In 1900, when he was merely 4 years old, the German physicist Max Planck formulated an energy theory, postulating the existence of "quanta," which lays the groundwork for the quantum theory of modern physics. In December, he introduced a paper on the Planck postulate which stated that E=hv - the energy of a photon is proportional to its frequency times a constant. Planck won a Nobel Prize in 1918 for his work in theoretical Physics.
