1
00:00:07,158 --> 00:00:08,800
我们从一个点开始

2
00:00:08,800 --> 00:00:10,430
就是几何学里的“点”

3
00:00:10,430 --> 00:00:13,349
它没有边缘，没有维度

4
00:00:13,349 --> 00:00:15,238
只是一个想象的概念

5
00:00:15,238 --> 00:00:17,424
用于指代空间体系中的一个点

6
00:00:17,424 --> 00:00:21,943
另一个点也可以用来指代另一个不同的位置

7
00:00:21,943 --> 00:00:24,346
它的大小同样是不定的

8
00:00:24,346 --> 00:00:25,835
为了创造一维世界

9
00:00:25,835 --> 00:00:29,492
我们需要做的只是把任意两个点连起来

10
00:00:29,492 --> 00:00:32,104
我们的一维物体只有长度

11
00:00:32,104 --> 00:00:36,519
没有宽度或者深度

12
00:00:36,519 --> 00:00:38,844
如果我们像创造一维世界那样

13
00:00:38,844 --> 00:00:40,411
画出第二条线

14
00:00:40,411 --> 00:00:41,848
来穿过第一条

15
00:00:41,848 --> 00:00:43,807
我们就创造了二维世界

16
00:00:43,807 --> 00:00:46,498
现在我们展示的物体已经有了长度和宽度

17
00:00:46,498 --> 00:00:47,856
但仍然没有深度

18
00:00:47,856 --> 00:00:50,155
为了帮助我们理解更高的维度

19
00:00:50,155 --> 00:00:52,349


20
00:00:52,349 --> 00:00:56,816


21
00:00:56,816 --> 00:01:02,511


22
00:01:02,511 --> 00:01:06,743


23
00:01:06,743 --> 00:01:08,598


24
00:01:08,598 --> 00:01:10,191


25
00:01:10,191 --> 00:01:14,266


26
00:01:14,266 --> 00:01:15,337


27
00:01:15,337 --> 00:01:17,949


28
00:01:17,949 --> 00:01:19,935


29
00:01:19,935 --> 00:01:23,096


30
00:01:23,096 --> 00:01:26,439


31
00:01:26,439 --> 00:01:28,163


32
00:01:28,163 --> 00:01:30,149


33
00:01:30,149 --> 00:01:31,690


34
00:01:31,690 --> 00:01:33,675


35
00:01:33,675 --> 00:01:35,817


36
00:01:35,817 --> 00:01:37,802


37
00:01:37,802 --> 00:01:39,448


38
00:01:39,448 --> 00:01:42,191


39
00:01:42,191 --> 00:01:43,863


40
00:01:43,863 --> 00:01:45,848


41
00:01:51,110 --> 00:01:54,338


42
00:01:54,338 --> 00:01:59,092


43
00:01:59,092 --> 00:02:02,018


44
00:02:02,018 --> 00:02:04,839


45
00:02:04,839 --> 00:02:07,478


46
00:02:07,478 --> 00:02:08,836


47
00:02:08,836 --> 00:02:11,161


48
00:02:11,161 --> 00:02:15,158


49
00:02:15,158 --> 00:02:18,344


50
00:02:18,344 --> 00:02:20,826


51
00:02:20,826 --> 00:02:23,830


52
00:02:23,830 --> 00:02:26,469


53
00:02:26,469 --> 00:02:29,917


54
00:02:29,917 --> 00:02:32,667


55
00:02:32,667 --> 00:02:34,567


56
00:02:34,567 --> 00:02:36,552


57
00:02:36,552 --> 00:02:39,216


58
00:02:39,216 --> 00:02:41,115
