What connects quantum mechanics and relativity? Discover how Heisenberg's Uncertainty Principle fits into the larger puzzle of the universe and why it’s essential for a Theory of Everything.

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.

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 ...

The Heisenberg uncertainty principle, which has origins in physics, "states that there is a limit to the precision with which certain pairs of physical properties of a particle, such as position ...
