For systems with few bodies in motion with one degree of freedom, it is easy enough to use various methods to locate an object ( e.g. ultrasound, interferometery, or even a $t$$x$$P(x) = \sqrt{\dfrac{1}{2\pi\sigma^2}}e^{-x^2/2\sigma^2},$$\sigma^2=\left< x^2\right>=2Dt.$$\mu$$\langle x^2 \rangle$$\…
