Your Definition
Verb that expresses the concept that the act of [talking] about a phenomenon changes the phenomenon. For example, if you see a squirrel come within 5 [feet] of where you are sitting, and you attempt to alert your companions, the act of alerting them [will] scare off the squirrel. Taken from Heisenberg'[s] Uncertainty Principle, which holds that it is not possible to know with certainty both the position and the momentum of a particle. The act of measuring either variable changes the other.
