And let's look at the final kinetic energy that we'd observe in this spectrum, which is 384 electron volts, so what is that third corresponding ionization energy?
然后让我们来看一下,在光谱中观测到的，最后一种动能，它大小是，384，电子伏，那么这相应的第三种电离能是多大？

Other times it behaves as a wave, and that is the way it helps us to think and rationalize what we observe.
另一些时候它更像波，而这是能帮助我们思考,和理解我们所观察到的东西的一种方法。

"This was the 40 percent decrease in risk. We did not observe an association for drinking three cups or less per day."

NO So that the more complete answer to the question is that no, we're never going to be able to observe that because of the uncertainty principle it's not possible to observe a velocity that's this slow for a macroscopic object.
所以这个问题的完整答案是，由于不确定性原理,我们不可能测量到这么慢的,宏观物体的速度，希望这个解释。

and he knew this the same way that we saw it in the last class, which is when we viewed the difference spectra coming out from the hydrogen, and we also did it for neon, but we saw in the hydrogen atom that it was very discreet energy levels that we could observe.
那就是,当我们看氢原子发出的光谱时，我们也看了氖气,但我们看到,氢原子能级是分立的，这些，在当时,已经被观察到了,他也都知道。

So it turns out that we can, in fact, use the energy levels to predict, and we could if we wanted to do them for all of the different wavelengths of light that we observed, and also all the different wavelengths of light that can be detected, even if we can't observe them.
事实上我们可以用能级预测,而且如果我们想的话，我们可以,对所有观测到的光的波长预测，也可以对所有探测到的光预测,即使我们看不到它们。

And that's somewhat inconvenient because we're working with wave functions, but it's a reality that comes out of quantum mechanics often, which is that we're describing a world that is so much different from the world that we observe on a day-to-day basis, that we're not always going to be able to make those one-to-one analogies.
这对于研究氢原子，很不方便,但这就是事实,而且在量子力学中经常会出现这种事实,那就是我们要描述的世界，和我们日常所看到的世界,之间的差别是如此之大,以至于我们不能，做出一一对应的类比,但幸运的是我们不用管。
