If I am an inertial observer, another person moving relative to me at constant velocity will also be an inertial observer.

Right, this makes a lot of sense because if the entire atom was made up of nuclei, then we would have 100% probability of hitting one of these nuclei and having things bounce back.
因为如果整个原子,都是原子核,那我们就有100%概率,撞到一个原子核并被弹回来,所以如果我们。
And it turns out-- a little teaser for our security discussion as time passes that a lot of the times when software is compromised and you download Photoshop like a cracked version of Photoshop or something like that.
这对于即将讨论的安全性问题来说,只是一个小插曲,随着科技的发展,很多时候,如果工具受损,你会下载到一个版本不全的,或其他类似的东西。
because you read the Bill of Rights, for example, The Declaration of Independence, citizens have a duty to put a new government if it is not serving well the people.

所以,如果因语言,在你之前就存在,而它就显得枯竭,如果一切都已经被说过,如果已没有新的情节可供创造,如果世界一直充满陈腔旧调,你如何能够用它们,呈现出一个崭新的体验?
I mean, if the energy is lower to occupy a smaller volume, then if I have this room and a bunch of molecules of oxygen, and nitrogen and what have you in the air, and there are weak attractions between them, why don't they all just sort of glum together and find whatever volume they like.
我的意思是,如果占据小的体积会使能量降低,如果我有这样一个空间,和一些氧气,氮气和其他空气中有的气体,并且分子之间还有微弱的相互作用,为什么他们不黏在一起,然后占据他们所想要占据的体积。
If one were faced with starvation, then seeking out fat as we discussed before, is a pretty good idea, but if one is not deprived of calories, then having fat may not be so helpful.

If we had been thinking -- and some of us may well have been thinking and we were right to think provisionally -that Satan was a character that we could actually identify with, if we had been thinking that Satan was in any way a perfect character with some sort of justifiable claim -these thoughts are now being corrected by the means, by the mechanism, of the simile.
如果我们在思考--有些人已经在考虑这些问题,我们的确应该暂时想一想,-撒旦是一个的确可以,如果我们想过撒旦是,一个应当被公正对待的完美的角色的话,-这些想法目前已经得到了,这个机制和比喻的纠正。
They carry a potential, that is, if you could - if you had a tiny, tiny electrical meter, you could one put one electrode on one side of the cell membrane, on the extracellular side and one on the intracellular side and measure, you would measure a potential difference; just like a battery you would measure a potential difference.
它们带有电势,就是说,如果你能有一个足够小的电位计,可以把一个电极放在细胞膜一侧,假设放在细胞外的一侧,另一个电极放在细胞内侧并测量,你能测到一个电势差,就像电池那样能测到电势差
So if you run into a problem set that just, you don't get, all right? Seek help. Could be psychiatric help, could be a TA. I recommend the TA.
所以如果你碰到了一个,你不懂的问题,好么?求助,可以是精神科,可以是一个助教,我推荐助教。
If a person has the basic concept down, regardless of numerical errors, if the person has the basic concept down, he or she must get at least five out of ten.
如果一个人有一些基本的概念,不管一些数字上的错误,如果他有基本的概念,至少都能够得到一半的分。
I just want to remind you, if I wanted to, for example, type in an expression like that, notice the syntactical form, it's an expression, a number, followed by an operand, followed by another expression.
我想要提醒下大家,如果你想要,例如,输入一个这样的表达式,注意语法形式,这是个表达式,一个数字,后面是一个运算对象,后面是另外一个表达式。
So if we take a look at nitrogen here, what you'll notice is we have thre available for bonding, - and we already have our lone pair -- one of our orbitals is already filled up.
如果我们看一下氮原子,我们注意到我们可以成3个键,我们已经有一个孤对-,其中的一个轨道已经被填满了。
If you have some plain text, some message that you want to send, well, you can encrypt it or you can scramble it using a key, a secret key, which might be a physical machine like the Enigma 13 or it might be a number like 13.
如果你有没有加密的文本,你想要寄送的一些消息,你就可以加密它,或者你可以用一个密钥使其变得混乱,那就像一个英格玛的物理装置,或者他就是一个数字。
If you had one negative number in it, then the product would be a negative number and, if you took a root of that, then you might get an imaginary number.
如果这当中有一个负数,乘积就会变成负的,如果你对一个负数开根号,你就会得到一个虚数
The finding is that if your race or your group has a negative stereotype associated with it in any particular domain, being reminded of it serves as a stereotype threat and hence damages your performance in all sorts of domains.
他们发现如果你的种族或群体,跟一个消极的刻板印象有关,随便在什么领域上,如果别人在你面前提前,就足以构成刻板印象威胁,从而影响你在这个领域上的表现。
So, I've never heard the click-click-click-click-click, and we might bring a Geiger counter in here some time later in the semester so we can check all of you out, and hopefully we won't hear any when we do that either.
但我知道如果,你听到哒哒哒的声音,就表明你有麻烦了,我从来没听到过哒哒哒的声音,也许以后我可以带一个,来课堂上检测你们每一个人,希望我们不会听到哒哒哒的声音。
You know, if you're wandering through Harvard Square and you see an out-of-work Harvard grad, they're handing out examples of square roots, they'll give you an example and you can test it to see is the square root of 2, 1.41529 or whatever.
你知道,如果你从哈佛校园里穿过去,你看见了一个失业校友,正在派发平方根的示例,他们会给你一个例子,而你会检查2的平方根是1。41529或者别的什么。
- If you eat these raw, which they do in many places around the world, if you eat a bitter one, you could, in fact, get enough cyanide to kill you.
如果你生吃它们的话,它们在世界上的很多地方都存在,如果你吃了一个苦的根,可能,实际上,它所含的氰化物的量足以令你死亡。
If you're not updating some variable by incrementing it or decrementing it -- if you're not changing anything, presumably the conditions are never going to evaluate to false or the opposite, so you're just going to have an infinite loop, which might be your goal, but odds are it's not.
如果你不通过增加或减少它来改变一些变量,-如果你不改变什么,大概那个条件永远不会变成错误的,或相反的,所以你将得到一个无限循环,那可能是你的目标,但可能也不是。
So if you're coming from prior background, your code might work a little differently on a different system if you don't use those flags.
如果你来自一个先前的背景,如果你们没有使用这个版本标志的话,在一个不同的系统中,你的代码可能运行地不太一样。
So, if we're talking about five different orbitals and we're talking about a ground state atom, we know that we just need to start at the bottom and work our way out up.
因此,如果我们要讨论的是,五个不同的轨道且是属于一个基态原子的话,我们知道,我们只需要从最低的轨道,开始一个一个往上找。
If I look for, say, minus 1, you might go, gee, wait a minute, if I was just doing linear search, I would've known right away that minus one wasn't in this list, because it's sorted and it's smaller than the first elements.
如果我要查找-1,你可能要怒了,呵呵,等一等,如果我用的是线性查找,我不会知道-1不在这个列表中,但是列表是排好序的,1又比第一个元素小。
