Issue 17 of Nanooze: What is small? A nanometer is 1/1,000,000,000 (1 billionth) of a meter.
Pluck a hair out of your head (one please) and look at it. A hair is 100,000 nanometers wide. Back about 20 years
ago, the smallest transistor in a computer chip was about 100 nanometers. Today, there are transistors as small as five
nanometers. That means that 20,000 modern transistors would fit across the width of a hair!
