And then of course as soon as my son got a look at all of the stations here he just made a beeline because he wanted to start building.

So we'll start to look at molecules and we'll see if we take two atoms and we fill in our molecular orbital and it turns out that they have more anti-bonding orbitals than bonding, that's -- a diatomic molecule we'll never see.
我们要看开始看一看分子,并且我们会发现如果我们,取两个原子并且填入分子轨道,结果是它们的反键轨道,比成键轨道更多,这就是-一个我们不会看到的二元子分子。
And we have to start to look at other experiments to try to get at what is it about physical attractiveness ? that makes people want to pursue the relationship?
我们必须看看其他的实验,来揭开外表吸引力的真面纱,了解为什么它能促使男女双方继续交往?
And we'll start to look at how it's possible.
我们将探讨为什么是可能的。
If you start to look at food labels more carefully, what you'll find is some version of sugar, and if you find ose, o-s-e at the end of something, that means it's a sugar.
如果你更仔细地看看食品标签,你会找到许多类型的糖,如果你找到词缀"ose",以ose结尾的单词,那说明这是糖类
So, we'll start by taking a look at constructive interference, and another way to explain this is just to say again, molecular orbitals are a linear combination of atomic orbitals.
我们先来看一看相长干涉,另外一个解释它的方法就是说,分子轨道是原子轨道的组合。
Can I get you all to look at Game 1 and start thinking about it.
大家先浏览下游戏1 然后思考一下
OK. Having said that, let's look at doing some sorts. And I'm going to start with a couple of dumb sorting mechanisms. Actually, that's the wrong way saying it, they're simply brain-damaged, they're not dumb, OK?
我们来做些排序吧,我要开始处理一些愚蠢的排序机制,事实上,我说的不正确,他们就是没脑子,不是笨,发明出来后,他们就在不停的被挑战?
It's also important, once we start talking about molecules, to have a way to represent them, and also to be able to look at a shorthand notation for a certain molecule and understand what the bond is.
还有很重要一点是,一旦我们开始讨论分子,我们需要有一种表示它们的方法,而且能够从中看出,某些分子的简化符号,并得知键的类型。
Something I'll also point out as you see these dashed line that tell you where the individual molecular orbitals are arising from, as you get to higher and higher atomic numbers of molecules that you're making, it makes a lot more sense to look at a diagram when you draw these dotted lines in, because they can start to get a little bit confusing.
我要指出的是,你们看这些虚线,它们告诉你,每个分子轨道的起源是什么,当你的原子数,越来越高的时候,画出这些点线,使图更容易理解,因为现在开始变得有一点混乱了。
If you look at weight and risk of Type Diabetes you start to see something pretty interesting.
在体重和II型糖尿病患病风险的关系中,我们能得出更有趣的发现
