A Quote by J. E. Littlewood on belief, certainty, change, practice, research, teaching, and trouble
In passing, I firmly believe that research should be offset by a certain amount of teaching, if only as a change from the agony of research. The trouble, however, I freely admit, is that in practice you get either no teaching, or else far too much.
