Before there were Ipods, GPS, television, moon exploration and space travel, and all manner of scientific instruments, there was a universal quest for measuring time. James Moss will explain many of the methods and technology leaps in the last 700 years to track time, from the simple shadow passing a line in the sand to quantum physics. Each gain in precision came with new challenges and required advances in technology to overcome. Lest you think we know all there is to know about time keeping today, rest assured that time keeping research is on-going. James Moss is a Professional Associate (Semi-Retired) of the American Institute for the Conservation of Historic and Artistic works (AIC). He has been in full time private practice as a horological restorer since 1969 and as a Conservator since 1993. He was a Director of the New England Conservators Association, and a co-founder of the National Association of Watch and Clock Collectors Chapter 87. He lectured for many years on the technical aspects of clock repair and restoration for several NAWCC Chapters, and has designed and built over 30 sundials. James holds an ASEE from Wentworth Institute and served as a consultant to Arthur D. Little Corp on micro-mechanical mechanisms. He published a paper on the relationship of ammoniated clock cleaning solutions currently being used by the horological community and the potential for developing Stress Corrosion Cracking of the brass components.
