(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 ...

In new research, scientists from Aalto University in Finland say they’ve skirted the Heisenberg Uncertainty Principle that underpins—or undermines—every experiment in quantum mechanics.
