And again, this points out something I wanted to me-- I mentioned last time, list can be heterogeneous, in the sense that the elements can be multiple different types.
这儿又指出了一点我想要告诉大家的,我上节课也提到了,就是数组是多相的,也就是说元素可以是多种类型的。
But yeah, it's kind of grown. I think maybe in last 10 years, it's grown out of control.

But it turns out that technologies like airplanes, which were developed in the last century, have become integral parts of medicine.
但像飞机这样,在上世纪发展起来的技术,确实已经成为医学不可分割的一部分
Another thing to point out in these two graphs is that we do have nodes, and we figured out last time, we calculated how many nodes we should have in a 2 s orbital.
另外这两张图上要指出的是,我们可以看到节点,上次我们知道,我们算了2s轨道有多少个节点。
If there was a time to go too fast it was probably last time, because it turns out this is something that's covered well in the textbook, so it's covered in chapter six of the textbook.
如果真有哪次讲得太快,可能就是上次,因为这些内容,已经在课本上写得很清楚了,就在课本的第六章
The last thing I want to point out, in this passage from here to the end of the chapter, is the way that Haze's senses are described.
对于这段文字,从这里到本章末,我想指出的最后一点是:,描述Haze感觉的方式。
One of the real surprising findings in my field over the last ten/twenty years has been that the acquisition of sign languages has turned out to be almost exactly the same; in fact, as far as we know, exactly the same as the acquisition of spoken languages.
过去的十到二十年间,在我的研究领域里最令人吃惊的发现之一就是,各种手语的获得过程,被证明几乎是完全相同的,实际上据我所知,和口语语言的获得过程是完全相同的
God whips out the old soul, destroys it, puts in a new one with maybe souls only last for a minute and a half.

So there are two electron configurations in the n equals one shell, if we follow according to the selection rules that we spelled out last day.
如果根据上次课,我们阐明的原子光谱选择定则,我们就会知道在n等于1的那一层,有两种电子图像构型。
So if you flip the info page over on the back here, what you'll see is the periodic table, this is the same one that I've handed out in the last two lectures - the periodic table without any electron configurations.
将这张纸翻过来,你可以看到一个元素周期表,这与我们前两次课发过的,是一样的,-没有任何电子排布的周期表。
and he knew this the same way that we saw it in the last class, which is when we viewed the difference spectra coming out from the hydrogen, and we also did it for neon, but we saw in the hydrogen atom that it was very discreet energy levels that we could observe.
那就是,当我们看氢原子发出的光谱时,我们也看了氖气,但我们看到,氢原子能级是分立的,这些,在当时,已经被观察到了,他也都知道。
