Based on the thinking of, among others, the Nobel Prize-winning physicist Richard Feynman, and pioneered by Eric Drexler, the science of nanotechnology promises man control over the structure of matter. At its heart is the creation of an empire of tiny programmed robots called assemblers, so small that they will be able to work with individual molecules of matter. A race of these nano-robots could be programmed to produce any substance, structure or entity allowed by the laws of nature. The author of this book has followed nanotechnology since its beginnings. He assesses the main personalities from the earliest theories to work being done today in major research institutions, taking readers on a journey that could lead to the biggest life-changing development since the harnessing of electricity. Ed Regis is also the author of "Who Got Einstein's Office?" and "Great Mambo Chicken and the Transhuman Condition: Science Slightly Over the Edge".
