Taoism 101: Introduction to the Tao and What is Taoism

IntroductionQuotesOriginsSummaryExamplesDefinitionsReligionTo many people, a confusing aspect of Taoism is its very definition. Many religions will happily teach philosophy and dogma which in reflection defines a person. Taoism flips this around. It starts by teaching a truth; The Tao is indefinable. It then follows up by teaching that each person can discover the Tao on their terms. A teaching like this can be very hard to grasp when most people desire very concrete definitions in their own life. A simple way to start learning the definition of Taoism is to start within yourself. Here are three easy starting steps to learning Taoism:Get price

Geographic information system - Wikipedia

History and DevelopmentTechniques and TechnologySpatial Analysis with GISApplicationsSemanticsImplications of GIS on SocietyFurther ReadingThe phrase, "geographic information system", was coined by Roger Tomlinson in 1968, when he published the scientific paper, "A Geographic Information System for Regional Planning". Tomlinson, acknowledged as the "father of GIS", is credited with enabling the first computerized–GIS to be created through his work on the Canada Geographic Information Systemin 1963. Ultimately, Tomlinson created a framework for a database that was capable of storing and analyzing huge amounts of data; leading to the Canadian government being able to implement its National Land-Use Management Program. One of the first known instances in which spatial analysis was used, came from the field of epidemiology in the, "Rapport sur la marche et les effets du choléra dans Paris et le département de la Seine" (1832). French geographer and cartographer, Charles Picquet, created a map outlining the forty-eight Districts in Paris, using halftone color gradients, to provide a visual representation for the number of r...Get price
