Suppose I knew the answer to world peace.Would you think I’m a kook?Suppose I knew how to power cars and computersby synchronizing the spins of subatomic particles.Would I have the equipment to prove it?Suppose I could end disease with good advice.Would you do as I tell you?Jugglers learn to drop things to make their act look difficult.Housewives measure the power of vacuum cleaners in decibels.Certain problems must remain—until better problems can be found.
