The Heisenberg uncertainty principle states that it's impossible to simultaneously know the position and the momentum of a particle. In other words, if you know exactly where a particle is, you won't know how fast it's going. If you know how fast it's going, you won't be able to tell where it is.
Since the uncertainty principle is such a basic result in quantum mechanics, typical experiments in quantum mechanics routinely observe aspects of it.Certain experiments, however, may deliberately test a particular form of the uncertainty principle as part of their main research program.hus, the uncertainty principle actually states a fundamental property of quantum systems, and is not a statement about the observational success of current technology.
