It's really nice to meet you. You know, if you think... here, this is what I'm interested in.
见到你真的很高兴。如果你想……在这里，我就是对这个感兴趣。
-
So we haven't gotten to molecules yet, we're just talking about single atoms or single ions, but what's nice is just talking about this very straightforward principle of atomic radius.
我们还没有开始讲分子，我们仍然只是在讨论单个原子或离子，但它的好处在于可以讨论,这个关于原子半径的非常简单直接的原理。
-
This is boring. In fact, you can do some nice things to prove what is the class of functions you can compute with straight-line programs, and what you'd see if you did that is, it's not particularly interesting.
这很无聊，实际上，你可以通过做一些很有趣的事情,来证明你可以通过直线程序,来做很多功能，但是你也看到我们之前讲过的了，这不太有趣。

Again, it's a nice lens for asking yourself, what are the things that are most valuable to you?

So this is a nice succinct way of recording what was in the previous two tables.

If we do an experiment and we induce you to feel empathetic to somebody, we get you to feel what they're feeling, you're more likely to be nice to them.
如果我们做一个实验,我们让你对别人产生移情作用，让你感受到他们的感受，你很可能就会对他们很好。
-
That's not really what I think, but that's how disturbing it is when people talk, and very nice students who do not realize this often disrupt my line of thinking.
虽然那不是我的真实想法,但是在课上有人讲话确实很烦人,有些好学生也没有意识到这点,他们经常会打断我的思路
-
You need a hero to help you, and having that hero, encountering the other mind as helper, is what obviates the tendency, even in a nice guy like Tony, toward narcissism which is manifest in the "I," "I," "I" at the beginning of the story.
他能帮助你，有了他的帮助，就可以避免自我陶醉的趋势，即便是托尼这么好的人，也可能会有这一趋势,总是用，“我“，“我“，“我“来开头。

They build them, they do what if games, they play with them, and then they try and adjust them to get them right The nice thing here is, you can decide whether you believe momentum and see what it would mean, or not mean, etc.
他们实现建立程序，他们去做“要是“游戏，他们不断尝试，然后他们不断调整最终得到正确结果,最好的一件事就是，你可以决定你是否相信这个股票势头,看看它到底意味着什么或根本没有意义。
-
t What I now have, though, is a nice thing.
也就是。
-
I've simply added this one extra constraint, nice thing about thinking about it this way is it's easy to think about it, and what do you think I'll have to do if I want to go change the code?
我已经加上这个额外的约束条件，思考这种方法有件好事,那就是以这种方式来思考很简答,你认为我要是想？
-
So this is actually the most straightforward, so sometimes it's nice to end with the easiest concept, and that's what we're doing here.
这应该是最明显的一个，有时候用最简单的内容来结束是很好的，这也正是我们在做的。
-
Well partly this is just for fun-- this is what computer people sometimes do, intentionally or unintentionally but as also will see a really nice way to culminate the semester and frankly carve out a 10 hour block where you can bite off your final project's implementation surrounded by friends and the course's staff.
一部分只是因为好玩-,这是懂电脑的人有时会这么做，不管有没有意义,还有一部分原因是因为,以这种方式达到学期的高潮,并在朋友和这门课程教师的关注下,抽出10小时的时间完成最终的项目安装,是一件多么美妙的事啊。
-
But, I think what most of you, actually having MIT come to MIT, have probably realized is sometimes it's nice to major in a science, because you can't just pick up a reaction and do it in your kitchen on the weekend, where as you can sometimes join a book group and do that.
但我认为对你们大多数人来说,既然来了,可能已经意识到最好是主修一门科学,因为你不能在你,周末的时候在厨房里做化学实验,然后你就可以参加一个读书俱乐部。
-
So what's nice if you configure your command line environment appropriately is that things that are so-called executable, programs that you wrote like a.out happened to show up as green.
只要合理设置一下命令行环境,就可以看到，这些所谓的，执行文件,譬如a，out啊等，都会变成绿色。
-
All right. That actually seems like a really nice thing to have, and so let me show you what that would basically look like.
好了，那真的像一个,可以拥有的好事情，所以让我来给你们演示,那基本会是什么样子。
-
Yeah, good. So, they're actually helium atoms, helium ions. And this wasn't really important for the studies, it didn't matter that didn't know what they are but it's nice to kind of know now - that we do know what they were using.
氦粒子，这对他们的研究并不重要,他们并不需要知道它是什么,但我们最好知道,他们当时用的是什么。
-
Well, what's nice about this program is that there's just one function, main, so we don't need to draw the stack and get things all complicated.
这个程序的优点是,这里只有一个函数main，这样我们就不需要,画出堆，也不用那么复杂。
-
OK, so what have I done? I just added a little bit more now. I'm now running through a pair of loops. Again notice the encapsulation, that nice abstraction going on, which is what I want. Once I get to this stage though by the way, there might be more than one solution.
我现在运行了一对循环,再一次注意这个封装,抽象得很好，这就是我想要的结果,我按这种方式走到这一步的时候,可能会有多组答案。
-
And again, if I just run this, just to show that it's going to do the right thing, it says enter base, I'm obnoxious, it says oops, wasn't a float, so we'll be nice about it and I enter a height, and it prints out what I expected. I just concatenated those strings together, by the way, at the end.
我再来运行下看是不是做对了,提示输入底，噢，它提示说不是浮点数，我很高兴，然后我输入一个,浮点数作为高度显示结果和我预期的相同,顺便说一句,我只是在最后把这些字符串连接起来了。
-
What we're proposing here is that you take a nice low energy s electron and move it into a higher energy p orbital.
我们这里说的是,你把一个低能s电子,移到高能p轨道里去。
-
So let's do a sample calculation now using this Rydberg formula, and we'll switch back to emission, and the reason that we'll do that is because it would be nice to actually approve what we just saw here and calculate the frequency of one of our lines in the wavelength of one of the lines we saw.
让我们用Rydberg公式,做一个例题，我们回到发射上,这么做是因为这样,可以用我们看到的波长,来验证我们计算的频率。
