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.
There are several related constants for which more that 99% of the uncertainty in the 2014 CODATA values is due to the uncertainty in the value of the Planck constant, as indicated by the square of the correlation coefficient ().n principle, the Planck constant could be determined by examining the spectrum of a black-body radiator or the kinetic energy of photoelectrons, and this is how its value was first calculated in the early twentieth century.
