Nanotechnology is hardly comprehensible by the average human mind, because it is in a completely different dimension. Somewhere at the molecular and atomic level. Do you remember the micro-sculptures in the eye of a needle? Compared to the nanometer, the basic unit of measurement in nanotechnology, these are still huge. A nanometer is a million times smaller than the length of an ant. A sheet of paper is about 100, 000 nanometers thick. The ratio of the Earth to a child’s marble is roughly the ratio of a meter to a nanometer.
Essentially, nanotechnology comprises science, engineering and technology conducted at the nanoscale, which is about 1 to 100 nanometers. It is basically manipulating and controlling materials at the atomic and molecular level. Amazing, right?
