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

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。
-
for he meant actually that we will never observe gravitational waves.
他的意思其实是我们永远无法观察引力波。

"Nobody else has been able to observe, with the detail that we can, the infrared emission from galaxies."

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 this is important because it means that since we cannot observe, we cannot talk about individual electrons.
这很重要,因为这意味着我们不能观察，不能谈及单个电子。
-
We can't observe souls.
我们无法看到灵魂
-
We see his conflicting emotions both to see and not to see, a sense that he wished to observe and yet he is at, in some ways, at war with himself, knowing to gawk, to stare at this sight.
我们看到他的冲突情绪,在看与不看之间打架，一种他希望观察的感觉,但他某方面，也在和自己战斗，明白自己瞪着这景象时会瞠目结舌。
-
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。
-
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？
-
And an electron is something where, i n fact, we might be able to, if we calculate it and see how that works out, actually observe some of its wave-like properties.
如果我们对电子做计算,并且知道如何算出来的,那么我们是可以观测到,电子的一些波动性质的。
-
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。
-
All right, so we can, in fact, observe individual lines.
好的，事实上我们可以看单个的谱线。
-
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。
-
We don't directly observe souls with our five senses.
我们无法通过五感直接观察到灵魂
