When you think of making something using a lathe, you usually think of turning a screw, a table leg, or a toothpick. [Uri Tuchman] had a different idea. He wanted to make a clock out of the gears used ...

Nuclear clocks are a technology researchers have been working toward for decades. New research in theoretical physics brings them closer to reality.

We love a good clock project, and [byeh_ in] has one with a design concept we don’t believe we have seen before. The Trace ...

The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these measurements far more accurate. In 2003, engineers from Germany and ...

There is a good reason why the Doomsday Clock stands at 90 seconds to midnight. Over the recent years, the hands of the Clock dutifully registered the steady deterioration of the international ...
