Conclusion

Abstract

AbstractFirst of all, I’m here over my own strong objections. When I saw the program I wrote to Massimo and said that I’m not the right person to do this so somebody else ought to, and I suggested that he ought to because he’s the one person who covers all of these topics and I don’t. But he’s very persuasive, so I fell for it, and that just made it even worse. He said I should go on as long as I liked. My children used to have a line; if they asked a question they used to say, “Please, just the five-minute lecture.” So I’ll just go on until you shut me up.
