From the Bottom Up and the Top Down

While nanoscientists study matter on an atomic and molecular scale, nanotechnologists develop materials and devices 100 nanometers or smaller in one or more dimensions. [A nanometer is one billionth of a meter, or the comparative size of a marble to the earth; a meter is about three feet.] Since it began in the 1980s, their work has advanced on two tracks – controlling self-recognizable/self-assembling molecular components and scaling down larger entities without atomic-level control. The seemingly infinite number of potential applications will impact multiple fields: robotics, medicine, electronics, and geo-engineering are just a few. The Air Force is pushing the leading edge of research and development.
