However, as you know, we didn't stop at the plum pudding model, which is good, because it's a little goofy, so it's nice to move on from that and move on we did.
我们并没有,停留在李子布丁模型上，虽然它很好,但这个模型有点傻。

Now, I'd like to stress information technology because we are living in a time of rapid advance, as you know--I don't have to tell you this.
我想强调一下信息技术,因为我们身处一个飞速发展的时代，这你们都知道，我没必要再说一遍。

We know that because they also have a writing which we can read, and it speaks of it as well as the archeological remains that show destruction.
他们有文字,所以我们能了解这些内容,手稿和古代遗址一起,诠释了那场劫难
-
It's kind of unsettling because we like to know what things are, but at the same time it's not really a big problem because as long as we know about the fact that a certain notion of literature exists in certain communities we can begin to do very interesting work precisely with that idea.
可能会有点让人不安，因为我们总想知道事物的定义，但知不知道,实际上问题不大,只要我们知道在特定群体中对文学有特定的认识,我们就能在这种认识上做文章。
-
Because we know as we go to infinity, even though the density gets smaller and smaller and smaller, we still have electron density very far away from the nucleus.
因为我们知道即使到了无穷远处，尽管电子密度会变得非常非常非常小，但我们仍然有一定的电子密度，无论离原子核多远。
-
This intuitively should make a lot of sense, because we know we're trying to minimize electron repulsions to keep things in as low an energy state as possible, so it makes sense that we would put one electron in each orbital first before we double up in any orbital.
这个直观上讲得通，因为我们知道尝试去最小化电子排斥力,从而尽可能的保持处于一个较低的能态,所以它讲得通,在我们在同一个轨道放入两个电子之前,我们首先把电子放入每一个轨道。
-
It makes sense to draw the wave function as a circle, because we do know that 1 s orbitals are spherically symmetric.
把波函数画成一个圆是有道理的，因为我们知道1s轨道是球对称的。
-
This should make a lot of sense, because we know that a hydrogen has 1 s as it's outer-most or valence orbital, so it can be filled up just with two 1 s electrons.
这也是很合理的，因为我们,知道氢只有，1，s，轨道,这就是它最外层的轨道或者说价轨道，因此只要两个，1，s，电子就可以将它填满。
