" I have mentioned an analogy and I mean it . The analogy of flying 100 years ago. At that time the question was to understand a very difficult subject, namely the subject of hydrodynamics and in particular the subject of turbulent hydrodynamics. We are now similarly trying to understand the subject of magnetohydrodynamics. [...] I personally believe that there will be such a time, but that there will be surprises on the basis of the general situation of questions of new facts which we shall learn by the very kind of experimentation which we are undergoing today . Today we are not even clever enough, I believe, to recognise the surprise if it came along. We haven't started to ask, the really significant questions and we have, to go farther on the straight forward way, and it is not coincidence that we are all going more or less in that direction. "
