Nanosystems Nanosystems: molecular machinery, manufacturing, and computation by K. Eric Drexler pp. Wiley Interscience, , hardcover or paperback. Click here for more information on nanotechnology. The detailed analyses show quantum chemists and synthetic chemists how to build upon their knowledge of bonds and molecules to develop the manufacturing systems of nanotechnlogy, and show physicists and engineers how to scale down their concepts of macroscopic systems to the level of molecules. 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. This multidisciplinary synthesis opens the door to the new field of molecular manufacturing. It is essential for anyone contemplating research in this area Over 10, copies in print. Nanosystems was reviewed by James B. Drexler's approach is distinguished from conventional chemistry in that complex structures are to be made by using programmable "nanoscale mechanical systems to guide the placement of reactive molecules" to about 0. The objective of the book is to present a theoretical foundation for "molecular manufacturing", which Drexler also calls "molecular nanotechnology". The objective is not to present a detailed review of recent experimental progress in the many disciplines that converge on what is being increasingly termed "nanotechnology".
