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.
