Planck's revolutionary discovery, one of the most influential in all of science, was that energy emitted by a resonator could on have discrete values or quanta.  The energy for a resonator of frequency '''''v''''' is '''''hv''''', where "'''''h'''''" is a universal constant that is now called Planck's constant.  This theory explained discrepancies between theory and observations, and became known as quantum theory.  This helped lay a foundation for the future discovery of quantum mechanics.
