Louis Ignarro: I ask them about their research and what they’re doing. And of course I talk to their professors first, because I don’t want to embarrass anybody. And then I say, “Okay, you’re doing this. Let me explain to you what I did.” So I would explain to them what I did, and they would always have questions. How did you know about nitroglycerine and nitric oxide? How did you know to look to see if arteries make nitric oxide? How did you know to look in the nerves to see if they release nitric oxide as a neurotransmitter? How did you know? I said, “I didn’t. I just developed this idea, and this was thinking outside the box. And I went and I tested that hypothesis.” So what I try to do, and it’s very difficult, is look at their research, and then suggest to them what they might do in thinking outside the box and go maybe in this direction in addition to this direction. I’ve been doing that for about almost ten years at three different universities. And in several cases it’s worked out very well. The graduates have done better, and they’re very appreciative, they’re very happy and so on. But it’s hard. It’s hard to teach somebody to think outside the box. It’s something that almost comes naturally. It’s very hard to instill in someone.
