if we can't think what system it belongs to, that's tantamount to saying we really don't know what it is.

我们就不知道它从属于哪个符号系统，我们就不能认识它了。

Now remember, we went through before how it's a state function but to calculate it, you'd need to find a reversible path, along which you can figure this out.

请记住，我们不需要知道它是怎样的一个态函数,只计算就可以了，你需要找到一条可逆路径，沿着这条路径就能算得这个结果。

If we had perfect financial markets-- and this is intuitive-- and I don't know how obvious this is, it's obvious to me, but it's an intuitive point of great importance-- nobody would suffer alone.

We know there is no thing called a massless rope, but most ropes have a mass, but maybe negligible compared to the two blocks you are pulling, so we'll take the idealized limit where the mass of the rope is 0.

我们都知道无质量的绳子是不存在的,是绳子就有质量,但是相比于这两个物体就可以忽略不计了,所以我们有了这个理想的条件,即绳子的质量都是 0

So, that is a tricky problem to begin with because if you take this formula here, it tells you y if you know t, but no, we're not saying that.

以这个问题刚开始的时候有点难度,因为如果你要用这个公式,求y的时候就一定要知道t,但是,我们不知道
