'The Mechanics of Mechanical Watches and Clocks' presents historical views and mathematical models of mechanical watches and clocks. Although the mechanical clock is over three hundred years old and is still a popular luxury item today, its theory has never been examined in detail as in this book. The illustrations and computer animations are unique and have never been published before. It will be of significant interest to researchers in mechanical engineering, watchmakers and clockmakers, and people with an engineering background who are interested in mechanical watches and clocks. It will also inspire people in other science and technology fields, such as mechanical engineering, electronics engineering, to advance their designs.
