The Dance of Molecules: How Nanotechnology Is Changing Our Lives

Sargent, visiting professor of nanotechnology at MIT, persuasively argues that advances in nanotechnology are occurring at a dizzying rate and have the potential to transform almost all aspects of human society, from health care to warfare. The book examines cutting-edge science in health, the environment and communications. Sargent's optimism knows almost no limits. He predicts that with nanotechnology's ability "to design and build matter to order," scientists will soon be able to prescribe nano-size drugs that will identify and kill single cancerous cells long before they can do any harm, and regenerate nerve cells to cure spinal cord injuries. Further, Sargent says, "new technologies may allow ground-based warfare without people." Throw in a limitless energy supply and a fully integrated computer and communications system that will become an integral part of humans, and you have a utopia almost beyond belief. Indeed, with only a few pages devoted to possible negative environmental consequences of runaway nanotechnology, Sargent's utopia is beyond belief. Although his exuberance is somewhat infectious, he tries a bit too hard to make his writing witty, such as describing an optical detector as "a voyeur, a castrato ogling the photon but under-equipped to seduce it."
