Physics World, "Max Planck: the reluctant revolutionary", 01 Dec 2000. Quote: "According to Boltzmann's molecular-mechanical interpretation, the entropy of a system is the collective result of molecular motions. The second law is valid only in a statistical sense. Boltzmann's theory, which presupposed the existence of atoms and molecules, was challenged by Wilhelm Ostwald and other "energeticists", who wanted to free physics from the notion of atoms and base it on energy and related quantities. What was Planck's position in this debate? One might expect that he sided with the winners, or those who soon turned out to be the winners – namely Boltzmann and the "atomists". But this was not the case. Planck's belief in the absolute validity of the second law made him not only reject Boltzmann's statistical version of thermodynamics but also doubt the atomic hypothesis on which it rested." https://physicsworld.com/a/max-planck-the-reluctant-revolutionary/
