H EISENBERG S UNCERTAINTY PRINCIPLE : In 1927, Werner Heisenberg established that it is impossible to measure, with arbitrary precision, both the position and the momentum of an object imprecision of position imprecision of momentum You cannot measure/observe something without changing that which you are observing/measuring.
