(Heisenberg called this matrix mechanics, soon shown to be equivalent to Erwin Schrödinger's more visualizable wave theory.) The uncertainty principle was hard even for scientists to accept at first.

The Heisenberg uncertainty principle says that we cannot know both the position and the momentum of a particle at once Imagine driving a car fitted with a GPS navigation system that glitches ...

Werner Heisenberg's high school ... He tied this up in an equation using Planck's constant, and called it the uncertainty principle. While many resisted this idea, it eventually became accepted ...

Utilizing Ramsey interferometry, the researchers confirmed that the phase measurement sensitivity approached the Heisenberg limit. This long-lived Schrödinger-cat state paves a new way for atomic ...
