在数学史乃至整个科学史中,很少有一个分支能像非欧几何一样对人类认识史发生如此直接的影响.它的创立,不仅决定了近百年来数学许多领域的发展,而且对现代天文学、宇宙学、物理学的进步以及人类时空观念的变革都产生深远影响.正如伟大的物理学家爱因斯坦所指出的:“已经有大量? In the history of mathematics and even the entire history of science, there is very few branches that can have such direct impact on the history of human cognition as non-European geometry. Its establishment not only determines the development of many fields of mathematics in the past hundred years, but also the modern astronomy. Advances in cosmology, physics, and the transformation of human concepts of time and space have had far-reaching effects. As the great physicist Einstein pointed out: "There is already a lot?
