You’re obviously all trying to, you know, discover the secrets of nature, or however you like to put it. And in principle, you’re all supposed to work together and help each other. And a lot of cooperation does go on in science, but there’s necessarily a degree of rivalry. First of all, mainly it’s because of reputation, because people want to have the reputation. And unfortunately it’s usually the person who does something first who gets it, not always. Sometimes somebody’ll do something first and then someone will come along and do it very much better. But in general, it’s the person who does it first so there is this element of a race that comes into it. And some people are a lot more competitive than others. Some people are over-competitive; they have what’s called Nobelitis. They look as if they're trying too hard to get a Nobel Prize. That isn’t thought- highly regarded. And so you get- get this strange mixture of cooperation and rivalry. You get it to some extent, you know, between the armed forces, which are supposed to cooperate but nevertheless have a degree of rivalry. I mean, the Air Force against the Navy and the Army and so on. There’s always that- that sort of tension there. Or even one regiment against another regiment in the Army. So it’s- it's what you would find in most walks of life, but- but the general public is apt to overstress, I think, the competitive nature and not recognize how much cooperative work there is - people, you know, exchanging ideas and giving each other material and so on. Usually, it’s acknowledged. It’s polite to acknowledge it or make the person a co-author if they’ve done a substantial part, significant part of the work and so on. Very difficult to convey the exact balance. And unfortunately, it’s got more competitive recently because there are more scientists and there are more good scientists and the techniques are better. And many of them are worthy of support, but because they’ve grown so much, they now need large sums of money, even in biological sciences where they don’t need enormously expensive apparatus like these supercolliders, whatever it may be, but they do need apparatus and things. And that’s- that's become an appreciable part or a noticeable part of- of the national budget. So you can’t just- can't go on increasing indefinitely. And it's-it’s unclear just what level science should be supported because you can argue from different points of view.
