Lecture: Hairspring Dynamics

This is the original lecture given by Dr. Matthew Clark on the topic of Hairspring Dynamics for American Watchmakers-Clockmakers Institute (AWCI).

From the video description:

“Dr. Matthew Clark makes an analysis of hairspring behaviors such as isochronism, positional effects, and poising using modern mathematical techniques. Some of the truisms of the watchmaking craft are confirmed, others challenged through dynamic simulations of the balance wheel and hairspring. This work uses computer analysis to update the work done by Grossman, Lossier, Phillips, and Airy in the early 1900’s. This is a recording of a workshop given before a live audience. It is uncut and unedited and no assurances are made with regard to its video or audio quality.”

Dr. Matthew Clark holds a PhD in physical chemistry. At the time of this lecture, he worked for the Institute for Scientific Information.
