Why is nanotechnology revolutionary?

Consider this: Graphite and Diamond are both made up of carbon. Graphite is soft, diamond is hard. Graphite is black, diamond is sparkling and transparent. Graphite is a good conductor of electricity and a bad conductor of heat. Diamond is a bad conductor of electricity and a good conductor of heat. Why such diagramatical difference in properties The reason is found in the atomic construction of the two substances. Graphite is arranged in sheets - like placing sheets of a newspaper one on top of the other. The sheets can slide over one another, so graphite is soft; the presence of free electrons between the sheets means that graphite is a good conductor of electricity. Diamond, on the other hand has its carbon atoms arranged as a crystal lattice. Hence there is no scope for movement of any atoms, no free electrons, and the tightly defined path between the atoms makes diamond a good conductor of heat. When scientists observed this phenomenon, it made them understand the power inherent in atomic arrangements. Soon experiments were underway to create new substances by rearranging atoms in ways not found naturally. The result was the formation of substances with hitherto unheard of properties. For example, a nanomaterial called a carbon nanotube, has enabled the creation of a tennis racket one sixth the weight of current rackets, yet twice as strong. The racket, made by the manufacturing giant Wilson, was used by Roger Federer in the 2009 Wimbledon. The creation of new materials means that we can now play with the very laws of nature. Things need not behave the way they did till now. Have you ever heard of plastic conducting electricity? Molecule-sized transistors? Robots so small that they are invisible performing surgery? All this is now possible with the help of nanotechnology.
