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

[Stephen Hobley] has been experimenting with an electromagnetic pendulum in order to build himself a clock. Through the course of his experiments, he has learned quite a bit about how pendulums fun… ...

“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 ...

Pendulum clocks, which were created in the mid-17th century, were the first kind of precision timekeeping that led to the clocks that we have today. So there you go.

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 ...

Powered by one single pendulum clock, it provides a realistic image of the positions of the Sun, the Moon, the Earth and five other planets (Mercury, Venus, Mars, Jupiter and Saturn). The planets ...
