Max Karl Ernst Ludwig Planck, FRS[2] (/plÉËÅk/;[3] 23 April 1858 â 4 October 1947) was a German theoretical physicist whose discovery of energy quanta won him the Nobel Prize in Physics in 1918.[4]
The Planck constant is named after Max Planck, the instigator of quantum theory, who discovered it in 1900. Classical statistical mechanics requires the existence of h (but does not define its value). Planck discovered that physical action could not take on an arbitrary value.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.
