It covers a lot of topics and some of them are entertaining. But seems unfocused and hard to get a big picture.

Author Steve Strogatz's book "Sync" ostensibly concerns the spontaneous synchronization of oscillators, where an "oscillator" is anything that exhibits periodic behavior -- be it a clock, a flashing firefly, or an electron in a superconductor.

The book is clearly modeled on James Gleick's book "Chaos": both books follow various researchers who originally work in isolation but who gradually recognize that they are investigating different aspects of the same phenomenon. As Gleick did for chaos, Strogatz tries to portray spontaneous synchronization as a fundamental, unifying phenomenon in nature. However, many of Strogatz's examples are unimpressive: sleep patterns, the coordinated flashing of lightning bugs, etc. In the more important cases -- the heart's pacemaker cells, phase transitions -- the mechanisms' details haven't been elucidated, so it's not clear how synchronization actually operates. Gradually Strogatz wanders: He argues that in order to progress, science should abandon its traditional analytic approach of investigating the bits of a system and instead should investigate the interactions between the bits; in this connection, he discusses the game "6-degrees of separation," in which very different people are "linked" by chains of acquaintances.

(Strogatz also follows Gleick's footnote format, which is a nuisance.)

In reading this book, I had hoped to find deep insights from a principal investigator in the field; instead, I found entertainment for the math-phobic.

What I found most interesting about Strogatz's sync theory was the position that it did not require an extensive measure of complexity in order to achieve synchronization. It merely required a critical mass or critical repetition in order to effectuate a phase transformation. The phenomenon of resonance performs similarly. Synchronization may be a form of resonance which has been overlooked, thus far, in our reality (biosphere).

What a fun book. Strogatz has managed to talk about the leading edge of mathematical modeling without a single equation! He uses a comfortable prose and never strays too far from the story of his research. The reader is treated to a view of the way that the world network of scientists organizes itself within areas of research and finds unions where research from one speciality can contribute to another. Who would have thought that the western power grid, the Internet Movie Database and the nervous system of a worm called C. elegans could be effectively modeled with the same operational principles.

This book gave both nature and theoretical explanation of what sync is and how it might
happen. Of course, its raminifaction still need a lot of exploration. This book is a good start and definite a good read for scientific inquiring mind. Read it and you know if you sync with this book.
