Earlier I have written about the  Evolution of Technology , in which I have talked about how inventions and innovations have happened to develop new technology and ideas in the past . Now in this blog I am going to talk the Miniaturization of technology in day-to-day term we call it 'Nanotechnology'.   This nanotechnology is the new upcoming ideas towards the future. It has already passed several steps, and yet it is in the process of refinement. Nanotechnology can be defined as a branch of technology and deals with dimensions and tolerance of less than 100 nano-meters, especially the manipulation of individual atom or molecule.  and engineering of functional or as engineering of functional system at the molecular scale. Some experts may still insist that nanotechnology can refer to measurement or visualization at the scale of 1-100 nano-meters, but a consensus seems to be forming around the that control and restructuring of matter at the nano-scale is a nec...

Ancient Greek Philosopher Plato had once said that 'Necessity is the Mother of Invention'; means difficult/different problems and situations require whole new thoughts and ideas to counter it. These new ideas help in the invention or innovation, creation or development of machines, devices and computers, above all factories (where are these can be made or manufactured).
