Steve Strogatz's book provides a fascinating overview of how spontaneous rhythms occur in nature. The author touches on a wide range of scientific and mathematical issues, but focuses on the phenomenon of synchronization, which is observed in the glow of fireflies, the rhythmic beating of hearts, and the movement of planets and asteroids.

The book will be useful to everyone who is interested in the natural sciences and wants to better understand the structure of the world around them. It is published in Russian for the first time.
