Heisenberg's Uncertainty Principle isn't about the observer effect at all, though: as other answers have explained, this uncertainty in position vs. momentum is a fundamental property of the system irrespective of measurement. The uncertainty exists even without a measurement being performed. Heisenberg's 1925 paper was in fact explicitly demonstrating that it is fundamental rather than an artifact of the observer effect. | |
