NanoFacts

•  Nanotechnology uses a basic unit of measure called a “nanometer.” Nanometer is a metric word derived from “nano,” the Greek word for “midget.”

•  Did you know that one nanometer equals one millionth of a millimeter? That means there are one billion nanometers to a meter.

•  Each nanometer is only 3-5 atoms wide!

•  One nanometer is approximately 40,000 times smaller than the width of an average human hair.

•  The first mention of nanotechnology (not yet using that name) occurred in a speech given by Richard Feynman in 1959 that was entitled, “There's Plenty of Room at the Bottom.”

•  The term “nanotechnology” was created by Tokyo Science University Professor Norio Taniguchi in 1974.

•  One inch equals 25,400,000 nanometers.

•  A human red blood cell is over 2,000 nanometers long – that is almost too long to be on the nanometer scale!
