So, we need a new kind of mechanics, which is quantum mechanics, which will accurately explain the behavior of molecules on this small scale.
所以我们需要一种新的力学，也就是量子力学，来解释在这个，小尺度下分子的行为。

We can't cope with the very tiny scale of quantum physics or the very large scale of relativity.
对于量子物理中的微观尺度或相对论中的宏观尺度，我们都无能为力。

Because this was done at such a small scale, the way the atoms interact can produce new and different properties according to the rules of quantum physics.
