Sonar to Quartz Clock examines how the unapplied phenomenon of piezoelectricity became applied for technologies such as sonar, crystal frequency control, the quartz clock, and how its research has consequently changed during WWI and the interwar period. It aims at reconstructing, for the first time, the fascinating history of the inventions and the development of these highly important technologies, which are still in extensive use, and which were crucialfor the electronic revolution, arguably the most important technological developments of the twentieth century.On this basis, this book suggests a better and more nuanced understanding of the relationships between modern science and technology and the process of development and innovation of science-based technologies. It examines in particular the mutual transfer and transformation of knowledge between them including the way physics becomes practically applicable, the way applications and societal interests shape technology and scienc
