writing what you don't understand

Freeman Dyson (b. 1923, British-born, American all round brilliant scientific person) said of scientific theories: "You sit quietly gestating them, for nine months or whatever the required time may be, and then one day they are out on their own, not belonging to you any more but to the whole community of scientists. Whatever it is that you produce, a baby, a book, or a theory, it is a piece of the magic of creation. You are producing something that you do not fully understand."
