Due to his insight, we call this unit Planck's constant (h). The word quantum
derives from quantity and refers to a small packet of action or process, the
Planck's constant definition, the fundamental constant of quantum mechanics,
expressing the ratio of the energy of one quantum of radiation to the frequency of
Robert A. Millikan's 1916 paper on the measurement of Planck's constant was
dramatic in its time. Today it lends itself to different, yet complementary, ...
