You'll probably remember that he says early in the essay that in order to recognize that we are in the presence of something that isn't merely within our own historical horizon, we need to be "pulled up short."
你们大概记得他在论文前面就讲过,为了意识到自己不仅仅在,一些我们时期出现的东西周围,我们需要“突然停下“
Well, it's true that it's not stuck to plastic but it is stuck to other materials The other materials that it's stuck to include other cells that surround it and this complex matrix which surrounds all of the cells in our body called extracellular matrix and I'll get to that in just a few moments.
体内的细胞不会贴在塑料片上,但是它们会和别的材料黏联在一起,这些材料包括,细胞和周围细胞间的黏联,细胞同细胞外基质的黏联,我们身体中包围在细胞周围的物质,称为细胞外基质,后面我会详细讲到
And it says something, in a way, about how easily we can be misled as to what things in our environment, even things coming from our own body, mean.
说是的,在某种意义上,我们很容易,被周围环境中的事物所误导,甚至被来自我们自身的东西误导。

And if we go ahead and square that, then what we get is a probability density, and specifically it's the probability of finding an electron in a certain small defined volume away from the nucleus.
我们得到的是,一个概率密度,它是,在核子周围,某个很小的,特定区域,找到电子的概率,所以它是概率密度。
So I said that we want to be talking about valence electrons here, so that means if we're talking about, for example, the octet rule for an f f molecule where we have two fluorine atoms, we need to write the valence electrons as dots around them.
我说过我们在这要讨论的是价电子,这就意味着,如果我们要讨论,比如,关于两个氟原子组成的分子的八隅体规则,我们首先需要把价电子画成围绕在它们周围的点。
So these organisms like this are abundant in the world around us and our immune system prevents us from getting sick most of the time.
