The incredible shrinking bee

Description:

"Because vertebrate circulations do not work when shrunk to insect sizes, insects may help us design our smallest machines. Within small bodies, bees separate diffusing substances in an open cavity assisted by locomotion and the beat of the heart. The open anthropoid circulation, however, is most efficient when shrunk until its large three-dimensional volume of blood turns into a two-dimensional film of fluid covering only the internal surfaces. This transformation increases the chances to near-certainty that molecules can diffuse from one point to another without getting lost." "The Incredible Shrinking Bee expresses mathematics in words so the most readers can compare today's microelectromechanical (MEMS) devices with a honeybee's circulation, introducing ideas of biominiaturization to workers interested in developing compact energy and chemical system."--Jacket.
