The Technology Roadmap for Productive Nanosystems defines “productive nanosystems” as functional nanometer-scale systems that make atomically-specified structures and devices under programmatic control, ie they perform manufacturing to atomic precision. Present-day technologies are limited in various ways. Large atomically precise structures exist, in the form of crystals. Complex 3D structures exist in the form of polymers such as DNA and proteins. It is also possible to build very small atomically precise structures using scanning probe microscopy to manipulate individual atoms or small groups of atoms. But it is not yet possible to combine components in a systematic way to build larger, more complex systems. Principles of physics and examples from nature both suggest that it will be possible to extend atomically precise fabrication to more complex products of larger size, involving a wider range of materials. An example of progress in this direction would be Christian Schafmeister’s work on bis-peptides. (From Wikipedia, the free encyclopedia) Video Rating: 5 / 5
Strange Interlude is one of the few modern plays to make extensive use of a soliloquy technique, in which the characters speak their inner thoughts to the audience. Some productions have had the actors carry masks to distinguish their spoken dialogue from their soliloquies, although most productions allow the distinction to be made through acting style alone. The soliloquies in Strange Interlude mostly take the form of relatively brief side comments, not of lengthy speeches in the Shakespearean manner. People have been worried about nanotechnology for quite some time now; nano-asbestos, advanced nano-enabled weapons, and self-replicating gray goo nanobots that accidentally go out of control. But what if everything goes right? What if nanotubes and nanoparticles are functionalized to stay out of the ecosystem? What if there are no major wars? What if nanoreplicators are never built, or if they are, they use modern error correction software to never mutate? What happens if nanotechnology fulfills humanitys desires perfectly? In the next decade or so, a new type of desktop appliance will be developed—a nanofactory that consists of very many productive nanosystems—atomically precise nanoscale machines that work together to build bulk amounts of atomically precise products. The Foresight Technology Roadmap for Productive Nanosystems has identified a number of different approaches for building these atomically precise systems of machines that can produce other nanosystems www … Video Rating: 5 / 5
