the best I can." Ohno could add to his Olympicsshort track speed skating medal total.

In which I said, you know, I didn't like the fact that things like plus are overloaded, because you can use plus to add strings, you can use plus to add numbers, you can use plus to add floats.
那个玩笑是这样的,你们懂得,我并不喜欢,加法被重载这样的事情,但是你可以用加法,来对字符串进行合并,你可以用加法来加数字。
As far as I can see,the best option for the body theorist at this point is to add--no surprises here--a no branching rule.
据我所知,肉体理论者最好的选择就是,毫无意外地,是加上一条无分支规则。
OK, I can certainly print out strings, but I can actually add strings together, and just as you saw, I can multiply strings, you can kind of guess what this is going to do.
当然我可以显示字符串,但是其实我还可以令字符串相加,如你所见到的,我可以令字符串相乘,你们可以想想答案是什么。
It is true mathematically, you can add two numbers, but you've got to ask yourself,"What am I doing as a physicist when I add these two numbers?"
在数学上它是正确的,你可以引入这两个常数,但是你需要问问自己,当我引入这两个常数时,这么做有什么物理意义
Julia, yes. I think I can also add, it's okay.
是朱莉娅,我想我还能补充一下。
Now, notice that if we accept this view to decide how well off I am, or somebody else is, you can't just add up the contents of the life.
请注意,如果用这种观点决定自己的幸福程度,或者其他人的幸福程度,你就不能单单把生活内容加起来。
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。
But I can add to this some number, like 96, that'll still have the property that if you take two derivatives, you're going to get the same acceleration.
但是我可以在后面加上某个数,比如96,经过两次求导你仍会得到,同样的加速度
To get any location in memory, to get to any value of the list, I simply have to say which element do I want to get, I know that these things are stored in a particular size multiply that index by 4, add it to start, and then it's in a constant amount of time I can go to that location and get out the cell.
取得列表中的任何一个值,简单说来,想要取得列表中的任何元素,我知道这些元素存在特定的大小中,把下标乘以4,加到start上,然后定位到内存单元,并取出值就是固定的时间了,好的,如果元素以固定大小存储。
I can write it explicitly. I can write it inside of a FOR loop. And we've started to add, and we'll see a lot more of this, examples of collections of structures so that we don't just have to do something that can be easily described as walking through a set of things but can actually be a collection that you walk through.
我可以明确的写出来,我可以把它在FOR循环的内部写出来,然后我们开始学习了add这个运算符,我们会在以后学习很多的,集合的数据结构的例子,这样一来我们可以进行一些,很简单的遍历集合的操作,我想要为大家指出的最后一件事情是。
If you want to add two vectors, you can add the arrows by the rule I gave you or just add the components of x of the two guys to get the component of the sum and likewise for the y.
如果要把两个矢量相加,你可以用我教给你们的箭头相接的方法,或者就将二者的 x 分量相加,得到和矢量的 x 分量,y 方向也是这样
