"All Together Now: Clap": Review of *Sync* by Steven Strogatz and *SixDegrees* by Duncan J. Watts. Reviewed by Larry Marshall. *Discover,* April 2003.

Marshall reviews two books---*Sync: The Emerging Science of SpontaneousOrder,* by applied mathematics professor Steven Strogatz (CornellUniversity) and *Six Degrees: The Science of a Connected Age,* bysociologist-mathematician Duncan J. Watts (Columbia University). Strogatzstudies synchrony ("a phenomenon long familiar to physicists under the name ofresonance") and Watts studies networks using mathematical models. "BothStrogatz and Watts believe that the calculus of connectivity, along with anunderstanding of how the elements of a network react to stimuli, is the nextbig idea in natural and social science."
