A unique introduction for general readers to the underlying concepts of nanotechnology, covering a wide spectrum ranging from biology to quantum computing. <br>The material is presented in the simplest possible way, including a few mathematical equations, but not mathematical derivations. It also outlines as simply as possible the major contributions to modern technology of physics-based nanophysical devices, such as the atomic clock, global positioning systems, and magnetic resonance imaging. As a result, readers are able to establish a connection between nanotechnology and day-to-day applications, as well as with advances in information technology based on fast computers, the internet, dense data storage, Google searches, and new concepts for renewable energy harvesting. <br>Also of interest to professionals working in law, finance, or teaching who wish to understand nanotechnology in a broad context, and as general reading for electrical, chemical and computer engineers, materials scientists, applied physicists and mathematicians, as well as for students of these disciplines.<br>
