That's the lesson I try to remind myself of every day; we have an equal vote with all these other species on this planet."

which I just did there, -mystring in fact, let me type it in-- mystring, with an equal sign, which is saying, assign or bind to that name the value of the following expression.
也就是这里我做的,实际上,让我输入,然后是个蹬好,意思就是说,把这个名字绑定到,后面表达式的值上去。
Ever since this was first proposed, there has never been any observations that do not coincide with the idea, that did not match the fact that the probability density is equal to the wave function squared.
从未有,任何观测,与它相抵触,从没有过,波函数的平方不等于,概率密度的情况,关于马克思,波恩。
"This situation in which you have got three parties with equal shares of the vote really closely tied to the performance of the third party in the debate is absolutely unprecedented in British politics, we have never seen a situation like this."

To be equal to the world is not something that I came up with just now.
与世界相媲美这种说法,不是我刚刚想到的。
I think it depends on whether the list is odd or even in length. Actually, that's probably not true. With one, it'll probably always get it down there, but if I've made it just equal to two I might have lost.
是奇数还是偶数,事实上,这是不正确的,如果最后剩下一个,那可能得到了结果,如果剩下两个,可能错了,所以,首先我们要格外。
The way to understand the big three is with the phrase "all other things being equal."
我们理解的前提,是假设其他因素相同“
Socrates is not saying that men and women are the same in every respect, he says, but equal with respect to competing for any job at all.
苏格拉底不是在说,男女在每一方面都相同,他想说的等同,是指在任何工作职位的竞争上。
So, he has got to at least try to be equal with the guy who's furthest on this side, and same with the guy on the other side.
所以,他至少要和他这一侧,最远的敌军平齐,而敌方亦然
We call an instrument of the U.S. Treasury with a maturity less than or equal to one year--we call that a bill and they used to be the only discount bonds issued by the U.S. Government.
我们把期限小于或等于一年的,国库券品种称为短期国库券,它们曾是美国政府,唯一发行的贴现债券
So I differentiated this object, this is my first derivative and I set it equal to 0 Now in a second I'm going to work with that, but I want to make sure i'm going to find a maximum and not a minimum, so how do I make sure I'm finding a maximum and not a minimum?
这样我就对它求出导数了,这是一阶导数,令它等于0,一会我们就要计算了,但我先确定一下是最大值还是最小值,我怎么确定是最大值还是最小值呢
Well, this block here on the left that I came counter counter=0 up with arbitrarily sets a variable called counter equal to 0 and then it forever says that counters value 1 and then it changes the counter by 1.
大家看一下左边的这一段代码,其中有一个随便定义的变量,它会一直显示counter的值,每显示一次,counter加。
Therefore, from experiments, u is only a function of temperature for an ideal gas, H and therefore from these experiments, 0 we come out with delta H dH/dp is equal to zero.
因此,从实验可以得出,对于理想气体u只是温度的态函数,因此从这些实验中我们得到Δ,偏H偏p等于。
Knowing that, I'm going to say, OK, how many pigs are there, well that's just how we're, however many I had total, minus that amount, and then I can see, how many legs does that give, and then I can check, that the number of legs that I would get for that solution, is it even equal to the number of legs I started with, ah! Interesting. A return.
它将给我返回头的总数,知道了这些之后我可以说好了,有多少猪呢,无论有多少组鸡的数目,我只要用总数减去那个值,之后我就可以知道一共有多少条腿,然后再把这个值和题目中的腿数相比较,看它是否等于一开始的腿数,啊!真有趣,有一个返回值。
And then if we think about 3 s, 0 we want to start with 3, we subtract 1, again l is equal to 0, so minus and we have two radial nodes.
我们从3开始,减去,同样的l等于,所以减去0,我们有两个节点,这应该。
OK? You can take a quick look at it, a even with the wrong glasses on, it says if a 1 sorry, b is equal to 1, a I'm just going to return a.
你们可以快速的过一遍,它是这么写的:如果,对不起,是b等于,那么就直接返回。
Yup, so one total node, 2 minus 1 is 1, and that means since l is equal to 1, we have one angular nodes, and that leaves us with how many radial nodes?
一个节点,2减去1等于1,因为l等于1,我们有一个角向节点,那剩下径向节点有多少个呢?
In C and most programming languages, if you need greater than or equal to, use greater than and then right next to it with no space put equal to, and that conjures up the same idea.
在C和大部分的编程语言中,如果你需要表示大于等于,在“>“号后边加上一个“=“,中间不要空格,那使我们联想到同样的想法。
So this is our final equation, and this is actually called the Balmer series, which was named after Balmer, and this tells us the frequency of any of the lights where we start with an electron in some higher energy level and we drop down to an n final that's equal to 2.
把2代入到这里,所以得到1除以,这就是我们最终的方程,这叫做Balmer系,以Balmer名字命名的,它告诉我们从高能级掉到n等于2的,最终能级所发出光的频率。
We're going to differentiate with respect to q1, the thing we're trying--our control variable, the thing we're trying to maximize the thing with respect to and set it equal to 0.
对q1求导,q1是控制变量,也就是我们想要求出的最大值,令它等于0
Take these two equations, put an equal sign between them, replace this PR throughout with X, I'm going to have one equation and one unknown and that even the math phobics in the audience did in high school.
在这两个方程中间加个等号,将这里的Pr换成X,就会得到一个等式和一个未知数,剩下的问题,大家高中的时候就该回做了吧
And what he came out with when he did some calculations is that there's the radius that he could calculate was equal to this number a sub nought, which is what we call the Bohr radius, and it turns out that the Bohr radius happens to be the radius most probable for a hydrogen atom.
等于这个a0的值,我们叫它波尔半径,而,波尔半径恰好是,最容易,找到电子的地方,我们对波尔模型,不做过多的解释,这是因为。
