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

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 ...

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 ...

Would you believe a pendulum clock that can keep time accurately to within one second per year? If you answered “yes”, you’ve either never tried to regulate a pendulum clock yourself, or you already ...

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 ...

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.

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 ...

John Harrison, one of the world’s greatest clockmakers, claimed to have designed the perfect pendulum clock in the mid-18th century. Instead of being celebrated, Harrison’s plans were chastised and ...

The Pendulum Wall Clock was one of the most common household items in the past. It was made of wood and glass, with a ...

The clocks of the 17th century were not accurate, which was a problem for Dutch physicist, mathematician, and astronomer Christiaan Huygens. His work in astronomy required accurate timekeeping, and ...

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 ...
