In quantum terms, you can blame Heisenberg's uncertainty principle, which says the more precisely we know a particle's speed, the less we know about its position, and vice versa.

用量子力学的术语来说，这可以归犯罪于海森堡不确定原理，这个理论认为如果我们所知道的粒子的速率愈为精确，那么对于它所处的位置就只能知道得愈不精确，反之亦然。

A 100% uncertainty in the position 15% gives rise to a 15% uncertainty in velocity.

从完全不确定的位置,到速度的不确定度为。

And since we are not expecting the mass of the particle to change, what we really are saying is the uncertainty in its velocity times the uncertainty in its position is greater than the ratio of the Planck constant divided by 2 pi.

因为我们不期望,粒子质量发生变化，我们说的是,它速度的不确定度,乘以它位置的不确定度,比普朗克常量,除以2除以圆周率要大。

And to just give you a sense of what this is, the analytical expression that Heisenberg gave in one of its forms is that the uncertainty in the momentum a particle times the uncertainty in its position, this is the uncertainty.

给你说明一下什么是，分析的表述方式,海森堡给出的按照它的其中一种形式,那就是,粒子动量的不确定度乘以,位置的不确定度，这是不确定关系。
