JILA researchers are pioneering a nuclear clock using thorium-229, which offers unprecedented stability compared to atomic ...

For decades, atomic clocks have been the pinnacle of precision timekeeping, enabling GPS navigation, cutting-edge physics ...

He suggested that an atom was a tiny solid ball. He published his ideas in 1803. This atomic model has changed over time. Scientists used the model to make predictions. Sometimes the results of ...

This transition is less sensitive to environmental disturbances than modern atomic clocks and has been proposed for tests of fundamental physics beyond the Standard Model. This idea isn't new in ...
