Richard P. Feynman (1918-1988) As soon as I mention this, people tell me about miniaturization, and how far it has progressed today. They tell me about electric motors that are the size of the nail on your small finger. And there is a device on the market, they tell me, by which you can write the Lord's Prayer on the head of a pin. But that's nothing; that's the most primitive, halting step in the direction I intend to discuss. It is a staggeringly small world that is below. In the year 2000, when they look back at this age, they will wonder why it was not until the year 1960 that anybody began seriously to move in this direction….. It is remarkable that given enough time, the synthetic chemist can usually synthesize what they set out to make. http://www.zyvex.com/nanotech/feynman.html Acc. Chem.
