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.
The uncertainty principle played an important role in many discussions on the philosophical implications of quantum mechanics, in particular in discussions on the consistency of the so-called Copenhagen interpretation, the interpretation endorsed by the founding fathers Heisenberg and Bohr.nd similarly, this situation should not, by itself, cast doubt on the question whether Heisenberg's relation can be regarded as a principle of quantum mechanics. There is a second notable difference between (2) and (9). Heisenberg did not give a general definition for the âuncertaintiesâ Î´ p and Î´ q.
