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

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. After decades of experiments with the ...

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 ...
