What I want to look at first is the suggestion that somehow, at some level, nobody really believes they're going to die at all.

现在我想要考察的是这个说法,不管怎样，在某种程度上，没有人真正相信他们会死。

And we don't have all the answers to these questions but what we've found so far by studying the cerebellum parallels in many ways what has been seen at the whole brain level. We know that there are distinct kinds of learning and memory that depend on distinct brain regions.

对这些问题，我们还不能一一给出答案,不过，迄今为止，通过对小脑的研究，权衡对大脑已知的了解,我们发现，不同的脑区有着各自的学习记忆能力。

So, one difference between photoelectron spectroscopy and, for example, the photoelectric effect is that in this case, we're not just looking at one energy level, which is what we were looking at from the surface of a metal, now we're talking about this gaseous atom.

光电子能谱与光电效应的不同点在于，以这种情况为例，我们不只关心一个能级，就像原来在金属表面那样，现在我们研究的是气体原子，所以，我们可以从原子中。

So what we'll do is this problem here, which is let's calculate out what the wavelength of radiation n would be emitted from a hydrogen atom if we start at the n equals 3 level and we go down to the n equals 2 level.

我们来做这个问题,让我们来计算一下,从n等于3到,等于2能级氢原子辐射的波长是多少。
