A great introduction to a the concept of synchronization. Very interesting and educational. Many references for follow up (like Kuramoto's model).Strogatz does an excellent job in describing a rather complex concept in simple terms. I am interested in the area of non-linear systems but was totally unaware of its existence until I watched by chance a TED talk by Strogatz on Sync.(highly recommended easily found on the net). The talk was fascinating.. the book takes you deeper into the world of synchronization. An eye opening experience.
