LIFE ON THE NANO LEVEL

In 1965, engineer Gordon Moore predicted that the number oftransistors on an integrated circuit -- a precursor to the microprocessor -- would double approximately every two years. Today, we call this prediction Moore's Law, though it's not really a scientific law at all. Moore's Law is more of a self-fulfilling prophecy about the computer industry. Microprocessormanufacturers strive to meet the prediction, because if they don't, their competitors will [source: Intel].
