Heisenberg's uncertainty principle tells us that it is impossible to simultaneously measure the position and momentum of a particle with infinite precision. In our everyday lives we virtually ...

Whether you’re laughing right now—or staring at your screen in confusion—hinges on how much you know about one of the foundational ideas in quantum physics: Heisenberg’s uncertainty principle.

Discover how Heisenberg's Uncertainty Principle fits into the larger puzzle of the universe and why it’s essential for a Theory of Everything. More for You.

Devised by the German physicist Werner Heisenberg in 1927, the so-called uncertainty principle states that we cannot accurately know both the position and speed of a particle, such as a photon or ...
