Nanosystems: Molecular Machinery, Manufacturing, and Computation
"Devices enormously smaller than before will remodel engineering, chemistry, medicine, and computer technology. How can we understand machines that are so small? Nanosystems covers it all: power and strength, friction and wear, thermal noise and quantum uncertainty. This is the book for starting the next century of engineering." - Marvin Minsky
MIT Science magazine calls Eric Drexler "Mr. Nanotechnology." For years, Drexler has stirred controversy by declaring that molecular nanotechnology will bring a sweeping technological revolution - delivering tremendous advances in miniaturization, materials, computers, and manufacturing of all kinds. Now, he's written a detailed, top-to-bottom analysis of molecular machinery - how to design it, how to analyze it, and how to build it. Nanosystems is the first scientifically detailed description of developments that will revolutionize most of the industrial processes and products currently in use.
This groundbreaking work draws on physics and chemistry to establish basic concepts and analytical tools. The book then describes nanomechanical components, devices, and systems, including parallel computers able to execute 1020 instructions per second and desktop molecular manufacturing systems able to make such products. Via chemical and biochemical techniques, proximal probe instruments, and software for computer-aided molecular design, the book charts a path from present laboratory capabilities to advanced molecular manufacturing. Bringing together physics, chemistry, mechanical engineering, and computer science, Nanosystems provides an indispensable introduction to the emerging field of molecular nanotechnology.

Free energy . The free energy for a system of two wells can conveniently be
written as the sum of the free energy of each well ( assuming unit probability of
occupancy ) , weighted by the actual probabilities of occupancy , plus an entropic
The feasible reduction in free energy is , however , lessened by the entropic cost
of orienting the solvent molecules . A preorganized structure ( Cram , 1986 ) , in
contrast , can equal the electrostatic effects of a good solvent without imposing ...
( Note , however , that all energy has mass , and thus can be used to do work by
virtue of its gravitational potential energy ; this caveat , however , is of no practical
significance unless a really deep gravity well is available . ) See ' free energy .
