On one occasion you were involved in discussions on banning weapons in space. Tell us about that. It's quite true that scientists are important in international relations. Science is a social affair in the sense that everybody interacts, and it's a universal thing. If you discover the right science, it applies to everybody.
People like to try to understand and learn from each other.
If somebody over here has discovered something, it's important for you to know that and what it is. And scientists can talk to each other then and trade ideas in a friendly way on scientific problems. This means they're really internationally minded. So they're eager for their scientists to be in contact with scientists in other countries. And vice versa, for that matter.
