And if you are looking at a keyboard, we can predict in the real time very rapidly that beat your very single finger typing speed, exactly the letters you like to type and hit, therefore provide a communication mechanism that Christopher Reeve and those similar with him can benefit from.

如果你在看电脑键盘，你可以十分快速地,实时预知自己手指敲击键盘的速度，预知你想录入的字母，这样便为克里斯托弗·里夫,和其他你说熟悉的人提供了一种沟通机制，使他们从中受益。

This is very important,which is why I am doing it: "If we want to know how fast a human being can run, then it is no use to average out the speed of a "good sample" of the population; it is far better to collect Olympic gold medal winners and see how well they can do.

这话非常重要，是我作这个研究的原因：,“如果想知道人类最快能跑多快，那从好的样本中测出平均数是“,没用的;,而应该收集田径类奥运冠军的信息,看他们能跑多快。

So that way you can have an idea if, oh, I do really understand this but I'm a little bit slow, maybe I need to practice this one type of problem a little bit longer so I can get up to speed so I'm going to be able to get through all this in terms of the exam time.

这样你就可以知道，假设，噢，我真的懂这个，但是我的速度有点慢，或许我需要在练习这个类型的题目上,多花一点时间,这样我就可以提高自己的速度,可以全部做完,在考试规定的时间内。

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。
