-【老师】当人类看向

0:00:01.240,0:00:02.540
我们身边的宇宙时

0:00:02.540,0:00:04.640
我们被其的复杂性吹走了

0:00:04.640,0:00:06.920
并且我们所看到的事物的种类

0:00:06.920,0:00:10.660
从宇宙中事物的规模来看，比如星星

0:00:10.660,0:00:12.080
这是太阳的一张图片

0:00:12.080,0:00:14.480
一直到更（趋于）人类的尺度

0:00:14.480,0:00:16.630
并且直到微观的尺度

0:00:16.630,0:00:19.360
这是冠状病毒的可视化（图）

0:00:19.360,0:00:22.090
这看上去似乎有无数个

0:00:22.090,0:00:23.570
东西在这

0:00:23.570,0:00:26.130
但一直有个有趣的问题

0:00:26.130,0:00:28.420
有没有一些基本的构建块

0:00:28.420,0:00:31.160
事物，更小规格的，有限事物的集合

0:00:31.160,0:00:35.210
我们可以将其组合在一起以构造这里所有的复杂事物呢

0:00:35.210,0:00:36.480
古人想，

0:00:36.480,0:00:38.710
也许是火，水，风

0:00:38.710,0:00:41.620
但我们现在知道这些食物称作元素

0:00:41.620,0:00:43.220
并且我们将其归类

0:00:43.220,0:00:45.340
在元素周期表上

0:00:45.340,0:00:48.750
距今我们已知118种元素

0:00:48.750,0:00:50.490
但我们可能会发现更多

0:00:50.490,0:00:52.870
但令人感到兴奋的是
