In the fall of 1735, Voltaire was visited by Francesco Algarotti, who was preparing a book about Newton in Italian. Partly inspired by the visit, the Marquise translated Newton's Latin Principia into French, which remained the definitive French version into the 21st century.

While Voltaire remained a firm Newtonian, the Marquise adopted certain aspects of Leibniz's critiques. Voltaire's own book Elements of the Philosophy of Newton made the great scientist accessible to a far greater public, and the Marquise wrote a celebratory review in the . Voltaire's work was instrumental in bringing about general acceptance of Newton's optical and gravitational theories in France, in contrast to the theories of Descartes.
