Why not spend one of the people together and is willing to bump their heads against a wall?

为什么会为一个不能相守在一起的人而愿意为此碰得头破血流？

This is all very well, but the physicist comes along and shows that you never bump into anything: even when you run your head against a stone wall, you do not really touch it.

这当然不错。不过，一个物理学家会过来，他会向你展示，你永远也不会碰撞上任何东西，即使你用你的脑袋猛地撞上了一道石墙，你也不会真正地碰上它！

We can work when they finally find a bump their heads against a wall hungry people in the work done;

我们可以工作的时候，撞得头破血流才勉强找份饿不死人的工作做；

It will scare you to death, not of things that go bump in the night but of the upstanding citizen next door who stands ready to bump you up against the wall at the drop of a hat.
