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 ...

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 ...

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 ...

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 ...

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 ...

In 1665 Christiaan Huygens discovered that two pendulum clocks, hung from the same wooden structure, will always oscillate in synchronicity. Today, some 350 years on, Eindhoven and Mexican researchers ...

Talk about your mixed timekeeping metaphors: there are clocks, and pendulum clocks, and there are Nixie clocks, and persistence of vision clocks. But this is a Nixie pendulum POV clock, and we think ...

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

Pair of physicists bust a 350-year-old conundrum in a report that proposes a transfer of energy through a sound pulse causes clocks to synchronise Almost 350 years ago, Dutch inventor and scientist ...

The 350-year-old mystery of why pendulum clocks hanging from the same wall can influence each other and synchronize over time may hold even more secrets than previously thought, researchers say.

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 ...
