OK. In the length of time it takes for the light to get from that bulb to the table, this machine processes two operations.
好,在灯光从灯泡到,桌子的这段时间内,电脑已经进行了两次运算了。
And I don't have to worry about these relative dimensions because we know from Marsden's calculations that, on the length scale that I have shown here, these would be just tiny little dots.
我们不必考虑,它们的相对大小,因为从马斯登的计算中我们可以得知,就从我现在给你们演示的这种相对距离来说,这些电子将只是一些很微小的斑点。
A gig is 10 to the 9, so it does two operations in the length of time it takes light to get from one foot off the table down to the table. That's amazing.
因此光行进一英尺的,时间内电脑可以,进行两次基本运算,这太神奇了。
So,as the vaccine was passed from arm to arm, it became less potent, and the length of protection that it would give you varied.
所以当疫苗从一个人传给另一个人之后,它的防治效力会减弱,它带给人的免疫期限也会改变
You can see from trigonometry and the length of the vector I'm going to call by A.
可以用三角的知识,然后我把矢量的模长记为 A
Well, this question mark becomes an O, this question mark becomes an O, and then the loop terminates 0 1 2 because it's iterating from zero to N so that's zero, 1, 2 and the length of the string is 3 so the loop terminates, but I remember that I needed to have this special sentinel value so I'm just going to put it there manually.
嗯,这个问号变成了,这个问号变成了0,然后循环结束了,以为迭代从0到N,那就是,字符串的长度是3,然后循环就结束了,但是我记得我需要这个特殊的标记值,所以需要手动的加上它。
It says if I want to get the length of a segment, going to pass in that instance, it says from that instance, get the start point, that's the thing I just found.
它的意思是如果我想要,得到一个线段的长度,首先要把这个实例传进来,然后对于这个实例,从开始点,取得x坐标,然后通过同样的操作。
er is a vector at each point of length one pointing radially away from the center.
r 是一个模长恒为 1 的矢量,方向沿半径向外
