It was exactly one hundred years ago on 14 December 1900 that the great physicist Max Planck (1858–1947) presented to the German Physical Society his revolutionary concept of the quantum of action, using which he successfully explained the spectrum of radiation emitted by a black body. Planck was aided in this momentous discovery by, first, his insistence on empirical veracity and second, the laws of thermodynamics. This history is narrated in several places1, I shall just briefly recall the main features.
