IS HEISENBETRG'S UNCERTANITY PRICIPLE APPLICABLE FOR ALL PARTICLES

Heisenberg's uncertainty principle is applicable for microscopic particles .It states that it is impossible to measure simultaneously both the position and velocity (or momentum ) of a microscopic particle with absolute accuracy or certainty .But this cannot be so when the particle is extremely minute,such as an electron  .It will suffer a change in its velocity and position due to the impact of even a single photon of light used to observe it .After the impact of a light photon the position and velocity of the electron may be quite different from the original position and velocity .Thus the uncertainty principle is significant in the case of microscopic particles like electrons .
