Physical geography

Physical geography (also known as geosystems or physiography) is one of the two major sub-fields of geography. Physical geography is that branch of natural science which deals with the study of processes and patterns in the natural environment like the atmosphere, hydrosphere, biosphere, and geosphere, as opposed to the cultural or built environment, the domain of human geography.

Within the body of physical geography, the Earth is often split into several spheres or environments, the main spheres being the atmosphere, biosphere, cryosphere, geosphere, hydrosphere, lithosphere and pedosphere. Research in physical geography is often interdisciplinary and uses the systems approach.

Sub-branches

Physical Geography can be divided into several sub-fields, as follows:

Geography

Geography (from Greek γεωγραφία, geographia, lit. "earth description") is a field of science devoted to the study of the lands, the features, the inhabitants, and the phenomena of Earth. A literal translation would be "to describe or picture or write about the earth". The first person to use the word "geography" was Eratosthenes (276–194 BC). Four historical traditions in geographical research are spatial analysis of the natural and the human phenomena (geography as the study of distribution), area studies (places and regions), study of the human-land relationship, and research in the Earth sciences. Nonetheless, modern geography is an all-encompassing discipline that foremost seeks to understand the Earth and all of its human and natural complexities—not merely where objects are, but how they have changed and come to be. Geography has been called "the world discipline" and "the bridge between the human and the physical science". Geography is divided into two main branches: human geography and physical geography.

Wing Chun

Wing Chun (Chinese: 詠春; pinyin: yǒng chūn; Jyutping: wing⁶ ceon¹; literally: "spring chant"), also romanised as Ving Tsun or Wing Tsun, (and sometimes substituted with the characters 永春 "eternal springtime"); is a concept-based Chinese martial art and form of self-defense utilising both striking and grappling while specialising in close-range combat.

The alternative characters 永春 "eternal spring" are also associated with some other southern Chinese martial arts, including Weng Chun Kung Fu and Yong Chun .

History

The earliest known mentions of Wing Chun date to the period of Red Boat Opera.

The common legend as told by Yip Man involves the young woman Yim Wing-chun during the period after the destruction by the Qing government of the Southern Shaolin and its associated temples.

Having rebuffed the local warlord's marriage offer, Yim Wing-Chun said she'd reconsider the proposal if he could beat her in a fight. She soon crossed paths with a Buddhist nun named Ng Mui, who was one of the Shaolin Sect survivors, and asked the nun to teach her to fight. According to legend Ng Mui taught Yim Wing-Chun a new system of martial art that had been inspired by the nun's observations of a confrontation between a Snake and a Crane. This then-still nameless style enabled Yim Wing-Chun to beat the warlord in a one-on-one fight. Yim Wing-Chun thereafter married Leung Bac-Chou and taught him the style, which was later named after her.
