So, keep that in mind when we're talking about atomic radius, I'm not suddenly changing my story and saying, yes, we do have a distinct radius.
因此,当我们讨论原子半径的时候要时刻记住这一点,我并不是在突然改变自己的说法,说是的,我们的确有一个准确的半径。
Then later on, if I wish, I can establish a canon by saying certain texts have certain significance and those are the texts that I care about and want to read, but I can only do that if I can distinguish between meaning and significance.
而后来,如果我希望,我可以通过说什么来树立一个标准,比如说,一些作品有固定意义,因此我只关心只想读那些作品,但是我只有,能够分清意思和意义之后,才能那样做。
Now in this case, it's clear that I'm not only saying this function takes an input, I also have to give that input a name.
在这种情况,很清楚的,我不只是说明这个函数有一个输入,我还要给那个输入一个名字。
OK, the reason I'm saying this is, we have one class definition, is a cookie cutter, it's a template that's going to let us build versions of these things.
同一实例,好,我为什么要说这个的原因是,我们学习了类的定义了,这就像曲奇成型刀一样,它是个让我们建立不同版本的,这些东西的一个模板。
It is a much scarrier idea than saying I have this, I'm going to do it, I'm going to put it down there as opposed to being open to what may come and being uncertain whether that would be something good enough.
这和,我知道了,我要做这个,我想写这个,这种确定感相比,对可能的结果保持一种开放的心态,不知道,期待能否满足的未知感相比,更挑战一些。
Henry. Henry. So Henry is saying sure i don't have a dominated strategy.
亨利认为我们确实没有劣势策略
And when somebody else then attacks them, say, "Look, I think that what John was saying was a good point and here's how I think he should have defended his position," or what have you.
并且当其他人攻击他们时,你说听着我觉得约翰说的是个好点子,和这是我认为他应该怎样维护自己的立场“,或者你有什么。
It's worth saying a word about that, because I want to undermine any great confidence that you may have and what you can believe that scholars tell you, because we keep finding out how wrong we are about all kinds of things.
这里得说的是,我想给自信满满的家伙泼点儿冷水,你曾深信不疑的学者们告诉你的那些事,不断被发现,并在很多问题上都存在纰漏
So we can draw that for 1 s a, we can also draw it for 1 s b, and what I'm saying for the molecular wave function is that we have the interference between the two, and we have a constructive interference, so we end up adding these two wave functions together.
所以我们可以对1sa画出它来,我们也可以对1sb画出它来,对于分子波函数我要说的是,它们两者之间会干涉,这里我们有相长干涉,所以我们得到的是波两个波函数加起来。
Well one way you could do it is by saying 'if I have this one base pair difference then this sequence is going to be cut by a specific restriction enzyme that recognizes the sequence CTGAGGA'.
一种方法是通过考虑,"如果我有这个不同的碱基对,那该序列必然会,被特定的限制酶识别并切割,这个特定的限制酶能识别,CTGAGGA "
But there's an important thing going on here, if I in fact wanted to combine those into a string I should have told the machine to do that, and I can do that, by explicitly saying, take that, which is a number, then add it to that string.
但是这里有个很重要的事情,实际上想要把这些加到一个字符串里面去,我应该告诉计算机去做这个,我应该这么做,通过明确的输入,也就是把这个对象,一个数字,然后把它加到一个字符串里面去。
What we're really getting at is the idea of saying I want to have a way of grouping together information into units that make sense. So I can go back to one of those topics we had at the beginning, which is the idea of abstraction, that I can create one of those units as a simple entity, bury away the details and write really modular code.
组合成为有意义的单元,那么这就让我们回到,一开始讲的话题之一了,这就是抽象的概念,也就是我可以以一个简单的,实体的形式创建这样的一个单元,把具体实现隐藏然后写一些,真正模块化的代码,我们在以后的课程中。
That is basically saying, given some collection of data, I want to have again a looping mechanism, where now my process is, walk through this, the collection one element at a time. And for that, we have a particular construct, called a FOR loop.
现在我的过程就是,通过一个个访问这个集合中,的元素的方式,来遍历这个集合,为了达到这个目的,我们有一个特定的结构,成为FOR循环。
