In other words, replacing the shortest distance between two points that we experience in a practical message, "literariness," as the formalists call it, or "poetic language," as they also sometimes call it and as the New Critics certainly call it, slows us down.
也就是说,实用语言以最短的距离,联系两点,而文学性,如形式主义者所称,或诗意的语言,他们有时也会这么叫,新批评派成员一定会这么称呼,使我们的理解速度慢了下来。
And we turned to a discussion of the unpredictability of death, -- the fact that because we don't know-- we can't predict--how much more time we've got, we may, as it were, pace ourselves incorrectly.
我们转而讨论死亡的不可预测性,因为我们不知道-,我们不能预测--我们还有多少时间,我们可能,可以说是,为自己定错了前进的速度。
And so if I have concerns, it is sort of more indirect directions I think economic growth is doing all right, it's doing quite all right, 8% and if it's not 9%, if it's 8% ,7% range that's very handsome economic growth rate that should not be weigh upon anybody's mind as a matter of concern.
如果要说我关心什么,那就是隐藏的经济发展方向,我觉得印度的经济增长很不错,增长势头良好,即便不是9%,也是7%到,这种经济增长速度已经很厉害了,这种情况谁都不应该,表示担心。
And then I could put a couple of plates and I could raster the beam so that when I am looking here,the beam goes back and forth about 80 times a second.
然后我放了两个感光片,我可以检测到光束所以,当我观察时,电子束以每秒80次的速度来来回回了。
And I have purposely made the arrow shorter to indicate that it has been slowed because we are going to argue its mass didn't change, so the only way to change its energy is to change its velocity.
我已经故意将这个箭头弄短,用来象征它变慢了,因为我们将证明它的质量没有变,只有它的能量改变了,也就是它的速度变了。
Conversely, if I knew the velocity of this object, I also know what time it is, provided I knew the initial velocity.
反过来,如果我知道了这个物体的速度,我也同样可以知道时间,只要初速度是已知的
Alright. So, since we have these terms defined, we know the frequency and the wavelength, it turns out we can also think about the speed of the wave, and specifically of a light wave, and speed and is just equal to the distance that's traveled divided by the time the elapsed.
好了,我们已经定义了,这些术语,我们知道了,频率和波长,现在可以来考虑,波的速度了,特别是光波的速度,速度等于它走过的距离,除以所用的时间,因为我们。
Here we go. Notice the tempo is slowed down a bit here also.
我们开始吧,注意速度,在这里也放慢了一点
So he's up to something here with this rate of harmonic change.
他在这里准备做一点什么,泛音的速度发生了变化。
Light travels basically a foot in a nanosecond. Simple rule of thumb.
光行进的速度是每纳秒一英尺,很简单的经验法则了。
That is the whole triumph of calculus is to know that by looking at the position now, the position slightly later and taking the ratio and bringing later as close as possible to right now, we define a quantity that we can say is the velocity at this instant.
这就得靠微积分了,通过了解它现在的位置,和一小段时间以后的位置,计算它们的比,再让时间间隔尽可能缩短,我们就定义了一个,被我们称之为瞬时速度的物理量
He reasoned then that the charge, since he could vary voltage continuously but got a discontinuous variation in velocity, his conclusion was that the charge must be discontinuously attached to the droplet.
他推断出电荷,因为他可以不断地改变电压,但是得出了速度是在不连续变化着,他的结论是电荷,是间断地依附于液滴上的。
The tempo here is very slow and he slows it down even more and then it just sits out there, this huge wonderful voice that he had, on the leading tone.
速度非常缓慢,经他处理后就更慢了,余音缭绕,他在导音上展现了洪亮,精妙的歌喉

Now, you can take this velocity, you can take this R.
现在 你已有了速度和 R
Then, in every situation where the body has an acceleration a, the location has to have this form, where this number is where it was initially, this was the initial velocity of the object.
