Historians have different views on the core identity of analogue computing. Some portray the technology solely as a precursor to digital computing, whereas others stress that analogue applications existed well after 1940. Even within contemporary sources, there is a spectrum of understanding around what constitutes analogue computing. To understand the relationship between analogue and digital computing, and what this means for users today, the history must consider how the technology is used.
This book investigates the technologies, the concepts, and the applications of analog computing. The book suggests a new interpretation of the history of analog computing, and argues that analog computing can be thought of as a modeling technology.
