E. G. Ravenstein
Ernst Georg Ravenstein (Ernest George) (30 December 1834 – 13 March 1913) was a German-English geographer and cartographer. As a geographer he was less of a traveller than a researcher; his studies led mainly in the direction of cartography and the history of geography. Ravenstein was born in Frankfurt am Main, Germany, to a family of cartographers. He spent most of his adult life in England in a house at Lorn Road, Lambeth, but he died in Germany, his country of birth, on 13 March 1913. Work on geography When he was 18 years old he became a pupil of Dr. August Heinrich Petermann. After moving to England, Ravenstein became a naturalised British Subject and was in the service of the Topographical Department of the British War Office for 20 years, from 1855 to 1875. A long-serving member of the councils of the Royal Statistical and Royal Geographical Societies, he was also Professor of Geography at Bedford College in 1882–83. He was the first to receive the Victoria go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Statistical Society
The Royal Statistical Society (RSS) is an established statistical society. It has three main roles: a British learned society for statistics, a professional body for statisticians and a charity which promotes statistics for the public good. History The society was founded in 1834 as the Statistical Society of London, though a perhaps unrelated London Statistical Society was in existence at least as early as 1824. At that time there were many provincial statistics societies throughout Britain, but most have not survived. The Manchester Statistical Society (which is older than the LSS) is a notable exception. The associations were formed with the object of gathering information about society. The idea of statistics referred more to political knowledge rather than a series of methods. The members called themselves " statists" and the original aim was "...procuring, arranging and publishing facts to illustrate the condition and prospects of society" and the idea of interpreti ...

Sporting Association
A sports club or sporting club, sometimes an athletics club or sports society or sports association, is a group of people formed for the purpose of playing sports. Sports clubs range from organisations whose members play together, unpaid, and may play other similar clubs on occasion, watched mostly by family and friends, to large commercial organisations with professional players which have teams that regularly compete against those of other clubs and sometimes attract very large crowds of paying spectators. Clubs may be dedicated to a single sport or to several (multi-sport clubs). The term "athletics club" is sometimes used for a general sports club, rather than one dedicated to athletics proper. Friedrich Ludwig Jahn's Turner movement, first realised at Volkspark Hasenheide in Berlin in 1811, was the origin of the modern sports clubs. Organization Larger sports clubs are characterized by having professional and amateur departments in various sports such as bike polo, ...

Step Migration
Step migration is a migration pattern conceptualized in 1885 by Ernst Georg Ravenstein, who observed migration as occurring stage by stage as rural inhabitants move closer to urban areas of growth. It is a migration pattern regarded by some scholars to be a widely popular form of international migration in the twenty-first century globalized world. There is a large breadth of study proving the existence of step migration in many international migration patterns, although there is lack of consensus over its exact specification and measurement. Step migration scholars deem it to be an important international trend that has the power to aid in the design of policy development efforts in both rural and urban areas worldwide. According to Abrahm Lustgarten, Senior Environmental Reporter for ProPublica, in his May 2021 report, Step migration – or "stepwise migration" – is a characteristic pattern of migration driven by climate change.

World Population Estimates
This article lists current estimates of the world population in history. In summary, estimates for the progression of world population since the Late Middle Ages are in the following ranges: Estimates for pre-modern times are necessarily fraught with great uncertainties, and few of the published estimates have confidence intervals; in the absence of a straightforward means to assess the error of such estimates, a rough idea of expert consensus can be gained by comparing the values given in independent publications. Population estimates cannot be considered accurate to more than two decimal digits; for example, the world population for the year 2012 was estimated at 7.02, 7.06, and 7.08 billion by the United States Census Bureau, the Population Reference Bureau, and the United Nations Department of Economic and Social Affairs, respectively, corresponding to a spread of estimates of the order of 0.8%. Deep prehistory As a general rule, the confidence of estimates on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carrying Capacity
The carrying capacity of an ecosystem is the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available. The carrying capacity is defined as the environment's maximal load, which in population ecology corresponds to the population equilibrium, when the number of deaths in a population equals the number of births (as well as immigration and emigration). Carrying capacity of the environment implies that the resources extraction is not above the rate of regeneration of the resources and the wastes generated are within the assimilating capacity of the environment. The effect of carrying capacity on population dynamics is modelled with a logistic function. Carrying capacity is applied to the maximum population an environment can support in ecology, agriculture and fisheries. The term carrying capacity had been applied to a few different processes in the past before finally being appl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Erdapfel
__NOTOC__ The ; ) is a terrestrial globe in diameter, produced by Martin Behaim from 1490 to 1492. The Erdapfel is the oldest surviving terrestrial globe. It is constructed of a laminated linen ball in two halves, reinforced with wood and overlaid with a map painted on Gore (segment), gores by Georg Glockendon. These intricate details were based on navigational charts by Jorge de Aguiar, incorporating paper maps meticulously pasted onto a parchment layer encircling the globe. The Americas are not included, as Voyages of Christopher Columbus, Columbus returned to Spain no sooner than March 1493. The globe shows an enlarged Eurasian continent and an empty ocean between Europe and Asia. The mythical Saint Brendan's Island is included.

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 known 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, Martin's ...

Vasco Da Gama
Vasco da Gama ( , ; – 24 December 1524), was a Portuguese explorer and nobleman who was the Portuguese discovery of the sea route to India, first European to reach India by sea. Da Gama's first voyage (1497–1499) was the first to link Europe and Asia using an Cape Route, ocean route that rounded the southern tip of Africa. This route allowed the Portuguese to avoid sailing across the highly disputed Mediterranean Sea and traversing the dangerous Arabian Peninsula, Arabian Peninsula. A milestone in Portuguese maritime exploration, this voyage marked the beginning of a sea-based phase of international trade and an age of global imperialism. The Portuguese later established a Portuguese Empire, long-lasting colonial empire along the route from Africa to Asia. The outward and return voyages constituted the longest known ocean voyages ever completed. Sailors had been trying to reach the Indies for decades, with thousands of lives and dozens of vessels lost in shipwrecks and ...
