Camus main work. He joined Maupertouis, Clairaut and Lemonnier on the scientific expedition to Lapland in 1736, to determine the shape of the earth. ""In 1730 he was named to the Academy of Architecture and became its secretary shortly thereafter. There he gave public lessons to aspiring architects as the Academy's professor of Geometry. These lessons later served as the basis of a ""Course de mathematique""....In 1755, when Camus was also named the examiner for artillery schools, this ""Course"" became the standard work for artillery students.""
