The invention of the quantum energy concept according to Planck
arXiv:physics/0106037
Abstract
A hundred years ago, the quantum concept provoked a revolution in science and the search of a new conceptual basis for whole physics, as emphasized by Einstein. In this paper, I discuss the essential features of Planck's works in 1900 on the blackbody radiation and the hypothesis of energy quantization.
