Nanotechnology

Nanotechnology is the Science and engineering at the scale of atom and molecule. It is all about rearranging of atoms and molecules. If we rearrange the atoms in coal we can make diamond, if we rearrange the atoms in sand and add some other trace elements then we can make computer chips, if we rearrange atoms is dirt, water and air we can make potatoes.
Nanotechnology is amazing, interesting and unbelievable which shocks the man of 21st century. It is worth pointing out that a word "nanotechnology" has become very popular and is used to describe many types of research where the characteristic dimensions are less than about 1000 nanometers. For example, continued improvements in lithography have resulted in line widths that are less than one micron: this work is often called nanotechnology.
