Revolution in Time: Newtonian Physics and its Influence on John Harrison’s Pendulum Clocks

Wednesday, 5 October 2016

Lecture Theatre, National Maritime Museums, Greenwich

Following the extraordinary trials of Burgess Clock B at the Royal Observatory, the History of Physics group of the Institute of Physics will convene a one-day conference at the National Maritime Museum on Wednesday, 5 October. Papers will explore the influences of Newtonian physics on the fundamental principles of John Harrison’s pendulum clocks. There will be an opportunity to visit the Royal Observatory to see Burgess Clock B alongside John Harrison’s sea clocks and ‘Late Regulator.’

Cost: free for Institute of Physics members; £25 for non-members.
