英文
euclid-
As we all known, with the founding of euclidean geometry in ancient greece, with the development of analytic geometry and other kinds of geometries, with f. kline " s erlanger program in 1872 and the new developments of geometry in 20th century such as topology and so on, man has developed their understand of geometry. on the other hand, euclid formed geometry as a deductive system by using axiomatic theory for the first time. the content and method of geometry have dramatically changed, but the geometry curriculum has not changed correspondingly until the first strike from kline and perry " s appealing
縱觀幾何學發展的歷史,可以稱得上波瀾壯闊:一方面,從古希臘時代的歐氏綜合幾何,到近代解析幾何等多種幾何的發展,以及用變換的方法處理幾何的埃爾朗根綱領,到20世紀拓撲學、高維空間理論等幾何學的新發展,這一切都在不斷豐富人們對幾何學的認識;另一方面,從歐幾里得第一次使用公理化方法把幾何學組織成一個邏輯演繹體系,到羅巴切夫斯基非歐幾何的發現,以及希爾伯特形式公理體系的建立,極大地發展了公理化思想方法,不管是幾何學的內容還是方法都發生了質的飛躍。That is how euclid did things in alexandria two millennia ago, and his treatise on geometry is the classical model for mathematical exposition
