    • 3. “ As soon as I mention this, people tell me… about electric motors that are the size of a finger nail, and that there is a device on the market which can write the Lord’s prayer on the head of a pin. “But that’s nothing; that’s most primitive” I want to discuss the staggeringly small world below.” Richard P. Feynman (1959) “ What I want to talk about is the problem of manipulating and controlling things on a small scale.” “ There is Plenty of Room at the Bottom”
