Maybe you guys know.

可能你们知道
You know what else it can do

你们知道如果它从这里开始运动
if it starts here? Yes?

会发生什么事情请回答
It can suddenly find itself here

它可能会突然发现自己在这里
and that's not allowed by classical mechanics

这对于经典力学是不可能发生的
because to do that it has to go over the hump.

因为要做到这样必须爬过这个峰
Look what's happening at the hump.

在峰值处会怎样
I've got more kinetic energy than I have total energy.

我的动能会比总能量更多
I'm sorry, I've got more potential energy than I have total energy.

不好意思我的势能会比总能量更多
That means kinetic energy is negative,

这就意味着动能是负值
that's not possible,

这是不可能的
because 1 / 2·m·v^2 can never be negative.

因为 1 / 2·m·v^2 不可能是负值
