In classical physics, knowing an object's position and speed allows us to predict its exact path. In the quantum realm, however, nature imposes a fundamental limit on certainty.

Formulated by Werner Heisenberg in 1927, the Uncertainty Principle states that the more precisely you measure a subatomic particle's position (Δx), the less precisely you can know its momentum (Δp), and vice versa:

Rather than a flaw in our measurement tools, this uncertainty is an intrinsic wave-particle property of matter. Watch the video above to explore why "the more you know, the less you know" underpins the fundamental behavior of the quantum universe.
