So, Marsden came up with the model, and as you go through 8.02 and you understand electrostatics and electrodynamics, you'll be able to do this analysis.

后来马斯登提出了这个模型，就像你们通过8。02的考试一样2,你们学过了静电学和电动力学，你也能做这些分析。

So you can think about how these 2 things combined are going to be electronegativity, which is a measure of how much an atom wants to pull electron density away from another atom.

因此你可以想象出,这两样性质合起来就是电负性，也就是一个度量，关于一个原子,有多希望把另一个原子的电子密度拉过来的。

You see the difference in electronegativity, square it, multiply it by one-quarter and raise that to the power e.

你看到了电负性的差异，开方，乘以四分之一,在移到e上去做指数。

Well, if you're implementing a computer that needs to represent information now all you need is something like electricity which can be on or off, on or off.

好吧，如果你正用一个电脑,来表现表达传递信息的功能,你就需要,像电开关一样的物体。

So, that process happens fast but you also need this neurotransmitter release and activation to happen fast so that you can have rapid activity.

所以 电传递过程很快,但你仍需要神经递质的,快速释放和快速激活,以便使你快速活跃起来

If you have to put the guy's hand on it, you're less likely to kill him.

如果你要把被电击者的手放在上面，你电死他的可能性会降低。

If you look at the electrical force, the force of electricity, proton and electron or something, it's not proportional to the mass of either object.

如果你考察电作用力,即电现象产生的力,质子啊,电子啊,或者其它什么东西,这种力不和物体的质量成比例

if we have a very electronegative atom within a certain molecule, what you'll actually find is that it does affect how the molecule is going to take place or take part in different chemical or biological reactions.

如果在某个分子中有一个电负性很高的原子，你会发现它确实会影响到,这个分子所起的作用,在不同的化学反应或者生物反应中时。

If you look at the electronegativity difference 73 for sodium iodide, it is 1.73.

如果你看到电负性之差,对碘化钠来说，是1。

You bring somebody in the sleep lab, you put electrodes on their scalp and you see what these-- what sort of electrical activities you get in the brain.

把人叫来睡眠实验室，把电极贴在他们的头皮上,你就能看到-,他们有什么脑电活动。

You don't need a light switch or a light bulb or an iPhone app to turn something on or off.

你不需要一个电灯开关,或者一个电管,或者打开关闭一个iPhone应用程序。

And as a result we can look at those factors and think about what is the perfect situation for making somebody do something like this and the perfect situation not to.

所以我们可以根据这些因素,想出什么样的情况,最有可能让你电死一个人,什么样的情况最不可能让你电死一个人。

But you need to be able to predict what kind of properties a certain atom's going to have within a molecule, whether you're talking about something, for example, that's very electronegative, or something that is not electronegative at all, it is going to make a difference in terms of thinking about how molecules are structured and also how they interact with other molecules.

但是你需要能够预言，什么性质,某个原子在分子中能够具有，无论你讨论的是哪一种情况，比如，它有很高的电负性，还是它根本没有电负性，都将会产生影响,对这个分子的结构,以及与其它分子相互作用的情况。
