If you took a 15 inch artillery shell moving at the velocity it typically goes at, and take that amount of kinetic energy versus the resistive capacity of a sheet of tissue paper, that's the scale that we're looking at here.

如果你有1个15英寸的炮弹,按照经典的速度移动，会消耗大量的动能,抵抗来自于一张薄纸的阻力，这就是我们在这儿看到的尺度。

And he gave a very good analogy in saying, "It was almost as incredible as if you'd fired a 15 inch shell at a piece of tissue paper, and it came back and hit you."

他还打过一个很好的比方：,“这就像是,你用个15英寸果壳,打到面巾纸上被弹回来打到你，一样不可思议，“

They are a function of the instant atomic arrangement, how we arrange the atoms: same composition, simple example, one inch thick pine board, one inch thick plywood.

那是即时的原子排序,的功能，我们如何排序原子，同样的成分，简单的例子，一英寸厚的松木板，一英寸厚的胶合板。
