Ted: Ted Ed: What Is the Heisenberg Uncertainty Principle?
The Heisenberg Uncertainty Principle states that you can never simultaneously know the exact position and the exact speed of an object. Why not? Because everything in the universe behaves like both a particle and a wave at the same time....
