And what he said was that when you get down to atomic length scales there are limits, there are constraints on our ability to observe.

讲的就是,当你去进入到原子长度的尺度中,我们的观察能力,有一定的限制条件。

But notice, even if there is incredible constraints on grammars, still--we could still produce an infinite number of sentences.

但是请注意,即使语法有着难以置信的不足,我们却依然可以创造出无限数量的句子

It expands. You change your constraints on your system, you heat it up some more, then you take the heat source away, and you put it back in contact with the atmosphere. And you cool it a little bit, change the constraints, cool it a little bit more, and heat, and you've got a closed cycle engine.

让它与大气接触冷却,改变约束，使它继续冷却，然后又再次加热,这就是循环热机，我们以前也研究过，更复杂的机器。

And the mathematics of that equation involved a double derivative in time of x 0 plus some constant times x equals zero with some constraints on it.

那个数学方程式,包括了x对时间的二阶导数,加上常数乘以x等于,还有一些限制条件。

This is the remarkable thing about so many of Milton's similes: they're always bursting out of whatever critical or theological constraints that we work so hard to impose on them.

这是弥尔顿的比喻中的亮点：,它们总是能从我们强加的,无论多批判多神学的束缚中,挣脱出来。

Now this is--;So, these are constraints on grammar and they're really interesting because they tell us what's a humanly natural language versus what's not a humanly natural language.

这些就是语法的不足,它们很有意思,因为它们可以告诉我们,什么是人类的自然语言,什么不是人类的自然语言

For a real gas it depends on more than the temperature STUDENT: Are there any other constraints similar to that .

而对实际气体，这是不对的,它的内能不仅仅依赖于温度,学生：有其他,类似的约束吗？

STUDENT: Just a quick question on some of the constraints, like isothermal, isobaric, isovolumetric expansion.

学生：我有个关于,等温，等压，等容等约束条件的小问题。
