It's very exciting, but if you think you know everything you don't need to learn, you don't belong to us. I always need to learn.
这很令人兴奋，但如果你认为,你什么知道，你不需要学习了，那么请你退出百度，因为人总是在学习。
-
You need some of it because some of it gets converted into molecules called phospholipids, and phospholipids are different.
但你也需要一些甘油三酯,因为它们可以转化成磷脂分子,而磷脂又各不相同
-
So if I try to rotate my 2 atoms, you see that I have to break that pi bond, because they need to be lined up so that the electron density can overlap.
如果我要试着转动两个原子，你会看到我必须要打破一个π键，因为他们需要连接起来,让那些电子能够重叠。
-
My argument must be wrong because it goes against the lesson of the class and the lessons of the class are gospel right, they're not wrong ever, so what's wrong with that argument? Yes, Ale Well because you have to be able to agree, you have to be able to speak to them but we aren't allowed to show our partners what we wrote.
这个说法肯定有问题,因为这和我们的结论刚好背道而驰,结论是绝对正确的,结论没错,那这个说法错在哪,艾尔,因为你必须要能够达成一致,你需要和他们谈判,但是我们不允许同伴看到我的选择

Probably, though, you wouldn't want to have the very youngest guys up front, because another thing you want is experience.
但是你也不会把最年轻的人放到前排,因为你需要的还有作战经验
-
You know, if you want to measure the potential energy of something in a gravitational field, you have to define the zero somewhere, right, because it's arbitrary. You can set it anywhere you want. It's the same with enthalpy.
你知道，如果你想测量重力场,中某种东西的势能，你需要，在某处定义一个零点，对吧？,因为势能的值是任意的,你可以把它设定在。
-
And so to deal with this last one, you need to develop style. All right?
因为为了对付最后的这种问题，你需要形成一种风格对不对？
-
You really need that because if you have only one copy of something, you don't have a backup; so, you can store the one copy separately.
你真的很需要这项发明,因为要是你只有一份的话，你就没有备份;,这样的话，你就可以将副本单独留存。
-
It's important to notice something when it's new because then you have to decide whether it's going to harm you, how to deal with it, to attend to it, but you can't keep on noticing it.
能够注意到新鲜事物的出现是非常重要的,因为你需要确定它是否会对你造成伤害，需要确定如何去处理这个新鲜刺激，但你不能一直去注意它。
-
Because you see, also motivation and energy-- you don't need research for that, you know that when you are feeling good, you have more motivation, you have more energy-- of course, there is a lot of research to back that up.
因为动力和精力-,不需要研究就能明白，你知道感觉好时，动力和精力更充沛-,当然有很多研究支持这一点。

And then there are some stupid syntax like curly braces and semicolons that initially are kind of annoying because you have to remember where all this junk goes.
还有一些像大括号和,分号之类的愚蠢语法,最初是很讨厌的,因为你需要记得它得放到哪里。
-
So that's just a little bit of a check for yourself, and it should make sense because what you're doing is you're calculating the difference between energy levels, so you just need to flip around which you put first to end up with a positive number here, and that's a little bit of a check that you can do what yourself.
所以你们总要确保括号，离得这项是正的，这是你们自己,可以做的检查，这事很有道理的，因为你们做的是计算能量差,所以你需要调整顺序来保证一个正数，这是你们自己可以做的检查。
-
So you don't want to put in a negative energy, that's not going to help you out, you need to put in positive energy to get an electron out of the system. So that's why you'll find binding energies are always negative, and ionization energies are always going to be positive, or you could look at the equation and see it from there as well.
因为这对电离没有帮助,你需要一个正的能量,使得电子脱离这个系统,这就是为什么你会发现,结合能总是负的而电离能总是正的,或者你们看这个方程也可以发现这一点。
-
It's always a good first approximation, because you need to start somewhere in terms of drawing Lewis structures, but then if you go and figure out the formal charge and you just have lots of charge separation or very high charges, like a plus 2 and a minus 2 and a minus 1 all different places in the atom, what it should tell you is maybe there's a better structure.
它总是一个好的第一近似，因为在画路易斯结构的时候,你总需要一个起点，但是如果你在算出形式电荷之后,发现有很多电荷分开了,或者说有很高的电荷，比如有一个正二，一个负二，还有一个负一1,在原子的各个地方，这应该就是在告诉你,或许还有一个更好的路易斯结构。
-
And also I wanted to mention in terms of checking your Lewis structures, regardless of what they are, you should always go back and I had 10, and then count 2, 4, 6, 8, 10, because you always need to make sure you have the same number of valence electrons that you calculated in your actual structure.
我还想提一点关于检查,你的路易斯结构的建议，不管它们是什么，你总是应该回去检查一下,我有十个，然后数一数，二，四，六，八，十个，因为你总是需要确保实际价电子的数量,与你在结构中算出的数量相等。
-
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.
我们依然可以得到上面的信息,即使我们所知道仅仅是这个键更强，我们不需要去看这个图，因为事实上如果你有一个更强的键，这也就意味着你有一个更短的键-,这两点是互相关联的。
-
I print out -- and this is only wrapping - because of the big font -- I print out, "I demand that you give me a positive integer."
我打印出来--这个字符相互覆盖了,因为用的是大字体-,我打印：“我需要你给我一个正整数“

Now, recruiting is tremendously important because you need to have a certain number of settlers to make the settlement viable.
招募是极其重要的,因为你需要有一定数量的移民,来维持居住地的运转
-
I don't need to tell you the volume here, because you've got enough information to calculate the volume.

since all the information is in the current price, you don't have to worry about whether it went up or down yesterday, to decide what it's going to do today.
因为当前价格代表了所有信息，你就不需要去考虑昨天股价,是涨了还是跌了，再去判断它今天的价格会怎么变化。
-
So, I need to tell you how you're doing the expansion, because that's going to tell you how much energy you're wasting during that expansion.
所以我需要告诉你,膨胀是如何进行的，因为这会告诉你,在这次膨胀中,浪费了多少能量。
-
And b, they have what's called a low expense ratio since they're easy to implement, you don't pay anyone to be brilliant to implement if for you.
但是他们的费用比率很低,因为这种做法很容易，你不需要,有多聪明就能去实施。
-
You also need to bring a calculator, we'll be solving problems that involve calculations.
你还需要带一个计算器，因为我们会需要解一些涉及计算的题目。
-
Some customers want to use your safe because safes are hard and expensive to get and some -and then you've got all this gold, so you might as well lend it out.
顾客需要使用你的保险箱,因为对个人而言保险箱既昂贵又难以获得,这样你就拿到他们的金子,然后你可以把金子借出去
-
What is this? This is a wonderful piece of abstraction. It is saying, you don't need to know squat about what's inside the body of this function. You don't have to worry about the parameter names, because they're going to be preserved, you don't need to worry about how I'm doing it, this tells you how you can use this, in order to use it correctly. Of course, I can then close it off, and off we go.
但是这能告诉你一些信息,这是什么？,这是一段完美的抽象,它的意思是你不需要知道,这个函数的内部构造，你不必担心参数是否重名，因为它们已经被预存了,你不需要担心我如何使用它,它告诉了你你该如何操作，从而正确的使用它，当然我也可以把它关掉。
-
That's because, at the end, if- -suppose you're one month or two months away from the payoff of the mortgage, you don't have any balance left, so the interest that you're paying is -hardly any balance left--is very low and so you're payment is paying off principal, mostly.
这是因为,在最后,如果,假设你还剩1到2个月,就可以还清抵押贷款,那么剩下的贷款余额就很少了,因此你所需要付的利息,将会非常少,因为贷款余额几乎为零,此时你偿还的就主要是本金
