• What I want to do is get you to appreciate the unique perspective that you will get from studying solid-state chemistry.

    我要做的是,让你们,欣赏领会到它独特的远景,在学习固体化学的过程中。

  • I said at the core blitz that one of the things I'm going to try to do is introduce some things from beyond chemistry. So, let's see what the Bard had to say about nomenclature.

    我曾在核心闪电战上说,我想做的意见事情就是介绍一些东西,出于化学,也高于化学,所以,我们看看巴德对命名法是怎么说的。

  • Depending on what kind of chemistry you go in to, you might accidentally memorize parts of the table, which is fine, but what you really want to know how to do is know how to use the periodic table.

    取决于你今后从事哪个方向的化学研究,你可能会不经意地记住周期表的某一部分,这就够了,但是要注意,你真正需要知道的是如何使用元素周期表。

  • some chemistry class will show up in here, and someone will wonder what that is, and Barth will have done his work, or we will have done Barth's work for him. Now, let me ask you another question. Who is the narrator of "Night-Sea Journey"?

    这里将会上化学课,有人会想,这到底是什么,巴斯将完成他的工作,或是我们将为他完成工作,现在,我来问你们第二个问题,《夜航》的叙述者是谁?

  • What we are seeing here is a big transition from just experiment and documentation to modern chemistry.

    我们见证了一个很大的过度,从只是实验和,文件材料到现代化学。

  • So we can think about something I mentioned last time, which is when we're thinking about chemistry and what's really interesting in terms of chemical reactions, it's mostly valence electrons we're talking about, those are the ones that tend to be involved in chemical reactions.

    我们可以考虑一下我上次提到过的一件事,那就是如果我们讨论化学,以及什么是化学反应中,真正令人感兴趣的东西,我们讨论的几乎都是价电子,它们才是在化学反应中,真正起作用的部分。

  • But what really happens is as you go on in chemistry, you draw so many of these you can just draw them without following the rules.

    但是随着你在化学上的深入,你会画很多路易斯结构,以至于你可以不用管这些规则就能直接画出来。

  • But instead in this chemistry course, I will just tell you the solutions to differential equations. And what we can do is we can start with some initial value of r, and here I write r being ten angstroms. That's a good approximation when we're talking about atoms because that's about the size of and atom.

    但在这个课里,我会直接,告诉你们微分方程的解,我们可以给距离r一个初始值,我这里把r取10埃,当我们讨论原子时,这是一个很好的近似,因为原子的尺寸。
