So, let's say we're talking about the baseball, have a wavelength of the baseball that's on the order of the baseball.
克服质量的效应,比如说以棒球为例,要棒球的波长有它尺寸数量级的波长。
So, in terms of wavelength, Wakefield has the largest wavelength, but in terms of being significant, we're still not even close.
所以,Wakefield投出的球,有最大的波长,但是从可比性来讲,它实际仍未接近球的尺寸。
We know that this dimension is roughly one angstrom unit, right?
我们知道,它的尺寸大概是一埃,对吗?
So this is, first of all, even just on an absolute scale, this is way, way larger than the wavelengths we're talking about for baseball.
首先,即使在一个绝对标度下,棒球的尺寸也,远远地大于它的波长。
The only thing that's different is that they're one down on the periodic table, potassium is down one row, so it's going to be a little bigger, but when we're thinking about size, it maybe does not seem that significant to talk about the size.
它们唯一的不同点,就在于其中一个在周期表的下面,钾在下一行,因此它要稍微大一些,但是当我们考虑尺寸的时候,似乎讨论尺寸的意义不大。
So, then we'll get to turn to a new kind of mechanics or quantum mechanics, which will in fact be able to describe what's happening on this very, very small size scale -- so on the atomic size scale on the order of nanometers or angstroms, very small particles.
然后我们要讲到一种,新的力学--量子力学,它可以解释,发生在很小尺度,大约是原子尺寸大小,也就是纳米或埃的量级。
