"It is impossible to make a clear cut between science, religion, and art. The whole is never equal simply to the sum of its various parts." -- Max Planck

In his Scientific Autobiography, Max Planck penned a now familiar adage known as Planck's Principle: "A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it."
Ironically, Planck himself is considered an exception to this "rule." At the age of forty-two, in order to propose what would turn out to be a revolutionary quantum explanation of radiation, Planck had to reconcile himself with Boltzmann's statistical interpretation of entropy--a theory Planck had resisted for over twenty years.
