DEFINITION :

The computer has already gone through a dynamic revolution. Thirty years ago, computers were the size of a room and incredibly slow. Few people probably would have imagined supercomputers that can do over a trillion calculations per second. Today, the average person's desktop computer is more powerful than the fastest computers were 30 years ago. The only way this can continue is if a new type of computer is developed. This computer is known as a nano computer.

NANOTECHNOLOGY : Nanotechnology is an exciting emerging science and technological field that is making a splash in 2002. Nanotechnology involves man’s ability to create and manipulate molecules structures to create potentially new materials, devices, machines or objects. A nanometre is a billionth of a metre, that is, about 1/80,000 of the diameter of a human hair, or 10 times the diameter of a hydrogen atom. . If you blew up a baseball to the size of the earth, the atoms of the baseball would be about the size of grapes. If you could take a ruler and measure 10 atoms side by side, you would have a nanometer. The World is on the brink of a technological revolution beyond any human experience. It has the potential to bring wealth, health and education to every person on the planet. And it will be able to do this without consuming natural resources or spewing pollution into the environment. Nanotechnology is about building things atom by atom, molecule

by

molecule.

The goal of nanotechnology is to build tiny devices called nanomachines. To build things on such a small scale, you have to be able to manipulate atoms individually. (i)

Nanocomputers The challenge of nanotechnology is to place atoms precisely where you wish on a structure. Scientists can now construct natural proteins and even synthesize new ones with novel properties never seen in nature. With enough understanding, we may be able to turn proteins into microscopic tools to do the jobs we want. In the future, Nanotechnology will let us take off the boxing gloves. We'll be able to snap together the fundamental building blocks of nature easily, inexpensively and in most of the ways permitted by the laws of physics.

DRAWBACKS : Proponents predict that nanotechnology will ignite the industrial revolution of the

21st century, the effects of which will have a greater impact on the world’s population than antibiotics, integrated circuits, and human-made polymers combined. Now that scientists have the tools and are developing the skills to manipulate nature’s building blocks, nanotech enthusiasts tout some mind-bending scenarios.
