For instance, placing a particle in a small box lets us know its position fairly precisely, but it leaves the momentum with a wide range of possible values. Another way of looking at this is through measurement effects. Heisenberg himself gave the example of a microscope that scatters photons from a particle to measure its position. The shorter the photon wavelength, the more precise the position measurement can be, but also the greater the disturbance to the particle’s momentum. However, recent work with so-called “weak” measurements seems to indicate that disturbances can be less than Heisenberg would predict.
