And so one of the things we'll look at today is how can we leverage an algorithm, how can we implement an algorithm that at least at first glance the second time we've now seen it feels so obviously better.

I want you to look at this picture, read the little bit about gene - control of gene expression - that's in the book, know that it's a big topic, that we're not going to talk about it except we're going to talk about some examples where control of gene expression can be exploited in order to treat diseases, for example. So I'll see you on Thursday.

We can know this information even if we just knew that the bond was stronger, we wouldn't need to look at a graph here, because it turns out that if you have a stronger bond, -- that also means that you have a shorter bond -- those two are correlated.

And so when you start to poke around the puzzle pieces, you see that it can say things, we'll see movement in just a moment and sound and so forth, but at the end of the day, this is just like the program we used a moment ago for the sock exercise where we just hold Philip a step after step after step, do this, do this, do that, and yet, here too, we already see an opportunity for that thing we called the loop.
如果你认真看下这些拼图，你会发现它都是一些移动，并发出声音的功能块,就像我刚才的,练习程序一样,我们让飞利浦做这个动作，做那个动作，跟这里的情况一样，我们已经看到了称为循环的东西。

So, that's the difference in thinking about different types of ionization energy, so it can get a little bit confusing with terminology if you're just looking at something quickly, so make sure you look really carefully about what we're discussing here.

-
Now, the one that we're most interested in ANS is the one where, in fact, it gets out ANS, so you see down here in the code, there's a spot where it's going to return the value of ANS, which is what we want, right? That's the thing that holds the value that we intended to have.
现在我们最感兴趣的是这个,事实上它返回的是，所以你看这段代码,在这里返回ANS值,也就是我们想要的,对吧？,它就承载了我们想得到的值。

On line 2, we're gonna induce what's called a loop, so do you wanna go ahead and Philip henceforth you get to stare, stare at the awkwardness.

But when you start writing programs, especially when we get to web-based stuff where you want -- to check the user's input -- is it valid, is it an email address, -- and all these different scenarios -- it's actually often useful to be able to just enumerate them or rattle them off using this switching construct instead.
但是当你看是写程序时，特别是当我们,使用基于网络的东西，你想要,检查用户的输入-,它是合法的吗？它是不是一个电子邮箱地址？,所有的这些场景-,实际上它常常是有用的，当你用枚举结构列举它们,或者用它来快速地来说出它们。

I couldn't have told you, for example, if we look at a phosphate group, that that's going to be incredibly important in DNA, that it's also an incredibly important group when you're dealing with proteins and whether you're turning the function of a protein on or off.
怎么和化学反应相联系起来的，更不记得其它我更不感兴趣的规律,我不能告诉你，如果我们看磷酸盐,它们对于构成DNA十分重要,也是构成蛋白质的重要组份,它是否能打开或关闭一个蛋白质的功能。

Oh--but if you can meet with our teaching fellows over there, they're gonna ask the legal department to see you next so Alright, I think we're all set.
