Clocks and the Evolution of Timekeeping – The historical interaction of human social development and timekeeping capability is routinely examined, and never understated. At its fundamental, the drive for improved commerce, trade, national security, and human transportation is supported by the evolution of clock technology. This talk will span across the centuries of scientific discovery and engineering innovation in precision timekeeping devices, moving from the pendulum to GPS satellite atomic clocks, to give a moving perspective on the interdependence for improved timekeeping and technological advancement. An emphasis on the impact to navigation will be maintained  throughout the talk.
