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 ...

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 ...

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 ...

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 ...

In a grandfather clock, a pendulum swings back and forth and this periodic motion is maintained using the energy stored in its suspended weights. This is done with the help of the escapement mechanism ...
