Similarly, the most critical property of biological clocks-which rhythmically organize the processes of life-is their ability to reset on cue. This ability allows enables biological clocks to regain synchrony with a changing environment (as when we travel across time zones) or to maintain the alignment between certain physiological rhythms and the natural solar day. In The Timing of Biological Clocks, Winfree explores circadian rhythms. In reporting...

Describes how and why scientists trace seismic activity and measure the extent and patterns of seismic waves, illustrating how basic geological lessons are learned.
