Nanotechnology is the science and technology of small things. Moreover it is the science , engineering, and technology conducted at the Nano Scale, which is about 1-100nm (nanometer) or a billionth of a meter. For comparison, A human hair is about 60-80,000 nanometers wide. A sheet of newspaper is about 100,000 nanometers thick. If a marble were a nanometer, then one meter would be the size of the Earth. 1 inch = 25 400 000 nm. 10 -9 m is 3 atoms long. It’s hard to imagine just how small nanotechnology is . The microscopes needed to see things at the Nano scale were invented relatively recently about 30 years ago. But the idea and the concept behind nanotechnology started with a talk entitled “ There’s Plenty of Room at the Bottom ” by physicist Richard Feynman at an American Physical Society meeting at the California Institute of Technology (CalTech) on December 29, 1959, where he described a process in which scientists would be able to manipulate and contro...
