As an analogue calculating instrument in combination with mathematical sets and drawing utensils, the sector was a practical companion for architects, engineers and scientists for over two centuries.This book is the first to present outstanding mathematical instruments and sets that show us the beauty and craftsmanship of scientific instruments in their most marvellous form. However, it is not only the unique, fine aesthetics of these instruments that appeal to us, but also their history of development and the mathematical background. The pinnacle of precision instrument making in the early modern period was the versatile sector developed by famous mathematicians such as Galileo Galilei and Jost Bürgi. The cultural-historical significance of these instruments is presented with precious objects from the most important collections of the history of science in Europe, such as the Musée du Louvre in Paris, the Museo Galileo in Florence, the Astronomisch-Physikalisches Kabinett in Kassel, the Arithmeum in Bonn, the École nationale des ponts et chaussées in Paris, the Galerie Delalande, Paris and the Rocca Collection.What better place than the Arithmeum for such an exhibition of the finest preserved maths and arithmetic instruments?
