The Uncertainty Principle, also known as Heisenberg’s Uncertainty Principle, is a concept in quantum mechanics. Formulated by the German physicist Werner Heisenberg in 1927, it states that there is a limit to the precision with which certain pairs of physical properties, such as position and momentum, can be simultaneously known. In simpler terms, the more accurately we know the position of a particle, the less accurately we can know its momentum, and vice versa. This principle highlights the inherent limitations in measuring quantum systems and is a key feature distinguishing quantum mechanics from classical physics.
