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.

Transition state theories The previous chapter examined the effects of thermal
excitation and quantum uncertainty in systems that can be described as points
oscillating in a single potential well . This section examines thermal and quantum
transition state theory define different transition surfaces . ( Note that this surface
has one fewer spatial dimension than the potential energy surface ; the next
section speaks of volumes that correspond to regions of the PES and transition ...
bath ) oscillate across the transition surface several times . Other trajectories may
cross the surface and be promptly reflected back into the originating well . These
crossings are transitions according to the above definition , but not in any ...
