Pendulum clocks aren’t used quite as often these days as their cumbersome mechanics and timekeeping abilities have long been outshone by electronic alternatives. However, they’re still fun and they do ...

In a grandfather clock, a pendulum swings back and forth and this periodic motion is maintained using the energy stored in ...

[Vinnie] has a wonderful old clock from his grandmother; it’s an exquisite antique with a real mechanical movement and a charming set of bells that ring every hour. Unfortunately, those chimes are a ...

Researchers have designed a quantum version of a pendulum clock. It could shed light on timekeeping in the quantum realm ...

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 ...

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 ...

A supersolid is a paradoxical state of matter—it is rigid like a crystal but flows without friction like a superfluid. This exotic form of quantum matter has only recently been realized in dipolar ...

You have heard of Christiaan Huygens, haven’t you? A Dutch astronomer, inventor, physicist and mathematician, Huygens is often considered to be among the best scientific minds to have ever roamed the ...

Comtoise watches, as seen here in the Comtoise Museum of master watchmaker Bernd Deckert, are a French pendulum clock from the French region of Franch-Comte. While they are beautiful antiques, they ...

As a rule, Donald Saff doesn’t collect clocks he can’t see inside of. It’s the harmonic entanglement of gears—and the skill needed to craft them—that first lured him to horology, the study of ...

For millennia, humanity's one-and-only reliable way to keep time was based on the Sun. Over the course of a year, the Sun, at any location on Earth, would follow a predictable pattern and path through ...

Scientists may have finally discovered why pendulum clocks synchronise when placed nearby. After 350 years two Portuguese researchers believe that pendulum clocks eventually swing together because of ...
