Of course, the sociology is different, and he is running for an airplane to get to the accelerator, or he is on a ship or he is in a rocket, or he is at a terminal looking at the data coming in from some satellite observatory. The activities are quite different, modulated by all the modern stuff. But what goes on in his mind and thinking is still there. Maybe there is an element of change that comes from the pressure, because the scientific community has grown so large, it may be that more young scientists feel pressured to do things too fast. I don't think so.
Science is a high-risk activity.
It's a funny way to say this. You've got to back high-risk opportunities. And high-risk opportunities means some fraction of them are going to fail. Now hopefully sometimes you learn something from a failure. Often you do.
