The Heisenberg Uncertainty Principle
... Principle The Heisenberg uncertainty principle states that it is impossible to know both the momentum and the position of a particle at the same time. This limitation is critical when dealing with small particles such as electrons. But it does not matter for ordinary-sized objects such as cars o ...
