After more than three centuries, scientists say they have figured out why pendulum clocks hung on the same wall tend to sync up--with one clock's pendulum swinging to the left just as the other swings right. No matter how the clocks started, the Dutch scientist noticed that within about 30 minutes their pendulums wound up swinging in precisely opposite directions. As Dr.

Almost years ago, Dutch inventor and scientist Christiaan Huygens observed that two pendulum clocks hanging from a wall would synchronise their swing over time. What causes the phenomenon has led to much scientific head-scratching over the centuries, but no consensus to date. A study in the journal Scientific Reports has proposed a solution: the pendulums transfer energy to one another through sound pulses.

The year-old mystery of why pendulum clocks hanging from the same wall synchronize over time may finally be solved, scientists say. InDutch physicist Christiaan Huygensinventor of the pendulum clock, was lying in bed with a minor illness and watching two of his clocks hanging on a wall, said Henrique Oliveira, a mathematician at the University of Lisbon and co-author of a new study detailing the findings. Huygens noticed something odd: No matter how the pendulums on these clocks began, within about a half-hour, they ended up swinging in exactly the opposite direction from each other.

A pendulum clock is a clock that uses a pendulum, a swinging weight as its timekeeping element. Pendulum clocks had to be stationary and level to operate. Any motion or accelerations will affect the motion of the pendulum causing loss or gain of pendulum speed and beat.

Introduction Did you know that playground swings can provide a good lesson in physics—as well as lots of fun? The back-and-forth motion of a swing is an example of a pendulum. We see pendulums in other areas of our lives as well, such as in grandfather also known as longcase clocks.

Pendulum clocks have been used to keep time sinceand they have not changed dramatically since then. Pendulum clocks were the first clocks made to have any sort of accuracy. When you look at a pendulum clock from the outside, you notice several different parts that are important to the mechanism of all pendulum clocks:.

Last updated: December 15, T ick tock, tick tock—that's the sound we think of when we think of clocks, even though the vast majority of modern timekeepers make hardly any sound at all. Not so long ago, virtually every clock and watch made a tick-tock noise because it was completely mechanical rather than electrical or electronic.
