 The Physica Electiva is Sturm’s masterpiece. It is divided into three parts: a physica generalis (general physics) that lays down the foundations of Sturm’s system and includes his discussion of key metaphysical themes such as the nature of matter, form, and causation; a physica specialis (special physics) that covers the main phenomena of the supralunary and the sublunary world; and a physica specialissima (very special physics) that is devoted to the study of life and human beings. During his life, Sturm managed to published only the physica generalis. The physica specialis was published posthumously by Christian Wolff in 1722. The third part has never been published. It has been alleged that it were held in manuscript form by the city library of Nuremberg (Gaab, in Gaab et al. 2004). Based on archival research conducted by one of the authors (C. Henkel) in the city library of Nuremberg in October 2019, he thinks no such manuscript exists there. However, the city library of Nuremberg holds what he takes to be study notes of Sturm’s students on courses in natural   philosophy.[1]
