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.
因爲我們不期望,粒子質量發生變化，我們說的是,它速度的不確定度,乘以它位置的不確定度,比普朗尅常量,除以2除以圓周率要大。

For such a particle, it is possible to work out its velocity (from the time taken to pass between the two layers) and its trajectory (from the relative positions of the elements triggered in each sensor layer).

In this case, the signal is a particle's momentum—that is its mass times its velocity.
