The Beginning

To begin, "nano" is actually a prefix that comes from the Greek word for dwarf.

It simply means one billionth. So, one nanometer
(1 nm) is one billionth of a meter.


This is how nano is represented mathematically. Ten to the negative 9th equals one billionth or 1/1,000,000,000.

There are three important "nano" terms to consider when you're trying to understand the increasing news coverage and scientific developments in the field of nanotechnology. These terms are: Nanoscale, Nanoscience and Nanotechnology.
