New study shows nanoscale pendulum coupling

In 1665, Lord Christiaan Huygens found that two pendulum clocks, hung in the same wooden structure, oscillated spontaneously and perfectly in line but in opposite directions: the clocks oscillated in anti-phase. Since then, synchronization of coupled oscillators in nature has been described at several scales: from heart cells to bacteria, neural networks and even in binary star systems -spontaneously synchronized.
