The unusual phenomenon was first observed in 1665 by Christiaan Huygens (1629-1695), according to LiveScience.

After 350 years two Portuguese researchers believe that pendulum clocks eventually swing together because of sound pulses that travel through the wall from clock to clock.

A new study was finally able to detect how two pendulum clocks on the wall can move perfectly in sync with one another. No matter how the clocks started, the Dutch scientist noticed that within about 30 minutes their pendulums wound up swinging in precisely opposite directions.

“Nobody tested properly the idea of clocks hanging on the same wall”, co-author Henrique Oliveira, a mathematician at the University of Lisbon was quoted as telling Live Science.

The said distance is the smallest possible measurement that can ensure that the two pendulums would not bump into each other. The anchorman- pendulum clocks employed were mass- powered and, in line with the experts, power that may last for up to five days can be provided by one mass vacation. The clocks won’t die down instantly as it would take approximately one day for it to relax under its final frequency after winding.

These waves that are sound matter them to synchronization and in the end can affect the style in which the pendulum swings. The period is adjusted by lengthening the actual pendulum through manipulation of the screws at the bottom of the clocks.

“We assume that the coupling is obtained through the exchange of sound pulses between the clock propagated through the rail”, write the researchers in their paper.

In this case, researchers argue that tiny pulses created by ticking clocks travel through the wood connecting them and slowly pushed the pendulums into their synchronized swing. Over uncovering the mystery behind a problem that was clinical that was old, their review was additionally not unable to boost comprehension about how other types of oscillators function, he included.
