我们可以从物理的层面来解释。

We can explain it in physical terms.

这里给你举个物理的例子。

Well, one example is actually in physics.

有时，物理的移动数据仍然是更好的方式。

Sometimes, it's still better to physically move data.

That means that this temperature right here is the absolute lowest temperature you can go to that physically makes any sense.

是物理上不可能的状态,也就是说这一点,对应的温度是物理上。

And it follows qualitatively from just your ordinary observations a bout the direction in which things go spontaneously, right.

定性地来说,就是你们日常生活中观察到,自发进行的物理现象,会有方向性。

And so this is not like a math problem set or a physics problem set. Or, like a high school physics lab, where we all know what the answer should be, and you could fake your lab results anyway.

或是物理问题集合,又或者是高中的物理实验室，我们对这些问题都有确切的答案，或者你可以把你的实验结果改成正确的，有些事情是不能明确界定的。
