Book Description
A General History of Horology describes instruments used for the finding and measurement of time from Antiquity to the 21st century. In geographical scope it ranges from East Asia to the Americas. The instruments described are set in their technical and social contexts, and there is also discussion of the literature, the historiography and the collecting of the subject. The book features the use of case studies to represent larger topics that cannot be completely covered in a single book. The international body of authors have endeavoured to offer a fully world-wide survey accessible to students, historians, collectors, and the general reader, based on a firm understanding of the technical basis of the subject. At the same time as the work offers a synthesis of current knowledge of the subject, it also incorporates the results of some fundamamental, new and original research.

Book Description
An electrical shock, as the name implies, involves the use of electricity in some fashion, but in what manner? An electrical motor connected to the power lines, perhaps? How about an electromagnet reacting with a permanent magnet to utilize the forces of attraction and repulsion to provide the driving force? And what of the use of a solenoid or electromagnet to lift a weight or to wind a spring? All of these are, unquestionably, descriptions of the uses of electricity to provide motive power for clock operation. A need then exists, to eliminate confusion and further define the function of electricity as applied to clocks. The objectives of this publication are to offer an overview of the early research and developments which formed the foundation for practical electrical horology. Also included is a section covering technical information and repair with an emphasis on early battery operated clocks. The final segment contains needed references and a bibliography for sources of additional detail.
