How Next generation Atomic clocks are redefining the 'second'
Показать описание
Measuring time accurately is a very important task. Be it personal life or something like dark matter research, time measurement is a must. In this video I will discuss how atomic timekeeping is done and how the researchers around the globe are trying to modify the atomic clocks. Also by modifying the existing microwave based clocks to optical clocks, the global definition of 1 second is going to change.
