Chemical and physicochemical recycling of plastic waste

In the unpublished manuscript Historia et origo calculi differentialis (written toward the end of his life, around 1714–1715), Leibniz clearly establishes the connection between combinatorics and differential calculus. The article aims to highlight how this short treatise, existing in two manuscript versions—a first version, which emphasizes theoretical foundations, and a second version, which responds more directly to accusations of plagiarism—demonstrates the importance of numerical tables and schemes at the origin of finite difference theory in Leibniz’s early Parisian research.
