"As certain as she is sometimes and as absolutely gung-ho and young and courageous and brave, she is also willing to take a step back and go 'okay,I'm going to reconsider my options and how I'm treating everybody' because she acknowledges that she's being a little bit selfish.

So, that's probability density, but in terms of thinking about it in terms of actual solutions to the wave function, let's take a little bit of a step back here.

这就是概率密度，但作为,把它当成是，波函数的解，让我们先倒回来一点。

So, we'll take a little bit of a step back after we introduce quantum mechanics, and talk about light as a wave, and the characteristic of waves, and then light as a particle. And one example of this is in the photoelectric effect.

等我们介绍完量子力学后,我们要回过头来讨论下光,作为一种波和它的波动性特征,以及光作为一种粒子,其中的一个粒子就是光电效应。

Take a step way back and think about what's the basic mechanism by which cells receive signals.

现在让我们回过头来思考,细胞接收信号的基本原理

So, one thing we said last time was when we put up a model and try and draw lessons from it, we should just take a step back and say, what's missing here?

在上一讲,当我们,从一个模型中总结结论的时候,我们应该回过头重新审视一下,看看我们是不是疏漏了什么

On the next step though, this, we get substituted by that. Right, on the next step, I'm back in the even case, it's going to take six more steps, plus t of b minus 1. Oops, sorry about that, over 2.

这一步就是偶数了，这一步会让我们得到，6+t这样的结果，因为b-1现在是偶数了,别忽略这里的细节。

So, what we say here is we need to take a step back here and come up with an approximation that's going to allow us to think about using the Schrodinger equation when we're not just talking about hydrogen or one electron, but when we have these multi-electron atoms.

所有我们这里要说的是,我们需要退回一步,做一个近似,那样可以使我们用,薛定谔方程来考虑,让我们不是仅仅在讨论氢原子或者,一个电子的时候，而是多个电子的原子。

Let's take a step back and ask are all kinds of cells really the same and start by talking about two cells that I know you know are quite different.

让我们退一步并问一句,所有细胞真的都是一样的么,我们不妨从两种,看起来截然不同的细胞谈起

Well let's take a step back for a minute; that's one way of looking at Biomedical Engineering, by looking at sort of the things that you know about that have been the result of the work of biomedical engineers and talk more generally.

好的,话说回来,了解生物医学工程的一种方法就是,通过看一些你们熟悉的东西,它们同时也是,生物医学工程的研究成果,并对它们做一般意义上的讲解
