That big grandfather clock in the library might be an impressive piece of mechanical ingenuity, and an even better example of fine cabinetry, but we’d expect that the accuracy of a pendulum timepiece ...

Projects can often spiral, not down or up, but out. For [Derek] he started playing around with a 3D printed escapement mechanism and thought it was a wonderful bit of engineering. But with a simple ...

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 ...

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 ...

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 ...
