What will Assemble the Future?
|| Nanotechnology is an essentially modern scientific field that is constantly evolving as commercial and academic interest continues to increase and as new research is presented to the scientific community. The field’s simplest roots can be traced, albeit arguably, to 1959 but its primary development occurred in both the eighties and the early nineties.
The first use of the concepts in 'nano-technology' (but predating use of that name) was in "There's Plenty of Room at the Bottom," a talk given by physicist Richard Feynman at an American Physical Society meeting at Caltech on December 29, 1959.
Feynman suggested that it will eventually be possible to precisely manipulate atoms and molecules. Moreover, in an even more radical proposition, he thought that, in principle, it was possible to create "nano-scale" machines, through a cascade of billions of factories. According to the physicist, these factories would be progressively smaller scaled versions of machine hands and tools. He proposed that these tiny machine shops would then eventually be able to create billions of tinier factories.
In the 1980s the basic idea of this definition was explored in much more depth by Dr. K. Eric Drexler, who promoted the technological significance of nano-scale phenomena and devices through speeches and the books.
In 1981, Drexler published his first article on the subject in the prestigious scientific journal, Proceedings of the National Academy of Sciences. Titled "Molecular engineering, an approach to the development of general capabilities for molecular manipulation", Drexler's publication essentially expanded the idea of molecular manufacturing by integrating modern scientific ideas with Feynman's concepts, Drexler states that molecular manufacturing and the construction of "nano-machines" is a product of an analogous relationship "between features of natural macromolecules and components of existing machines. In addition, Drexler includes a table that outlines by function the molecular equivalents to macroscopic technologies.
Drexler pointed out the resulting nanotechnology can help the life, spread beyond earth a step without parallel since life spread beyond the seas; it can let our minds renew and remake our bodies, with synthesize immortality.
Essentially, Drexler presented, albeit simplistically, that if atoms are viewed as small marbles, then molecules are a tight collection of these marbles that "snap" together, depending on their chemical properties. When snapped together in the right way, these molecules could represent normal-scaled tools such as motors and gears. Drexler suggested that these "atomic" tools and machines would operate just as their larger counterparts do.
Some scientists have criticized Drexler's visions as impossible and harmful. Richard Smalley has led this movement against Drexler's almost sensationalist vision of molecular manufacturing. In their open debate in 2003, Smalley writes almost scathingly, "you cannot make precise chemistry occur as desired between two molecular objects with simple mechanical motion along a few degrees of freedom in the assembler-fixed frame of reference.
In addition to the criticism of Drexler's vision of molecular manufacturing, three important developments that were independent of Drexler's paper helped turn nanotechnology into this broad field, today.
The Scanning Tunneling Microscope: With this technology, individual atoms could be clearly identified for the first time. Despite its limitations (only conducting materials), this breakthrough was essential for the development of the field of nanotechnology because what had been previously concepts were now within view and testable and the idea of a ribosome as an example of a natural molecular machine, and note that atomically precise final products do not require precise control of all aspects of the chemical reaction.
While nanotechnology came into existence through Feynman's and then Drexler's vision of molecular manufacturing, the field has evolved in the 21st century to largely include research in chemistry and materials science as well as molecular engineering. As evidenced by Smalley's debate, this evolution is partly a response to the criticism of Drexler's views in both Engines of Creation and the Foresight Institute
Drexler and therefore Feynman did not have a direct role in the three most important breakthroughs in nanotechnology, the invention of the STM , the invention of the AFM, and the first manipulation of atoms.
It can be also interesting to point out, one of the biggest discoveries a few days ago on Majorana particles; Dutch Scientists think they may finally have seen evidence for a famously elusive quarry in particle physics. The Majorana Fermion was first predicted 75 years ago a particle that could be its own anti-particle simultaneously.
This new discovery can lead to scientific development changing our current binary computer language into a revolutionary new type of quantum language by enabling the compressing of data hundreds if not thousands of times thanks to the Majorana Fermion For its discovery enables as to use it for a purpose.

HowStuffWorks: How Nano Technology works?
||There's an unprecedented multidisciplinary convergence of scientists dedicated to the study of a world so small, we can't see it -- even with a light microscope. That world is the field of nanotechnology, the realm ofatoms and nanostructures.Nanotechnology i¬s so new, no one is really sure what will come of it. Even so, predictions range from the ability to reproduce things like diamonds and food to the world being devoured by self-replicating nanorobots.
In order to understand the unusual world of nanotechnology, we need to get an idea of the units of measure involved. A centimeter is one-hundredth of a meter, a millimeter is one-thousandth of a meter, and a micrometer is one-millionth of a meter, but all of these are still huge compared to the nanoscale. A nanometer (nm) is one-billionth of a meter, smaller than the wavelength of visible light and a hundred-thousandth the width of a human hair [source: Berkeley Lab].
As small as a nanometer is, it's still large compared to the atomic scale. An atom has a diameter of about 0.1 nm. An atom's nucleus is much smaller -- about 0.00001 nm. Atoms are the building blocks for all matter in our universe. You and everything around you are made of atoms. Nature has perfected the science of manufacturing matter molecularly. For instance, our bodies are assembled in a specific manner from millions of living cells. Cells are nature's nanomachines. At the atomic scale, elements are at their most basic level. On the nanoscale, we can potentially put these atoms together to make almost anything.
In a lecture called "Small Wonders:The World of Nanoscience," Nobel Prize winner Dr. Horst Störmer said that the nanoscale is more interesting than the atomic scale because the nanoscale is the first point where we can assemble something -- it's not until we start putting atoms together that we can make anything useful.
In this article, we'll learn about what nanotechnology means today and what the future of nanotechnology may hold. We'll also look at the potential risks that come with working at the nanoscale.

Who/What are NanoAssemblers;
Nano Technology – Genetic Engineering – bioTech – NanoBioTech – Material Engineering – Quantum Physics – Quantum Information Technology – Information theory – Computers & Robots – Measurement of Nature – BlackHoles – Schwarzschild radius – Consciousness theory – Smart Materials
What will happen when BioTechnology & NanoTechnology & Genetic Engineering & Artificial Intelligence work togethers?
We will have new kind of life base on nano robots instead of our biological cells. It just need to make them smart with learning ability. And nowadays we have this technology of artificial Intelligence. When your softwares find new data and get them (called Auto Update), means they understand what are their requirements so update themselves and get new features and abilities. For example your OS cannot understand Chinese but it can get a languages package to get Chinese. The ability of detection of updates (new data) is a smart ability.
When NanoAssemblers as small computers get this ability they can do everything they want.
Assemblers will define new kind & methods of life. Based on tiny robots strings like DNA & RNA. It s new consciousness of matter when intract with data & waves and etc. It s consciousness of smart materials. These we lots of smarter materials; on glasses, smartphones, clothes, drugs & etc. When a drug detect exact coordinates of concerns and attack to it. When smart materials react(move) according to light or sound or ...
For assemblers we two general model to create them: like Bacteria & Virus.
Baceria like ones can just do that we order and confirm without growing up (get new data; update) But Virus like ones can upgrade themselves if necessary; they can get new data so new abilities and features. And they can copy them structure to redesign new structure always. And it s what we say cloning.
It s not necessity to say examples cause you can suppose everythings.
NanoAssemblers can govern on Nature. With super ability cause they can grow up so fast and make themselves more & more compatible because they live in Quantun scale and more quantic than us. So they can live from ice to sun, from labs to schwarzschild Radius. They can use elementary particke like neutrinos to communicate so they send us message from somewhere that we cannot imagine, from our bodies to BlackHoles.
And it s measurement of Nature |
*Physicsism will work on NanoTechnology more & specially.
From basic & simple concepts for introduction to advance levels.
