We have been measuring time for millennia. Prof. Roee Ozeri, Department of Physics of Complex Systems and Institute Vice President, provides an engaging history of these efforts, their inspiration, and their efficacy, from the sundial to the pendulum to modern atomic clocks.
Prof. Ozeri explains why it is vital to have very precise clocks: they are key to GPS, deep space navigation, high-speed communication networks, cyber security and banking, and science – the accuracy of a lab is limited by the precision of its clock. Today, optical atomic clocks are supporting the search for dark matter.
