geometry
Geometrical geometry. Geometry is a basic branch of mathematics, mainly to study the shape, size, graphics, relative position and other spatial regional relations and spatial form of measurement. Many cultures have geometrical developments, including many knowledge of length, area and volume, and in the era of Thales in the sixth century, the Western world began to regard geometry as part of mathematics. In the third century BC, the geometry of Euclid was added to the geometry, and the Euclidean geometry produced was the geometric standard for centuries. Archimedes developed the method of calculating the area and volume, many of which used the concept of integration. The relative position of stars and planets in the celestial sphere in astronomy, and their relative movements, is the subject of discussion in the follow-up period of one hundred and five hundred years. Geometry and astronomy are listed in the Western liberal arts education in the four surgery, is the medieval Western University, one of the contents of Professor. ...
