A team of researchers claim they have successfully solved the mystery associated with pendulum clocks. Scientists since long have been baffled by the point who does swing of two pendulum clocks mounted next to each other on a wall eventually become synchronized.

According to Discovery News, almost 350 years ago, Dutch scientist and inventor Christiaan Huygens noted that two pendulum clocks hanging on the same wall would synchronize their swings after a period of time.

Huygens also noted that pendulum of one clock will tend to swing left the moment a second clock's pendulum moves right. He called the effect 'an odd kind of sympathy' in his letter to the Royal Society, which has remained unexplained for centuries.

Dr. Henrique M. Oliveira, co-author and mathematician at the University of Lisbon, said in explanation that the two clocks interact, giving two 'kicks', one in one direction and another one in the opposite.

He stated that the pendulums start swinging in opposite directions only when the clocks are at phase opposition where the effects of the perturbation get cancelled.

The study published in the nature journal Scientific Reports proposed a solution that the pendulum transfers their energy to one another via sound pulses. Those sound pulses might transfer from one clock to another, adjusting the swing of the pendulums until these synchronize accordingly.

The findings revealed that very minor interactions can add up and result to the synchronization of very large systems. The same basic principles are also present in fields like economics, biology and electronics. Human body cells and other complex systems can also have the same concept.
