Newton Rules Biology

Book excerpt: This book invites biologists to look at their science from the point of view of Newtonian physics. Because biology occupies that range of scale over which Newton's mechanics can account for physical processes to a level of precision appreciably higher than that to which biologists are accustomed, this is an exercise that can yield new insights and a fuller understanding of biological processes. Writing in a clear, accessible style, the author demonstrates the operation of physical laws at all levels, from cellular structures to entire ecosystems. In fact, although ecology might seem an unpromising field for a mechanical approach, it is here that considerations of such Newtonian concepts as mass and rates of flow are most valuable, yielding new information on the constraints to the dynamics and development of integrated systems, including those that contain human populations.
