Problems Encountered While Walking Along the Street

If you walk along the street you will encounter a number of scientific problems. Of these, about 80 per cent are insoluble, while 191/2 per cent are trivial. There is then perhaps half a per cent where skill, persistence, courage, creativity and originality can make a difference. It is always the task of the academic to swim in that half a per cent, asking the questions through which some progress can be made.
