The concept of a space is an extremely general and important mathematical construct. Members of the space obey certain addition properties. Spaces which have been investigated and found to be of interest are usually named after one or more of their investigators. This practice unfortunately leads to names which give very little insight into the relevant properties of a given space.
空间是一个非常普通和重要的数学概念。各种空间有各种不同的属性。已被研究的空间,通常以一个或多个研究它们的研究人员命名。这种做法不幸地导致从名字很难看出与一个给定的空间有关的属性。
The everyday type of space familiar to most people is called Euclidean space. In Einstein';s theory of Special Relativity, Euclidean three-space plus time (the "fourth dimension") are unified into the so-called Minkowski space. One of the most general type of mathematical spaces is the topological space.
大多数人熟悉的常见类型的空间,称为欧几里得空间。在爱因斯坦狭义相对论中,欧几里得空间加上时间(“第四维”)统一成所谓的闵可夫斯基空间。在数学空间中,最常见的类型之一,是拓扑空间。
