It only applies to something as small as an electron or a system in which the amount of energy required to observe the system or particle (laser measuring device, etc.) is significant comparerd to the amount of energy present in a system. The lower the power of the measuring device, the more approximate the measurement is. The higher the power of the measuring device, the more it wll affect the particle being measured.
