, which has been lost. An edition in Latin of the Almagestum in 1515 Ptolemy set up a public inscription at Canopus, Egypt, in 147 or 148. Names[edit] Contents[edit] Books[edit] Ptolemy's cosmos[edit]
