Waiting is a large part of living. Great, passive, negative chunks of our time are consumed by waiting, from birth to death. Waiting is a special kind of activity - if activity is the right word for it - because we are held in enforced suspension between people and places, removed from the normal rhythms of our days and lives.
It seems that I have always been ahead of my time. I had to wait nineteen years before Niagara was harnessed by my system, fifteen years before the basic inventions for wireless which I gave to the world in 1893 were applied universally.
There are works which wait, and which one does not understand for a long time; the reason is that they bring answers to questions which have not yet been raised; for the question often arrives a terribly long time after the answer.
