There you can actually do sort of substance analysis which you can't really do by conventional x-ray."

Remember, we don't do a one-to-one correlation, because p x and p y are some linear combination of the m plus 1 and m minus 1 orbital.
记住,我们不需要把它们一一对应,因为px和py轨道是,m等于正负1轨道的线性组合。
It's still 1, because you plus plussed the wrong symbol called X. So for now, take-away from this, don't do this.
它还是1,因为你自增的是那个错误的叫做X的符号,现在,拿走这个,不这样做。
I think it becomes 30 degrees for the freezing of water and 22.5 x 4, which I don't know what it is, 90 100 or something -- no, it's 90 I think.
我想水的冰点,应该变成了30度,22。5,4,我不知道是多少,大概100左右--不,我想是。
So this first little piece of code right here says, ok you give me 2 points, I'll create another 1 of these lists and I'll simply take the x, sorry I shouldn't say x, I'm going to assume it's the x, the x-values are the two points, add them together, just right there, the y-values, add them together and return that list.
好,为了来认识到这一点,让我们来看一个简单的小例子,在你们的课堂手册上,你可以看到我写了一个小程序,它假设我得到了,这些点中的一些,我想对它们做一些操作,例如我想把它们加到一起,那么这里的第一小片,代码的意思是,好给我两个点,我会再创建一个数组。
He still incurred -C because he ran and he also has a cost of |x-y| because he doesn't like Mr. Y winning.
他同样有-C的收益因为他参加了竞选,且他还有|x-y|的成本,因为他不喜欢Y先生获胜
I am hoping that if you learned your calculus, you learned about derivatives and so on by looking at x versus t.
我希望你们学习微积分时,通过观察x-t图来,学习导数等内容
How do I posit-- why do I believe in x-rays, even though I don't see them?
我如何证实,我为什么会相信X射线是存在的,尽管我压根看不见它
So what I've said so far is, a particle moving in time from point to point can be represented by a graph, x versus t.
到目前为止,我说过,一个质点随时间的连续运动,可以用一幅x-t图来表示
So what we would like to do is to describe what the object does by drawing a graph of time versus space and the graph would be something like this.
然后我们要做的就是描述这个物体的运动,通过画一个"x-t"图,画出来的图就像这样
But we don't have X-ray vision.
但我们没有X光。
That is x versus t.
这就是x-t图
Now in fact, this may come as a surprise to you, I don't have ESP, I'm not a character out of the X-Men, so you can't actually see brain waves emitting from my head, and my reasoning doesn't affect your reasoning.
事实上,这绝对是不可能的,我没有超能力,我也不是X-Men,所以你根本看不到我大脑发出的脑波,我的推理不会影响到你
It's reasonable because it's meant TMP for temporary purposes just to call it temp or T-M-P for short, X and I can define temp as -- why don't I set it as equal to X, initially, because now that I've stored X in a separate chunk of memory, I can now change its value and then I can say Y gets, not X, but temp, and so now I've actually swapped these values.
这是合理的,因为它是为,暂时的目的,只要叫它Temp或简称它为,我可以定义temp为--为什么我不把它设定为等于,最初的,因为现在我把X存储在一个单独的内存块中,我现在可以改变它的值,然后我说Y等于,不是X,而是temp,所以现在我交换这些值。
Mathematically complete problem is that you can find the function x of t by saying that the second derivative of the function is equal to -k over m times the function.
这个数学问题就是,你可以求出函数 x,只要令函数的二阶导数,等于 -k 除以 m 再乘以函数
You cannot answer that, even if I promised to move only along the x-axis, because I think...I don't want to pose this as a question, because I think the answer is fairly obvious to everybody.
即使我保证只在 x 轴上移动,你们仍然无法回答,因为我觉得...我不想将其作为一个问题,因为我认为答案是显而易见的
