Synopses & Reviews
Our human technology has emerged from ten thousand years of design, trial and error. Nature's mechnical designs, the function of plants and animals, are billions of years older. Both "technologies" share the same physical environment the same materials, atmosphere and temperature range and both are subject to the same gravitational pull. But they've turned out to be wildly dissimilar.
Human designers love right angles, but nature is typically round, curved and its angles are more diverse. The wheel enables a huge amount of our technology, yet nature's only true wheels lie within tiny bacteria. Most of our water vessels sail buoyantly across water's surface, while nature typically swims submerged. Our hinges turn because hard parts slide around, wheras natural hinges (such as a rabbit's ear) turn by bending their flexible materials.
Author Steven Vogel examines the many questions that arise from these differences: why have these technologies taken such separate paths? Is nature the better designer or does homo sopiens, being sapient, get the nod? Cat's Paws and Catapults is about the ways living things work and walk, run, jump and fly and how they grow. It introduces the reader to the field of biomechanics and explains how the nexus of physical law and historical accident determine the designs of both people and nature. It asks, in the end, how looking at nonhuman natural technology might enrich our understanding of what we do and have done.
