A detta di Sidney Coleman è così. Vi riporto parte dell'intervista fatta nel gennaio del 1977.
"Sopka:But you do enjoy working with students or do you?
Coleman:No. I hate it. You do it as part of the job. Well, that's of course false...or maybe more true than false when I say I hate it. Occasionally there's a student who is a joy to work with. But I certainly would be just as happy if I had no graduate students. There are plenty of colleagues around here whom I can work with. There are plenty of research fellows; junior faculty. This is true all through the Cambridge area. There's not only Harvard, there are people to work with at MIT, at Brandeis, and there are some good people at places like Northeastern...places loaded with physicists to collaborate with, to talk about physics ideas with, who are ready and KNOW basically how to do research. You know who's good and who's bad. It's not a question of their being embryonically possibly good or possibly rotten. So certainly if I want physicists to collaborate with I don't have to have graduate students. Occasionally there is a graduate student who is a joy to collaborate with. Both David and Eric were of this kind, but they were essentially almost mature physicists. They were very bright by the time they came to me. In general, working with a graduate student is like teaching a course. It's tedious, unpleasant work. A pain in the neck. You do it because you're paid to do it. If I weren't paid to do it I certainly would never do it.
Sopka:I guess your remark means then that you would like to avoid teaching undergraduate courses or even required graduate courses...
Coleman:Or even special topics courses. Teaching is unpleasant work. No question about it. It has its rewards. One feels happy about having a job well done. Washing the dishes, waxing the floors (things I also do on a regular basis since I'm a bachelor) have their rewards. I am pleased when I have done a good job waxing the floor and I've taken an enormous pile of dirty dishes and reduced them to sparkling clean ones. On the other hand, if I didn't have to, I would never engage in waxing the floors, although I'm good at it. I'm also good at teaching; I'm considered very good at teaching, both by myself and others. And I'm also terrifically good at washing dishes, in fact. On the other hand, I certainly would never make a bunch of dirty dishes just for the joy of washing them and I would not teach a course just for the joy of teaching a course...."
