In some physical systems, even elements quite distant from one another are able to synchronize their actions. At a first glance, the phenomenon looks rather mysterious. Using a network of simple electronic oscillators interconnected as a ring, researchers from the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow have shown that, in fact, remote synchronization can, at least in certain cases, be explained quite clearly.
