That big grandfather clock in the library might be an impressive piece of mechanical ingenuity, and an even better example of fine cabinetry, but we’d expect that the accuracy of a pendulum timepiece ...

Using this design, you can construct an electromagnetically impulsed pendulum clock with a 1-second beat. On the prototype, the pendulum rod is 115cm long with a bob adjusted to make it beat every ...

A new project has been published to the Hackster.io website this week from Jeremy Cook, who has created a unique single nixie pendulum POV clock powered by an Arduino Nano microcontroller together ...

By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in ...
