So the probability of having an electron at the nucleus in terms of probability per volume is very, very high.

在单位体积内发现,一个电子的概率非常非常大。

So, if we do this calculation for an electron, saying it moves at 10 to the 5 meters per second, then what we end up with for a wavelength is 7 times 10 to the -9 meters.

如果我们已知电子以，10的5次方每秒的速度运动，那么做一个计算,可以得知它的波长是,7乘以10的负9次方米。

in the context of a web page. And increasingly that is where the human computer interaction is, and so will you be empowered by terms and not to just to make a website per se but to make an application, something that's of interest to you, something that solves problems, something that lets you tell someone through the most electronic means possible that you saw them somewhere on campus.

以网页内容的形式表现出来,人机交互的运用将越来越多，而且你将学会编程,不仅能制作网站，还能做出应用程序，一些你感兴趣的东西，一些解决问题的手段，还有一些可以让你通过使用,现有的电子手段来分辨出,校园里面看到的一个人的东西。

If your plan is to accelerate a 3 kg mass with an acceleration of 2 meters per second, you better have a rope that can furnish that force and it can take the tension of 6 Newtons.

如果你想用 2 米每秒平方的加速度,去拉一个 3 千克的物体,那么你就需要一根能提供拉力的绳子,并且它能够承受 6 牛的张力

I have to change the prototype of this function to say that swap no longer takes an int per se or another int per se, but rather it takes two pointers, two ints, and in fact, it's on the very last page if you're still flipping.

我改变了这个函数的原型,来说明swap不再携带那两个int数本身，而是携带两个指针，两个整型数指针，实际上，它是在最后那页上。
