Pendulum clocks swinging in exactly the opposite direction from each other. The 350-year-old mystery of why pendulum clocks hanging from the same wall synchronize over time may finally be solved, ...

Christiaan Huygens was a busy scholar. Among his many achievements, the Dutch scientist figured out the shape of Saturn's rings and discovered that planet's largest moon, Titan. He founded the theory ...

Discover how reading a quantum clock can surprisingly cost more energy than keeping it ticking, impacting timekeeping and ...

Hang two pendulum clocks on the same wall, and over time, something strange will happen: the two clocks will tick in synchrony. Renowned Dutch scientist Christiaan Huygens, the inventor of the ...

What a makes a good clock? Andrew Ludlow, a physicist at the National Institute of Standards and Technology, says one of the most important criteria is stability. "If you could imagine a grandfather ...

Three years ago, I published a blog post saying, “Today, there are calls for keeping Daylight Saving Time throughout the year.” Much of that opinion came from worries that tinkering with time has ...

Here’s how to build a pendulum-controlled clock which can be made really accurate. Retro? – yes, but an interesting project all the same. You’ll need a spare quartz clock which must be adapted by ...

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 ...
