The study and application of extremely small things, nanotechnology can be used across all the other science fields, including chemistry, biology, physics, materials science and engineering. And while it’s difficult to imagine just how “small” these things are, and the official definition of a nanometer is a billionth of a meter, these examples may help:
- There are 25,400,000 nanometers in an inch
- A sheet of newspaper is about 100,000 nanometers thick
- If a marble was a nanometer, then one meter would be the size of the earth
