Physical Constraints

Part of the Biological and Medical Physics, Biomedical Engineering book series (BIOMEDICAL)


For a microscopic organism living in water, such as E. coli, constraints imposed by physics are immediate and compelling. These limit the means by which cells are able to swim, define the distance that they must move to determine whether life is getting better or worse, and set the time scale for their behavioral response. To appreciate what E. coli has accomplished, we need to look at some of the physics that E. coli knows.
