About the Uncertainty Principle
The Heisenberg Uncertainty Principle states that certain pairs of physical properties (conjugate variables) cannot both be known to arbitrary precision. For position and momentum: ΔxΔp ≥ ℏ/2. For energy and time: ΔEΔt ≥ ℏ/2. This is a fundamental property of quantum systems, not a limitation of measurement technology.
