Why Do We Even Need A Clock This Accurate?

50x50: Science Across America is a national series uncovering exceptional science in all 50 states. It is a production of the Independent Media Initiative in collaboration with HHMI Tangled Bank Studios, Alfred P. Sloan Foundation, and the Winn Family Foundation. See all the states at https://5050science.com In 1656, Christiaan Huygens invented a pendulum clock that, based on the period of its pendulum swings, could measure time down to the second. Today, we have clocks that measure a second out to 19 decimal places. What’s the point of subdividing time into such infinitesimally tiny fractions?
