A nanometer is one-billionth of a meter or about the width of ten atoms. A single human hair is about 80,000 nanometers wide. Recent scientific advances mean that machines and materials are starting to be constructed on this phenomenally small scale.
Thinking small The concepts behind nanotechnology were first discussed in 1959 by American physicist RichARd FeynmAn in his talk “There’s Plenty of Room at the Bottom.” He urged scientists to think small and build technology out of atoms.
Scientists started at the micRoscAle, measured in thousandths of a millimeter, building motors, gears, electronic circuits, and even sunglasses for houseflies! Microprocessor chips found in smartphones and PCs feature millions of switches and circuits etched onto a circuit board smaller than a fingernail.
