Researchers Solve 300-Year-Old Mystery Behind Synchronous Swinging Of Pendulum

For three hundred years or more scientists have been wondering why clocks do something odd: when two pendulum clocks are hung on the same wall they sync up, with one pendulum swinging to the left and the other to the right.

Christiaan Huygens was the first person to observe the synchronization of wall clocks in 1665 when he was lying in bed with a minor illness.

Researchers Henrique M. Oliveira and Luís V. Melo performed the study by devising an experiment that used a standard optical rail rigorously attached to the wall where two pendulum clocks with a distance of 230 millimeters were also fixed. Huygens observed no matter where the two wall clocks were placed or when they started, the devices always swayed in sync. The time is by stretching the specific pendulum through treatment of the screws in the bottom of the clocks, modified.

But according to a new paper published on July 23 in the journal Scientific Reports-which builds on earlier research, including a study published in 2002-this is the correct explanation: sound waves generated by the movement of one pendulum travel through the wall to perturb the movement of the other until the pendulums are moving in opposition. These sound pulses can interfere with the swings of the pendulums, eventually making them to synchronize. The dunes driving one pendulum with time together with the other vacation and come back to the metal club.

“We could verify that the energy transfer is through a sound pulse”, Mr Melo told the Guardian. 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.

The clock swinging phenomenon was first noted by Christiaan Huygens in 1665. At the time it was the most accurate timepiece ever made, gaining or losing less than one minute a day.
