The physics of timekeeping: from Stonehenge to atomic clocks - Livestream

The need to tell the time connects you to over five thousand years of human history. From the first solstice markers at Newgrange to quartz crystal oscillating in your watch today.

Join Chad Orzel as he discusses time from orbital motion and axial tilt to the quantum mechanics and relativity theory that gives us our ultra-precise atomic clocks.

In this talk, Chad explores the wondrous physics that makes time something we can set, measure and know.
