Have you ever heard that clocks ticking at different beats will eventually synch up to tick in time? Well, it’s true.

Christiaan Huygens, the Dutch physicist who first identified this process using pendulum clocks, called this curiosity ‘the sympathy of the clocks,’ although what he actually identified was the phenomenon of entrainment, an exceptionally cool rhythmic synchronization that also happens to humans and animals: fireflies lock into a same beat, humans adjust their rhythmic speech patterns to each other in conversation and our brain waves, when entrained with certain frequencies, create in us states of deep peace and tranquility.
