[Stephen Hobley] has been experimenting with an electromagnetic pendulum in order to build himself a clock. Through the course of his experiments, he has learned quite a bit about how pendulums ...

The trick behind the most accurate pendulum clock is that it actually has two pendulums (pendula?). One, enclosed in a metal cylinder held at a decent vacuum, keeps time but doesn’t do any ...

Determining the passage of time in our world of ticking clocks and oscillating pendulums is a simple case of counting the seconds between 'then' and 'now'. Down at the quantum scale of buzzing ...

The "pendulums" which regulate them are the vibrating parts of atoms or molecules. So steady are these oscillations that atomic clocks keep better time than the spinning earth itself ...

This year, Katori has been awarded the 43rd Honda Prize. Atomic clocks use the oscillations of atoms as timekeeping ‘pendulums’ – which, like grandfather clocks, involve weights suspended ...
