The 18th-century horologist John Harrison claimed that he could make the world's most accurate pendulum clock, but his methods were scorned for hundreds of years—until someone proved him right.

“Every clock needs two components: first, a time base generator—such as a pendulum in a pendulum clock, or even a quantum oscillation,” Marcus Huber, the senior author of the study from TU Wien, said ...

It may be I just didn’t spend enough time adjusting the pendulum length–I hate to stop the pendulum and turn that little nut. I agree that at least the nicer of my two clock is very stable.

John Harrison, one of the world’s greatest clockmakers, claimed to have designed the perfect pendulum clock in the mid-18th century. Instead of being celebrated, Harrison’s plans were ...

The pendulum of a pendulum clock generates a little heat and disorder among the air molecules around it, and every laser beam that reads the state of an atomic clock generates heat, ...

Designed 300 years ago but completed only now, this chronometer officially became “the most accurate mechanical clock with a pendulum swinging in free air”, certified by Guinness World Records.

Get Instant Summarized Text (Gist) Using two distinct time scales in quantum clocks—analogous to second and minute hands—enables exponential gains in accuracy relative to entropy and energy ...

Clocks in Galileo’s era told time only to the nearest quarter hour and allowed only crude rate regulation. The pendulum-regulated clock, first conceived by Galileo and then realized by Christian ...
