**Question: State and explain heisenberg uncertainty principle?**

The Heisenberg uncertainty principle, formulated by physicist Werner Heisenberg in 1927, is a fundamental principle of quantum mechanics. It states that there is a fundamental limit to the precision with which certain pairs of physical properties of a particle, such as position and momentum, can be known simultaneously.

The uncertainty principle arises from the wave-particle duality of quantum objects. It states that the more precisely we try to measure the position of a particle, the less precisely we can know its momentum, and vice versa. This means that there is inherent uncertainty in the simultaneous measurement of these complementary properties.

Mathematically, the uncertainty principle is expressed as Î”x * Î”p ≥ h/4Ï€, where Î”x represents the uncertainty in position, Î”p represents the uncertainty in momentum, and h is the Planck constant.

The Heisenberg uncertainty principle has profound implications in quantum mechanics. It challenges the classical notion of determinism, stating that it is impossible to know the exact values of certain pairs of properties simultaneously. It places fundamental limits on our ability to observe and measure the behavior of quantum particles, highlighting the inherent probabilistic nature of quantum physics.
