Engineering interests and inventions of Isaac Newton

The paper presents engineering interests of Isaac Newton, including some of his technical inventions. So far, this topic has not been studied in a broader manner and in more depth. This article discusses Newton’s youthful passions against the backdrop of the so-called mathematical magic literature. His two inventions, i.e. variants of the reflecting telescope and the marine octant are also discussed. Finally, an example is provided of the involvement of the author of Principia in a discussion around the steam engine and the ship powered by such engine designed by Denis Papin.
