The pendulum clock, arguably, was the first experimental indication we had that gravity is not uniform over the surface of the Earth. Even before the advances of Isaac Newton, ...

Each time that energy pulse travels, it tends to push one clock's pendulum in time with the other. The experiment takes up to 18 hours or even days to run, because the clocks synchronize slowly.

In the 17th century, Christiaan Huygens, inventor of the pendulum clock, noticed a curious phenomenon. When two identical pendulum clocks are mounted next to each other on a wall, their swings ...
