00:00:07.158 --> 00:00:08.800
我们从一个点开始

00:00:08.800 --> 00:00:10.430
就是几何学里的“点”

00:00:10.430 --> 00:00:13.349
它没有边缘，没有维度

00:00:13.349 --> 00:00:15.238
只是一个想象的概念

00:00:15.238 --> 00:00:17.424
用于指代空间体系中的一个点

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

00:00:21.943 --> 00:00:24.346
它的大小同样是不定的

00:00:24.346 --> 00:00:25.835
为了创造一维世界

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

00:00:29.492 --> 00:00:32.104
我们的一维物体只有长度

00:00:32.104 --> 00:00:36.519
没有宽度或者深度

00:00:36.519 --> 00:00:38.844
如果我们像创造一维世界那样

00:00:38.844 --> 00:00:40.411
画出第二条线

00:00:40.411 --> 00:00:41.848
来穿过第一条

00:00:41.848 --> 00:00:43.807
我们就创造了二维世界

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

00:00:46.498 --> 00:00:47.856
但仍然没有深度

00:00:47.856 --> 00:00:50.155
为了帮助我们理解更高的维度

00:00:50.155 --> 00:00:52.349


00:00:52.349 --> 00:00:56.816


00:00:56.816 --> 00:01:02.511


00:01:02.511 --> 00:01:06.743


00:01:06.743 --> 00:01:08.598


00:01:08.598 --> 00:01:10.191


00:01:10.191 --> 00:01:14.266


00:01:14.266 --> 00:01:15.337


00:01:15.337 --> 00:01:17.949


00:01:17.949 --> 00:01:19.935


00:01:19.935 --> 00:01:23.096


00:01:23.096 --> 00:01:26.439


00:01:26.439 --> 00:01:28.163


00:01:28.163 --> 00:01:30.149


00:01:30.149 --> 00:01:31.690


00:01:31.690 --> 00:01:33.675


00:01:33.675 --> 00:01:35.817


00:01:35.817 --> 00:01:37.802


00:01:37.802 --> 00:01:39.448


00:01:39.448 --> 00:01:42.191


00:01:42.191 --> 00:01:43.863


00:01:43.863 --> 00:01:45.848


00:01:51.110 --> 00:01:54.338


00:01:54.338 --> 00:01:59.092


00:01:59.092 --> 00:02:02.018


00:02:02.018 --> 00:02:04.839


00:02:04.839 --> 00:02:07.478


00:02:07.478 --> 00:02:08.836


00:02:08.836 --> 00:02:11.161


00:02:11.161 --> 00:02:15.158


00:02:15.158 --> 00:02:18.344


00:02:18.344 --> 00:02:20.826


00:02:20.826 --> 00:02:23.830


00:02:23.830 --> 00:02:26.469


00:02:26.469 --> 00:02:29.917


00:02:29.917 --> 00:02:32.667


00:02:32.667 --> 00:02:34.567


00:02:34.567 --> 00:02:36.552


00:02:36.552 --> 00:02:39.216


00:02:39.216 --> 00:02:41.115
