This ensures the pendulum doesn’t change length with temperature, but it still only brings the clock into the 0.1 second/day range.

Due to this “time base generator,” clocks are connected to an irreversible process, meaning that they add entropy to the universe. In the case of a grandfather clock, for example, the pendulum ...

As mechanical clocks became more sophisticated, they began to feature hour and minute hands, allowing for more precise timekeeping. The introduction of the pendulum clock by Dutch scientist ...

When a pendulum clock is running properly, you should hear a rhythmic and even "TICK-TOCK." If you're hearing "tick-TOCK, tick-TOCK," your clock is not going to be running for long.

Witness the intricate build of a fully working LEGO pendulum clock designed for precision and durability. This project features an enhanced escapement mechanism paired with a smooth gear train ...
