The Heisenberg Uncertainty Principle is a fundamental concept in quantum mechanics that states it is impossible to simultaneously know both the exact position and exact momentum of a particle. This principle highlights the inherent limitations in measuring quantum systems, suggesting that the more precisely one property is measured, the less precisely the other can be known. This principle was formulated by physicist Werner Heisenberg in 1927 and has profound implications for our understanding of the quantum world. It challenges classical notions of determinism and introduces a level of fundamental uncertainty in the behavior of particles at the quantum level.
