The Heisenberg uncertainty principle is a fundamental concept in quantum mechanics, named after the physicist Werner Heisenberg. It states that it is impossible to simultaneously know both the exact position and the exact momentum of a particle with absolute certainty. In other words, the more precisely one property (such as position) is measured, the less precisely the other property (such as momentum) can be known.

Mathematically, the principle is often expressed as Δx * Δp ≥ ħ/2, where Δx represents the uncertainty in position, Δp represents the uncertainty in momentum, and ħ is the reduced Planck constant. This principle has profound implications in the microscopic world and has fundamentally shaped our understanding of quantum mechanics.
