我不知道老师在说什么，我也不知道如何做家庭作业。

I don't know what the teacher is saying and I don't know how to do homework, either.

首先，情形一，你们知道如何做。

First of all, situation number one, well, you know how to do that.

我不敢说自己知道如何做。

I make no claims to know how to do that.

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。

What have we done over the last three or four lectures? We've started introducing you to classes of algorithms. Things that I'd like you to be able to see are how to do some simple complexity analysis.

我们在过去三节或四节课中讲了什么？,我开始向你们,介绍算法的类型,我想你们知道的是,如何做一些简单的复杂度分析。

So now that we can do this, we can compare and think about, we know how to consider wave functions for individual electrons in multi-electron atoms using those Hartree orbitals or the one electron wave approximations.

现在我们可以做这些了，我们可以对比和考虑，我们知道如何用哈特里轨道,或者单电子波近似去考虑,多电子原子中的单个电子波函数,所以对于我们研究了。
