The Heinsenbergâ€™s Uncertainty principle was proposed by a German theoretical physicist Werner Heisenberg in 1927. It dictated that at miniscule level of quantum mechanics, it becomes impossible to measure a particleâ€™s exact location with any degree of precision. You canâ€™t measure the articleâ€™s position without affecting it momentum in an unpredictable way. Uncertainty is inherent in the quantum realm.

The uncertainty principle can be a variety of mathematical inequalities asserting a fundamental limit to the precision with which certain pairs of physical properties of an article known as complementary variables. For example, the more precisely the position of some particles is determined, the less precisely its momentum can be known and vice versa.

In the past the uncertainty principle has been confused with the observer effect. The observer effect notes the measurements of certain systems cannot be made without affecting the systems. Heisenberg explained the observer effect at the quantum level as a physical explanation of quantum uncertainty.

The uncertainty principle is a basic result in quantum mechanics. Typically experiments in quantum mechanics observer aspects of it. Some experiments may deliberately test a particular for of the uncertainty principle as part of their main research program.
