The inertial mass, sometimes referred to as the seismic mass, is arguably the most critical part of a seismograph. This mass ...

Physicists at the University of Toronto have developed technology that could power a new generation of optical atomic clocks ...

The familiar tick-tock of wall clocks originates from the escapement mechanism, which controls gear movement in precise steps ...

The clock had been built for the owner of one of Portland’s most prominent buildings of the early 20th century.

Timekeepers once trusted wobbling pendulums and vibrating quartz. Now, the world’s best quantum clocks probe energy gaps inside single atoms, counting oscillations with parts‑per‑quintillion precision ...

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 ...
