The Uncertainty Principle Demystified.

Werner Heisenberg's uncertainty principle states that we cannot know both the position and speed of a particle, such as a photon or electron, with perfect accuracy and that the more we nail down the particle's position, the less we know about its speed and vice versa. In less elaborate wording. There is only one principal whose principle reason is not to be alone.
