  • 1916: Physicist, mathematician, and historian Pierre Duhem dies. He wrote: "A theory of physics is not an explanation. It is a system of mathematical propositions, deduced from a small number of principles, which have for their aim to represent as simply, as completely and as exactly as possible, a group of experimental laws."
