By 2015, nanotechnology could be a $1 trillion industry. Now, renowned nanotech pioneer Mark Ratner and technology entrepreneur Daniel Ratner show you how nanotech works, why it's so exciting, what's new, and what's next. They survey the entire fieldtechnology and businesscovering nanobots, molecular electronics, quantum computing, biostructures, nanotubes, molecular motors, nanosensors, and many other breakthrough applications. They provide easy-to-understand explanations of every key concept, plus dozens of visuals that bring nanotechnology to life. Coverage includes: A simple, brief, almost math-free introduction to nanotech science; "Grand tour" of nanotech R & D, from "smart materials" to DNA computing; Breakthrough biomedical applications, including neuro-electronic interfaces and new drug delivery systems; Current and emerging nanotech systems for optoelectronics and communications; Nanotech here and now: nano-enhanced tennis balls, suntan lotions, and other products already in the market; A realistic assessment of nanotech investment opportunities for the short- and long-term; Ethical issues associated with nanotech research and product development.

Title : Nanotechnology -- a Gentle Introduction To The Next Big Idea
Authors : Mark Ratner and Daniel Ratner
This is a remarkable book by two remarkable people. Each is extremely accomplished in his respective field. I feel they have accomplished their aim -- that being, a straightforward explanation of an esoteric and exciting field of science that has promise of far-reaching implications in our everyday lifestyle and experience.
Nanotechnology is the field that deals with matter at the most fundamental level; that is the realm of atoms, the building blocks of molecules. Nano by definition means one billion of a meter. A meter is just over a yard in length. 2 1/2 cm. equals 1 inch. A millimeter is 1 1000th of a meter. A nanometer is one billion of a meter. That is several times smaller than a human hair.
Why is this important? We can’t see things that small except with special, high-powered microscopes. Well, the fact is we live in a material universe and it’s at the nano level that it all begins. If things at that level can be understood and manipulated, and in some instances customized, it is possible to fabricate useful materials of a large variety that we could find beneficial.
This field of study is predicated on work by a famous physicist, Richard Feynman, over 40 years ago. His field was quantum electrodynamics. At the quantum level -- in the realm of photons -- the conventional rules of physics no longer applied. Feynman predicted that by the year 2000 nanotechnology would be the new frontier. Up to this time the necessary tools just weren’t available.
Rita Colwell, the director of the National Science Foundation is quoted as saying --“nanotechnology is truly a portal opening to a new world”.
The book gives a cursory, yet exciting, overview of the subject. There are interesting graphics and color illustrations that help us get an idea of what is involved. Several institutions as well as individual investigators are named. Companies that are heavily engaged in research and application of “nano” include names like IBM, Merck, Kraft, 3M and Agilent (formerly Hewlett-Packard) Institutions include Northwestern, Harvard, MIT, Rice, Illinois, Perdue, Cornell, UCLA, etc.
The hype about nano is increasing exponentially yet it is still little-known by the general public. There are many things on the shelf today that have been made possible by the knowledge extant. Gore-Tex has been around for several years now and it’s ability to allow water vapor to escape yet keep water out has been a boon to outdoor people.
This is another book not aimed at everyone but for those interested in cutting-edge science it is worth the time. Contains Index and glossary as well as related references. 165 pp.
