Some years ago, Professor Struwe gave lectures in Analysis at the Federal Institute of Technology (Zurich, Switzerland). One day, after talking 20 minutes about a subject, he asked the students: "Who of you has already heard something about that ?" Only a few students held up their arms. On which Struwe cried out in despair: "That few? But I've explained it to you *JUST NOW* !!!"
